Operation and maintenance
At least every 3 months:
The filters should be cleaned and renewed when needed. Usually the filters need to be renewed
once every 3 month. The filter guard in the CTS 700 control can be used in order to make sure that
the filters are checked. The filters can be cleaned by vacuuming or shaking them.
Changing filters:
1. Loosen screws
2. Remove the filter hatch
3. Pull out the two filter frames for change/vacuuming
Once a year:
-
The sacrificial anode must be checked to ensure that monitoring of the anode is intact.
o
The wire “yellow/green” is dismantled at the anode.
This produces the “Anode fail”
o
The wire “yellow/green” is reassembled at the anode.
Delete the alarm in the event log (reset). Delete is only for installation contractors.
The hot-water tank can corrode if the anode is left unchanged.
-
The intake should be inspected and any uncleanness should be removed.
-
The evaporator should be inspected and cleaned.
-
It should be checked that the condensate has free passage through the water seal and the
condensation drain.
-
The safety switch for the hot water tank should be controlled.
-
It is recommended to take out a subscription for service.
