Safety Devices - Bosch RG8.0 Manual Original

R
Some refrigerant may not be used in environments
with a risk of explosion. Fire, naked flames and
smoking are prohibited. No welding or soldering is
allowed. High temperatures and UV radiation may
cause refrigerant to chemically separate. The result-
ing products cause cough and nausea.
R
Refrigerants should never be mixed within a system.
Comply with your local regulations for handling and
storing of recovered refrigerant.
R
Additionally, recovery tanks should always be placed
on a refrigerant scale to monitor the filled quantity.
R
Use only approved tanks with a minimum of 41 bar
working pressure that comply with local regulations.
R
Recovery tanks are designed for different pressures.
Do not exceed the working pressure of each tank.
R
Never transport an overfilled tank. Safety codes rec-
ommend that hermetically sealed tanks should not
be filled more than 80% of its capacity with liquid.
The remaining 20% is called head pressure room.
Refrigerant expands when temperature increases
and may cause a tank to explode if overfilled. Refer
to the following table:

Danger: Risk of explosion
The pressure switch does not prevent over-
filling of a tank. If the RG8.0 / RG4.0 stops
due to high pressure, the tank might be
completely filled and can lead to explosion.
¶
Do not overfill the tank.
¶
Ensure that you monitor the weighing
scale regularly.
R
A scale must be used to avoid overfilling the storage
tank.
R
Cover the ports of the storage tank with caps to
prevent refrigerant leakage.
R
Tanks and filters should be designated for one refrig-
erant only and clearly marked as to which refriger-
ant they contain and/or are designated for use with.
Refrigerants should never be mixed within a system.
Comply with your local regulations for handling and
storing of recovered refrigerant.
R
Special care should be taken when recovering from a
burned-out compressor. Use two high capacity acid
filters, in series. Bosch recommends using
Alco® type EK-162-F or Sporlan® type C-162-F.
R
The RG8.0 / RG4.0 can be used only in a sheltered or
indoor environment.

Safety devices

R
Pressure switch - Cuts off the power supply to the
motor if the normal operating pressure exceeds
38.5 bar.
R
Circuit breaker - Terminates the power supply in
case of over current drawn by the RG8.0 / RG4.0 .
