COMPONENT TECHNICAL DATA
CONTROL TRANSFORMER
Hoshizaki Flaker units include a 24 volt control transformer.
This transformer has a 115 volt primary and 24 volt
secondary and is protected by a 1Amp control fuse. (The
DCM has a dual output secondary of 10.5/24V) The 24 volt
secondary supplies power to the solid state timer board,
relay coils, inlet water valve and flush timer circuit. The
flush valve will be either 24 volts AC or DC, depending on
the model. A rectifier is provide in the flush valve circuit to
convert to DC. Without control voltage on pins 1 and 2, the
timer board will not allow the unit to start.
GEAR MOTOR PROTECTION
The auger gear motor circuit includes two overload safeties.
The primary safety is a manual reset, current type
protector or slow blow fuse located in the control box. This
is a time delay protection which operates if high amp draw
occurs. The secondary safety is a thermal protector which
is incorporated into the gear motor windings.
The current type gear motor safety has been replaced
with a slow blow fuse on most models. The Fuse provides
more consistant protection in low voltage applications.
GEAR MOTOR PROTECTION:
MODEL
PROTECTION
F-300B & F-500B Current type protector
Later production uses a 1.5 amp fuse.
F-450M, F-800 1.5 Amp fuse
F-1000M
Current type protector
Later production uses a 1.5 amp fuse.
F-1000M_F-C 2 amp fuse.
F-1001M_H 3 amp fuse.
F-2000M_F Current type protector.
F-2000M_H 10 amp fuse.
Note: Some cases require a 2 amp fuse for the F-1000M.
Gear motor failure can be expensive and it is very important
to find the cause of the failure when it is replaced.
There are several possibilities for the cause of gear motor
failure. The following check list is designed to help you find
the reason your failure occurred.
