User notice
During operation, the total capacity of the indoor units operating at the same time shall not
•
exceed the outdoor unit capacity. Otherwise, it will lead to inadequate indoor unit cooling
(heating) capacity.
According to the capacity, install an air switch or fuse at each indoor unit and a main air
•
switch for all indoor and outdoor units. The air switch of each indoor unit is used for short
circuit protection and abnormal overloading of the indoor unit, which is normally closed.
The main switch controls the power supply for all indoor and outdoor units. User must cut
off the main power supply for all units before cleaning.
User should keep the unit powered on. If user do not use the unit for a long term, please cut
•
off power supply and switch on the main power switch for 24 hours before operation.
When the indoor unit receives shutdown signal, the fan would keep running for 20-70s to
•
use residual cool or heat from the heat exchanger and ready for the next operation.
If operating modes of the indoor unit and outdoor unit are not in accordance, the indoor
•
unit fault indicator flashes after 5s and the indoor unit stops. In that case, just mode
conversion can eliminate the conflict. Cooling mode is in accordance with dry or fan mode,
while non modes are in accordance with heating mode.

Fix the hanging plate on the wall with screws.•
Pull the hanging plate to make sure it is fixed after installation completed. Properly installed•
hanging plate can withstand 60kg and all fixed screws are stressed uniformly.
Outlet pipe wall hole diameter: 50mm for MW(C)W509/512, and 65mm. for MW(C)W518.•
Outlet pipe wall hole Ø
Drill piping hole
Drill a outward-dipping hole (˫50 or ˫65) after determining the piping hole position.•
Install wall pipe to prevent piping and cable through the wall from damaging.•

Drainage pipe installation
The drainage pipe should be inclined downward for water flow smoothly. Wrap the indoor•
drainage pipe with thermal insulation material.
The drainage pipe can not be twisted, bulged or waved etc. Do not insert the outlet port•
into water.
Bulged
DO not insert it into water.
Twisted
Connecting pipe installation
Connect the connecting pipe and two indoor unit extraction pipes correspondingly and•
fasten the connecting pipe joint nut.
Arrange and bend the piping carefully. Do not damage the connecting pipe.•
Do not overtighten the joint nut, otherwise it may cause leakage.•
