Denitions
Denitions of safety precautions
Danger: refers to imminent and severe risk.
Failure to comply with instruction will result
in serious injury or death.
Warning: refers to a potential but severe risk.
Failure to comply with instruction could result
in injury or death.
Caution: refers to a limited risk. Failure to
comply with instruction could result in minor

Caution! The water heater must be lled
with water before electrical supply is turned
on, or guarantee becomes invalid.
Warning! Electrical installations and repairs
must only be carried out by an electrician.
Caution! Water installations and repairs
must be carried out by a plumber.
Warning! When emptying the tank, make
sure the electrical supply is swiched off
before the plug is opened.
Caution! Using products which do not meet
specied requirements, for example spare
parts or uids, or not appropriately trained
personnel for your Høiax product may void or
limit the warranty.
Warning! Misuse or improper treatment of
safety valves, thermostats or electric
elements and wirings may result in an explosi-
on due to pressure build-up. Safety
valves must not be blocked.

General description
Høiax water heaters are manufactured to
resist higher amounts chlorides and build-up
of calcium deposits.
The water heater can manage up to 250 ml
Cl/l water without corrosive effects. The
outer jacket material is chosen to prevent
corrosion when the heater is placed in damp
or aggressive environments.
The water heaters has less than 70 watts of
heat loss and offers a maximum water
temperature of 95°C for heatwater needs.
The termostat is set at 75°C from factory.
The water heaters are equipped with an
adjustable mixing valve and a hotwater
outlet. The mixing valve can be connected
from any direction, providing lower
temperature for household appliances if
needed.
In water with a hardness level above 6°dH,
Høiax Agri Export 250 DT (double tank) is
preferred.
Using two heaters
In areas where the water has higher
concentration of minerals, it is possible to
use two water heaters for lowering the
precipitation, and increasing the time
between cleaning.
When water temperature rises above 60°C,
the precipitation increases. To increase the
timespan between maintenance cleaning,
the water heater can be connected in series
with a simpler or equal heater, which
pre-heats the water up to 60°C.

Installation
Requirements
• The installation should be done according
to existing norms for water supply and
sewage system.
• The heater must be placed in a room with
drainage.
• Cold and hot water pipes must be in
copper or stainless steel. The connection
is made with a 15 mm clamp ring
connection.
• If using plastic piping, the mixing valve's
cold and hot water connections must rst
be connected to copper pipes (at least
0.5 m long) before being connected to the
plastic pipe. The mixing valve and the
internal cold water pipe must be tightened
before connection.
• Incoming cold water pressure must be at
most 6 bar. When higher, a pressure
reducing valve must be installed.
• The overow pipe for the safety valve
must have an internal dimension of at
least 18 mm. The pipe must have a
steady decline to drainage.
• The design allows installations in damp
areas such as milkrooms, bathrooms,
kitchens, laundry and such. This does not
include saunas or areas with similar
humidity.
Warning! Electrical installations and repairs
must only be carried out by an
electrician.
Caution! Water installations and repairs
must be carried out by a plumber.

Installation
Caution! The water heater must be lled
with water before electrical supply is
turned on, or guarantee becomes invalid.
Installation procedure
1. Place the water heater so that the
electrical switch will be easily accessible
and with enough space for maintenance to
be possible. Make sure the safety valve has
free drainage.
2. Mount the pipes.
3. The electrical cover is removed by
pressing a screwdriver on the snap-hooks.
The wires can be tted into the grooves
under the heater. (Drainage pipes with
diameter less than 20 mm can also be tted
into the grooves.)
If the electric connection is done with xed
wiring, the water heater must be preceded
by a switch disconnector on the power feed
cable.
Recommended fuse for main supply
(3000 W): 400 VDC = 10 Amp., 230 VDC =
16 Amp.
4. Adjust the thermostat by using a at
screwdriver to turn the screw to the correct
set point.
5. Reattach the plastic cover by rst
inserting it at the top and then pressing it in
to xed position at the bottom.
6. The cover for safety valve snaps into
place below the lid.
7. Verify the installation by turning on the
electrical power supply. Remember that the
water heater needs to be lled before power
is turned on.
Water temperature from the mixing valve
should be kept below 60°C to prevent
scalding. Adjust by turning the temperature
wheel (M) to + for warmer, or - for colder.
Note! When new, the water heater
must be ushed with fresh water for
about 30 minutes.

Maintenance
Maintenance guidelines
Note! When new, the water heater must be
ushed with fresh water for about 30
minutes.
Warning! When emptying the tank, make
sure the electrical supply is swiched off
before the plug is opened.
Cleaning procedure
The cleaning interval differs depending on
the water hardness, quality and temperature.
First service should be made after 6
months, and thereafter adjusted to local
conditions.
• Disconnect the power supply and close
the cold water inlet valve.
• Open a hot water tap.
• Open the drain valve and drain the water
heater.
• Open the electric lid, disconnect the
wiring to the electric element and remove it.
• Clean out pressure tank for calcium
deposits by entering through the hole
where the heating element was located.
Cleaning can be done with a wet vacuum
cleaner. Clean out as much as possible
from the bottom of the water heater.
• Remove the calcium deposits from the
heating element. If necessary, a solvent
mixture of phosphoric acid or citric acid
can be used (conc. 10%).
Caution! Do not use any tools that could
scratch the surface of the heating element!
• Check thoroughly for damages in surface
of the heating element. Replace if
necessary.
• Reattach the heating element and
reconnect the wires.
• Close the drain valve.
• Open the cold water valve and let the
heater be lled with water.
• Close the hot water tap.
• Close the electric lid and connect the
power supply.
Testing safety valve
The safety valve prevents high pressure
build-up when the water is heated, by
opening and let the expanded water out
through the overow pipe.
The safety valve must be operated manually
every 12 months to ensure unrestricted
drainage.

Troubleshooting
Water from mixing valve isn’t hot enoughisn’t hot enough • Check for any leaking hot water taps.
• Open mixing valve fully.
• Increase the thermostat temperature.
Water from hot water outlet isn’t hot enoughisn’t hot enough Increase the thermostat temperature. Check temperature on
hot water taps from mixing valve. If needed, close mixing valve
sliwater taps from mixing valve. If needed, close mixing valve
slightly so that water from mixing valve is below 60°C.
No hot waterNo hot water • Check fuses and/or power supply.
• Reset the thermal cut out thermostat by disconnecting
electrical electrical supply and push the reset button located
on the electrical terminal connector.
• If the water heater still does not heat, replace electric heating
element.
Leakage from safety valveLeakage from safety valve This is normal if a pressure reducing valve is installed.
Water is too hot If the temperature for any reason should rise above 95°C, the
high-temperature cut-off will cut the current temperature at
99erature cut-off will cut the current temperature at 99°C. If this
occurs, make a smaller hot water tapping to reduce thethis oc-
curs, make a smaller hot water tapping to reduce the tempera-
ture, switch off power supply and push the reset button located
on the electrical terminal connector. Call for expert help if
electric heating is not restored.
