Product information/unwrapping
Electrical installation
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
06870/387 is allowed for use with this product. All electrical
equipment is approved to LVD 2006/95EC (directive for low
voltage systems) and EMC 2004/108 EC (electromagnetic
compatibility).
Pipe fitting, see next page.
Guarantee, see page 6.

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.
Temperature
sensor is
tted inside
the electric
central,
ensuring it
is in direct
contact with
the stainless
steel vessel.

Pipe fitting:
The piping must be fitted in accordance with the current
regulations in the area where the product is installed. All
pipe fitting must be performed by an authorized installer.
Pipe connections:
CW inlet: 3/4” BSP female
HW outlet: 3/4” BSP female
HW circulation: 3/4” BSP female
Coil flow/ret: 3/4” BSP female
T&P valve connection: 1/2” BSP female
Connection heights and dimensions, see next page.
It is recommended to install the product in a frost free
environment. The product must be installed in a room fitted
with a gulley. If this is not possible an overflow pipe (min.
ø18 mm internal) must be fitted to the P&T/safety valve. The
pipe must be installed uninterruptable and safe from frost,
sloping to a dimensioned gulley/drain.
The G3 valve kit is connected to the unit as shown in the
illustration.
Filling the unit
The unit MUST be filled with water before electric power
supply is turned on. Open main water supply. Drain air from
vessel through nearby hot water faucet until water flows
evenly. Close faucet.
Coil is filled when installing external heat source. Follow
instructions supplied with external heat source or contact
approved installer.
Draining
Turn off power supply. Turn off water supply. Drain unit by
disconnecting cold water inlet pipe. Open a nearby hot water
faucet to release vaccuum.
Draining the coil: See instructions supplied with external
heat source. Disconnect return pipe to empty coil.
Annual check-up
Perform first time after approx. 3 months in service, then
annually.
Check all pipe fittings for leaks. The function of the safety
valve must be tested by opening the valve and observing
that water flows freely. Close the valve after testing.
Check electrical connections for any damage. The internal
electric central is inspected by turning off the power supply,
then removing the el. box cover. Ensure that all internal
wiring and components are intact and working. Tighten wire
connection points. Fit the el. box cover before turning power
supply back on. If needed contact authorized personnel.
Service, maintenance and inspection
The manufacturer recommends that maintenance and
servicing of the unit is performed by authorized personnel in
accordance with the information in this manual.
The 5/4” element connection can be used for internal
inspection.

This hot water storage tank is intended to be connected to a high efficiency external energy source such as heat pump,
solar device, biomass or district heating. The immersion heaters are intended for backup and supplementary use only. Using
immersion heaters as the sole heat source should be avoided and will lead to higher energy consumption and higher ope-
rating cost.
