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.
11. 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.
