Moving tubes to the moving parts; minimum clearance 12.7mm(1/2

Moving tubes to non-moving parts; minimum clearance 9.5mm((3/8

Moving tubes never touch to lead wire.
23 Avoid refrigerant migration
The refrigerant migration to compressor shell should be avoided during the heat pump water heater
system shut down periods, It
’
s suggested that the electric heating belt should be used around
the shell bottom when necessary.
24 Miscellany
（1）The compressor should be carried carefully to avoid drop, drag ,impact and should not apply
partial force on projection parts such as pipe, hermetic terminals, foot during carrying
and processing.
（2）The compressor should not be operated to form a vacuum and to absorb air. The compressor
only can run in one direction which according to lead routing wiring diagram. Never
reversion otherwise thecompressor will be in trouble.
（3）The compressor should not be left opened in the atmosphere for more than 5 minutes.
When the air entered into the unit system with refrigerant R410A, it will expedite the
deterioration of the oil and result in the capillary depositing and the reducing of
insulation resistance.
（4）Electric pulse should not be applied to compressor when it is in vacuum.
（5）The compressor should be kept in the place with low-dust, low-moisture.
