TYPICAL UNIT CONFIGURATION


FEATURES

Stellar units are self-contained and assembled on full pe-

rimeter base rails with rigging holes in the four corners for

overhead rigging. Every unit is completely piped, wired,

charged and tested at the factory to simplify the field

installation and to provide years of dependable operation.

All models are suitable for horizontal duct connections.

The power supply can be routed into the control box through

a gland in the wiring panel on the front of the unit.

Compressors are scroll type of an advanced design en-

suring high Energy Efficiency Ratio, less noise, less vi-

bration and outstanding endurance. Crankcase heaters,

internal pressure relief valve, internal compressor motor

protection.

Every refrigerant circuit includes an expansion valve, a

liquid line filter-drier, a discharge line high pressure switch

and suction line freezestat and lowpressure switch to protect all

system components.

Each supply air blower is equipped with a belt drive that can

be adjusted to meet the exact requirements of the ap-

plication. A high or low static drive option is available for

applications with a higher or lower airflow and / or static

pressure requirement. All evaporator blower motors are

weatherproof TEFC IP55 with Class F insulation.

A fixed outdoor air intake connection that is designed for

25% fresh air is available as standard. Fresh air dampers are

optional for field / factory installation.

Condenser fans are propeller type of heavy duty con-

struction, dynamically balanced and suitable for operate up

to 80°C ambient. Fans are driven by TEAO IP55 motors

with Class F insulation. The fan blade pitch Angle is

designed for maximum airflow and minimum noise.

The evaporator and condenser coils are constructed of

seamless internally enhanced copper tubes which are

mechanically bonded to aluminum fins. Heat Exchangers are

tested up to a pressure of 350 psig (evaporator) and 600 psig

(condenser).

A nonmetallic drain pan with bottom condensate removal

ensures zero water retention and no corrosion

That ensures indoor air quality (IAQ).

All cabinet panels are made from pre-plasticized sheets which

are hot dip galvanized with PVC coating providing an excel-

lent resistance to UV & corrosion. All panels are of double skin

construction provided by a “sandwich” type arrangement, 30mm

thick, comprising of 0.7 mm thick galvanized steel internal skin

with 0.7 mm thick pre-plasticized sheet outer skin and injected

with polyurethane foam of 40 kg/m3 density, providing an

overall thermal transmission coefficient of K 0.68 W/m² °K.

Panels are removable and fixed to the frame with self-tapping

screws.

All Stellar units are equipped with a control panel that

includes all the necessary operating and safety controls that

are needed for reliable operation. Compressors are protected

with internal thermal overload and fan motors with external

overload. Transformers and control circuits are protected

with fuses.

The operation of the package units is masterminded by the

microprocessor based Simplicity™ control board which

provides both intelligent monitoring and easy iagnostics,

as featured below

Anti-Short Cycle Protection: To aid compressor life, an

anti-short cycle delay is incorporated into the standard

controls. Compressor reliability is further en- sured by

programmable minimum run times. For test- ing, the anti-

short cycle delay can be temporarily over- ridden with the

push of a button.

Fan Delays: Fan on and fan off delays are fully Pro-

grammable. Furthermore, the heating and cooling Fan delay

times are independent of one another. All units are

programmed with default values based upon their

configuration of cooling and heating.

Safety Monitoring: High flow pressure switches and suction

line freezestats are supplied on all units to protect against

loss of charge and the occurrence of coil frosting. The control

board monitors the high and low pressure switches and the

freezestats. The unit control board will alarm on compressor

lockouts and repeated limit switch trips on electric heat units.

Nuisance Trip Protection: To prevent nuisance Trouble

calls, the control board uses a “three times, you’re out”

philosophy. The high and low-pressure switches and the

freezestats must trip three times within two hours before

the unit control board will lock out the associated

compressor.

On Board Diagnostics: Each alarm will energize a trouble

light on the thermostat, if so equipped, and Flash an alarm

code on the control board LED. Each high and low-pressure

switch alarm as well as each freezestat alarm has its own

flash code. The control board saves the five most recent

alarms in memory, and these alarms can be reviewed at any

time.

Nonvolatile Memory: Alarms and programmed values are

retained through the loss of power.

MAINTENANCE

The Stellar Packaged Air Conditioners are premium quality

machines with very low maintenance requirements.

Compressors used in Stellar Packaged Units are of Scroll type

and are charged with the correct amount of refrigerant and

lubricating oil. Unless there is a leak in the system, no topping

up is generally required.

All bearings used in the fan shaft, fan motor and evaporator fan

motor are permanently lubricated for life. Lubrication is

therefore not a part of the periodic maintenance schedule.

EVERY MONTH

Remove the filters and blow compressed air over them to get

rid of loose dust. Visually inspect the filters

Conditions, replace them with new ones of same sizes if

required.

Stellar Packaged Air Conditioners are provided with a specially

designed drain pan, for proper maintenance

check and clean blockages at drain connections if any.

EVERY 3 MONTHS

In addition to the monthly maintenance above, check the belt

tension of evaporator fan. A correct tension is indicated when the

belt has a relaxation of approximately 10 mm to 13 mm when

pressed lightly with a finger.

EVERY SIX MONTHS

In addition to the maintenance done every three months:

The condenser coils should be cleaned by spraying water over

it at low pressure or with a brush while ensur- ing that the fins are

not damaged.

Check all electrical connections and tighten them if required.

Clean all accessible electrical panels of dirt and dust. Before

cleaning the control panels, ENSURE that the electrical power to

the unit is switched off.

EVERY 12 MONTHS

In addition to the maintenance done every six months:

Use a proper cleaning cloth to clean fan blades and motors.

Ensure that the unit is working properly by checking, current,

voltages, pressures and temperatures.

Check the earthing or grounding of the unit.

Check the exterior of the unit for any signs of corrosion. Even

though it is highly unlikely, if any corrosion that is seen, should

be removed by proper sanding the sur- face. Repaint the unit

with proper touch up paint, available from York.

Check the unit for any unusual vibrations or noise, lo- cate the

cause and rectify it by changing mounts, base isolators etc as

required
