Installation of Wall Mounting Plate • Make sure the plate is completely level by using a spirit level, if mounting plate is slanted it can hinder the smooth discharge of the condensed water. • Mark and drill mounting holes corresponding with the mounting holes in the mounting plate. • Fix the wall mounting plate firmly on the wall with screws. The method of fixing is not to depend on the use of adhesives since they are not considered to be a reliable fixing means.

INSTALLATION OF INDOOR UNIT • Pass the connection wires, connecting pipelines and drain pipe through the wall hole. • Hang the indoor unit on the hook of the top of the wall mounting plate so that the hooks at the bottom of the indoor unit match the hook of the wall mounting plate. 5. INSPECTIONS • Check if the hooks on the mounting plate and unit at the top or bottom are firmly fixed. • Check that the indoor unit is properly level.
INSTALLATION OF OUTDOOR UNIT • Use caution when hoisting cables to lift the unit as the centre of balance is not at the installation centre. • Use expansion bolts to fix the mounting supports on the wall. • Use bolts and nuts to fix the outdoor unit firmly on the supports and keep on the same level. • If the unit is installed on the wall or rooftop, the supports have to be firmly fixed so it can resist strong weather conditions.
INSTALLATION OF OUTDOOR UNIT (Cont.) 1. Check that the pipeline connections have been properly connected. Remove the charging port cap, then connect the manifold gauge and the vacuum pump to the charging valve by the service hoses, (shown in drawing). 2.Open the valve on the low pressure side of the manifold gauge, then run the vacuum pump. Vacuum the indoor unit and the connecting pipes until the pressure in them lowers to below 1.5mmGH (the operation time for this should be about 10 minutes).
INSTALLATION OF OUTDOOR UNIT (Cont.) GAS LEAKAGE INSPECTION After the pipeline connections are done, use a leakage inspection device or soap suds to carefully check if there is any leakage at any joints. This is an important step to ensure the quality of the installation. Once a leakage is detected, proper treatment should be taken immediately.

SUITABLE INSTALLATION POSITION • Is there anything that prevents ventilation, or obstructs operation and effective air flow in front of the indoor unit? • Do not install in locations where flammable gases may leak or oil splashes often. • In seaside districts where sea breezes will be encountered by the unit, the high salt content in the air often leads to early corrosion. Please monitor the unit over time.
