7. Maintenance
Follow the following instructions to achieve optimal
performance:
Before opening the device, turn off the power,
pull out the plug and wait until the fan is
completely quiet.
After installing for the first time, check after a couple of
days that the condensation outlet is working.
Environmental requirements:
When repairing or dismantling the device, statutory
environmental regulations must be observed regarding
recycling and destruction of various materials.
7.1 Device
Filters:
The filters must be changed when “change filter” flashes
in the control panel display.
Use the device’s circuit breaker to stop the device or use
the circuit breaker on the terminal box. Open the front
and remove the filters. Reset the filter timer when the
filters have been changed. You can make an adjustment
in the operating menu if you wish to change the filters
with a different time interval
.
There is a danger of cuts from sharp discs. The
discs must not be damaged.
Vacuum cleaning or using pressurised air
on the filters is not recommended. Filter
performance may be impaired.
Condensation water and condensation outlet:
The condensation trays must be cleaned of dirt every
autumn. Fill the condensation trays with water and check
that the water drains away. If not, the outlets must be
cleaned. Check that the vaporisor discs are also clean.
Heat exchangers:
The heat exchangers should be inspected every 3 years.
If it is dirty, remove it and wash it in warm water with soap
and rinse with a hand shower.
Fans:
Inspect the fans every three years for dirt in the fan
wheels. Remove the front cover from the device. Clean
the fans with a brush, a bottle cleaner or a paint brush.
Make sure that the counterbalancing weights on the fan
wheels are not removed, as this will lead to disequilibrium
and cause a higher level of noise and also cause wear to
the fans.
Air supply and extraction valves:
Clean the valves by drying with a dry cloth. Take care that
the valve does not turn around, causing a change in air
volume.
7.2 Water circuit and tank
Safety valve:
In connection with the service water container, the
installer has installed a safety valve at the cold water tap.
This valve is installed to protect the container against
overpressure when the service water expands under
heating. The non-return valve that is fitted before the
safety valve on the cold water pipe prevents the water
from flowing back into the cold water pipe. The pressure
in the container therefore increases to the safety valve’s
maximum. If this happens, the safety valve opens and the
excess water flows away. If the safety valve will not open,
the container will burst.
In order to ensure that the safety valve is working
correctly, it should be inspected several times each year.
To test it, press on the handle on the safety valve and
ensure that the water can flow away. Damage that occurs
due to a blocked safety valve is not covered by the
guarantee.
Anode:
In order to prevent corrosion of the enamel service water
container, it is equipped with a magnesium anode that
is fitted at the centre of the container. The anode has
an estimated lifetime of about 2.5 years. However, you
should check that the anode is intact. It is recommended
that the anode is inspected every two years and replaced
if it is worn and has a diameter of about 6-10 mm.
To inspect the device, disconnect the power before
removing the front cover. The service water container
must be emptied of water before it is possible to remove
the anode. To do this, close the cold water supply and
connect a hose to the drain valve so that the water from
the container can drain out to the closest outlet.
While the container is emptying of water, open a hot
water tap so that negative pressure does not occur in the
container. When the container is empty, the anode can be
screwed off and inspected.
G4 = Standard filter (Coarse filter class G4).
F5 = Fine filter (Fine filter class F5).
F7 = Fine filter (Fine filter class F7).
