INTRODUCTION
Thank you for purchasing the CPS CR400 series unit. CPS is dedicated to
give you the fastest and most reliable equipment to meet all your commercial
refrigerant recovery requirements.
The CR400 is designed for servicing commercial and residential
refrigeration systems. Simply follow the quick start guide and turn it on.
No need to watch for liquid refrigerant, this unit automatically handles it. Once
the recovery is complete, simply turn the center valve to the
SELF-CLEARING position. Now the unit is ready for the next type of refrigerant.
The CPS CR400 series utilizes a 1/6 hp (0.35kW) compressor, non-restrictive
diaphragm manifold valves, and a liquid regulating valve to make it the first
truly direct liquid or vapor refrigerant recovery unit.
The following are additional features:
• “On the Run” SELF-CLEARING valve. No need to turn off the unit when switching from
recovery to self-clearing.
• On board SUCTION and DISCHARGE gauges.
• 0 to 55 bar (800-psig) discharge gauge to handle R-410A.
• Small physical size.
• Weighs only 12.6 kg (28 lbs.)
• Integrated easy to use carrying handle.
• High Pressure switch set at 550 psig.
• Easy and secure filter accesses. No dangling filters to be damaged.
• Replaceable or cleanable filter cartridge.
• Heavy-duty powder coated aluminum chassis surrounded by a tough High-Density
Polyethylene case.
To help you get a good start, please continue to carefully read the balance of this
manual. This manual contains important information on the proper procedures
for operating this equipment. Please pay close attention to the safety information,
WARNING and CAUTIONS provided throughout this manual. Always remember
“SAFETY FIRST”.

GENERAL SAFETY INSTRUCTIONS
ONLY QUALIFIED SERVICE PERSONNEL SHOULD OPERATE
THIS UNIT. MOST STATES, COUNTRIES, ETC… MAY
REQUIRE THE USER TO BE LICENSED. PLEASE CHECK
WITH YOUR LOCAL GOVERNMENT AGENCY.
DANGER - the recovery tank contains
liquid refrigerant. Overfilling of the
recovery tank may cause a violent
explosion resulting in severe injury or
even death. As a minimum use a scale
to continuously monitor the recovery tank
weight.
CAUTION - avoid breathing refrigerant
vapors and/or lubricant mist. Exposure
may irritate eyes, nose, throat, and skin.
Please read the manufacturers Material
Safety Data Sheet for further safety
information on refrigerants and
lubricants.
DANGER - Avoid breathing refrigerant
vapors and lubricant vapor or mist.
Breathing high concentration levels may
cause heart arrhythmia, loss of
consciousness, or even cause
suffocation.
CAUTION - to reduce the risk of fire,
avoid the use of extension cords thinner
than NO.14 awg. (1,5mm2) to prevent the
overheating of this cord please keep
length to a minimum.
CAUTION - do not use this equipment
DANGER - ELECTRICAL SHOCK in the vicinity of spilled or open
HAZARD - Always disconnect power containers of gasoline or other
source when servicing this equipment. flammable substances. Make certain
that all safety devices are functioning
DANGER - EXPLOSION RISK. Do not properly before operating the
equipment.
recover flammable refrigerants.
This equipment is intended for use of
one refrigerant at a time until the SELFCLEARING feature is used. Mixing of
different refrigerants will cause your
recovered supply of refrigerant to
become contaminated. NOTE: It is very
expensive to destroy mixed or damaged
refrigerants.
CAUTION - all hoses may contain liquid
refrigerant under pressure. Contact with
refrigerant may cause frostbite or other
related injuries. Wear proper personal
protective equipment such as safety
goggles
and
gloves.
When
disconnecting any hose, please use
extreme caution.

ROUTINE MAINTENANCE
FILTER MAINTENANCE - the CR400 is equipped with a 100 mesh screen filter.
This filter should be checked periodically. A partially clogged filter will slow
down the recovery rate of this unit.
Replace the filter cartridge as follows:
1. Use a 7/8” socket or boxed end wrench to loosen the suction port as shown
in Figure 1.
2. Once loose, remove the suction port- filter cartridge assembly is shown in
Figure 2.
3. Either clean the current cartridge or replace with new cartridge.
4. Inspect O-ring. Re-lubricate with compressor oil or equivalent.
5. Place filter back into suction port fitting.
6. Hand tighten this assembly back onto the CR400.
7. Use a 7/8” socket or boxed end wrench to tighten 1/8 of a turn. Do not over
tighten, damage to the O-ring may occur.
8. Check the connection for leaks.

COMPRESSOR OIL MAINTENANCE - the CR400 utilizes a hermetically sealed
oil filled reciprocating compressor. It will be necessary to completely change the
compressor oil periodically.
Change oil as follows:
1. The unit should have no pressure in it. If pressure exists, run Recovery until
suction gauge reads a slight vacuum.
2. Remove the brass cap on the Oil Drain hose located in the lower left-hand
corner of the unit.
3. Lift the unit as shown below in Figure 3. Hold until all the oil has drained out.
4. Inject 8 ounces (240 ml) of SW22 oil back into compressor.
5. Check oil level by tilting the
back of the unit up 1.5"
(4 cm) as shown in
Figure 4. With the Oil Drain
cap removed, oil should
slowly drip out of the unit’s
oil drain port. Add oil if
necessary.
