Installation Of Drain Hose - Haier 10571570 Operation Manual

Installation procedure
5 . Refrigerant pipe
[The proper thermal insulation must be treated to gas pipe and liquid pipe. If not,
it may cause water leakage.]
The outdoor unit is not charged with refrigerant.
When connecting the pipes to unit or dismantling the pipes from the unit, do
proceed as the figure shown, use spanner and torque pincers together.
For the dimension of the cone-shaped screw nut, please referring to Table 1.
When connecting pipes, both the inner or the outside of the cone-shaped screw
nut should pasted with refrigerant oil. Use hands to twist it for 3~4 circles, then
tighten it.
According to Table 1 to confirm the fasten torque. (fasten too tight may damage
the screw nut leading to leakage)
After check if the connection pipes leaks, then perform thermal insulation
treatment, as the following figure shown.
Only use seal cushion to bind the joint between gas pipe and the insulation parts.
