Condenser Installation Manual

CAUTION
• Do not install the outdoor unit in two-stage where the drain water
could freeze. Otherwise the drainage from the upper unit may form
ice and cause a malfunction of the lower unit.
• In the area with heavy snowfall, if the intake and outlet of outdoor unit
is blocked with snow, it might become di󰀩cult to get warm and it is
likely to cause of the breakdown. Please construct a canopy or ba󰀪e
board (local congured).
• If the unit is installed in a region that is exposed to high winds,
freezing conditions, freezing rain, snow fall or heavy snow
accumulation, take appropriate measures to protect it from those
elements.
To ensure stable operation, the outdoor unit must be installed on a
raised stand or rack, at or above the anticipated snow depth for the
region.
The installation of snow hoods and drift prevention fencing is
recommended when blowing and drifting snow is common to the
region.

3.4. Drain installation
CAUTION
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 extreme cold weather. (Reverse cycle model only)
• Since the drain water ows out of the
outdoor unit during heating operation,
install the drain pipe and connect it to a
commercial 5/8 in (16 mm) hose.
• 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.

Do not install the outdoor unit in two-stage where the drain water could freeze.
Otherwise the drainage from the upper unit may form ice and cause a malfunction of
the lower unit.
NOTES:
• If the space is larger than stated above, the condition will be the same as when there is
no obstacle.
• When installing the outdoor unit, be sure to open the front and left side to obtain better
operation e󰀩ciency.
3.3. Mounting the unit
• Install 4 anchor bolts at the locations indicated with arrows in the gure.
• To reduce vibration, do not install the unit directly on the ground. Install it on a secure
base (such as concrete blocks).
• Depending on the installation conditions, the outdoor unit may spread its vibration
during operation, which may cause noise and vibration. Therefore, attach damping
materials (such as damping pads) to the outdoor unit during installation.
• Install the foundation, making sure that there is enough space for installing the
connection pipes.
• Secure the unit to a solid block using foundation bolts. (Use 4 sets of commercially
available M10 bolts, nuts, and washers.)
• The bolts should protrude 1 in (20 mm). (Refer to the gure.)
• If overturning prevention is required, purchase the necessary commercially available
items.
• The foundation shall support the legs of the unit and have a width of 2 in (50 mm) or
more.
