• HP gas pipe, Suction gas pipe and liquid pipe should be heat insulated separately.
• The material for HP gas pipe and Suction gas pipe should endure the high temperature over 120°C. That for
liquid pipe should be over 70°C.
• The material thickness should be over 10mm, when ambient temp. is 30°C, and the relative humidity is over 80%,
the material thickness should be over 20mm.
• The material should cling the pipe closely without gap, then be wrapped with adhesive tape. The connection wire
can not be put together with the heat insulation material and should be far at least 20cm.
Heat insulation
• In operation, the pipe will vibrate and expand or shrink.
If not being fixed, the refrigerant will focus on one part to cause the broken pipe.
• To prevent the stress concentration, fix the pipe for every 2-3m.
Fix the refrigerant pipe
Note:
• To prevent the oil going into the pipe, please use the special tool for R410A, especially for gauge manifold and
charging hose.
•
Mark the refrigerant type in different colour on the tank. R410A is pink.
• Must not use the charging cylinder, because the R410A will change when transferring to the cylinder.
• When charging refrigerant, the refrigerant should be taken out from the tank as liquid state.
•
Mark the counted refrigerant volume due to the distributing pipe length on the label.
