11.1. DISASSEMBLING THE TRANSFORMER-
BOARD UNIT
If you have to disassemble the transformer-board unit,
proceed as follows:
Remove all terminal boards and connectors from the board.
Unscrew the 3 screws from the board and the 2 from the
transformer. Lift the unit up and gently remove the transformer
from the couplings on the board as shown in Fig. 53.
11.2. OIL TOP-OFFS
Periodically check the oil level inside the operator.
A once-a-year check is enough for medium or low usage. For
heavy duty usage, a check every 6 months is recommended.
To access the tank, temporarily remove the plastic oil filler cap
(Fig. 54).
Oil level is visually checked and must cover the copper coil of
the electric motor.
If more oil is needed, add it through the oil filler hole.
Use FAAC XD 220 oil only.
