English

R407C is a zeotropic refrigerant mixture which has zero 
ozone depletion potential and thus conformed to Montreal 
Protocol regulation. It requires Polyester oil (POE) oil 
for its compressor's lubricant. Its refrigerant capacity and 
performance are about the same as the refrigerant R22.

POE or PVE oil is used as lubricant for R407C compressor, 
which is different from the mineral oil used for R22 
compressor. During installation or servicing, extra precaution 
must be taken not to expose the R407C system too long 
to moist air. Residual POE or PVE oil in the piping and 
components can absorb moisture from the air.

Refrigerant R407C is more easily affected by dust of 
moisture compared with R22, make sure to temporarily 
cover the ends of the tubing prior to installation.

SERVICE OF THE FILTER

 Remove any dust adhering to the filter by using a vacuum cleaner or wash in lukewarm water (below 40°C) with a 
neutral cleaning detergent.
Rinse the filter well and dry before placing it back onto the unit.
Do not use gasoline, volatile substances or chemicals to clean the filter.
Clean the filter at least once every 2 weeks. Or more frequently if neccesary.

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT

SERVICE AND  MAINTENANCE

No additional charge of compressor oil is permitted.
No other refrigerant other than R407C.
 Tools specifically for R407C only (must not be used for 
R22 or other refrigerant)

Manifold gauge and charging hose
Gas leak detector 
Refrigerant cylinder / charging cylinder
Vacuum pump c/w adaptor
Flare tools
Refrigerant recovery machine

Filter-dryer must be installed along the liquid line for 
all R407C air conditioners. This is to minimise the 
contamination of moisture and dirt in the refrigerant 
system. Filter-dryer must be of molecular sieve type. For 
a heat-pump system, install a two-way flow filter-dryer 
along the liquide line.
