GENERAL INFORMATION

A. Reduce Heat Gain

Theabilityoftheairconditionertomaintainthedesiredinsidetemperaturedepends

ontheheatgainoftheRV.Somepreventativemeasurestakenbytheoccupants

oftheRVcanreducetheheatgainandimprovetheperformanceoftheaircondi-

tioner.Duringextremelyhighoutdoortemperatures, theheatgainoftheRVmay

bereducedby:

● ParkingtheRVinashadedarea.

● Usingwindowshades(blindsand/orcurtains).

● Keepingwindowsanddoorsshutorminimizingusage.

● Avoidingtheuseofheatproducingappliances.
