Safety Instructions
This manual h as s af et y information a nd i ns tructions to he lp u se rs eliminate or r ed uc e th e risk of
accidents a nd i nj ur ies.
Read and foll ow a ll s af ety informati on , in stallation gu id es , re commended p re ca ut ions, and safe
operating i ns tr uc tions.
GENERAL INFORMATION
A. Thi s air conditi oner / heat p ump is design ed for:
1. Ins tallation o n a recreat ional vehic le.
2. Mou nting on the ro of of a recre ational veh icle.
3. Roo f construct ion with ra fters/joi sts on 16 inc h centers.
4. 2.5 " to 5.5" inch th ick roofs .
B. The e ffic iency of th e air conditi oner / heat p ump will be affec ted by the
cond itions insi de and outs ide of the RV. Redu cing the he at gain of the RV wil l
allo w the air condi tioner / he at pump to func tion with g reater effici ency. Here
are so me suggesti ons to redu ce heat gain in y our RV.
1. Sel ect a shaded ar ea to park yo ur RV
2. Clo se windows an d utilize t he blinds and / o r curtain s.
3. Kee p doors shut.
4. Avoid us ing applian ces that prod uce heat.
Beginning the cooling / heating process early in the day will greatly improve the heat pump’s
ability to maintain the desired temperature.
In high temperature and high humidity environments, the air conditioner / heat pump should be
set in Cool mode with the Fan Speed in the high position, This will allow for optimal cooling
efficiency.
C. Con densation
The ma nufacture r of this air c onditione r / heat pump w ill not be resp onsible f or
dama ge caused by co ndensed m oisture on ce ilings or o ther surfac es, Air cont ains
mois ture and this m oisture t ends to conde nse on cold s urfaces, Wh en air enters
the RV, co ndensed m oisture may a ppear on the ce iling, wi ndows, meta l parts, et c.
The ai r condition er / heat pum p removes thi s moistur e from the air du ring cool ing
