Thebenefits of installingapprovedindoorand outdoor

performanceandthebest overall reliability.
Thefollowingchargingmethods are therefore
prescribedformatched systems with indoorTXVs/

1. Subcooling(inthecooling mode)istheonly
recommendedmethod of chargingabove55°

2. Forbest results — theindoortemperature should
bekept between 70° to 80° F. Add systemheatif

3. At startup, orwhenever chargeis removedor
added, thesystem must beoperatedforaminimum
of (20) minutestostabilizebefore accurate
measurements can bemade.
4. Measure Liquid Line Temperature andRefrigerant
Pressure atservicevalves.
5. Determine totalrefrigerantline length, andheight
