8.8 Replacing the fuse
TO BE CARRIED OUT BY A QUALIFIED ELECTRICIAN ONLY.
The main power supply incorporates a fuse protection on both the live and the
neutral connections, the locations of the fuses are shown in Figure 2 on page 8.
The main connection plug on the 230v instrument should also be fitted with a
fuse.
The appropriate fuse ratings are as follows:-
Voltage Harrier 15/80
(air cooled)
Harrier 18/80
Refrigerated
120v 15 amp (6.3 x 32mm) 15 amp (6.3 x 32mm)
230v 5 amp (5 x 20mm) 10 amp (6.3 x 32mm)
230v plug 7 amp (1/4” x 1”) 13 amp (1/4” x 1”)
If one or both of the fuses have blown, and the centrifuge is switched on, the
display will not function.
To replace the centrifuge fuse proceed as follows:-
1. Disconnect the power supply at the main plug.
2. Move the centrifuge to gain access to the rear,
3. Release the fuses using a flat head screwdriver. Inspect and replace as
necessary with the correct rating. For 230v model, the plug fuse may also
need to be checked.
NB - If the fuse blows immediately or blows again during normal use, the power
supply should be disconnected and the service engineer called.
