• In case of draining through the drain hose, attach the
following drain nipple and the waterproof rubber cap,
and use the drain hose (Inner diam.: 16 mm) sold on
the market. And also seal the screws securely with
silicone material, etc. so that water does not drop
down. Some conditions may cause dewing or
dripping of water.
• When collectively draining discharged water
completely, a drain pan must be made locally.
For Reference
If a heating operation would be continuously performed
for a long time under the condition that the outdoor
temperature is 0 °C or lower, draining of defrosted
water may be difficult due to freezing of the bottom
plate, resulting in a trouble of the cabinet or fan.
It is recommended to procure an anti-freeze heater
locally for a safety installation of the Air to Water Heat
Pump.
For details, contact the dealer.
