Drainage - Immergas AUDAX PRO 5 Instruction And Recommendation Booklet

3.7 DRAINAGE.

During central heating, ice can deposit on the
outer surface of the coolant-air exchanger. To
prevent these deposits from becoming excessive,
the unit runs defrosting cycles to melt them. The
water resulting from this process is eliminated via
drainage holes to prevent it from re-solidifying
at the bottom of the unit when the outdoor
temperature is quite low.
• If, for whatever reason, this water cannot be
allowed to drain freely, you must:
- Leave a space of at least 50 mm (5 kW version)
and 100 mm (8 / 10 mm version) from the
support surface (Fig. 3-8).
- Insert the drainage fitting in one of the three
drainage holes on the bottom of the unit and
plug the other three with the supplied drain
plugs.
- Connect the drainage fitting to a hose that
conveys the water to the desired location.
- Prevent dust and debris from entering the
drainage hose.

Attention: if the water produced by the unit is
not properly drained, the performance of the
entire system will suffer a negative impact and
the system itself could be damaged.
Warnings.
1 Dig a draining channel all around the base of
the unit that can appropriately drain the water
and condensate produced by the unit.
2 To facilitate drainage, you can install the unit
on a base of cement blocks so that it is at least
150 mm off the ground.
3 The unit must be raised at least 150 mm off the
ground to prevent it from being flooded in the
event of heavy rain.
4 If installed in a snowy area, the unit must be
raised off the ground by at least the height of
the heaviest foreseeable snowfall.
5 If wall-mounted (see figure), it is a good idea to
position a container (not supplied by Immer-
gas) about 150 mm below the bottom of the
unit to collect and drain the condensate that
may drip from the unit.
