. Installation Information
All service technicians handling refrigerant must be licensed to handle refrigerant gases.
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. For the recovered refrigerant and
acceptable refrigerant quality refer to the existing standards and regulations.
Refrigerant Handling and Safety
Consult the refrigerant manufacturer’s Material Safety Data Sheet (MSDS) 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.
Charge refrigerant into the system only after the equipment does not leak or contain moisture. Ensure that R-410A is
only charged in liquid form. Take into consideration the correct amount of refrigerant charge specified for the system
to ensure efficient unit operations. When charging is complete, reclaim refrigerant from charging lines into an approved
refrigerant container. Seal all used refrigerant containers with approved closure devices to prevent unused refrigerant
from escaping to the atmosphere. Take extra care to maintain all service equipment directly supporting refrigerant service
work such as gauges, hoses, vacuum pumps and recycling equipment.

Step 3: Install Interconnecting Field Pipes
Braze refrigeration piping. Refer to Section 11 for details of field pipe sizes and piping installation procedure.
WARNING
Live electrical within enclosure. Isolate electrical supply before
removing panels. Authorised technicians access only.
. Field Pipe Connection
11.01. Piping and Brazing
CAUTION
The units described in this guide use R-410A refrigerant
R-410A operates at a pressure approximately 1.6 times higher than similar systems using R-22. When installing equipment
using R-410A refrigerant, there are number of standards that must be met:
• The compressor of this unit operates with Polyolester (POE) oil that rapidly absorbs moisture. The maximum time any
system can opened to atmosphere is 15 minutes, if the system is left open for extended period cap it off to prevent the oil
from absorbing moisture.
• It is important to work with absolute cleanliness.
• Brazing must be done with the use of Nitrogen to avoid carbon deposits into the pipes.
• The system must be evacuated thoroughly to 500 microns (see evacuation procedure).
• The system must always be charged with R-410A refrigerant in liquid state.
• 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.
• Only qualified technicians are allowed to perform any work described in this guide.
• All work must be carried out in accordance with Australia and New Zealand refrigerant handling code of practice.
Maximum allowable total equivalent field pipe length is 60 metres, see diagram below. This includes all the equivalent pipe
fitting loses and vertical height difference. Vertical height difference must not exceed 20 metres. Table 1 below shows the
equivalent straight pipe length of elbow fittings.

Selected field pipe sizes must match the recommended sizes in Table 2. If the installation requires different field pipe
diameter due to different application condition other than recommended, contact ActronAir for advice.
Most of unit pipe connections are factory swaged to easily fit to the recommended field pipe diameter.
When it is required to install other refrigeration devices, such as refrigerant drier, solenoid valve and the like, include the
equivalent straight pipe length of the device in the calculation of total equivalent field pipe length.
Both pipes are required to be insulated.

CAUTION
Brazed joints should only be made while purging Nitrogen through the system.
Failure to do so will cause carbon deposit to be left on the internal pipe surface, that in turn can cause system failure and void
warranty.

Installing interconnecting pipe work to indoor, nitrogen bleed procedure (First fit or rough in stage only)
1. Run interconnecting pipe work from condenser location to evaporator.
2. Release pressure in evaporator and remove caps.
3. Fit copper tube into tail, set nitro bottle and regulator up at condenser end of pipe work.
4. Fit nitrogen line into liquid line with rubber bung to seal the connection. The seal will prevent air being sucked into pipe
work.
5. Leave suction line open, set nitro regulator for nitrogen to flow through pipe work at 2 l/s flow rate @20kPa.
6. Braze required joints as quick as possible. See Diagram Above.
Installing interconnecting pipe work to outdoor, nitrogen bleed procedure (First fit or rough in stage only)
1. Starting with circuit 1 system, remove piping caps from the condenser and fit pipe work into tails.
2. Fit nitro hose onto suction ball valve and fit open hose onto liquid line post valve.
3. Set nitrogen regulator to 2 l/s flow rate through pipe work and evaporator.
4. Braze remaining joints as quick as possible.
5. Allow the brazed joints to cool and conduct leak test in the connections.

11.02. Pressure Testing
Pressurize the system to 2500kPa in stages. A recommended pressure test is to be performed for no less than 1 hour at
2500kPa.
NOTES
Importance of Evacuation:
• 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.
