INSTRUCTIONS FOR USE
Safety precautions
Unit is intended for operator professionally
well trained, he must know refrigeration
foundamentals, cooling systems, refrigerants
and possible damages that equipments under
pressure could cause.
Read carefully instructions in the literature,
strict observance of procedures is main
condition for operator safety, constant declared
performances and unit undamaging.
Wear safety glasses and gloves when handling
refrigerant; avoid contact with refrigerant,
blindness and injuries may result to operator.
Keep away from flames and hot surfaces;
high temperature decomposes refrigerant
releasing toxic contaminants very dangerous
for environment and operator.
Avoid skin contact; refrigerant has a very low
boiling temperature (approx. -18°C/-3°F) and
freezing may occurs.
Avoid inhaling vaporized refrigerant gas; it has
a narcotic effect.
Vacuum pump must always be suitably
earthed.
Even if the pump temperature is not expected
to rise a high level during use, it is advisable
to locate the unit so that users cannot make
contact with the casing, as burns may result.
Vacuum pump is air cooled with integral fan;
use only where air can freely circulate.
During operations, do not vent refrigerant in
environment.

Description A - B - C
Vacuum pump for air evacuation of closed systems
(air conditioners, tanks, etc). This equipment is
specially designed for HVAC&R systems.
The Double Stage of these pump make it feasible to
achieve the final vacuum level requested for these
type of systems. Besides, the solenoid non-return
valve avoids any oil mixture due to the backflow
after a power interruption or any other process
interruption.
