Special safety instructions

1. Unit is intended for operator professionally well trained, he must know refrigeration founda-
mentals, cooling systems, refrigerants and possible damages that equipments under pres-
sure could cause.
2. Read carefully instructions in the literature, strict observance of procedures is main condition
for operator safety, constant declared performances and unit undamaging.
3. Wear safety glasses and gloves when handling refrigerant; avoid contact with refrigerant,
blindness and injuries may result to operator.
4. Keep away from flames and hot surfaces; high temperature decomposes refrigerant releas-
ing toxic contaminants very dangerous for environment and operator.
5. Avoid skin contact; refrigerant has a very low boiling temperature (approx. -18°C / -3°F) and
freezing may occurs.
6. Avoid inhaling vaporized refrigerant gas; it has a narcotic effect.
7. Vacuum pump must always be suitably earthed.
8. 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.
9. Vacuum pump is air cooled with integral fan; use only where air can freely circulate.
10. During operations, do not vent refrigerant in environment.

Instructions for use
3 Description
Vacuum pump for air evacuation of closed systems (air conditioners, tanks, etc). This equipment
is specially designed for HVAC&R systems.
The two Stages of these pumps 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.
