Bad valve or improper water
flow
Check valve settings and ensure water flow is sufficient
(is the filter pump running continually?) If heat pump
continues to cycle, turn unit off to prevent compressor
damage.
Check evaporator coil for severe frost. Turn unit off to
prevent compressor damage. Allow the evaporator to
thaw and restart. If issue continues, call a pool service
provider.
Heat pump is cycling
(on /
off too quickly)
Low refrigerant, low ambient

Condensation
This is normal and there is no reason to be concerned

bottom of unit
Possible water leak
Turn the unit off for several hours, but leave the filter
pump running continuously. If water discharge
ceases, then it is only condensation. Otherwise there is
a possible leak.
