Thermostatic Mixing Valves Equipping The Water Loops Of The; Underfl Oor Heating Circuit; Underfl Oor Heating Circuit Circulator; Treatment Of The Water In The Heating Circuit - Dimplex Edel 200 WATER/3 Installation Manual

5.2.6 - Thermostatic mixing valves equipping
the water loops of the underfl oor heating
circuit
If there are thermostatically controlled valves equipping the
recirculating pumps for the underfloor heating circuit on the
appliance, (rep.18), leave them permanently open (by manually
opening them or by disassembling the thermostatic head).
The permanently irrigated flooring should have the minimum
surface area necessary for the capacity of the appliance.
This is to avoid damaging the circulator equipping the heat pump
water heater and limits the running of the electrical back-up instead
of the heat pump.

5.2.7 - Underfl oor heating circuit circulator

To help the circulator equipping the heat pump water heater if it is
distanced from the derivation module (long distance or the diameter
of connection is too weak), let the underfl oor heating circuit circulator
(rep.17) run permanently, summer and winter.
This allows to limit operation of the appliance using the electrical
back-up instead of the heat pump.
5.2.8 - Treatment of the water in the heating
circuit
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.
If the domestic hot water heat pump is connected to an installation
with existing underfl oor heating, it is necessary to thoroughly rinse
and treat the installation.

5.2.9 - Filling water

The materials used for the production of a heating circuit have
diff ering properties. These properties can create a phenomena
of corrosion through the creation of a galvanic bridge in new
installations as well as in older ones.
The fi lling of the water circuit must be done only with water from
the domestic water network using untreated water (no softener).
Using water from any other source (well water, rain water, etc..) will
render the warranty null and void.

5.2.10 - Treatment of the heating circuit

Central heating systems MUST BE
CLEANED to eliminate debris (copper,
fi bres, soldering fl uxes) related to set-
up and installation, as well as to avoid chemical
reactions between the metals.
It is also important to TO PROTECT THE
CENTRAL HEATING SYSTEM AGAINST RISKS
OF: CORROSION, LIMESCALE, AND MICROBIAL
DEVELOPMENT by using an APPROPRIATE
corrosion inhibitor for all types of installations
(steel or cast-iron radiators, underfl oor heating).
PRODUCTS USED FOR THE TREATMENT OF
HEATING WATER USED MUST COMPLY WITH
ALL NATIONAL STANDARDS IN THE COUNTRY
OF INSTALLATION.
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.
- Thoroughly 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 or SENTINEL R600.
• For existing installations:
- Desludge the installation with a desludging product
to eliminate any sludge from the installation. Example:
SENTINEL X400 or SENTINEL X800.
- Thoroughly 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 or SENTINEL R600.
Corrosion inhibitor:
- protects against the formation of limescale
- prevents «pinhole» type corrosion

(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
in the appliance and off ers effi cient resistance to corrosion. To fi nd
this information refer to their user manual.
