4.1.1 - Appropriate placement choice
The Pilot must be placed in an area which is free from frost and
adverse weather conditions.
It must be placed as close as possible to the heat pump without
exceeding the maximum distance.
The maximum distance depends on the diameter of piping and the
number of elbows used (see «Hydraulic connection» tables).
The 2-core sheathed cable which connects the Pilot and the heat
pump is 10m long. There is a 20m length available as an optional
extra (Ref. 753102) or 50m (Ref. 754103).
The Pilot must be installed on a level
and stable base which is distanced from
appliances used for cooking and other heat
sources.
The Pilot lled with water can be heavy, watch
over the resistance of the wall stand.
The pilot must be xed on a resistant wall.
4.1.2 - Fixation

- 6P10 PILOT MANUAL -9
4.1.3 - Dimensions
The pilot must be placed at least 200mm above the oor or any
obstacle the enable it to be drained.
It must be placed at least 400mm under the ceiling to facilitate
the access to the air bleed and to the electrical back-up. 4.2.1 - Recommendations
A type CB backflow prevention device may be installed. This
device must be at dierent, non-regulated pressure zones. Check
your national laws and regulations to know if this is an obligatory
requirement. The backflow prevention device is designed to
prevent incoming heating water from entering the drinking water
circuit. It must be connected to the mains drainage system.
4.2.1.1 - Backow prevention device
A sucient ow rate should be ensured so that the dierence in
temperature between the outlet and inlet points does not exceed
6°C. In an installation equipped with thermostatic mixing valves, this
inspection must be done with all taps/valves open.
The output actually needed determines the water ow rate of
the heating circuit and allows to calculate the dimensions of the
distribution network.
Adapt the speed of the circulator pump to the hydraulic
characteristics using the ow rate/pressure curve provided.
All necessary measures must be taken to ensure that the installation
can be continuously purged. 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.
4.2.1.2 - Cross sections, purging of the
heating circuits
4.2 - Hydraulic installation
Consult the hydraulic schematic diagrams in the appendix.
Plan for a desludging tank with a suicient volume at a low point
on the inlet of the heating circuit. This tank must be equipped
with a drain so it can collect the oxides, particles, and calamines
which detach from the inner walls of the heating circuit while it is
in operation.
4.2.1.3 - Desludging tank
Before placing the pilot and heat pump, it is necessary to rinse the
installation with an appropriate product.This allows to eliminate all
traces of soldering waste, joint ller, grease, sludge, metallic particles,
etc... in the radiators, underoor heating, etc...
4.2.1.4 - Preparing the hydraulic circuit
(rinsing)
4.2.1.5 - Insulation of the pipes
Insulators must be in accordance with DTU 67.1.
All the apparent pipes and accessories (circulator, expansion vessel,
valve, ...) must be insulated or placed in insulated box.
4.2.1.6 - Expansion vessel
The installation must be equipped with an expansion vessel with
a sucient capacity (which depends on the static height of the
installation, the blowing-up pressure of the expansion vessel and
the volume of the installation)

- 6P10 PILOT MANUAL -
10
It is IMPERATIVE to refer to the
installation instructions for the initial
installation of the ambient temperature
thermostat to ensure satisfactory operation.
In an installation with both
thermostatic valves and a room
temperature thermostat, the radiator(s) in
the room in which the thermostat is located
MUST be equipped with a manual valve(s).
Thermostatic valves: these valves should prioritise rooms with
higher levels of heat gain.
4.2.1.8 - Thermostatic valves
4.2.1.9 - Treatment of the water in the
heating circuit
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.
Central heating installations must be cleaned
in order to eliminate debris (copper, lings,
soldering waste) related to the set-up of the
installation or from chemical reactions between the
metals.
Futhermore, it is important to protect the
central heating installations from risks of
corrosion, limescale, and microbiological
development through use of a corrosion inhibitor
which is suitable for all kinds of installations (steel or
cast-iron radiators, PEX underoor heating).
PRODUCTS USED FOR HEATING WATER
TREATMENT MUST BE APPROVED BY THE
LOCAL OR NATIONAL PUBLIC HYGIENE
AND HEALTH AUTHORITY.
4.2.1.9.1 - Filling water
The materials used for producing a heating circuit are of dierent
natures. Instances of corrosion may occur through galvanic coupling
in both new and existing installations.
The lling of the heating circuit must only be done with untreated water
(no water softener) from the drinking water network. Water from any other
source )rain-water, well-water, etc...), must be analysed and MUST have
the following properties:
8,5 UPH (acidity) U9,5
Chlorides U60 mg / litre
Conductivity < 1000 μS / cm
5 UTH (hardness in French °) U15
We recommend the use of products in the SENTINEL range by GE
BETZ for preventative and curative treatment of the heating circuit.
• For new installations : (less than 6 months old):
- Clean the installation with a universal cleaner to eliminate
the debris from the installation (copper, bres, soldering
uxes) Example : SENTINEL X300
- Throughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example: SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example :SENTINEL X500.
• For existing installations:
- Desludge the installation with a desludging product
to eliminate any sludge from the installation. Example:
SENTINEL X400.
- Throughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example: SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example : SENTINEL X500.
4.2.1.9.2 - Treatment of the heating circuit
Corrosion inhibitor :
- protects against the formation of limescale
- prevents «pinhole» type corrosion
- prevents, in new installations, the formation of sludge
and the proliferation of bacteria
(in low temperature networks: algae)
- prevents the formation of hydrogen
- eliminates the sound of the generators
Treatment products from other manufacturers can be used if they
guarantee that the product is appropriate for all the materials used

