Important: Fill unit with water before turning power on.
Failure to comply will terminate guarantee.
On tilted floors the appliance must be installed upright and
level by adjusting the built-in feet. Units 250 I. and larger
must be securely fastened to the wall.
This appliance is intended to be permanently connected to
the main water supply.

Electrical installation

All electrical installation and service must be performed by
authorized electrician. Thermostat is connected as shown.
Ground wire connects directly onto heating element.
The power supply cable is led into the electric central from
below. The cable can be fitted in the desired cable slot in
the unit base by turning the water heater on its back before
installation/filling.
DO NOT turn power on before unit is filled with water. Failure
to comply will terminate guarantee.
When heating the unit with an external heat source (gas boil-
er/heat pump/solar panels) the system must be secured with
a suitable thermostat to ensure the water heater thermal cut­
off does not operate.
Note: The power cable must be fitted with an appropriate
strain relief at the point where it is fed into the electric cen­
tral.
The Delta series is approved to IP 21.
Disconnecting the appliance from the main power grid must
be done with electric fuse or an appropriate switch.
Replacing the thermostat/element:
Turn off power supply and remove electric central cover.
Turn off water supply and drain unit. Unscrew wires on ther­
mostat and element. If only the thermostat is being replaced
the wire on the element can be left on. The thermostat is
removed by pulling it straight out from its sockets on the ele­
ment. The element can then be removed/replaced by using
an element tool, see 'Spare parts'. Ensure the o-ring seal on
the element is in place and undamaged before fitting the el­
ement. Fill unit completely with water and make sure the ele­
ment is not leaking. Fit wire to element. Install thermostat by
pressing firmly. Fit the electric wires to thermostat. Tighten
all wire connections thoroughly. Re-tighten after 3 months.
The electric central cover must be re-fitted and the unit must
be filled with water before power is turned on.
