Space Reservation
To facilitate maintenance and operation, and to promote air flow circulation, leave clearance
in the equipment's surroundings.
1. To ensure normal operation of the indoor unit, whenever possible, select a spacious
room to install the indoor unit in. It is advised to leave at least 2.5 feet on the rear where
the door opens to facilitate wiring and piping, as is shown in
Figure 3-1
.
If lower piping is adopted, the height of the elevation stand may not be less than 2 feet.
2. Avoid placing the indoor unit in a narrow place; otherwise, it will obstruct air flow and
shorten the cooling cycle, resulting in air return short circuit and air noise.
3. Avoid placing the indoor unit in a dead end or at the end of a narrow and long space.
4. To facilitate daily care and maintenance, do not install other equipment in the airway
above the air handling unit.
