Installation Procedure
Installation Procedure
Step 11 Connecting the drain hose to
the outdoor unit
• When using the air conditioner in the heating mode,
ice may accumulate . During de-icing (defrost
operation), the condensed water must be drained off
safely. Consequently, you must install a drain hose on
the outdoor unit, following the instructions below.
1 Make space more than 80 mm between the bottom of
the outdoor unit and the ground for installation of the
drain hose, as shown in figure.
2 Insert the drain plug into the hole on the underside of
the outdoor unit.
3 Connect the drain hose to the drain plug.
4 Ensure that the drained water runs off correctly and
safely.
0.51inch (13mm)
3.15inch (80mm)
5 Be sure to plug the rest of drain holes not connected
with drain plugs using drain caps.
Drain cap (3EA)
Drain plug (1EA)
• When installing the product, make sure that the
rack is not placed under the drain hole.
• If the product is installed in a region of heavy
snow, allow enough separation distance between
the product and the ground.
CAUTION
• For AC018/024BXADCH model, do not install a drain
hose and a drain plug, drain cap.
(Let the water drain naturally.)
• Ice may form on the ground. Take appropriate
measures to prevent ice formation.
<Applicable model : AC018/024BXADCH>
Step 12 Insulating the refrigerant
pipes
1 Once you have checked that there are no leaks in the
system, you can insulate the piping and hose.
No gap
NBR
NOTE
• When insulate the pipe, be sure to overlap the
insulation.
• The insulation has to be produced in full compliance
of European regulation reg. EEC / EU 2037/ 2000
that requires the use of sheaths insulation form
without using CFC and HCFC gases for health and the
environment.
CAUTION
• When insulating the pipe, use non-slit insulator.
