Your new RHS 700 station represents the latest in equipment for servicing airconditioning units (A/C units). The station is designed for refrigerants R12 and
R134a. It can, and must, only be used for one of these refrigerants.
RHS 700 is a test, recovery/recycling-(draining/cleaning), evacuation, oil/refrigerant charging station and is thus able to perform a total process cycle in
servicing A/C units for the automobile industry.
The recycling process is designed to follow SAE-standards J1989 and J2099 on
recycled refrigerant for A/C units.
Process operations - from test to charging - are performed by operating four
different process switches and two shut-off valves. This reduces the risk of error
operation to a minimum.
Constant monitoring ensures that the automatic process sequence does occur
correctly. Safety devices are built into the station to stop operation and indicate
faults in processes, e.g. excessively high pressure, overcharging of charging
cylinder.
During the recycling process a small quantity of oil is drained from the A/C unit.
On completion of the recovery process this quantity can be drained into a
measuring beaker. The same quantity of new oil must be filled into the A/C unit.
Refer to the A/C unit instructions and use only the type of oil specified.
The filter driers have a very high capacity (200 kg) and are easy to replace during
servicing.
A system built into the station ensures that non-condensable gases are automatically blown off and that the discharge of refrigerant to the atmosphere is kept to
a minimum.
Before using RHS 700, read these instructions carefully to ensure that the processes are performed correctly.
1. Always wear protective goggles and gloves when working with
refrigerant.
2. Do not allow refrigerant to come into contact with the skin or eyes.
3. Before disconnecting RHS 700 from the A/C unit, make sure that the
process is completed so that refrigerant does not escape to the atmosphere.
4. RHS 700 is for use only in dry indoor surroundings.
5. Disconnect the electrical supply before performing maintenance on RHS
700.
6. To reduce the risk of fire, avoid using an extension cord. If, however, an
extension cord is necessary, it must have a minimum cross-sectional area
of 2.5 mm2.
7. In the event of fire, remove any external refrigerant cylinders.
8. When oil which accompanies the refrigerant drained from the A/C unit is
tapped from the suction accumulator into the measuring beaker supplied,
ensure that it is handled according to existing national legislation. A
suitable container can be obtained from the refrigerant supplier.
9. Always brake the two front wheels of the station when parking.
10. Most national legislation forbids the station being used for the charging
of cylinders which are intended for transference to a third party.
