Insulation Of Refrigerant Pipe - Ouellet CCD12KCHVS-I Owner's Manual

torque wrench
indoor pipe
• Wrap the indoor pipe and joint of connection pipe
with insulating pipe, and then wrap it with tape.
CAUTION
• During the connection of the indoor unit and the refrigerant pipe, never pull any joints of the indoor
unit by force; otherwise the capillary pipe or other pipes may crack, which would result in leakage.
• The refrigerant pipe should be supported by brackets. Do not let the unit withstand the weight of it.
• If the pipe diameter of the outdoor unit doesn't match the piping connection size of the indoor unit,
use the piping connection size of the indoor unit and add the adaptor supplied with the indoor unit.
• The bending degree of the pipe cannot be too small; otherwise it will crack.
• Use a pipe tube bender to bend the pipe.

INSULATION OF REFRIGERANT PIPE

• The refrigerant pipe should be insulated with insulating
material and wrapped with tape in order to prevent
condensation and water leakage.
• The joints of the indoor unit should be wrapped with insu-
lating material and no gap is allowed as shown opposite.
• Wrap the pipe with tape.
• Bundle the refrigerant pipe and electric wire together with
tape, and separate them from the drain pipe to prevent the
condensate water overflowing.
• Wrap the pipe from the bottom of the outdoor unit to the top of the pipe where it enters the wall.
During the wrapping, the later circle should cover half of the former one.
• Fix the wrapped pipe on the wall with clamps.
• Stuff the gap between pipes and wall hole with sealing gum.
CAUTION
• Once the pipe is well insulated, never bend it to a small angle. Otherwise it will crack.
• Do not wrap the pipe too tightly; otherwise the insulation effect would be weakened.
• Make sure the drain pipe is separated from the refrigerant pipe.
