Before beginning installation, consider the placement of  both the
indoor and outdoor units. It is important to correctly measure the
distance the tubing will need to travel between the two units.

•

Make sure you do not block the discharge area of the outdoor
unit with plants or debris

•  Do not install either unit near any source of heat, steam or

flammable gas

•  Locate the unit in a location where it can be easily maintained

•  Locate the indoor unit in a place where it will provide cool air

throughout the room

•  Locate the indoor unit in a place where the unit’s airflow will

not be obstructed

•

The wall that the indoor unit is mounted to must be
structurally sound and able to support the weight of the unit

•

It is preferable to locate the indoor unit on an outside wall
where there will be access to adequate drainage or a drain
source

•  Place the unit so that the air filter can be removed easily and

maintenance work can be performed without interference

•

Maintain minimum distances from walls, ceiling, and floor
illustrated in figure 3 on page 5 of this manual

Maximum
allowable
tubing length
between indoor
and outdoor
units is 32 feet

Each indoor unit comes with a refrigerant charge that is
sufficient for use with tubing up to 16.4 feet.

If the required length of connecting tubing exceeds 16.4 feet,
add 0.23 oz/ft of refrigerant for each additional foot.

If the outdoor unit is placed higher than the indoor unit, an oil
trap should be installed every 12 feet in the suction line.
