Refrigerant And Lubricant - Personal Protective Equipment And Precautions; Hoses Connection; Precautions For Handling And Use Of R134A Fluids - wow! WAC 2200 Manual De Instrucciones

- Only use the oils recommended by the manufacturer.
- Never confuse the vacuum pump oil with the oil for the air-conditioning systems.
Failure to comply with any of these safety rules leads to any form of guarantee for the machine
being rendered null and void.
Machine is provided with class III safety valve, in case of malfunctioning it can create an
external sack of flammable gas; keep the machine in well ventilated area.
WARNING: R134a and/or R1234yf vapor/gas refrigerant are heavier than air and may thicken
on the floor or inside the cavity/pits and cause choking by reducing oxygen available for
breathing.
At high temperatures the refrigerant decomposes releasing toxic and caustic substances,
hazardous for the operator and the environment. Avoid inhalation of the refrigerants and A/C
system oils .
Exposure can irritate the eyes and airways.
WARNING! The machine must be connected to a socket with effective ground
REFRIGERANT AND LUBRICANT - PERSONAL PROTECTIVE EQUIPMENT
AND PRECAUTIONS
Handled with caution refrigerants and pressure vessels, since otherwise there could be health
risks .
The operator must wear safety glasses, gloves and suitable clothing to work , contact with
refrigerant may cause blindness (eyes), and other physical damage (frostbite) to the operator.
Avoid contact with the skin, the low boiling temperature (about -26°C for R134a and about -
30°C for R1234yf ) can cause cold burns.
Do not change the setting of the relevant devices for safety, do not remove the seals of the
safety valves and control systems . Do not use external tanks or other storage containers that
are not approved, or without safety valves.
During the functioning, the air vents and
ventilation equipment must not be blocked or
covered

HOSES CONNECTION

Hoses may contain refrigerant under pressure. Before substitute the quick coupler verify the
corresponding pressure in the service hoses (gauge).
The machine is equipped with the following safety devices:
SAFETY PRESSURE: stops the compressor in case of excessive
pressure
SAFETY VALVE: opens when the pressure inside the system reaches a
level of pressure above the estimated limits.
MAIN SWITCH: allows the machine's turnoff by sectioning of the power
line. Prescribing however disconnection from the mains plug of the power
cord before servicing
IT IS NOT ALLOWED ANY KIND OF TAMPERING OF THE SAFETY
DEVICES MENTIONED ABOVE

PRECAUTIONS FOR HANDLING AND USE OF R134a FLUIDS

Refrigerant fluids expand to the gaseous state in standard environmental conditions. In order
that they may be shipped and used they must be compressed into suitable bottles. We
therefore recommend observing all the general precautions applicable to handling of
pressurized containers. In the case of R134a in particular, we suggest the following special
precautions. Avoid inhaling highly concentrated vapors even for short periods of time, since
