• The drain pipe should be installed per this manual to
ensure proper drainage. The pipe should be well insulated
to avoid condensation. Inadequate installation may lead to
water damage.
• Both liquid pipe and the vapor pipe should be well
insulated. Inadequate insulation may lead to system
performance deterioration or condensate formation.

of an external timer or separate remote-control system
• The equipment should be checked for current leakage
after installation and power-up.
• Water or moisture may discharge from the equipment
when relative humidity rises above 80%, when condensate
drain lines become blocked or when air filters become
blocked or heavily soiled.
3-minutes protection To protect the unit, there is a
