ELECTRICAL SAFETY
When using an extension cord it should be a 3-wire, 14
AWG minimum and no longer than 25 feet.
cWARNING! Whenever you perform any type
of maintenance work on your ProVax, insure
that it is disconnected from the power supply
before you begin.
FIRE SAFETY
i WARNING: TO REDUCE THE RISKOF FIRE:
Never operate unit in an explosive environment!
Do not use this equipment in the vicinity of spilled or
open containers of gasoline or any other flammable
liquid.
Use this equipment in locations with mechanical venti-
lation that provides at least four air changes per hour
or locate the equipment at least 18 inches above the
floor.
Never use oxygen when testing for leaks.
Any oil in contact with oxygen under pressure will form
an explosive mixture.
REFRIGERANT SAFETY
ProVax is approved for use with the following
category III, IV and V refrigerants (Per ARI 740):
R-12, R-22, R-134A, R-401A, R-401B, R-401C,
R-402A, R-402-B, R-404A, R-406A, R-407A,
R-407-B, R-407C, R-407D, R-408A, R-409A,
R-410A, R-411A, R-411B, R-412A, R-500, R-502,
R-507 and R-509
Always open service and cylinder valves slowly.
This allows rapid control of the flow of gases if
there is any danger. Once it is determined that
there is no danger, the valves can be opened
fully.
Always isolate large amounts of refrigerant and
close off valves after use, so if a leak should
develop anywhere in the system, the refrigerant
will not escape.
Keep all connections to the refrigeration system
thoroughly dry and clean. If moisture enters the
refrigeration system, it is likely to cause consider-
able damage.
cWARNING!
Pressurized tank contains liquid refrigerant.
Never overfill storage tanks. Overfilling of the tank
may cause a violent explosion and possible injury
or death. Do not exceed the working pressure of
Recovery Tank cylinder.
