Split Inverter Air-to-Water Heat Pump

Section 7: Maintenance/Troubleshooting

  All  repairs  and  troubleshooting  should  be  performed  by  a  qualified/licensed  technician.  Repairs/troubleshooting 

improperly can void the product warranty and could result in injury, death or premature failure of the product. Please contact Mestek 

technical support for any issues not covered in the following tables. 

Repair

Condition

Possible Cause

Solution

Reduced heating capacity

Excessively frosted Coil

Ensure Defrost function is enabled and adjusted for local condtions. 

Vegetation or debris too close to the 

outside coil, blocking airflow

Clear space around the outdoor unit according to the drawings in the Unit 

Installation section

Fouled or dirty outside coil

Clean outside coil fins with commercial cleaner. Take care to avoid 

bending or crushing fins

Reduced fan performance

Review the fan parameters F04 to F07 to ensure that the fans are 

reaching maximum speed at design heating conditons. Inspect fans for 

damaged or missing blades.

Extremely cold ambient termperature

It is normal for the heating capacity to be reduced as the outdoor 

temperature falls.

Excessive frost on outside 

coil in heating

Some frost visible on the fins is 

normal, but excessive ice blockinig 

airflow should be addressed

Ensure Defrost function is enabled and adjusted for local condtions. 

Innacurate Coil Temperature Sensor

Verify Status reading temperature 06 against known device placed on coil 

outlet plumbing

Reduced Cooling Capacity

Insufficient water flow

Ensure the pump is in good operating conditon, and is able to provide at 

least 12 GPM against the entire system pressure drop. Check plumbing 

system for blockage or restristive pipe size or fittings. 

Vegetation or debris too close to the 

outside coil, blocking airflow

Clear space around the outdoor unit according to the drawings in the Unit 

Installation section

Fouled or dirty outside coil

Clean outside coil fins with commercial cleaner. Take care to avoid 

bending or crushing fins

Reduced fan performance

Review the fan parameters F08 to F11 to ensure that the fans are 

reaching maximum speed at design cooling conditons. Inspect fans for 

damaged or missing blades.

Abnormal Compressor noise Liquid slugging due to overcharged 

refrigeration system

Ensure the system is charged by weight of refrigeration, with adjustments 

according to unit Rating Label and SIS Charging Table

 Excessive Discharge Pressure

Ensure sufficient outdoor airflow in Cooling, or indoor water flow in Heating
Supply water temperature should not exceed 140 deg F

Low input voltage

Ensure line voltage is a minumum of 220V during steady state operation

Damaged or failed compressor
