When the appliance is operating in frost protection mode,
the condensed water must be drained off. In order for the
condensates to drain properly, the drainage trough and hole must
be clean and free of all debris (leaves, grass, etc...).
If the condensates drainage pipe is connected to the rainwater
run-off system, it is advised to use a siphon.
Do not use any tools to remove ice (risk of damage to the heat
exchanger).
The Heat Pump is delivered with a flexible and transparent
condensates drainage pipe (Ø20/25mm) which does not drain
outdoors.
Before activation of the appliance, it is mandatory to connect this
flexible pipe to one of the two holes provided for this purpose:
- Remove the back panel of the appliance.
- Position the flexible hose in its chosen place after
having drilled a hole in the grommet.
a - Draining from underneath
the Heat Pump
This solution is recommended to minimise the risk of ice at the
condensates drainage point.
b - Draining from the back
of the Heat Pump
Is an acceptable solution but in this case an external heater
cable (Ref. 751004) needs to be connected. Please refer to §
«Heater cable for external condensates drainage» as well as
the instructions provided with the heater cable itself.

3.2 - Hydraulic installation
In order to ensure that fluids can circulate properly, it is advisable
to check that the sizing of piping in the circuit is appropriate
between the Heat Pump and the Pilot.
The HRC
70
35 Heat Pump is intended for with a large variety of
heating installations due to its power level.
The circulator(s) supplying the heating circuit(s) are not delivered
with the hydraulic pilot. It is necessary to properly size and select
the appropriate circulator(s) for each installation.
The hydraulic pilot ensures the circulation of water in the Heat
Pump. It must be installed between the Heat Pump and the
decoupling bottle according to the connection diagrams in the
hydraulic pilot manual.

3.2.2 - Sizing of the Heat Pump circuit
A sufficient flow rate must be ensured so that the difference in
temperature between the outlet and inlet of the Heat Pump is not
more than 5°C with a single compressor in operation (avec un seul
compresseur en fonctionnement (take a temperature measure
when the HRC
70
Heat Pump is in heating mode and the system is
fully functioning) :
The hydraulic connection section between the Heat Pump and
the Pilot must be sufficient.
Using the table on the following page, determine the minimum
inner diameter of the connection of piping needed depending on
the distance* which separates the Heat Pump and the Pilot:
