Installation notes
!Please note
To prevent material losses,
install the DHW cylinder in a
room free from the risk of frost
and draughts.
Alternatively, drain it when not
in use and there is a risk of
frost.
&Allow an adequate distance to the
wall to enable the thermostat (if
installed) to be operated.
&750 and 1000 litres capacity:
Allow a sufficient distance for the
replacement of the magnesium
anodes.
&Level the DHW cylinder with its
adjustable feet.
Note
Never extend the adjustable feet
beyond a total length of 35 mm.
Installing an electric immersion heater in DHW cylinders from 300 litres
capacity
Installation instructions –EHO
electric immersion heater
Maintain the minimum clearance.
Note
The unheated length of any threaded
immersion heater installed on site
must be at least 100 mm.
The threaded immersion heater must
be suitable for installation in enamel-
coated DHW cylinders.
