General information for the installer
General
The water heater is unscrewed from the pallet and lifted
into position, use the lifting eye on the top if necessary.
Mount the enclosed cover discs before pipe installation.
The cover discs, which have s adhesive backing, should be
mounted at each connection by pressing them over the
connections. All connections (including connections that
are not used) should be isolated to minimize idling losses.
The water heater may only be installed vertically and can
be aligned using the adjustable feet (10).
Once the water heater is in the correct position, remove
the lifting device from the top.
Fit the enclosed insulation plug in the hole left by the
lifting eye (40).
If a secondary return circuit is used, an additional expen-
sion vessel can be required.
Assembly
• The water heater is only designed for upright installa-
tion.
• Position the water heater on a firm base that can bear
• its weight, preferably on a concrete floor or founda-
tion. Use the water heater’s adjustable feet to obtain a
horizontal and stable set-up.
• The water heater’s installation area should always have
a temperature of at least 10 °C (to prevent the risk of
damage from frost) and max 30 °C.
