Condensate drain pipe installation:
• For easy drainage of condensate water, drain pipe must be sloped
downward at least at a gradient of 1:100.
• The drain pipe must have a U-bend.
• Drain pipe that runs under the ceiling or within the air conditioned
space should be insulated to prevent condensation of water.
Choice of insulation material can be PE, PU or other appropriate
insulation material.
Air Ducting Installation
• There are two types of discharge air-duct, namely rectangular and round ducts.
• Rectangular ducts can be connected to the discharge of the indoor unit directly. Refer to the dimension
drawing of the unit to see the dimensions of the discharge.
• Flexible connection must be installed between air ducts and indoor unit to ensure quiet operation.
• A reducer is necessary to connect the round duct to the discharge of the unit.
• Design of supply and return air duct should strictly adhere to the maximum static pressure that can be
delivered by the unit to avoid unsatisfactory unit performance and overload of fan motors.
2. Outdoor Unit Installation
To ensure the unit operates at optimum performance level and to maintain long life-span of components, the
choice of location of unit and installation recommendations as listed below should be followed:
• The discharge air and intake air direction of outdoor unit should not be blocked to ensure there is no
short circuiting of hot air.
• If there is more than 1 unit being installed at the same location, make sure that the discharge of one unit
does not face the air intake of another.
• The location of installation should be well ventilated and avoid direct sunlight.
• Location of installation should be able to drain rain water or condensation water.
• Ensure the location of installation does not face strong wind and is free from dust.
• Do not connect duct to the outdoor fan discharge.
• Do not install the unit at location that is near corrosive materials or chemicals.
• Avoid installing the outdoor unit under the window.
• Ensure the discharge of air and noise generated during operation do not affect the surrounding neighbors.
Note:
A U-bend must be installed along the
drain pipe. The recommendation is as
following:
100mm<h<150mm and x>h/2
