Installation
Field piping
To ensure satisfactory operation and performance, the following points should be noted for field piping
arrangements:
•
Pipework routes must be as simple and as short as possible.
•
Avoid low points on pipework where oil can accumulate.
•
Use only clean, dehydrated refrigeration grade copper tube with long radius bends.
•
When brazing use only silver alloy rods.
•
Run braze without over filling to ensure there is no leakage into the tube.
•
To prevent oxidization, blow oxygen free nitrogen through pipework when brazing.
•
Protect the casing of the unit when brazing connections.
•
Install insulation with a minimum wall thickness of 1/2
”
on all suction lines.
•
Adequately support all pipe work at a maximum of 2 metre intervals.
Use of incorrect pipe sizes can affect system pressures/temperatures and gas velocity for proper oil return.
Important Note:
One of the main factors affecting equipment reliability and compressor service life is refrigeration
circuit contamination. During installation, circuit contamination can be caused by:
•
Brazing & Welding Oxides
•
Filings & Particles from de-burring pipework
•
Brazing Flux
•
Moisture & Air
Important Note:
The guidelines for pipe sizing and maximum lengths as shown on page 7 should be followed. All
local codes of practice must be observed in the installation of refrigerant piping.
