Vacuum Pump; M.1) Oil Top-Off; M.2) Oil Change; Replacing The Dryer Filters - FLO-DYNAMICS CCST 288 Manual Del Usuario

Close the bottle tap and press START. The machine will stop automatically after having
recovered the residual refrigerant from the hoses. Close the high-pressure tap. Disconnect
the external bottle. Switch the machine off.

VACUUM PUMP

Perform the operations listed below on a routine basis in order to ensure the best operation of
the vacuum pump:
M1) Oil top-off.
M2) Oil change.
When topping-off or replacing the pump oil, use only the oil recommended by the
manufacturer. Flo-Dynamics P/N 90808 is available from your equipment supplier.

M.1) Oil top-off

This operation must be performed when the level of the oil falls to less than half on the indicator
(4) (refer to Figure 10). NOTE: In order to correctly check the oil level, run the pump for at least
1 minute, so that the oil
perform the steps listed below in the order given. Disconnect the machine from the electrical
supply. Locate the oil cap (2) and screw it completely off. Add oil through the hole in which the
oil cap was lodged (2). Add oil a little at a time, waiting for the level to rise before each
successive addition, until the oil level is about ½ cm above the red mark on the indicator (4).
Replace the oil cap (2) and tighten down.

M.2) Oil change

The vacuum pump oil must be replaced every 150 working hours, or when the filter/dryers are
replaced. The oil must also be replaced whenever it changes color due to absorption of
humidity. Before beginning the oil change procedure, obtain an empty 16 oz. (1 pint) or larger
container in which to collect the used oil. The pump contains about 16 oz. (1 pint) of oil. Use
only the oil recommended by the manufacturer. (Flo-Dynamics p/n 90808)
1) Disconnect the machine from the electrical supply.
2) Unscrew the filling cap 2 (refer to Fig. 10).
3) Unscrew the drain cap 3.
4) Allow all the oil to run out into a disposal container (drain clearance < 3.95 inches).
5) Close the drain cap 3.
6) Pour in new oil through the filling hole, opened previously, until the level rises to the
midpoint on the indicator 4.
7) Replace the oil cap 2 and tighten.

REPLACING THE DRYER FILTERS

Replace the filters when the machine alerts you or when the humidity gauge ("c" in Fig. 6)
signals the presence of humidity in the circuit (inner circle yellow). Before performing any
operation, check that the replacement filters are the same type as those installed on the
machine. Then proceed as described below (refer to Fig. 11):
1) Disconnect the machine from the electrical supply
2) Wear protective gloves and glasses
3) Remove the rear plastic cover from the machine.
4) Close the taps on the bottle.
5) Close the tap (1) on the filter (4).
6) Connect the low pressure quick-connect coupling to the male connector (2) of the filter
(4).
