Connecting The Condensation And Water Drain Pipes; Connecting The Condensation Drain Hose - Panasonic Aquarea WH-ADC0309J3E5 Planning And Installation Manual

6.7.2 Connecting the condensation and water drain pipes

On site, a hose must be connected to the condensation drain of the indoor, outdoor and mono-bloc
units as well as to the water drain of the pressure relief valve. For connection to the condensation
drain, a drain elbow and a packing are provided for each device. The drain hoses and pipes must
be field-supplied.
!
IMPORTANT
When installing the drain hoses, in addition to the safety notes applicable for the entire heating
circuit, pay attention also to the following notes:
● Use commercially available drain hoses with a suitable diameter.

All in One unit J or H Generation
Hydrokit J or H Generation
Hydrokit F Generation
Outdoor unit
Mono-bloc unit
● Install the drain hoses with a constant slope and in such a way that the water outlet
cannot be clogged.
● Install the drain hoses in a frost-free environment.
This is particularly important in the case of outdoor and mono-bloc units, because if
the periods in outside temperatures below 0 °C are long, ground frost can cause the
condensate to form ice. The result can be that the condensate cannot drain off and
this will cause malfunctioning in the heat pump operation.
For safe drainage of condensation water even at outside temperatures below 0 °C, a
drain pipe is recommended, reaching into the frost-free area of the underground.
● Do not conduct the drain hoses into a sewage or cleaning connection from which
ammoniac, sulphurous gases or the like can rise.

6.7.2.1 Connecting the condensation drain hose

Indoor units
Carry out the following steps to connect the drain hose to the condensation drain outlet of the
indoor unit:
1. Assemble the supplied drain elbow with packing on the condensation drain outlet on the
underside of the indoor unit, as shown in the illustrations below.
2. Slide the hose onto the drain elbow.
3. Ensure that the drain hose is seated firmly. Use a hose clip to attach the hose, if necessary
(to be field-supplied).
4. Lay the drain hose with a constant slope into a suitable receptacle for the condensed water
(to be field-supplied).
