Safety
precautions:
Never
refill any tank with more than 80% of its capacity with refrigerant gas. It can
expand and explode
Failure
to follow these instructions could result in personal injury and or equipment
damage.
This
equipment contains electrical components that may cause arcs or sparks and
should be used in a well ventilated area (Ref. National electrical code). This
equipment must not be used in a building with gasoline dispensing equipment or
within three feet of a lubricant pit.
Always
wear safety goggles when operating the recycling center, or handling
refrigerants.
Remove
suction separator bowl “SLOWLY”. Accumulated oil may contain some residual
refrigerant which may boil rapidly.
Use
of an extension cord is not recommended. If an extension cord is used, it should
be a grounded No. 16 AWG minimum.
Never
put refrigerants in a cylinder or tank unless it is a Department of
Transportation approved for refilling. D.O.T. approval is indicated by D.O.T.
4BW or D.O.T. 4BA stamped on the tank.
The
removal of internal fittings and filters can cause refrigerant under pressure to
be expelled. Use care and always wear safety goggles.
Never
perform maintenance on or remove panels from the machine without disconnecting
the 110 volt power cord.
Any
recycled refrigerant tank that has been stored or transferred must be
tested for non-condensable gases prior to use.
The
recycling center is designed for R12 refrigerant gas.
Equipment
is designed to operate in a temperature range of 50degrees F to 120 degrees F.
Increased oil viscosity may cause pump to stall in lower temperatures.
Refer
repair service to qualified personnel.
Obtain
certification before servicing automotive air conditioning systems.
PREPARATION
for USE:
The
reclaim tank must be evacuated prior to first time use or after storage.
Connect
your manifold gauges. Yellow hose goes to the port on the rear of the recycling
center. Make sure that you have anti-blowback valves installed on your gauge
set.
1.
Reclaim Function
The Reclaim/Vacuum switch activates the reclaim
function of the recycling Center. In this function, the refrigerant is removed
from the vehicle system and stored in the refillable tank on the reclaimer. As a
zero gauge reading is approached, the reclaimer goes into a recovering residual
refrigerant mode- the pump pulls down to a slight vacuum (4”hg.) and shuts off
(the pump). The machine now looks for a slight pressure rise (2 PSI) over a
period of time. If the +2 psi rise in pressure is seen, the pump redstarts and
pulls back down to 4 “HG. This cycle repeats until no rise in pressure is
seen. If the rise is not seen, the unit tells the operator that the recovery
process is complete by flashing the light beside the Reclaim/Vacuum switch
(approximately 3 times a second). This cycle mode is termed the Residual R12
Reclaim Cycle. The length of time that the machine looks for a pressure rise
during residual cycling depends on ambient temperature. The Recycling Center
calculates this automatically. The clicking sound of a solenoid opening and
closing during the reclaim function is normal.
NOTE: The
Reclaim/Vacuum light is used for multiple functions:
1.
to indicate that the Reclaim/Vacuum switch has been turned on.
2.
to indicate that a reclaim function has been completed. (Flashes
continuously about three times a second)
3.
to indicate a problem in the reclaim system. The number of flashes refers
to an error code. See error code page.
The purpose of the vacuum function is to remove air
and moisture from the vehicles A/C system prior to charging. This function is
also used to prepare reclaim tanks before placing them into service.
When the vacuum function is selected, the unit enters
the reclaim mode first reclaiming any refrigerant which may exist. Once all
refrigerant has been removed from the system, the Recycling Center will
automatically perform the vacuum function. The vacuum function will continue for
a total of 30 minutes. The unit tells the operator that the vacuum function is
completed by flashing the reclaim/vacuum light (approximately three times a
second.)
This function allows the operator to transfer
refrigerant from the Recycling Center to the vehicles A/C system for leak
testing.
NOTE: The
first time you use the recharge capabilities on this equipment you may not be
able to charge all the refrigerant which was reclaimed. Your Recycling Center
will maintain a small amount of refrigerant in the reclaim tank at all times
(approximately 3-4 pounds). This eliminates the possibility of charging
non-condensable that may have entered the reclaim tank. No charging is possible
until the “tank empty” light is off.
4.
Non-Condensable Gas Purge Function
In the reclaim mode, if the pressure in the Recycling center exceeds a calculated pressure, the Recycling Center enters a purge cycle. This happens when non-condensable (air) are ingested into the Recycling Center during the reclaim cycle. All function lights on the control panel are turned off except for the power light. After a thirty (30) second delay the reclaimer will vent non-condensable from the reclaim system into a purge bottle (located inside right panel access). The venting of non-condensable lasts for fifteen (15) seconds. During this period of forty-five (45) seconds the reclaim system is venting and allowing pressure to stabilize. A hissing noise is normal and no cause for concern. The Recycling Center will automatically resume normal operation.
Switches
and Indicator Lights
1. Power switch and light
This
switch is used to turn the Recycling Center on and off. The light is illuminated
when the power switch is placed in the ON position.
2.
Reclaim Vacuum switch and light
This switch is used to activate the reclaim or vacuum function. The light has three functions.:
1.
The light
is illuminated when either function is selected.
2.
The light
also flashes continuously (three times a second) to indicate the Reclaim/Vacuum
operation has been completed.
3.
The
Reclaim/Vacuum light is also used when a problem within the refrigerant reclaim
system has been detected. The number of times the Reclaim/Vacuum light flashes
indicates an error message.
3.
Charge/Liquid Switch and Light
Used to activate the charge/liquid function. The
light is illuminated when the switch is placed in the “ON” position.
4.
Tank Full Light “ON” (Change tank)
This light can come on when reclaiming R-12 from a
vehicle A/C system. This indicates that the reclaim tank is filled to the
maximum safe capacity with reclaimed R-12. (NEVER EXCEED 80% of any tanks
capacity). When this light is on, the pump used in the Reclaim/Vacuum cycle will
be automatically turned off. This does not indicate that the vehicle is
completed. The full tank must now be replaced with an empty reclaim tank. See
“RRECLAIM TANK REPLACEMENT PROCEDURE”
5.
Tank Empty Light “ON”
This indicates that there is an insufficient amount
of liquid refrigerant in the reclaim tank for leak testing.
6.
Service Suction Separator Light “ON”
This indicates that the suction separator bowl has
reached its capacity and the float switch has tripped. The bowl should now be
emptied and cleaned in accordance with the procedure entitled “Suction
Separator Maintenance”
More instructions will be made available here and are furnished with a machine that is purchased.
