•.Should.it.be.necessary.to.add.or.recover.refrigerant,.do.it.always.in.lIQUID.phase,.never.in.gas.or.vapour.phase.since.this.would.cause.wrong.mixing.conditions.
•.Due.to. its.high.pressure.and.quick.evaporation,.refrigerant.R410A.cannot.be.kept. in. liquid.phase.inside.charge.cylinder.because.bubbles.would.form,.making.reading.difficult.
•.Repair.immediately.any.refrigerant.leak.
•.never.overcharge.the.system.
•.never.use.compressor.as.a.vacuum.pump..
•. If.symptoms.of.refrigerant.loss.appear.during.operation,.it’s.necessary.to.carry.out.a.leak.test...leak.detec-tors.usually.employed.with.CFC.and.HCFC.cannot.be.used.with.R410a,.due.to.chlorine.in.its.composition...A.leak.detector.for.R134A.may.be.used.but.the.sensibility.will.be.lower.(when.sensibility.is.1.for.R134A,.it.falls.to.0,6.for.R410A)..
•.to.find.small.leaks,.you.will.need.a.detector.for.HCF..Sensibility.for.R410A.is.approx..23.grams.per.year.
•. If.a.gas.leak.is.found,.it.will.be.necessary.to.remove.and.completely.recover.the.refrigerant.charge..pressurize.the.system.with.dry.nitrogen..If.no.leakage.is.detected,.then.do.the.vacuum.and.charge.again.with.refrigerant..
WARNING!
Never use oxygen to carry out leak tests. Oxygen reacts violently when in contact with oil and could cause an explosion resulting in damage, personal
injuries or even death.
WARNING!
If it’s necessary to make welding operations, you must fill the circuit with dry nitrogen. Combustion of R410A refrigerant generates toxic gases.

DRAINAGE
• Indoor drainage (of condensate water) has a 3/4” MPT connection.
• Condensate drain line diameter should be equal or larger than the unit connection depending on pipe length and general building configuration.
• Drainage line should have a minimum inclination of 2% for proper water evacuation.
• When drainage line is exposed to temperatures below 0ºC, it is necessary to provide thermal insulation or electrical heating wire to avoid water freezing and tube damages
• It is advisable to install a trap with proper dimensions.
AIR DUCTS - Air duct dimensions will be determined according to the airflow and available static pressure. - Ducts must be designed by qualified technical people. - Use ducts made of non-inflammable materials in order to avoid any emission of gas in case of
fire. It is advisable to use metal plate duct with insulation. - Use flexible ducts to connect air ducts into the unit and thus avoid vibration and noise
transmission.

To line up motor and fan pulleys:
1. Loosen setscrews from the fan pulley. 2. Slide the fan pulley down the axe and line up with the motor, using a ruler to make sure
that it’s in parallel with the belt. 3. Tight the fan pulley using a tension adjuster crew.
COMPRESSOR LUBRICANT - Compressors with R410a refrigerant use synthetic polyester oil, each manufacturer using a
specific oil for his product. - The system must not remain open to the atmosphere more than 15 minutes. - Due to its hygroscopic qualities, you must be very careful during manipulation: when synthetic
oils mix up with mineral oil, they deteriorate causing obstructions and even the breakdown of the compressor. Do not mix them under any circumstance.

REFRIGERANT LINES
REFRIGERANT CIRCUIT Split systems demand a correct disposition of refrigerant piping and a correct connection between both indoor and outdoor units. Line selection should be done according to the following criteria: - Pressure drop of the line - Circulation speed of the refrigerant - Refrigerant mass DISCHARGE LINE In heat pump operation, the gas line works as discharge line.
WARNING!!! When working with the machines in operation, discharge line temperature is very HIGH and
could result in burns.
TRAZADO DE LÍNEAS 1. When indoor unit is at a lower level than outdoor unit: It is not essential to install traps in the
vertical line. However, it could be convenient to install some every 6 to 9 meters in order to help oil return.

