After the leak test, apply insulat

ing material tightly so that there
is no gap.
When the piping is to be attached to
a wall containing metals (tin plated)
or metal netting, use a chemically
treated wooden piece 20 mm or
thicker between the wall and the
piping or wrap 7 to 8 turns of insula
-
tion vinyl tape around the piping.
To use existing piping, perform
COOL operation for 30 minutes
and pump down before removing
the old air conditioner. Remake flare
according to the dimension for new
refrigerant.
1-6. DRAIN PIPING FOR OUTDOOR UNIT
1) Perform the drain piping work only when draining from one place.
2) Provide drain piping before indoor and outdoor piping connection.
3) Attach the drain socket to one of the several drain holes.
Fix the drain socket into the drain hole of the base using the catches to secure it
in place.
4) Connect the soft PVC hose I.D.15 mm as shown in the illustration.
5) Make sure to provide drain piping with a downhill grade for easy drain flow.
6) Glue the drain caps to close all the other unnecessary holes with the glue (Prepare
in the field).
Note:
Apply the glue securely, as the glue (Prepare in the field) will work as seal to prevent
water from leaking.
Use the adhesive for the rubber and metal.
Attention
The outdoor unit is provided with several holes for drainage at the bottom to make
drainage easier.
The drain socket is used to close the unnecessary holes and centralize the drainage
when using the drain tube at the installation place.
Do not to use the drain socket in cold region. The drain tube can be frozen.
(1) Drain socket
(2) Drain cap
(L) Soft PVC hose
IMPORTANT NOTES
To comply with the requirements of Australian standard AS/NZS 3000 electrical installations
(wiring rules), the electrical wiring required between the indoor and outdoor units must be
installed by a licenced electrical contractor.
