Wrap the piping joints with thermal insulating materials and then wrap with a vinyl tape.
Thermal insulation
Thermal Insulation piping:
a. Place the drain hose under the piping.
b. Insulation material: polythene foam over 6mm in thickness.
NOTE: Drain hose is prepared by user.
• Drain hose should point downward for easy drain
flow. Do not twist the drain pipe, leave it sticking
out or waving around, do not immerse the end in
water. If an extension drain hose is connected to the
drain pipe, make sure to be thermally insulated
when passing it through the indoor unit.
• When the piping is directed to the right, piping,
power cable and drain hose should be thermally
insulated and fixed at the rear of the unit.
Piping Connection:
a. Connect indoor unit pipes with two wrenches. Pay
special attention to the torque allowed as shown
below to prevent the pipes, connectors and flare
nuts from being deformed and damaged.
b. At first fingers-tighten them, then use the wrenches.
