A3 - Frost protection
A2 - EU declaration
This device complies with international electrical safety standards
IEC 60335-1, IEC 60335-2-40. The CE marking present on the
device attests to its conformity with the following Community
Directives, of which it meets the essential requirements:
• Low Voltage Directive (LV): 2014/35/EU.
• Electromagnetic Compatibility Directive: (EMC): 2014/30/EU.
• Ecoconception Directive for Energy-related products:
2009/125/EC.
• Limiting Hazardous Substances (ROHS): 2011/65/EU.
In cases where the HRC
70
Heat Pump cannot operate (exterior
temperature is outside of the operating range), and a back-up is
authorised (boiler or electrical), it will automatically be protected
from frost or ice as the circulator pump will operate and draw heat
from the heating circuit which has its temperature maintained by
the HRC
70
Pilot’s electrical back-up or back-up boiler.
The water temperature remains over 5°C.
In all cases the piping must be properly insulated.
Underground piping should be installed within protective
guttering.
However, in the case of installation without a back-up, or if the
HRC
70
Pilot or HRC
70
Heat Pump is being switched off during the
winter months (ex. accidental stop, secondary residence, etc...), an
additional anti-freeze protection is necessary.
Apply glycol to the heating circuit (with a minimum concentration
of 25% glycol) or make sure to have hydraulic circuit draining
measures in place for the HRC
70
Heat Pump and its accessories
(described below).
Choose the % of glycol based on the minimum exterior
temperature to protect the water circuit from freezing (the
concentration should not be under 25%) :
Do not use mono-ethylene glycol
(toxic product)
When using a concentrated protect which
needs to be diluted with water, mix the
water+anti-inhibitor mixture
together prior to inserting it into the installation.
RENDERING THE WARRANTY NULL AND VOID
All deterioration of the appliance due to
an inappropriate quality of water and/
or the presence of corrosion in the
absence of
treatment products as described above, and/
or an improper purging of air of the installation
will render the warranty to be null and void.

Regularly check the pH level and % of
glycol in the installation.
•Never top-up the glycol in your installation
without measuring the pH to check that the
drop in glycol % is not due to a deterioration of
the glycol.
•When the pH is acidic (<7) replace all of the
glycol after having already drained and rinsed
the installation.
A4 - Treatment of the water in the
heating circuit
A4.1 - Preparing the hydraulic circuit
(rinsing)
Before installing the Pilot and the HTi
Heat Pump, it is necessary to
rinse the installation with an appropriate product.
This permits the elimination of all traces left from soldering,
solder
ing fl uxes, grout, grease, sludge, metallic particles, etc..in
radiators, underfl oor heating, etc...
This prevents any of the abovementioned waste from getting into
the HTi Heat Pump heat exchanger, or from obstructing the fi lter
installed on the incoming water inlet.
A4.2 - Filling water
The materials used for producing a heating circuit are of diff erent
natures. Instances of corrosion may occur through galvanic coupling
in both new and existing installations.
The fi lling of the heating circuit must be done only with untreated water
(no water softener) from the drinking water network.
Filling with
water from any other source (well water, rain water etc...)
will render the warranty null and void.
A4.3 - Treatment of the heating circuit
Central heating installations must be
cleaned in order to eliminate debris (copper,
fi 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 underfl oor heating).
PRODUCTS USED FORTHE TREATMENT
OF HEATING WATER MUST BE
APPROVED BY THE LOCAL OR NATIONAL
PUBLIC HYGIENE AND HEALTH AUTHORITY.
We recommend the use of products in the SENTINEL range 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, fi bres, soldering
fl uxes) Example : SENTINEL X300 or SENTINEL X800.
- Throughly rinse the installation until the water runs clear,
with no traces of impurities left.
It is MANDATORY to read the additional
document concerning the quality of
water used for fi 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.
