This icemaker requires an earth that meets the
national and local electrical code requirements.
To prevent possible severe electrical shock to
individuals or extensive damage to equipment,
install a proper earth wire to the icemaker. Turn
off the power supply before any maintenance,
repairs, or cleaning is undertaken.
• This icemaker must have a separate power supply
or receptacle of proper capacity. See the nameplate.
It is recommended that this icemaker be the only
electrical device on its power supply circuit.
• Stacked icemakers should each have a separate
receptacle, but they must all be connected in parallel
to the same single phase supply or circuit with
sufcient ampacity.
• The opening for the power supply connection is
22.2 mm diameter to t a conduit.
• If a power cord is used to provide electricity to
the icemaker in place of the permanent (conduit)
connection, a gland should be installed at the
22.2 mm power supply connection. This gland should
be of the correct size for the power supply cord being
installed. The size of the conductors of this power
supply cord should be suitable for the electrical
consumption of this icemaker.
As the colours of the wires in the terminal box of this
appliance may not correspond with eld supplied
wiring or with the markings identifying the terminals in
your power supply receptacle, proceed as follows:
The wire which is coloured Green-and-Yellow must
be connected to the terminal in the receptacle which
is marked with the letter E or by the symbol or
coloured Green or Green-and-Yellow. The wire which
is coloured Blue must be connected to the terminal
which is marked with the letter "N" or coloured Black.
The wire which is coloured Brown must be connected
to the terminal which is marked with the letter L or
coloured Red.
• Usually an electrical permit and services of a licensed
electrician are required.

To prevent damage to the pump assembly, do
not operate the icemaker when the water supply
is off, or if the pressure is below .7 bar. Do not
run the icemaker until the proper water pressure
is reached.
• Only potable water should be used for the icemaker
supply.
• Connection to the water services should be done by a
professionally qualied person.
• Water supply inlet is 1/2" female pipe thread (FPT).
• A water supply line shut-off valve and drain valve
should be installed. A ball valve is recommended for
the shut-off valve. A type of valve other than a ball
valve should not have a minimum opening smaller
than the water supply line ID as this can cause a
reduced water ow rate which can lead to poor
harvest performance and/or freeze up. A minimum
of 13 mm OD copper tubing is recommended for the
water supply lines.
• Water supply pressure should be a minimum of .7 bar
and a maximum of 8 bar. If the pressure exceeds 8
bar, the use of a pressure reducing valve is required.
Do NOT throttle back the supply tap.
• Drain outlet for icemaker dump and storage bin is 3/4"
FPT. The drain for condensation is a 10 mm ID pipe.
The icemaker drain and the condenser drain piping
connections must be made separately from the bin
drain. The sump drain should be vented to insure an
adequate ow rate during the harvest cycle. (See
Fig. 6).
• Do NOT use solder type ttings as the application of
heat to the icemaker/bin may result in damage to the
internal connections.
• The drains must have 2 cm fall per 30 cm on
horizontal runs to get a good ow.
• The drains should not be piped directly to the sewer
system. An air gap of a minimum of 5 vertical cm
should be between the end of the drain pipe from
the icemaker or the ice bin and the oor drain. (See
Fig. 6).
• This icemaker should be installed in accordance with
applicable national, provincial, and local regulations.

The steps in the start-up/operation sequence are as
follows:
1) 1 Minute Fill Cycle
The unit always starts in the 1 minute ll cycle.
When power is applied to the unit, the water valve is
energized and the ll period begins. After 1 minute
the board checks for a closed oat switch. If the
oat switch is closed the harvest cycle begins. If
not, the unit will not start without adequate water in
the sump. This serves as a low water safety shut
off. The water valve will remain energized through
additional 1 minute cycles until sufcient water
enters the sump and the oat switch closes.
2) 1st Harvest Cycle
The compressor starts, hot gas valve opens, water
valve remains open, and harvest begins. As the
evaporator warms, the thermistor located on the
suction line checks for a 9°C temperature. When
9°C is reached, the harvest is turned over to the
adjustable control board harvest timer which is
factory set for normal conditions. This adjustment
can vary the harvest timer from 1 to 3 minutes. The
water valve closes and the pump motor runs for the
last 50 seconds of harvest.
3) Freeze Cycle
After the timer terminates the harvest cycle, the hot
gas valve closes, and the freeze cycle starts. For
the rst 5 minutes the control board will not accept a
signal from the oat switch. This 5 minute minimum
freeze acts as a short cycle protection. At the end of
5 minutes the oat switch assumes control. As ice
builds on the evaporator the water level in the sump
lowers. The freeze continues until the oat switch
opens and terminates ice production.
4) Harvest Pump Out
When the oat switch opens and signals the
completion of the freeze cycle, the harvest
cycle begins. The hot gas valve opens and the
compressor continues to run. The pump-out timer
starts counting the 10/20 second pump out.
The water pump stops for 15 seconds and reverses,
taking water from the bottom of the sump and
forcing pressure against the check valve seat
allowing water to go through the check valve and
down the drain. At the same time water ows
through the small tube to power ush the oat
switch. When the pump-out timer stops counting, the
pump-out is complete.
The control board allows for adjustment of pump-out
to occur every cycle, or every 2nd, 5th or 10th cycle.
5) Normal Harvest Cycle
The water valve opens to allow water to assist the
harvest. As the evaporator warms, the thermistor
reaches 9°C. The control board receives the
thermistor signal and starts the harvest timer. The
water valve closes and the pump motor runs for
the last 50 seconds of harvest. When the harvest
timer completes its countdown, the harvest cycle is
complete and the next freeze cycle starts.
The unit continues through 3), 4) and 5) sequence
until the bin control senses ice and shuts the unit
down.
Note: If the icemaker does not start or complete
a cycle of operation, contact your nearest
Hoshizaki Distributor for guidance.
