Installation Considerations
Protect the unit to avoid dust or other obstructions entering the unit and accessories during installation,
or whilst in storage on site. Service ports should be installed to allow access for filter maintenance.

Physical Installation
1.Installer to prepare suitable threaded hangers with adjustable nuts and gaskets.
2.Install as shown by the image above. Installation must be level and securely fastened.
3.Failure to observe proper fixing could result in injury, equipment damage and excessive vibration.
Uneven installation will also effect damper operation.
Notes for reverse installation of the unit
4.Reverse labeling shows the unit is upside down.
Ducting
1. Connection of unit vents and ducts should be taped or sealed to prevent air leakage, and should com-
ply to relevant guidelines and regulations.
2. The two outdoor vents should face downward toward the outside to prevent any rain water ingress.
(angle 1/100 1/50).
3. Insulation must be with the two ducts outside to prevent condensation.
Material: glass cotton, Thickness: 25mm
Installation Considerations

坡度1/100-1/50
Gradient1/100-1/50

1. Be sure the ceiling height is no less than the Figures in above table B column.
2. Unit must not be installed close to boiler flues.
3. Following phenomenon should be avoided in the ducting installation.
Serve bends Multiple reducers/ crimped duct
Multiple direction changes
4. Exessive use of flex-duct and long flex-duct runs should be avoided.
5. Fire dampers must be fitted as per national and local fire regulations.
6. Unit must not be exposed to ambient temperature above 40 and should not face an open fire.
7. Take action to avoid dew and frost.
As shown by drawing below, unit will produce dew or frost when saturation curve is formed from A to C.
Use pre-heater to ensure conditions are kept to right of the curve (B to B＇,to move C to C) to prevent
condensation or frost formation.
8. To avoid the outdoor exhaust air cycling back to indoor, the distance between the two vents installed
on the outside wall should be over 1000mm.
9.If heater is equipped to the unit, operation of heater should be synchronous with the unit, so that the
heater starts to work only when unit starts.
10.Duct muffler may be considered if user wants indoor noise to be minimized.
Installation Considerations
9

Power must be isolated during installation and before maintenance to avoid injury by electric shock. The
specifications of cables must strictly match the requirements, otherwise it may cause performance fail-
ure and danger of electric shock or fire.
Power supply is AC220V/50HZ/1 Phase. Open the cover of electrical box, connect the 2 wires (L/N/) to
the terminals and connect the cable of the control panel to the board according to the wiring diagram,
and join the control panel to the cable.
We do not accept any liability for any problems caused by the user’s self and non-authorized re-
engineering to the electrical and control systems.
