CooiTech® high performance vacuum pumps
••••••••••••••••••••••••••••••••••••••
Congratulations
on
purchasing one of Robinair's
top quality CooiTech® vacuum pumps. Your pump
has been engineered specifically for air condition-
ing and refrigeration service, and is built with
Robinair's proven offset rotary vane for fast,
thorough evacuation.
You'll appreciate these key features ...
lso-Valve™
Allows the pump to
be
shut off while still con-
nected to the A/C-R system, which
is
handy for
checking rate of rise. With the valve handle
in
the
"Open" position, the pump is open to the system
being evacuated.
In
the "Close" position, the
pump
is
isolated from the system.
High vacuum rating
The two-stage, offset rotary vane design provides
powerful, quiet high vacuum capability and
assures moisture removal, while the high
pumping capacity reduces evacuation time.
Multiple refrigerant capability
This pump can
be
used for R-12, R-22, R-500
and R-502, as well as for R-134a. The inlet "tee"
has both
1
/4"
MFL and
1
/2"
Acme fittings to accom-
modate hoses from either type of manifold.
Directed exhaust
The exhaust is expelled through the handle to
direct it away from the service technician.
Gas ballast
A precise amount of atmospheric air
is
introduced
into the pump, preventing condensation of
moisture vapor and helping maintain the purity of
the pump oil.
By
using the gas ballast, the pump
operates more efficiently and pump life
is
extended.
Sure-grip handle
The one-piece, molded handle makes it easy to
carry the pump to and from job sites, and the
handle stays cool to the touch during operation.
Compact design
Your pump measures approximately 40
em
long,
while aluminum housing and offset rotary vanes
keep the pump weight low, making
it
easy to
carry.
