MAINTENANCE INSTRUCTIONS
4.3. Water-circulating post-heating radiator (option)
For cleaning the water-circulating post-heating radiator, remove the filters and heat recovery
cell. Clean the post-heating radiator while it is in place in the unit either by vacuuming or
by blowing it with compressed air.
4.4. Filter guard (option)
VALLOX 180 can be equipped with an optional filter guard. The filter guard symbol ( )
normally lights up in the main display at speeds 7 and 8, when the filters are clean, and
this does not cause any service activities. If the symbol does not light up at speed 8, the
pressure in the ventilation ductwork of the building differs from the factory setting. In that
case, adjust the filter guard setpoint lower in the inside of the unit (see Section 2.1.5). If the
filter guard symbol lights up at fan speed 4 or 5, the filters need cleaning. If they are clean,
the lighting up may be caused by too dense a mosquito net installed in the external grille
or by the closing of the supply air valves in the rooms. If, after checking these things, the
symbol continues to light up at small speeds, adjust the setpoint greater.
4.5. Condensing water
During the heating season, humidity of extract air condenses to water. Water formation may
be abundant in new buildings or if ventilation is low compared to the humidity build-up
caused by the residents. Condensing water needs to flow out from the ventilation unit without
hindrance. In connection with maintenance, e.g. in autumn before the beginning of the
heating season, make sure that the condensing water outlet (L) in the bottom tank is not
clogged. You may check it by pouring a little water in the tank. Clean if necessary. Do not
let water flow to the electrical parts.
You are able to see the condensing water outlet by removing the socle. The socle is fastened
with two screws. If a condensing water tank is in use, it can be drawn out by pulling it
forward. The tank can be removed for emptying and cleaning.
