Technical Installation Instructions and User Guide

GENERAL POINTS
The water heater with smooth-tube heat exchanger can be connected to each gas or oil furnace. The position of the heat exchangers provides
complete heating of the water in the accumulator.
The tank is protected by an enamel covering giving protection up to 850°C, in accordance with the requirements of DIN 4753.
The water heater must be installed by an approved installer, in an area that is protected against freezing. Enamelled tanks are suitable for nor
-
mal domestic hot water and approved for mixed setups (copper tubing, zinc tubing).
Unused connections must be blocked. The directives in force and the instructions from the local water service as well as DIN standards must
be followed.
The tank is linked to the hydraulic distribution network via a cold water connection and to usage points via a hot water connection.
If hot water is taken from a usage point, cold water then enters the reservoir where it is heated to the temperature set using the thermostat
(not provided with the product).
It is advisable to maintain the water temperature between 60° and 65°C, as this guarantees the best performance for the unit and ensures the
following:
- Maximum level of hygiene,
- Maximum limit for thermal loss,
- Limiting the formation of limescale deposits.
INSTALLATION
Installation instructions
ONLY HIGHLY QUALIFIED PERSONNEL ARE AUTHORISED TO PERFORM THIS OPERATION, OTHERWISE THE WARRANTY WILL BECOME
VOID
The information given below determines the validity of the warranty.
1. The installation must:
a. Be installed by a qualied installer. You must conform to current national standards. It is necessary to respect
the instructions for the water heater,
b. Provide, when necessary, a pressure reducer for inlet water,
c. The system is required to have a safety assembly (maximum calibration: 7 bar) which must be installed
with the unit in a location where there is no possibility of freezing.
2. The storage temperature must remain below 90°C.
3. To prevent corrosion, it is necessary to regularly check the charge level of the battery that supplies the protech spark plug and
replace it if there is a fault.
4. In case of installation in a location above a living area (roof space, attics, suspended ceilings, etc.), insulate the pipes and provide
a holding tank with water evacuation. In all cases, a connection to mains drainage is necessary.
Recommended installation space
For maintenance operations to take place, there must be:
- a clear space of at least 50 cm in front of the plastic cover to allow access to the electrical components,
- direct access to the safety assembly,
- particular case of installation in a bathroom
(NF C15 100).
Denition :
Space envelope (A): The space envelope is the space outside the bathtub
or the shower basin, and is limited on one side by the vertical cylindrical
surface around the bathtub or shower basin, and on the other side by the
horizontal plane 2.25 m from the base of the bathtub or shower tray.
Protection space (B): The protection space is the accessibility area for a
person inside the bathtub or the shower basin, which lies outside the spa
-
ce envelope. It is limited by the vertical cylindrical surface 0.60 m from the
base of the bathtub or the shower basin and limited by a horizontal plane
located 2.25 m above the base of the bathtub or shower basin.
This standard is applicable in
France, and of course the installer must re-
main aware of any changes to this standard. For installation in other coun
-
tries, please refer to the applicable local regulations.
Advice :
To prevent overconsumption of energy, it is recommended
that the heater be positioned as closely as possible to the
hot water usage points. (a distance of less than 8 metres is
recommended).
