Recover and Recycle Refrigerants Never release refrigerant to the atmosphere!
It is an offence in Australia to do so. Always recover, recycle and reuse
refrigerants. When removing from the system, properly contain and identify
refrigerants in its dedicated container for proper disposal and/or storage.
Always consider the recycle or reclaim requirements of the refrigerant before
beginning the recovery procedures. Obtain a chemical analysis of the
refrigerant if necessary. Refer recovered refrigerant and acceptable
refrigerant quality to existing standards and regulations.
Refrigerant Handling and Safety Consult the refrigerant manufacturer’s safety
data sheet (SDS) for information on proper handling and to fully understand
health, safety, storage and disposal requirements. Use the approved
containment vessels and refer to appropriate safety standards. Comply with all
applicable transportation standards when shipping refrigerant containers.
Service Equipment and Recovery Procedures Always use refrigerant reclaiming
equipment in order to minimise refrigerant emissions. Use equipment and
methods which will pull the lowest possible system vacuum while recovering and
condensing refrigerant. Equipment capable of pulling a vacuum of less than 500
microns is required. Do not open the system to the atmosphere for service work
until refrigerant is fully removed and/or recovered. Perform refrigeration
system evacuation, prior to charging, in accordance with AIRAH / IRHACE
Refrigerant handling code of practice. Let the unit stand for 1 hour and with
the vacuum not rising above 500 microns. A rise above 500 microns indicates a
leak from the system and a leak test is required to locate and repair any
leak.
CAUTION A leak test is always required on any repaired section of the
refrigeration system.

Pressurize the system to 2500kPa in stages. A recommended pressure test is to
be performed for no less than 1 hour at 2500kPa.
NOTES · Any non-condensable product left in the system can cause the pressure
in the high side of the system to increase and in
turn, the compression temperature to rise. · Moisture will result in adverse
reaction in the refrigerant circuit. · The POE oil used in the R-410A
compressor is hygroscopic, which means that it absorbs moisture from the air.
To
prevent chemical reactions in the system, any moisture must be removed at all
costs. · Oxygen (air) reacts with the compressor oil and can lead to faults
such as compressor failure.

18. Refrigerant Charging
· The units detailed on this guide are factory charged with R-410A
refrigerant. Should there be need to add or remove refrigerant, it is
recommended to follow the charging method explained below.
· Never allow R-410A refrigerant to vent into the atmosphere. It is an offence
to release refrigerant in Australia. Always reclaim refrigerant using
equipment and container dedicated for R-410A system use only.
· All work must be carried out in accordance with Australia and New Zealand
refrigerant handling code of practice. · Only qualified technicians are
allowed to perform any work described in this guide and specifically work
related to
addition or removal of refrigerant. · R-410A refrigerant must always be
charged in liquid state. · Only during the compressor running condition the
system can be charged through the suction service port on the
compressor suction line. · Changes in refrigerant charge must be noted to a
label that is fixed to the unit for future reference.
CAUTION
The system of this unit operates with POE oil that rapidly absorbs moisture.
The maximum time any system can be opened to atmosphere is 15 minutes.

Cooling and Heating Operation:
Adjust the refrigerant charge to obtain the correct superheat and subcooling
for optimal performance as follows:
1. Ensure that air filters are fitted and total system airflow is achieved.
(Air filters are not supplied with the unit, it is the responsibility of the
installing contractor to provide and fit adequate return air and outside air
filters).
2. Connect service gauges to the schrader valves. 3. Start the unit in cool
mode ensuring that compressors are in 100% operation before taking service
gauges reading.
Allow the system to stabilise for next 15-30 minutes before recording.
Record the discharge pressure, suction pressure, liquid line temperature and suction line temperature for all of the refrigeration circuits:
Discharge Pressure = ____ kPa
Suction Pressure = __ kPa
Liquid Line Temperature (LLT) = ____ °C
Suction Line Temperature (SLT) = ___ °C
NOTE Accurate pressure and temperature measuring tools should be used to achieve satisfactory results.

- Use weighing scale when adding or removing refrigerant charge.
NOTE
For illustration purpose only. Valve location may vary depending on unit
model.
Checking for Subcooling:
1. From the R-410A Pressure/Temperature Chart record the corresponding
Saturated Condensing Temperature (SCT) at the given discharge pressure.
2. Calculate the system subcooling using the formula below: Subcooling = SCT
– LLT
3. If subcooling is within the range (see charging table), there is no need
to add/remove refrigerant. · If subcooling is lower than minimum, the system
is undercharged, it is necessary to add refrigerant. · If subcooling is higher
than maximum, the system is over charged . It is necessary to remove
refrigerant.
Allow the systems to stabilise (15-30 mins) and repeat the step 1-3 until
subcooling falls within the range specified in the Subcooling and Superheat
Table .
Checking for Superheat:
Maintaining the correct superheat is important for ensuring the evaporator is
achieving maximum capacity and avoiding excessive liquid refrigerant returning
to the compressor.
1. From the R-410A Pressure/Temperature Chart record the corresponding
Saturated Suction Temperature (SST) at the given suction pressure.
2. Calculate the system superheat using the formula below: Superheat = SLT

3. If superheat is within the range (see charging table below), there is no
need to add/remove refrigerant. · If superheat is lower than minimum, it means
that liquid refrigerant may be returning to compressor. It is necessary to
remove refrigerant or check EEV settings.
· If superheat is higher than maximum, it means that refrigeration capability
of evaporator is not fully maximised. It is necessary to add refrigerant
charge or check EEV settings.
Allow the systems to stabilise (15-30 mins) and repeat the step 1-3 until superheat falls within the range specified in the table below.

Cleaning the Condenser Coils
Clean the coils at least once a year or more frequently if unit is located in
a dusty and dirty environment, in order to maintain your system’s proper
operating performance. High discharge pressures are good indication that the
coils need cleaning. When using detergent or solvents to clean the coils,
follow the manufacturer’s instructions to avoid potential damage to the coils
and to the unit.
To clean the refrigerant coils, use a soft brush and water spray, such as
garden hose or pressure washer with low pressure nozzle.
WARNING Do Not Use High Alkaline Detergent! When using detergent for coil
cleaning, ensure that the alkaline level is no higher than 8.5, which can
cause corrosion damage to the coils.
No Water into the Drive! Ensure consideration is given to the possibility of
water entering the electrical compartments during cleaning of the condenser
coil.
Coil Cleaning Procedures · Disconnect power to the unit. · Remove the louvered
panels from the unit to gain access to the air inlet side of the coils. · Use
a soft brush to remove loose dirt and debris from both sides of the coils. ·
Straighten bent coil fins with fin comb. · Prepare the detergent solutions
according to the manufacturer’s instructions. · Spray solution at a 90o angle
to the coils, keeping a minimum nozzle spray angle of 15°, with at least a
1800mm
distance from the coils and 600 psi pressure. · Spray leaving air side of the
coils first then the air inlet side. Allow the solution to stand on the coils
