How to Install the Unit
1. To prevent vibration and noise, make sure the unit is
installed securely and firmly
2. Install the unit where the sunlight does not shine
directly on the unit.
3. The outside of the cabinet must extend outward for at
least 14" and there should be no obstacles, such as a
fence or wall, within 20" from the back of the cabinet
because it will prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling
efficiency of the air conditioner.
All side louvers of the cabinet must remain
exposed to the outside of the structure.
4. Install the unit at a slight incline so the back is slightly
lower than the front(about 1/4").
This will force condensed water to flow to the outside.
5. Install the unit with the bottom about 30"~60" above
the floor level.
