NOTE
• If R-410A refrigerant is charged with gas, the
composition of the charged refrigerant changes and
the characteristics of the equipment vary.
• While adding refrigerant use an electronic scale to
measure the volume added. If the refrigerant cylinder
doesn’t have a siphon, turn it upside-down.
Step 10 Connecting the drain hose to
the outdoor unit
When heating, ice may accumulate. During the process of
defrosting, check if condensation draining is adequate.
For adequate draining, do the following :
(For AJ***CXS*CH model, do not install a drain hose and
a drain plug, drain caps.)
1
Insert the drain plug into the drain hole on the
underside of the outdoor unit.
2
Connect the drain hose to the drain plug.
3
Ensure that condensation draining is adequate.
4
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 AJ***CXS*CH model, do not install a drain hose
and a drain plug.
‐
Let the water drain naturally.
• Ice may form on the ground. Take appropriate
measures to prevent ice formation.
<Applicable model: AJ***CXS*CH>
Step 11 Checking the earthing
If the power distribution circuit does not have a earthing
or the earthing does not comply with specifications, an
earthing electrode must be installed. The corresponding
accessories are not supplied with the air conditioner.
1
Select an earthing electrode that complies with the
specifications given in the illustration.
2
Connect the flexible hose to the flexible hose port.
• In damp hard soil rather than loose sandy or gravel
soil that has a higher earthing resistance.
• Away from underground structures or facilities,
such as gas pipes, water pipes, telephone lines and
underground cables.
• At least 6.56 ft (2 m) away from a lightening
conductor earthing electrode and its cable.
NOTE
• The earthing wire for the telephone line cannot be
used to ground the air conditioner.
