Vacuum Pump Models QV2 & QV5
Introduction
Thank.you.for.selecting.Bacharach.products.for.your.refrigeration.
equipment.needs ..To.ensure.your.safety,.and.for.the.safe.operation.
of.this.equipment,.please.read,.understand,.and.follow.the.informa-
tion.contained.in.this.instruction.manual ..
The.Model.QV2.and.QV5.are.two-stage,.rotary.vane.vacuum.
pumps.designed.to.evacuate.moisture.and.air.from.refrigeration.
systems.(e .g .,.R-12,.R-22,.R-134a) .
Features
• Anti-oil-return
.–.A.check.valve.prevents.pump-oil.from.entering.
the.evacuated.system.after.the.pump.stops .
• Environment protection
.–.A.built-in.filter.eliminates.oil.mist,.
and.an.oil-gas.separator.removes.oil.contamination.from.the.
.exhaust .
• Aluminum alloy motor casing
.–.The.motor.casing.is.an.alumi-
num.alloy.that.has.high.rate.of.heat.dissipation,.which.provides.
for.continuous.pump.operation ..
• Two stage design
.–.The.second.stage.of.the.two-stage.design.
starts.pumping.at.a.lower.pressure.to.pull.a.deeper.ultimate.
vacuum .
• High starting torque
.–.Designed.for.low.temperature.and.low.
voltage operation, the pump will start in temperatures ≥40 °F
(≥5
°
C), at its rated input voltage of 110 VAC ±10%.
• Oil circulation design
.–.Offset.rotary.vanes.work.in.conjunction.
with.the.vacuum.pump.oil.to.create.high.compression.within.the.
pumping.chamber .