NOTES :
- Refrigerant lines should be as short and straight as possible. Use recommended diameters to reduce quantity of refrigerant in the system.
- Fasten the tubes to fixed elements by means of braces to avoid vibration. - Carry out welding works in dry nitrogen atmosphere inside the line to be welded -USE A
BOTTLE WITH PRESSURE REGULATOR- to avoid the appearance of oxide and to expel rest of polluting material or humidity. Use rods with a minimum 15% of silver alloy.
- Insulate suction line in order to avoid condensation. Liquid line will be insulated only when exposed to high temperatures (solar radiation, etc.)
- Horizontal segment of suction line: 4% pitch towards the compressor. - In addition to refrigerant, sometimes it’s necessary to add oil. For more than 25 meters,
add 30 grams. - When height difference is more than 30 meters, it may be necessary to install an oil
separator on discharge line. - If liquid line is descendant and there is a considerable height difference, you have to
compensate the excess pressure before the expansion. - If liquid line is ascendant and there is a considerable height difference, the formation of gas
refrigerant before the expansion must be avoided. - If you should not find the chosen pipe diameter, you can use the immediately lower
diameter. The system will function normally only with a slight reduction of performance.
CCHA/ECHA – CCHBA/ECHBA Installation, operation and maintenance instructions
22
REFRIGERANT CHARGE
WARNING!!! It is forbidden by law to expel refrigerant into the atmosphere; therefore, it is necessary to
recover all the refrigerant and to avoid leaks.
- Units CCHA-CCHBA y ECHA-ECHBA are supplied with nitrogen charge. Before proceeding to any welding work, it’s necessary to remove this charge out of the interconnection lines. Once you have finished, make the vacuum and charge with the right amount of refrigerant.
WARNING!!! Never use oxygen to carry out leak tests. Oxygen reacts violently when in contact with oil and
could cause an explosion resulting in damage, personal injuries or even death.
• Should it be necessary to add or recover refrigerant, do it always in LIQUID phase, never in gas
or vapour phase since this would cause wrong mixing conditions.
• Due to its high pressure and quick evaporation, refrigerant R410A cannot be kept in liquid phase inside charge cylinder because bubbles would form, making reading difficult.
WARNING!!! If it’s necessary to make welding operations, you must fill the circuit with dry nitrogen.
Combustion of R410a refrigerant generates toxic gases.
• Repair immediately any refrigerant leak.
• Never overcharge the system.
• Never use compressor as a vacuum pump.
• If symptoms of refrigerant loss appear during operation, it’s necessary to carry out a leak test. Leak detectors usually employed with CFC and HCFC cannot be used with R410a, due to chlorine in its composition. A leak detector for R134a may be used but the sensibility will be lower (when sensibility is 1 for R134a, it falls to 0,6 for R410a).
• To find small leaks, you will need a detector for HCF. Sensibility for R410A is approx. 23 grams per year.
• If a gas leak is found, it will be necessary to remove and completely recover the refrigerant charge. Pressurize the system with dry nitrogen. If no leakage is detected, then do the vacuum and charge again with refrigerant.

23
MAINTENANCE
WARNING!!! Before performing any service or maintenance operation, turn off the main power switch of the
system to avoid any personal injuries. Block the power switch so that nobody other than a qualified technician can switch on electrical power.
• It is advisable to do maintenance works every 1.000 operating hours as well as at the beginning of each cooling season.
• Coils: at least once a year, clean condenser coils with water and detergent, then dry with air at a pressure of 600 kPa. Never clean with wire brush.
• Fans and motors: adjust transmission belt at least twice during the first month of operation and then check every 1.000 hours. Fan and motors do not need additional lubrication.
• Drainage system: verify condition and good operation of the drainage tray. Make sure that holes at the base of the unit are not blocked so that evacuation can be properly done.
• Refrigeration circuit: check for oil refrigerant leaks, noises or system’s vibrations. Take measurements of temperatures and pressures of components and record them on the maintenance form.
• Electrical circuit: make sure that all electrical connections -wires, contactors, terminals- are properly tight. Record the measurements (volts and amperes) of each compressor and fan motor. Verify the starting current. Check the good operation of all relays, pressostats and phase sequence relay of Scroll compressor.
• Air filters: clean filters after the first 4 operating hours and then every 3 months (or even before). Wash filters in water with detergent, rinse thoroughly and let dry.
