Precautions for R407C outdoor units
R407C outdoor units use synthetic oils which are extremely hygroscopic. Therefore ensure that the
refrigerant system is NEVER exposed to air or any form of moisture.
Mineral oils are unsuitable for use in these units and may lead to premature system failure.
Use only equipment which is suitable for use with R407C. Never use equipment which has been used
with R22.
R407C should only be charged from the service cylinder in the liquid phase. It is advisable to use a
gauge manifold set equipped with a liquid sight glass fitted in the centre (entry) port.
