Safety PrecautionS

WARNING : TO PREVENT PERSONAL INJURY AND / OR EQUIPMENT DAMAGE,

CAUTION - Risk of injury. This equipment should only be operated by certied personnel. Before

operating the unit, read and follow the instructions and warnings in this manual. The operator must be EPA 609

certied and familiar with air conditioning and refrigeration systems, refrigerants, and the dangers of pressurized
components. If the operator cannot read this manual, operating instructions and safety precautions must be
read and discussed in the operator’s native language.

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT. Do not overll storage tank without using provided
oat cable and oat switch. Use only authorized rellable refrigerant tank (with oat switch installed) that meets
DOT specs 4BW or 4BA. Do not exceed the maximum psig rating of the storage tank. Overlling or use of an
unauthorized storage tank could result in serious injury or death.

ALL HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contact with refrigerant may cause
personal injury. Wear correct protective equipment, including safety goggles and protective gloves. Disconnect

hoses using extreme caution.

AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST. Exposure may irritate eyes,
nose, and throat. To remove refrigerant from the A/C system, use only equipment certied for the type of refrigerant
being removed. Use this equipment in locations with mechanical ventilation that provides at least four air changes
per hour. If accidental system discharge occurs, ventilate the work area before resuming service.

CAUTION – DO NOT PRESSURE TEST OR LEAK TEST EQUIPMENT AND / OR VEHICLE AIR CONDITIONING
SYSTEMS WITH COMPRESSED AIR. Some mixtures of air and refrigerant have been shown to be combustible

at elevated pressures. These mixtures, if ignited, may cause personal injury or property damage.

DO NOT MIX REFRIGERANT TYPES THROUGH A SYSTEM OR IN THE SAME CONTAINER. Mixing of

refrigerants will cause severe damage to the unit and the system being serviced.
ALL REFRIGERANT RECOVERED WITH THIS MACHINE IS TO BE RECLAIMED OR DESTROYED. Any

refrigerant recovered with this equipment is to be returned to an EPA approved refrigerant reclamation facility
that will process it appropriately as per AHRI700 standard or dispose of it. Refrigerant recovered with this
equipment cannot be recycled. Recovered mixtures may be ammable and can potentially be ignited causing
personal injury or death.

ONLY RECOVER CONTAMINATED REFRIGERANT WITH THIS MACHINE. Any other use could result in the
contamination of recovered refrigerant with hydrocarbons and/or leak sealants.

HIGH VOLTAGE ELECTRICITY INSIDE THE UNIT HAS A RISK OF ELECTRICAL SHOCK. Exposure may
cause personal injury. Disconnect power before servicing the unit.

TO REDUCE THE RISK OF FIRE, avoid the use of an extension cord because the cord may

overheat. If you must use an extension cord, the cord must be No. 14 AWG and as short as possible. Do not
use the unit in the vicinity of spilled or open containers of gasoline or other ammable substances.

Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.

underStanding refrigerant recovery

Refrigerant recovery is the process of taking refrigerant
out of a system and storing it in a tank. The following
information is critical to achieving the best refrigerant
recovery results.

The 25700 refrigerant recovery machine is capable
of recovering either contaminated R1234yf or R134a
systems.

The 25700 is built and shipped ready to service

•

contaminated R1234yf systems.

The 25700 also includes the hose and connections

•

to service contaminated R134a systems. When an
R134a system needs to be serviced, refer to the
parts list in this manual to determine the necessary

components.

Refer to the Maintenance section of this manual to

•

remove the hose and lter assembly and replace them

with the appropriate components for the refrigerant

being serviced.

Filters

CAUTION: Filters prevent contamination from entering
the unit, which reduces the risk of damage to the unit
and the system being serviced.

The 25700 unit is shipped with a lter screen installed
behind the inlet tting. Robinair recommends the
user clean the lter screen regularly for optimal unit
performance. Failure to use a lter screen will invalidate
your warranty.

Valves

WARNING: To prevent personal injury, open
service and tank valves SLOWLY to allow rapid shut­off of gas flow if necessary. Once it is determined
there is no danger, the valves may be opened fully.

Isolate large amounts of refrigerant and close valves
after use, so if a leak should develop anywhere in the
system, refrigerant will not escape to the atmosphere.

Storage Tanks

WARNING : A storage tank is full when it
reaches 80% volume. DO NOT OVERFILL. Due to
liquid expansion, the tank could explode if filled to
more than 80% volume, possibly causing personal
injury and equipment damage. To avoid overfilling,
use the included float cable in conjunction
with Robinair tank p/n 17990 when recovering
contaminated refrigerant with this machine.

This unit is provided with an 80% capacity shut-off
oat cable. Do not use the 25700 unit without correctly
attaching the oat cable to a storage tank with an
internal oat switch. The unit will automatically shut
down when the storage tank reaches 80% capacity if
the oat cable is used correctly. Use only Robinair tank
p/n 17990 with this machine.

Shut-off Switch

This unit has an internal, high-pressure, shut-off switch.
If system pressure rises above 435 psi, the unit shuts
off. The shut-off switch automatically resets itself after
the pressure drops below 320 psi.

Maintenance

CAUTION :

Keep all connections to the refrigeration system

•

dry and clean. Damage will occur if moisture is
allowed to enter the system.

The 25700 unit is built and shipped ready to

•

service contaminated R1234yf systems. When a
contaminated R134a system needs to be serviced,
see the parts list and Maintenance sections in this
manual to install the necessary components.
