Drain installation
31 21
CAUTION
Perform drain work in accordance with this
•
Manual, and ensure that the drain water
is properly drained. If the drain work is not
carried out correctly, water may drip down
from the unit, wetting the furniture.
When the outdoor temperature is 32 ° F (0 ° C)
•
or less, do not use the accessory drain pipe and
drain cap. If the drain pipe and drain cap are
used, the drain water in the pipe may freeze in
extremely cold weather. (Reverse cycle model
only).
As the drain water flows out of the outdoor
•
unit during heating operation, install the drain
pipe and connect it to a commercial 16mm
(5/8in.) hose. (Reverse cycle model only)
When installing the drain pipe, plug all the
•
holes other than the drain pipe mounting hole
in the bottom of the outdoor unit with putty
so there is no water leakage. (Reverse cycle
model only)

CAUTION
The installation space shown in the following examples is based on an ambient temperature under cooling operation
•
of 35 °C (DB)(95°F DB) at the air intake of the outdoor unit. Provide more space around the air intake than shown in
the examples if the ambient temperature exceeds 35 °C (DB)(95°F DB) or if the thermal load of all of the outdoor units
exceeds the capacity.
Consider the transportation route, installation space, maintenance space, and access, and install the unit in a
•
location with sufficient space for the refrigerant piping.
Observ
•
e the installation space specifications that are shown in the
figures.
Provide the same space for the air intake at the rear of the outdoor
unit.
If the installation is not performed according to the specifications,
it could cause a short circuit and result in a lack of operating
performance. As a result, the outdoor unit might easily be stopped
by high-pressure protection.
