To Next PageTo Next PageWhat to do if the fans do not operate on my SystemAir Heat Pump?
If the fans of your SystemAir Heat Pump do not operate, check the connections if there are electrical circuit problems. Contact an approved Service Centre if there is an internal circuit thermal cut-out activated.
What causes low oil level in the compressor of my SystemAir Heat Pump?
If there is low oil level in the compressor of your SystemAir Heat Pump, locate and repair the leaks if there is a presence of one or several oil or gas leaks in the circuit. Contact an approved Service Centre if there is mechanical compressor damage. Check the electrical circuit and the condition of the resistance, and replace defective parts if necessary if there is a sump oil heater resistance fault.
How to resolve insufficient water circulation in my SystemAir SysAqua 25?
If there is insufficient water circulation in your SystemAir Heat Pump, bleed the air via the safety valve if there is air in the circuit. Clean the hydraulic side of the evaporator with a reversed water flow if there are deposits or impurities in the evaporator.
What to check if my SystemAir SysAqua 25 is not operating with no alarm?
If your SystemAir Heat Pump is not operating and there is no alarm activation, check the pump if there is a water circulation fault. Check the flow controller if the flow controller is inoperable. Check the differential pressostat if the differential pressostat is inoperable.
