Product information/unwrapping
Aquarea Delta is a stainless steel indirect water heater.
The product is designed for heating domestic hot water
from an external heat source such as heat pump, solar
panel, gas boiler, biomass etc. Technical data, see table
below.
Unwrap the product carefully to avoid cosmetic damage.
Install the product on a flat, even surface designed to carry the
full weight of the product when filled with water. Adjust the
factory fitted adjustable feet as needed. The product must be
installed in an upright, level position. All piping and electrical
work must be performed by an authorized installer.
Before filling unit with water it is recommended to fit the
electric power cable, see 'Electrical installation' on next page.
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 l. and larger must
be securely fastened to the wall.
The appliance can be positioned with minimal clearance from
walls, but it is recommended to leave at least 800 mm. service
space in front of the electric central and 300 mm. clearance
above unit top.
This appliance is intended to be permanently connected to
the main water supply.
All units are CE approved. Only safety valve approved to NBI

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 instal-
lation/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 central.
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 thermostat
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 element. 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 element. Fill unit
completely with water and make sure the element is not leak-
ing. Fit wire to element. Install thermostat by pressing firmly.
Fit the electric wires to thermostat. Tighten all wire connec-
tions 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.
