9.3 Checklist for yearly maintenance
of the outdoor unit
Check the following at least once a year:
▪ Pressure relief valve hose (if present)
▪ Water pressure relief valve
▪ Electrical component box
▪ Water pressure
▪ Water filter
▪ Glycol concentration and pH-value
Pressure relief valve hose
Check whether the pressure relief valve hose is positioned
appropriately to drain the water.
Water pressure relief valve
Turn the red knob on the valve counter-clockwise and check if it
operates correctly:
▪ If you do not hear a clacking sound, contact your local dealer.
▪ In case the water keeps running out of the unit, close both the
water inlet and outlet shut-off valves first and then contact your
local dealer.
Switch box
Carry out a thorough visual inspection of the switchbox and look for
obvious defects such as loose connections or defective wiring.
WARNING
If the internal wiring is damaged, it has to be replaced by
the manufacturer, its service agent or similarly qualified
persons.
Water pressure
Check whether the water pressure is above 1bar. If it is lower, add
water.
Water filter
Clean the water filter.
NOTICE
Handle the water filter with care. Do NOT use excessive
force when you reinsert the water filter so as NOT to
damage the water filter mesh.
