REPLACING THE DRYER FILTERS
Replace the filters whenever the machine gives the service alarm [SERV] during the first ten
seconds of operation or whenever the humidity gauge signals the presence of humidity in the
circuit (inner circle yellow. Before performing any operation, check that the replacement filters
are the same types as those installed on the MACHINE. Then proceed as described below
(ref. fig.12):
1) Disconnect the machine from mains supply.
2) Wear gloves and safety goggles
3) Remove the rear plastic cover.
4) Close the taps of the on-board bottle
5) Close both valves of the internal bottle and the valve [1,fig.12] of the filter [4,fig.12]
6) Connect the L.P. quick coupler to the fitting [2,fig.12] of the filter [4,fig.12]
7) Connect the machine to the power supply
8) Make a recovery phase (note: the L.P. command valve must be open)
9) Once the reading of the pressure is ZERO, close immediately the valve [3,fig.12] of the
filter [5,fig.12] and press Stop or Reset
10) Disconnect the machine from the power supply
11) Disconnect the L.P. quick coupler from the fitting [2,fig.12] of the filter [4,fig.12]
12) Replace the old filters with the new ones, paying attention at the direction of the
arrows.
CAUTION: Replace the old filter with the new one as quickly as possible in order to
avoid possible contamination with the humidity in the ambient air.
13) Open the valve [1,fig.12] under the filter [4,fig.12] and the valve [3,fig.12] of the filter
[5,fig.12]
14) Open both valves of the refrigerant bottle
15) Mount the rear plastic cover
16) Connect the machine to the power supply, and turn on the machine
17) During the first 10 seconds (when the service alarm [SERV] is displayed),press the
SEL key.
18) Type in the filter code to cancel the alarm (use the + and ARROW keys).
19) Recover about 500g of gas to charge the machine circuit.
20) Switch off the MACHINE
21) Disconnect the machine from mains supply.
FILLING THE NEW OIL TANK
It is good practice to fill the oil tank whenever the oil level falls below 100 cc in order to
guarantee that there will be sufficient oil for topping up during successive operations. Types of
oil: use only synthetic oils. Always refer to the information provided by the system
manufacturer. Procedure: Remove the tank, complete with cap, after disconnecting the quick-
connect coupling on the upper part. Unscrew the cap and fill the tank with the correct quantity
of suitable type and grade oil for compressors. Screw the cap back on, replace the tank, and
reconnect the quick-connect coupling.
EMPTYING THE USED OIL TANK
This operation must be performed whenever the oil level exceeds 200 cc. Procedure: remove
the tank from its lodging and unscrew the container (holding fixed the cap); empty the tank into
a container for used oils, Screw the container (holding fixed the cap) and replace the container
in its lodging.
