General
Check/tighten all electrical connections
Every 6 months

Check operation of the drain line heater and examine for cuts and
abrasions
Check/tighten all mechanical/flare connections
CAUTION
Failure to keep the condenser coil clean will result in reduced airflow through the
condenser, resulting in poor system performance and premature compressor failure.
MISE EN GARDE
Le manquement à maintenir la propreté du serpentin réfrigérant aura pour
résultat une réduction de la circulation d’air dans le condenseur, entraînant
un rendement médiocre du système et une défaillance prématurée du
compresseur.
Polyol Ester (POE) Lubricants:
Polyol Ester (POE) lubricants quickly absorb moisture from the ambient surroundings.
POE lubricants absorb moisture more rapidly and in greater quantity than conventional
mineral oils. Because moisture levels greater than 100 PPM will result in system
corrosion and component failure, it is essential that system exposure to ambient
conditions be kept to a minimum.
If a system is left open to the atmosphere for more than 15 minutes, the liquid line drier
and compressor oil must be replaced. Drain at least 95% of the oil from the compressor
suction port. Measure the amount of removed oil, and replace it with exactly the same
amount of new POE oil. Mobil EAL™ ARCTIC 22 CC is the preferred Polyol Ester
