2.1 - Standard conguration
2 - INTRODUCTION
The ensemble is composed of an exterior unit (Mono-block high temperature Heat Pump to be installed outdoors exclusively) and of an
interior unit (Pilot, to be installed indoors exclusively) connected together through a hydraulic connection and a communication bus.
The air to water Heat Pump, draws calories from the exterior air and transfers them to the heating water circuit with high energy eciency.
The Pilot ensures the regulation and hydraulic distribution of the installation.
A circulator is built into the heat pump. It supplies water ow from the heat pump to the pilot.
The cylinder built into the pilot provides hydraulic decoupling between the heat pump and the heating circuit(s).
The Pilot is delivered pre-congured for the heating of a radiator circuit controlled by a room temperature thermostat from the Heat Pump alone.
In the case of connection to a back-up boiler, it is used to load the decoupling tank directly.
Nota :
The heat pump is designed to operate in heating mode. Operation in cooling mode is possible subject to compatibility with the pilot and the
heat emitters.
2.2 - Operation
The Heat Pump is a closed and pressurised system in which the
refrigerant serves as the medium for transferring energy.
A safety pressure switch is used on the refrigeration circuit, it is
located on the high pressure part of the circuit at the output of the
compressors. It is a dry contact that when the pressure becomes
too high (>31 bar) opens. Once opened, it cuts the power to the
compressors, independently of the electronics and thus protects
all circuit components.
The evaporator () is a cooling exchanger which draws calories
from the air.
The humidity in the air condenses on contact with the cold surface,
and forms condensation (evacuation in ()).
The condenser (), a plated ehat exchanger which is hydraulically
linked to the heating installation (), via the Pilot, enables to heat
the water in the heating circuit, and in turn enables the heating of
the building.

3.1.3 - Noise levels
The Heat Pump is equipped with a large diameter fan so as to allow for an appropriate air ow rate. This ow rate can rise up to 12000m3/h for
the HRC70 40kW heat pump and the double that for the HRC70 80kW heat pump. The fan speed is adjustable to limit the noise level.
Depending on the installation conditions, the noise levels may be dierent, in particular if the walls closest to the Heat Pump cause a reverberation
and amplication of noise.
The diagrams below show dierent installation examples for dierent placements.

- INSTALLER HRC70 40KW60KW80KW TRI V HEAT PUMPS MANUAL - 17
3.2.1 - Hydraulic connections on the installation
In order to ensure that uids 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 HRC70 40/60/80kW Heat Pump is intended for with a large variety
of heating installations due to its power level.
The circulator(s) included in the heat pump provide the ow rate
required to transmit power to the pilot.
The connection between the heat pump and the pilot must be
sized to ensure the correct ow rate between these two elements.
3.2 - Hydraulic installation
It is MANDATORY to read the additional
document concerning the quality of
water used for lling the installation.This
document is included with this manual as well as
in the packet with the warranty information.
This document also contains information which is
PERTINENT to the WARRANTY of the material.
3.2.3 - Pressure-relief valves
The Heat Pump and the Pilot are both equipped with pressure-
relief valves.
The pressure-relief valve on the Heat Pump sets the maximum
acceptable pressure in the installation (3 bar when hot). The
maximum service pressure on the Heat Pump must, consequently
be lower than 3 bar.
Example : If the Heat Pump is positioned 5m below the Pilot, the
pressure reading on the Pilot would be 0.5 bars less than the
real pressure of the water in the Heat Pump. In this case, the
maximum service pressure for the Pilot would be 2,5 bar.
Therefore it would be advisable to ll the heating circuit at
an intermediary pressure (between 2 and 2.5 bar).
In case of operating with a back-up boiler, these pressure-relief
valves MUST be installed in addition to the ones which the boiler
is already equipped with (set at 3 bar).
The connections and the evacuation conduits for the pressure-relief
valves must be made from materials which are resistant to high
temperatures and corrosion.
3.2.2 - Sizing of the Heat Pump circuit
A sucient ow rate must be ensured so that the temperature
dierence between the ow and return of the heat pump does not
exceed 8°C during operation (carry out a test measurement when the
HRC70 heat pump is in heating mode and the operating mode is set):
The hydraulic cross-section of the connection between the heat
pump and the decoupling cylinder must be sucient. For this, refer
to the pilot part supplied with the heat pump.

Nota :
Condensate must not run o into passageways (risk of freezing).
3.1.4 - Condensates drainage
The condensate drain for the HRC70 40kW-60kW-80kW is located
under the heat pump. A G1’’F connection is located in the centre of
the condensate tray. Condensate can drain freely or be connected
to a draining surface. In the latter case, ensure that the drain is kept
frost-free (optional defrosting cord - Ref. 751004).

