3.2 Product description

Because of their low construction height, EASYAIR®flat air handling units are intended for ceiling installation.The unit design consists of functional modules (filter, fan, silencer, heater, cooler, heat recovery). The devices can be or-dered optionally as combined supply and exhaust air systems including heat recovery or simply as air supply and exhaust air systems.The units with heat recovery achieve a high degree of heat recovery. Thus the units make a considerable contribution to energy savings and a reduction of operation costs. All units can be ordered with the appropriate control devices. This ensures trouble-free unit operation.All field devices come ready assembled with the unit. The switch cabinet comes as a separate unit and can thus be installed wherever best suits the client. The wiring installation between the unit and switch cabinet must be supplied by the client.Optional extras allow the units to be extended.Optional components to extend use consist of: acoustically isolated unit connections, dampers, electrical or water-heated heater module, cooler module, silencer module, pressure sensors for pressure or constant volume regulation, air quality sensor, room temperature sensor, etc.When using the associated control system, filter replacements which become necessary are displayed by the pressure-difference filter monitoring device. All control functions are included in the control software and their parameters can be set. By means of pre-configured bus systems, the control system can easily be integrated into higher-level systems: the user can choose between Modbus, LON, BacNet/Ethernet.

Our products are subject to constant quality control and comply with the applicable regulations.

4. Transport / preparation

4.1 Transport

� The system’s individual components may only be conveyed with the means of transport intended for this purpose.

� Only transport the system in modules; do not transport devices which have been connected together

� Do not leave or operate with suspended loads.

� Only approved hoisting equipment with sufficient load capacity may be used.

� The hoisting equipment must be in perfect condition.

� Lifting gear (slings, chains, etc) must be checked for load capacity and damage before use.

� Before lifting the devices, lock all maintenance doors!

4.2 Preparation

� Check the characteristics of the ceiling.

� Check the individual components for damage in transport.

� For the installation site, choose a place which allows easy access for servicing and maintenance.

� Care should be taken that the components and the connecting cable at the installation site can neither be damaged mechanically nor affected by oil or other aggressive substances.

� Check that security devices, contactors and circuit boards in the control cabinet are tightly secured.

� Push any loose assemblies in firmly.

� The fresh air intake is to be designed in line with the applicable standards and should be placed well away from ex-haust air or extractor outlets (kitchens, laundries, etc.)

� If possible, the expelled air should be exhausted via a roof outlet well away from fresh air intakes, windows, balconies, etc.

Attention!Components that become loose during transport can cause malfunctions or damage.

4.2.1 Space requirement

� Care should be taken to allow free access to the operating side (from underneath).

� The important thing is to allow sufficient distance so that the maintenance panel can be opened and the main components removed.

� The height of the siphon for condensate outflow tubes (optional) must be taken into account when suspending the unit from a ceiling; use a condensate pump if necessary.

4.2.2 Ceiling construction

� The devices may only be installed under horizontal, vibration-resistant ceilings.

� The design of the ceiling and the suspension construction must comply with the client's requirements on acoustics (sound insulation) and the correct drainage of the condensate.

� The ceiling construction must be able to bear the units’ structural load.

� Care must be taken that the sealing strip is not attached under tension (particularly at the corners)!

"Assembly"


AL-KO EASYAIR®flat

� Fit the cover cap included on the interior of the housing. This way the inspection openings for the click connector are closed; see Fig.: click connector / door lock.

� Hook in the mounting straps at the top of the housing and attach them to the housing with the screws provided, see Fig.: Mounting straps

� Screw a Duo-Taptite M8X25 screw into the hole of the inner mounting bracket of the "left housing", see Figure: Con-nect modules

� The assembly of the GF and PF devices starts with the heat recovery module.

� Attach the modules to the ceilings in the appropriate assembling sequence (left housing before right housing!) using the mounting brackets and suitable mounting material (noise insulation to be provided by the customer). Take note of the device structures, see Fig.: Connect modules

� Once the modules have been installed on the ceilings, connect the modules with the click-in connectors by pressing them against each other. Care must be taken that the Duo-Tapite screw threads into the bracket of the "right housing".

In order to reduce the weight of the individual modules, the components can be removed from the housings.

