letter until the desired letter appears. Once the entire code is showing on the screen, press the F4 key.
9) Using Assisted Procedure, start a recovery operation (NOTE: the valve under the low pressure filter [Fig. 9-3] should be open).
10) When oil draining is reached, immediately close the valve (Fig. 9-3) under the filter (Fig. 9-5) and turn the machine off.
11) Disconnect the machine from the electrical supply.
12) Disconnect the low pressure quick-connect coupling from the connector (Fig. 9-2) under the filter (Fig. 9-4).
13) Replace the filters. IMPORTANT: The filter replacement must be performed as quickly as possible in order to avoid possible contamination by
moisture in the ambient air.
14) Open the valve (Fig. 9-1) under the filter (Fig. 9-4) and the valve (Fig. 9-3) under the filter (Fig. 9-5).
15) Open both valves on top of the tank.
16) Connect the machine to the electrical supply and turn the machine on. (Leave the rear cover off at this time)
17) Press F1 when the machine displays "INTERRUPTED, F1: TO CONTINUE."
18) Press F2 when the machine displays "ERROR SYSTEM EMPTY."
19) Tank charge about 1 lb (-500g) of refrigerant to charge the machine circuit.
20) While the machine is recovering, use an electronic leak detector to check the seal on the connections that were opened to replace the filters. Re-
tighten if necessary.
21) Turn the machine off and replace the rear plastic cover on the machine. (6 screws)
22) The machine is now ready for normal use.

FILLING THE NEW OIL CONTAINER

It is good practice to fill the oil container whenever the oil level falls below 3.4 oz (100 cc) in order to guarantee that there will be sufficient oil for
topping off during successive operations. Always refer to the information provided by the A/C system manufacturer for oil specifications (oil is not
supplied.)
Remove the new oil container from its holder. Unscrew the container while holding the cap in place. Fill the new oil container with the correct
quantity of oil, of suitable type and grade. Screw the new oil container back on and replace the new oil container in the holder.

EMPTYING THE USED OIL CONTAINER

This operation must be performed whenever the oil level exceeds 6.7 oz (200 cc.)
Procedure: Remove the container from its holder. Unscrew the container while holding the cap in place. Empty the used oil into a suitable container
for used oils. Screw the container back in place while holding the cap in place. Carefully replace the container into its holder. (Dispose of used oil
as per your federal, local and state regulations.)

CHECKING THE SCALE RESPONSE

Turn the unit on and go to the data screen (F3.) Note the Refrigerant Available value. Hang the 500g test weight that was supplied with the machine
from the hook under the scale. (Fig 10-7) The "REF AVAILABLE" should go up by 500g+/-28g, 1.10lb +/-.06lb or 18oz +/-1oz depending on what
units the machine is set at. If the results of the test are not within these specifications, it is recommended that the scale be re-calibrated. The scale
re-calibration should be done by a qualified Service Technician. The equipment necessary for scale re-calibration is not supplied with 69789/69789-
