3. INSTALLING THE EQUIPMENT
• The lifting ring on the upper part of the tanks can be used to position them with a
hoist.
• Place the tank and its safety unit (and/or safety valve)
in a frost-free place.
• Position it as near as possible to the most-used taps.
• If it is placed outside occupied areas, insulate the pipework. If the device needs
to be installed in a location where the ambient temperature is always above 35°C,
ensure the space is ventilated.
• Ensure that the supporting structure is strong enough to take the weight of the tank
when it is filled with water.
• Allow a minimum of 1 metre in front of the flange (or manhole) for regular maintenance
of the tank.
• Fit a retention tank with a drain beneath the tank if it is located in a loft or above premises
in use.
• The safety unit and/or safety valve must be accessible.
• A drain connection must be provided equipped with a funnel.
• The lower tapping allows the tank to be drained fully.
• The tank only operates in the vertical position.
• Any unused couplings must be suitably sealed.
The water tightness of the complete system must be checked under normal operating
conditions and during maintenance operations, and the flange couplings must be tightened,
if necessary.
The hot water tank must be included in the potential equalisation.
For safety reasons, water may flow out of the evacuation duct when the tank is heating
up. Do not close or obstruct the evacuation duct.
4. FITTING THE MAGNESIUM PROTECTION
The magnesium protection is assembled in factory but the sealing must be done on site .
See chapter 8 for maintenance.
5. HYDRAULIC CONNECTION
Before proceeding with the hydraulic connection, the supply pipes must be thoroughly
cleaned to avoid introducing metal or other particles into the tank.
If metal pipes are used, the connection to the hot water outlet must use a dielectric pipe
joint or cast-iron sleeve to prevent galvanic corrosion (iron-copper). Brass connections
are prohibited here. A certified safety unit or non-return flap and safety valve assembly is
obligatory.
If the network supply pressure is ≥ 5 bar, a pressure reducer must be fitted to the distribution
outlet. A pressure of 3 to 4 bar is recommended. Check that the pressure does not exceed
the service pressure in operation.
Fit a bleed outlet to the tank´s top connection (DHW outlet).
To avoid clogging the installation´s components (heat exchangers, safety valve, safety unit)
