5. Installation of Outdoor Units
5.1 Installating space
Ensure enough space required for installation and maintenance. (Unit: mm)
5.2 Handling and installation
• Because the center of gravity of the unit is not at the center, be careful when lifting the unit with a hoist cable.
• Do not hold the suction port on the casing; otherwise, it will be deformed.
• Do not touch the blades with your hands or other objects.
• Do not tilt the unit over 45° when carrying it; do not store it horizontally.
• Use M8 or M10 bolts to secure the feet of the unit. The unit must be installed firmly to prevent collapse in the
event of an earthquake or a sudden blast.
6. Water discharge piping layout
Note:
Do not exert too much force when installing the suction piping in order not to break the pipes. Wrap both the
suction piping and water discharge piping evenly with heat insulation protective casing to prevent water
condensation.
6.1 Installation of water discharge piping for the indoor unit
• Use the attached water discharge hose to connect to the drainage outlet and PVC piping of the indoor unit.
Use the provided ring clamps to clasp tightly (see Figure 1).
• Use hard PVC adhesives for connecting to other water piping. Check that the connections are tight with no
leakage. Use insulation casing to wrap the water suction piping connections and water discharge piping of the
main body (especially the indoor portion) tie for the water discharge piping to bind them firmly to make sure air
does not enter and condense to form water.
• In order to prevent the back-flow of water into the interior of the air conditioner when the unit stops operating,
the water discharge pipe should slope downwards towards the outside (drainage side) at a slope of more than
1/100. Make sure that the water discharge pipe does not swell or store water, otherwise it will cause abnormal
sounds.
• When connecting the water discharge piping, do not use force to pull and tug the pipes to prevent the main
body from being affected by the force. The distance to pull out the water discharge piping should be within
20m, with supporting points set at every 0.8 to 1.0m to prevent the water discharge piping from bending.
