- It is recommendable to use filter-dryers
on systems using POE oil.
- Should the POE oil become contaminated
with water, a vacuum pump is no longer
sufficient. Excessive presence of humid-
ity causes sludge and acids that damage
the compressor. Therefore, any contami-
nated oil should be changed or recovered
by means of filters.
- Due to its high hygroscopic nature, POE
oil can cause burns on the skin. The use
of gloves during handling is recom-
mended.
- The POE oils that are adequate for
R-410A systems are as follows:
MOBIL EAL ARCTIC 22 CC (ICI)
EMKARATE RL32CF (ICI)
Specific tools
For installing equipment charged with
R-410A refrigerant and POE oil, the follow-

Notes: WB = Wet bulb. DB = Dry bulb.
(1) This equipment can operate, for a short interval of time, at a temperature beyond limits until the occupied space is conditioned.
ing tools are required:
- Pressure gauges . Specific for R-410A.
High pressure (red) with a range of -1 to
53 bar. Low pressure (blue) with a range
of -1 to 38 bar. With ½" threaded UNF-20
connections.
- Hoses . Of HNBR rubber and with nylon
internal lining. Operating pressure 5.1
Mpa, bursting pressure 27.4 Mpa. ½"
UNF-20 thread.
- Vacuum pump . High vacuum (two stages)
and with adapter to avoid part of the min-
eral oil in the pump from flowing towards
the circuit charged with POE oil. With
adapter for ½" UNF-20 thread.
- Electronic scale . Needed because it is im-
possible to charge R-410A by using a
charge cylinder due to the bubbles caused
by the high pressure and speed of gas
evaporation.
- Refrigerant tank . Adequate for a pressure

of 47 bar and for containing R-410A only
(painted pink). With adapter for ½" UNF-
20 thread.
- Leak detector . Specific for HFC. Sensitiv-
ity of approximately 23 gr. year.
- Recovery equipment . Specific unit for re-
covery of R-410A.
Minimum thickness of tubing
Due to the greater operating pressures of
R-410A refrigerant, the interconnection of
the split units requires seamless DHP cop-
per tubing with thicker walls.
