3. DRAIN PIPE CONNECTION
NOTICE
Be sure to connect the drain hoses properly. Otherwise water leaks from the drain hoses may
damage the surroundings (property).
IMPORTANT
Drain lines shall be as short and straight as possible. The drain hoses shall have an adequate
pitch or fall so that no part is higher than the drain outlets.
To prevent a backflow, do not connect the drain
hoses directly with the sewer system. An air gap of
a minimum of 5 cm should be between the ends of
the drain hoses and the water level of drainage.
When installing more than two units, do not
interconnect their drain hoses. If the interconnection
is necessary, provide an air inlet per unit.
● The drain outlets are at the bottom of the body. Use the accessories to connect the drain hoses.
● HRFE type is provided with two defrost water drain outlets while HRE and HFE types are
provided with only one.
1) Insert the 18 mm diameter end of flexible hose into the
defrost water drain outlet, and fix the flexible hose with
the accessory drain hose band.
2) Attach the other end (26 mm outer diameter) of the
flexible hose to the drainage.
