Vortex Operating Manual
Compressor starts but
cuts out within a few
minutes — pressure
indication on HP gauge
is high
• V2 is in Purge position
and HP switch activates
• V3 not open and HP
switch activates
• Recovery tank valve
not open
• Blocked discharge
hose
• Air in system/tank
• Rotate V2 to Recovery
• Rotate V3 to open
position
• Open tank valve
• Check & clear blockage
• Bleed air from
system/tank
Compressor stops
intermittently
• Vapor pressure of
refrigerant in tank is
close to HP trip point
• Thermal overload
switch in compressor is
activating
• Reduce tank
temperature
• Reduce amount of
liquid being pumped and
let machine cool down
before proceeding
Unit overheats Excessive head
pressure due to:
• High ambient
temperature
• Restricted discharge
hose
• Air in recovery tank
• Reduce tank
temperature
• Check & clear
restriction
• Bleed air from tank
Recovery process too
slow
• Head pressure too
high
• System refrigerant
iced up
• Compressor seals are
worn
• Reduce tank
temperature or change
tanks
• Throttle gauge manifold
valves and V3 to reduce
pressure differential
between LP and HP
gauges
• Interrupt process to
allow ice to dissipate
• Rebuild compressor
with service kit — check
with wholesaler for
assistance
