ABOUT: Recovery & Recycle Systems
by Robinair®
For years, R-134a was cheap and plentiful. Today it's a different story – refrigerant is much more
expensive and not always available.
The Robinair® 34988, 34788 & 34288 recover up to 20% more
refrigerant, which means it will cost less to recharge the system. The best charge accuracy that could
be claimed by older generation service machines was +/- 1 ounce, a 3% error on a two-pound system.
That same charge accuracy on a 14-ounce system is over twice the error (7%). Early R-134a systems
could still provide some cabin cooling when they were 4-6 ounces (12-18%) low on refrigerant.
However, new designs are so efficient, they do not have reserve refrigerant, and charge accuracy
is critical.
The 34988, 34788 & 34288 will recharge the vehicle to within 1/2 ounce of the charge
capacity, and you will avoid the dreaded "come back". As the shop owner, you will realize more
profits per service by recovering more refrigerant and charging less.
Four Systems to Choose From:
34288: Semi-automatic Cool-Tech.
34788: Fully automatic Cool-Tech.
34788-H: Fully automatic Cool-Tech with Hybrid capabilities.
34988: Fully automatic, premium Cool-Tech.

User Manuals
Instructions for safety, operation, maintenance of each product, and more, is available in the Unit's User Manual. Copies can be downloaded in the section linked below:
Maintaining Your Recover, Recycle and Recharge Equipment
Performing regular maintenance check-ups will
help keep your recover, recycle and recharge
equipment in great condition and provide you
with many years of dependable service.
Recovery, Recycle, and Recharge machines are
built to provide years of reliable service. However,
it is an electro-mechanical device and as such does
require routine maintenance. Regular service intervals
will help keep the machine running at peak performance
levels. It is important to always read and follow
manufacturers recommended service procedures.
Some of the items that require regular inspection
are as follows:
- Service Couplers
Typically dirt and debris in the service environment are the
main causes of service couplers failure. Technicians must
inspect the receiving end of the coupler to make sure it is
clean and oil free. Also inspect the O-rings to make sure they
are pliable and free of cuts or gouges. Finally, inspect the
valve to ensure it is free of dirt and turns freely.
- Hoses
It is important to inspect the hoses for cracked, abraded, or
blistered areas. Cracks and abrasions indicate external wear
whereas blisters generally indicate internal problems. If any
of these wear indicators are present, it's best to replace the
hose. Also inspect the hose crimps and fittings on the end of
the hoses as well as valve core depressors to make sure they
are free of dirt and operate freely. Double check the gaskets
for wear and pliability.
- Refrigerant Scales
Refrigerant scales ensure that the correct amount of refrigerant is charged into the vehicles A/C system. Follow the
manufacturer's procedure for checking scale accuracy at
least once per year or after service on the unit has been
performed. If the unit is equipped with a DOT tank,
examine it to make sure it is up to date.
- Filters
While the inspection covers are still off, it is an ideal time
to change the filters if necessary. Some recovery machines
keep track of filter life based on the number of pounds of
refrigerant filtered and prompt the user when it is time to
change the filter. Some manufacturers recommend a filter
change after servicing a certain number of vehicles. Either
way, a properly maintained filter will keep the recovery
machine running at peak performance. Always remember
to inspect the gaskets and threads when changing filters.
- Vacuum Pump Oil
If the recovery machine comes with a vacuum pump, make
sure to change the pump oil when required. Vacuum pump
oil is hydroscopic, which means it has an affinity for absorbing water, resulting in rust or scale build-up on internal
components. Be careful not to overfill the vacuum pump.
When this occurs, oil will discharge in the exhaust air and
settle on other internal components attracting more dirt
and debris. It may also cause the vacuum pump to smoke,
prompting a service call.
- General Maintenance
The machine itself has several internal components that
should be inspected to ensure many years of dependable
service. About every thirty days the unit should be inspected
with an electronic refrigerant leak detector. While performing
this task, a visual inspection of the electrical system can
also be done. Check to make sure electrical connections are
secure, the power cord is not damaged and that all the
safety guards are installed properly.
Examine the periphery of the recovery machine;
examine the wheels, casters, and cabinet for damage. Wheels
or casters that do not move freely will at very least be an
annoyance and may cause the unit to tip over. Lastly, protect
the unit when not in use by using a dust cover. Dust covers
not only keep dust from migrating to the internal parts of
the machine, they also protect the machine from inadvertent
bumps in a shop environment.