After loosening the covers, using the special tool included, the click connectors can be opened at any time and removed from the housing; see Fig.: click connector / door lock.

� Establish potential equalisation of the modules by connecting them using a potential equalisation bolt; see Fig.: potential equalisation

� After that, fit cover; see Fig.: potential equalisation

� Connect the entire installation to the potential equalisation

Drip separator (cooler module)


� Carefully remove the drip separator from the housing by pushing it up and sidewards in the direction of the heat exchanger and then lowering it.

5.2.3 Duct connection

For PF- and GF units the duct system channels the outdoor air into the air handling unit and into the building as supply air. The extract air is passed through the unit for heat recovery and channeled outside as exhaust air.

For EF units the duct system channels the outdoor or room air (recirculation) to the ahu and into the building / room as supply air.

Equipotential bonding between the device and the drain must be established with the grounding strip supplied.

Duct connections (optional)

Sound-isolated duct connections are available for all EASYAIR®flat units, which use the entire available unit cross-section.

These duct connections must be fixed with enclosed drilling screws to the casing.

Connection of the ducts to the unit must be properly performed.

Requirements for the duct system

The ventilation system should be designed for slow air velocities and low pressure drop to boost efficiency, energy consumption and air output.

Pulleys near the device should be avoided.

All connections between ducts and air handling unit are to be executed accurately and securely.

Condensation protection / thermal insulation

For PF- and GF units the outside and exhaust air ducts must always be well insulated to prevent condensation. It is particularly important to carefully insulate all pipelines leading directly to the unit and to cold rooms/zones.

For EF units that are used for cooling issues the supply air duct must be insualted.

Generally speaking, all air ducts carrying cold air must be insulated.

5.2.4 Siphon connection

EASYAIR®flat heat recovery and cooler modules are provided with a condensate tray and a condensate pipe in the ope-rating panel. This condensate pipe comes in the form of a snap-on coupling. This allows quick and easy connecting / disconnecting of the condensate drainage pipe to the device.

It is possible to push-fit a 14 mm outside diameter drainage tube directly into this connector.

As delivered, a short length of plastic 14 mm outside diameter drainage tube is inserted in the connector, so that it is possible to simply fit a commercial hose with 14 mm inside diameter onto this plastic hose using a hose clip.

Condensate outflow pipes must be connected to the waste-water system using an s-bend (supplied by client).

If this is not possible because of lack of space, a condensate pump (supplied by client) should be used.

In order to prevent an intake or outtake of air from the closed drainage system, the height of each siphon must be designed for the negative or over pressure of the air handling unit.

233059570

Fig: Tray with siphon connection

Height Over pressure Negative pressure

H1 25 mm 105 mm

H2 120 mm 65 mm

H3 = H1 + H2

The installation height of the siphon must be kept in mind when installing the unit.

5.3 Electrical connection

� EASYAIR®flat devices are delivered as standard without control devices and without field devices.

� As an option, the devices can be ordered with control and field devices ready installed.

� The switch cabinet is delivered as a separate unit and must be wired up by the client with the EASYAIR®flat devices.

� This enables the switch cabinet to be installed in any easily accessible place as per the client's preferences.

Warning!The electrical connection may only be performed by a licensed electrician in accordance with the regulations as well as the directives of the local power company. The connection is to be performed in exact accordance with the circuit diagram and assembly plan.

7. Enter the "AUTO Operation" menu by pressing <ENTER> and set the parameters.

If "AUTO" is switched on, the controller will constantly compare the calculated supply air target value with the outdoor temperature.

� If the outdoor temperature / supply air actual value is the same as the supply air target value, ventilation will be switched on.

� If the outdoor temperature / the supply air actual value falls below the value set in "differential heating," the controller automatically recognizes that the heat must be switched on.

� If the outdoor temperature / supply air actual value rises to the value set in "differential cooling," the system goes into cooling operation.

The "differential heating" default value is set to 2K and the "differential cooling" value to 4K .

It is normal that the actual temperature for the 2K heat demand and for the 4K cooling demand differ from the tempera-ture target value.

These values must be smaller if a more exact temperature control is desired.

