8.2 Cut-out system
MEDUMAT Standard is fitted with a fusible cut-out
to protect it against internal short circuits.
Changing a fuse
Important note!
In order to prevent damage
to the electronics, avoid all
contact with the printed
circuit board.
1. Unscrew the back panel of MEDUMAT Standard
(6 cross-slotted screws).
2. Remove the defective fuse.
3. Insert a new fuse. Use only officially approved
fuses (see “11. Technical data” on page 58).
4. Replace the back panel and carry out a function-
al check (see “7. Functional checks” on
page 39).
8.3 Adjustment of manometer
When MEDUMAT Standard is switched off and the
valve of the oxygen cylinder is closed, the manome-
ter needle should read exactly “
0“.
Proceed as follows to adjust the needle:
1. Carefully pry off the plastic cover of the
adjustment screw.
2. Adjust the position of the needle by turning the
adjustment screw with a small screwdriver (e.g.
a watchmaker’s screwdriver).
3. Replace the plastic cover.