3.2.5 - Back-ow prevention device
French law (articles 16.7 and 16.8 of the ‘‘Règlement Sanitaire
Départemental’’) stipulates that a type CA back-ow prevention
device must be installed. This device must be at dierent, non-
regulated pressure zones, in accordance with the NF EN 14367
standard. This is also an obligatory requirement in other countries,
which makes it important to verify the current laws and standards in
eect in the country of installation and ensure that your installation
is in compliance with them. The back-ow prevention device is
designed to prevent incoming heating water from entering the
drinking water circuit. It must be connected to the mains drainage
system.
3.2.6 - Purging the heating circuit(s)
All necessary measures must be taken to ensure that the installation
can be continuously degassed. Automatic air purging valves should
be placed at each high point of the installation, and manual air
purging valves should be installed on each radiator.
3.2.8 - Expansion vessel
An expansion vessel needs to be installed onto the heating circuit.
See Appendix A6 for information on proper sizing of the expansion
vessel.
3.2.9 - Frost protection and water treatment
See the recommendation in Annexes A4 and A5.
3.2.4 - Heat Pump water inlet lter (supplied)
A 500μm sieve lter (or two for HRC70 60 and 80kW tri V) is installed
in the heat pump.
• Do not change the connection direction.
• Observe the direction of ow of the lter (arrow).
• Clean the lter at least once a year (do not use tools that
could damage the sieve).
Before installing the heat pump, the system
must be de-silted and ushed.
Clean the lter several times when starting
up the heat pump circulators (take care to
stop the heat pump circulator when cleaning).
3.2.7 - Insulating the piping
Insulations must conform to the DTU 65.20 and the DTU 67.1
standard, or the current regulations in eect in the country of
installation.
All visible piping and accessories (circulator pump, expansion vessel,
valves, etc...) must be either insulated or placed in insulated sleeves.
Remember to insulate the distribution manifolds and the inlet and
outlet ow pipes to the underoor heating circuit.
Remember to insulate the piping which connects the Heat Pump
to the Pilot.

- INSTALLER HRC70 40KW60KW80KW TRI V HEAT PUMPS MANUAL - 19
The rules and regulations in the country of installation MUST be respected (standard C15-100).
•The electrical lines for general power supply to the circuits must be made in compliance with your country’s
current rules and regulations (standard C15-100).
• Standard C15-100 determines the cable section to be used based on acceptable currents.
• Standard C15-100 determines the cable section to be used based on the following elements :
- Nature of the conductor :
. type of insulation, number of strands, etc...
- Installation mode :
. inuence of conductor and cable groups
. ambient temperature
. tightly or non-tightly installed
. length of cables, etc...
3.4 - Connecting to the power supply
Ensure that the power supply is sucient to supply both the Heat Pump and the electrical back-up if necessary, taking into account any other
domestic usage of electricity.
Connection to the power supply for each appliance must be done by a qualied professional with the mains power switched o.
3.3 - Electrical control connections
The Heat Pump is pre-equipped with a non-polarised, 2-core sheathed cable (communication bus). This 10m cable is supplied with, and
already connected to, the Heat Pump. It must be connected to the Pilot.
If the connection needed is longer than 10m replace this cable with a 20m cable which is available to order (Ref.753102).
If the connection needed is longer than 20m replace this cable with a 50m cable which is available to order (Ref.754103).
• Cut the bus link to the right length : LOOPS ARE FORBIDDEN.
A : Marron / Brown
GND : Noir / Black
B : Blanc / White
For heat pumps supplied with a ZéPAC pilot, a 50 metre bus cable is supplied with the pilot.
It is MANDATORY to connect the
shielding of the connection cable
on the terminal block «GND».

by the manufacturer’s warranty.
ELECTRICAL INSTALLATION
RECOMMENDATIONS
3.4.1 - Proximity switch
The HRC70 40/60/80kW heat pump is fitted with a proximity
switch. The heat pump is supplied with electricity by connecting
the four conductors to the switch (three phases + neutral).
The stripping length (or crimped end length) for this connection
is 12mm. Use a 6.5mm slotted screwdriver or Pozidriv 2. Each
conductor should be tightened to 4.5N.m. Once the conductors have
been connected, be sure to replace the terminal covers supplied.
• During transport, the electrical connections
may be subject to accidental loosening.
• To eliminate any risk of abnormal heating, it is
necessary to ensure the placement of the faston
type electrical connections are secure and tighten
the screw connections.
See § «Spare parts - electrical boxes»
Each appliance is delivered from the factory completely pre-wired.
However, it is necessary to connect the following elements to the
relevant terminals:
• The electrical supply of the power circuit for each appliance
separately : the Heat Pump.
• The 2-core sheathed (+ ground) connecting cable (10m length
supplied) between the Heat Pump and the Pilot.
Under no circumstances will the manufacturer be held liable for any
problems which may arise due to improper installation, choice of
power supply cable, or measures used for installation.