Example:

� Differential heating: 2K

� Differential cooling: 4K

� Adjusted basic target value: 20 °C

Outdoor temperature 19 °C: System ventsOutdoor temperature 17 °C: System heats because the outdoor temperature / supply air actual value has fallen

below the "differential heating" value.Outdoor temperature 25 °C: System cools because the outdoor temperature / supply air actual value has risen

above the "differential heating" value.

8. Maintenance

The air handling unit operator is obligated to ensure that the system undergoes routine maintenance by trained personnel.AL-KO recommends performing maintenance according to VDI 6022 and VDMA 24186.In addition, a hygiene inspection is required every 3 years according to VDI 6022.

The AL-KO THERM GMBH assumes these tasks upon conclusion of a maintenance contract.

8.1 Safety

Attention!Installation, start-up, maintenance and repairs may only to be carried out by trained personnel!

Attention! � As a general rule, when working on the device always disconnect the power supply (disconnect all

phases).

� Only open the inspection doors when the machine is off and the fans are at a standstill. After the machi-ne is switched off, the rotor still runs for approx. 1 to 3 more minutes. Never bring the rotor to a stop by hand or other object!

� After working on the unit, the person responsible is to ensure that no persons remain in the system and that all factory-fitted protection measures are working before powering the system back up.

8.2 Consumables and replacement parts

Attention!Only use original consumables and replacement parts. Only in this way is safe operation guaranteed! The war-ranty is void in the case of non-compliance. You can find a replacement parts list in the unit documentation.

8.5 Checking components

All installed components are to either be easily accessible for inspection or extractable after removing the maintenance doors from the unit.

The objective of regular hygiene checks is to detect and eliminate hygiene issues early on through frequent visual inspec-tions or random microbiological checks.

Regular hygiene control includes the following measures:

Visual inspection of the unit for hygiene issues such as bacterial growth or contamination, rust build-up, calcium deposits and damage.

Components identified as dirty during the hygiene inspections must immediately be cleaned.

8.5.1 WWe / KWK

Attention!The use of high-pressure washers with conventional jet nozzles is not permitted due to risk of damage!

Corrosion may occur in the heat exchangers after longer periods of downtime due to sulfate-reducing bacteria. These sulfides aggressively corrode welded joints and copper-based material.

We recommend the following measures to reduce this type of copper corrosion:

� Using sulphate-free water in the entire circuit

� Ensuring there are no leaks in the system.

� Avoiding long periods of downtime for filled circuits.

� Avoiding frequent re-filling with fresh water.

� Using material-tolerant inhibitors or biocides.

8.5.2 Plate heat exchanger

The heat exchanger can be cleaned with a hot-water, high-pressure cleaner. The following parameters must be met:

Nozzle: Flat jet nozzlePressure: max. 20 barAmount of water: max. 450 l/hWater temperature: max. 70 °CDistance from the heat exchanger: min. 30 cmNozzle direction: 90° offset to the foil stamping or blades

"Maintenance"


AL-KO EASYAIR®flat

Attention!The specified values must be met, otherwise the plate heat exchangers may be damaged.

Cleaning agents (i.e. all-purpose cleaners, biodegradable) may be used to remove stubborn dirt. Plenty of fresh water must be used for rinsing afterwards!Do not use any aluminum cleaners! They are acidic and corrode the surfaces of the plate heat exchanger.

8.5.3 Dampers

Regularly clean dampers.

Attention!When the dampers close, do not reach inside the slats with your hand during operation or servicing. Danger of crushing!

8.5.4 Drip separator

The drip separator can be pulled out for maintenance reasons.

8.5.5 Fans

Regularly clean ventilation rotors, the motor and the motor base.

8.6 Replacing components

8.6.1 Replacing filter bags

Filter bags are generally to be replaced once they have reached the permissible end pressure difference.

Do not wash out and reuse used air filters. They must always be replaced with new air filters. The hygienic requirements will not be met otherwise!

� Open or unhook the operating panel; see "5.1 Opening / removing the operating panel"

� The filter can be pulled downwards out of the housing by pulling on the filter bag frame.

� Clean and inspect the filter seals. Replace any damaged seals.

� Insert new filter bags and hold them in place by spanning them across the filter frame.

Attention!Only use original consumables and replacement parts.

Safe operation can only be ensured in this way. The warranty may be invalidated!