this information refer to their user manual.
Frost protection is necessary if the pilot is switched o during the
winter months (ex: secondary residence, etc...).
4.2.1.7 - Frost protection
If the appliance is connected to an
electricity supply, the heating circuit is
protected from freezing. It is IMPERATIVE
to drain the domestic hot water circuit however.
If the pilot is not being supplied with electricity
(electrical cut-o for example), or it is defective
and there is a risk of freezing, it is IMPERATIVE to
completely drain the appliance (heating and hot
water).

It is mandatory to refer to the technical manual provided with each water tank.
It is mandatory to install a safety group on the cold water inlet of each water tank.
Do not place a stop valve between the safety group and the water tank.
• The number of elbows and pressure losses will have to be minimize, focets will have to be adapted.
• Areas in which domestic water is rich in limestone (HT > 15), we advise the installation of an anti-scale device on the domestic water inlet. The
hydrotimetric title has to be less than 15.
• The concentration in chlorides in DHW has to be less than 60mg/L (required quality for drinkable water intented for human consumption).
Domestic Hot Water can reach more than 60°C, (especially during the anti-legionelosis protection), it is
mandatory to install a thermostatic valve on the DHW outlet to avoid any risk of burn.
4.2.1.10 - Installation of the DHW circuit
4.2.1.11 - Purging the installation
The oxygen present in the air is extremely corrosive. All necessary measures must be taken to ensure that the installation can be continuously
purged. 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.
Any deterioration of the appliance due to inappropriate lling water, and/or corrosion in the absence
oftheuseoftreatmentproducts,and/orimproperpurgingof theinstallation, willrenderthewarranty

RENDERINGTHEWARRANTY NULL AND VOID
The Heat Pump and the Pilot are both equipped with pressure-relief valves. The Pilot’s pressure-relief valve is set at 3 bars.
The pressure-relief valve on the Heat Pump sets the maximum acceptable pressure in the installation (2.5 bars when hot).The maximum service
pressure in the Heat Pump must, consequently, be lower than 2.5 bars.
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 bars.
Therefore it would be advisable to ll the heating circuit at an intermediary pressure (between 1 and 1.5 bars).
For safety reasons (potential presence of ammable R290 gas), drainage of the Pilot’s pressure-relief valve must MANDATORILY be done
outside the building. The outlet of the drainage pipe (4m length provided with the pilot) must be placed downwards in order to avoid any
introduction of water inside, any risk of obstruction due to frozen water or any other pollution (see drawing).
If the provided drainage pipe is too short, it’s mandatory to use a well-adapted length (can by supplied on demand). It will have to be installed
as well as there will be no pinch on it, it will then ensure the drainage of the overpressure from the 3 bar safety valve outside the building.
4.2.1.12 - Connecting the pressure relief valve
ThePilot’spressure-relief valvedrainagepipe
must be properly secured until the outside of
the building without any pinching zone.
WARNING
Failure to comply with this requirement
concerning the evacuation of overpressure outside
the building releases the heat pump manufacturer
from any liability in case of incident.
