Installation procedure
A. Charging amount when out of factory excludes the refrigerant in the pipe.
B. The unit only is charged the standard volume of refrigerant (distributing pipe length is 0m).
Additional charging amount=actual length of liquid pipe x additional amount per meter liquid pipe
Additional charging amount=L1×0.35+L2×0.25+L3×0.17+L4×0.11+L5×0.054+L6×0.022
L1: total length of 22.22 liquid pipe L2: total length of 19.05 liquid pipe
L3: total length of 15.88 liquid pipe L4: total length of 12.7 liquid pipe
L5: total length of 9.52 liquid pipe L6:total length of 6.35 liquid pipe
Note:
For YV2VYH010KAR-D-X, when pipe diameter is
6.35, if the pipe length is within 15m,
additional refrigerant is unnecessary.
To prevent the different oil 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.
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 central stress, fix the pipe for every 2-3m.
Gas pipe and liquid pipe should be heat insulated separately.
Liquid pipe shall be heat insulated at all times and the only
exception when the customer is totally sure the unit will only
deliver COOLING.
The material for gas pipe should endure the high temperature
over 120
℃
.That for liquid pipe should be over 70
℃
.
The material thickness should be over 10mm, when
ambient temp. is 30
℃
, and the relative humidity is over 80%,
the material thickness should be over 15mm.
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.
Note:
Fix the refrigerant pipe
