 <HWT-80,110,140>
• As shown in the figure below, install the foundation
and vibration-proof rubber pads to directly support
the bottom surface of the fixing leg that is in contact
with and underneath the bottom plate of the Outdoor
Unit.
* When installing the foundation for an Outdoor Unit
with downward piping, consider the piping work.
■ For reference
If a heating operation is to be continuously performed
for a long time under the condition that the outdoor
temperature is 0 °C or lower, draining defrosted water
may be difficult due to the bottom plate, drain nipple
and drain hose freezing, resulting in trouble with the
cabinet or fan.
It is recommended to procure an anti-freeze heater
locally in order to safely install the air to water heat
pump.
For details, contact the dealer.
