Duct Working Installation
Air Supply Duct Working Installation
Two types of air supply duct working are for option: round and rectangle. Round air duct working can be
connected up to the air supply inlet directly; while the rectangle one needs to be connected with a transition
air duct to air supply inlet, and separate to the air diffuser. Pick up the selected air distributor or diffuser to
meet the application requirements.
Air Return Duct Working Installation
To connect with return air inlet of indoor units, the other end connecting with return air inlet of ceiling. Make
a sailcloth foldaway air duct, and strengthen it with 8# iron rope, in this way, the unit can be adjusted freely
depends on ceiling height.
Insulation of Duct Working
Both air supply and return duct working shall be equipped insulation material with aluminum foil.
Electrical Heater and Heating Coil Installation
The way to install electrical heater and heating coil is almost the same, both need to connect to air outlet of
indoor units as shown as followings:
Install MCK-T Series Indoor Unit
Notes:
a. Ensure the space for installation.
b. Ensure no barrier, and good ventilation is a must.

To refer to the above installation dimension to ensure the performance of units as much as possible.
The supports shall carry weight 4 times larger than the indoor units to avoid unnecessary vibration and
reduce the noise.
Installation Instruction
a. To keep indoor units from the source of heat and vapor.
b. To measure the position of fixing and drill hole in the ceiling and fix the units tightly.
c. The paper temperate shall be measure dimension before usage.
d. Ensure the paper temperate is the same dimension as hole dimension in the ceiling.
e. Before the completion of ceiling decoration, leave the paper temperate with the indoor unit.
f. Ensure the distance between the hang pole is 620.4mm×790.0mm.
g. To ensure use screw to fix the indoor units tightly.
h. To adjust distance between the bottom panel and ceiling is less than 35.0mm.
i. To check installation horizontally, and indoor units are fixed tightly without dropping off and vibration.
