6.1 Low voltage during high load conditions Check supply voltage for excessive line drop.
6.2 Loose power wiring Check all connections and tighten.
6.3 High condensing temperature See corrective steps for high refrigerant discharge
pressure.
6.4 Power line fault causing unbalanced voltage Check voltage. Notify the power company. Do not start
until corrected.
4.2. Compressors
Oil change is not compulsory for factory- made systems. In the case of “field installations”, it is
recommended to change the oil for the first time after approximately 100 operating hours. During
oil change, also clean oil filters and magnetic plugs for compressors with integrated oil pump.
After that, change the oil and clean oil filters and magnetic plug approximately every 2 years.

A yearly oil analysis is recommended to boost compressor reliability.
4.3. Air Cooled Condensers
Periodical cleaning of finned surfaces can be done by washing down dust with warm water spray
and a mild detergent. Do not use an alkaline or acidic solution as it will attack the coil material.
The inner face of the coil may be cleaned by the access panel on the side of the units or by
removing the fan guards.
Always pressure clean in reverse of the air flow.
