

landscaping,walls,fences,etc.,canrestrictairflow).Theheatpumpneedsgoodairflowtooperateatpeakefficiency.
Howmanyhours/daydoesthecirculatingpumpoperate?
Coolerweatherconditions,orheatingtoahigherthannormal,maynecessitaterunningtheheatpumpforalonger

shorterruntimes,inturnleadingtosubstantialenergycostsavings.

WATERCOMINGFROMTHEHEATPUMP...

Isitaleakorjustcondensationfromnormaloperation?Here'showtofindout.
Shuttheheatpumpoff,leavingthecirculationpumprunning.Withinafewhours,thereshouldbeamarked
reductionintheamountofwaterseenaroundthebottomoftheheatpump.Ifthewaterappearstobedryingup,the
waterisprobablyharmlesscondensate,indicativeofnormaloperation.
