When the condensing unit operates for more than
one icemaker, install a ball valve on the liquid line
and suction line.
1) If suction pressure of the condensing unit
exceeds 0.10 MPa (1.05 bar), remove the EPR
(evaporating pressure regulator) from the suction
line. See Fig. 8.
Fig. 8
Close-up
Remove EPR
2) To ensure the most efficient ice making
capacity (10/10°C), set the icemaker as below.
For details, refer to the specifications on the
dimensional drawing.
Suction pressure: 0.10 MPa (1.05 bar)
Evaporating temperature: -24°C
3) While the icemaker is running, check whether
suction pressure of the condensing unit
and evaporating pressure of the EPR are
appropriate.
4) If the condensing unit has an inverter system,
set evaporating temperature to -25°C.
5) Piping length and height of the condensing
unit vary with installation environment and
connection method. Connect piping so that
discharge pressure of the condensing unit will
be 1.32 MPa (13.5 bar) or more. Otherwise,
pressure loss may increase and ice making
capacity may decrease.
6) Lay horizontal piping on the downgrade (1/200).
[c] LIQUID AND SUCTION LINES
1) The icemaker must be connected to the liquid
and suction lines of the compressor system using
two copper tubes of sufficient sizes directed
to the rear of the icemaker for connection to
the pre-tted internal copper tubes. Both tubes
should be insulated separately.
Note:
1. The sizes of the interconnecting pipes between
the icemaker and the compressor system should
be 3/8” OD for the liquid line and 5/8” for the
suction line up to a maximum of 20 m (assuming
a straight run). For each 90° bend, add an
equivalent 0.5 m to the overall pipe length (e.g.
20 m straight pipe + four 90° bends = equivalent
22 m of straight pipe).
2. When using a single compressor refrigeration
unit that is installed in a remote location,
ensure that it is adequately protected against
low ambient temperatures (capacity controls/
crankcase heating), oil return where the
icemaker is below the height of the compressor
(suction risers/oil traps/oil separators) and
liquid refrigerant return where the icemaker is
above the height of the compressor (suction
accumulator). Always check the compressor
manufacturer’s guidelines.

exiblesupplycordsuppliedwiththeicemaker
to an appropriate outlet socket installed in
accordance with local codes and regulations
i.e. AS / NZS 3000.
Disconnect the main power supply before
any maintenance, repairs, or cleaning is
undertaken.
* It is recommended that these appliances are
connected to a separate 240VAC supply,
protected by an appropriate circuit breaker and
Residual Current Device. Check the nameplate
on the icemaker for the supply requirements.
* The main control box fuse is rated at 12A and
should only be replaced by a qualified service
engineer.
* The service of a licensed electrician may
be required to ensure the installation is in
accordance with the local codes and regulations.
* The non-rewirable plug must never be used
withoutafusecoverbeingtted.
* The correct replacement for the detachable fuse
cover is identifiable from the manufacturer’s
reference number stamped on the plug.
* Supply of replacement fuse covers can be
obtained from Hoshizaki Parts/Service Centres.
* The wires in the mains lead are coloured in
accordance with the following code:
Green & Yellow = Earth
Blue = Neutral
Brown = Live
5. WATER SUPPLY AND DRAIN
CONNECTIONS
WARNING
Connect to potable cold water supply only.
* The service of a licensed plumber may
be required to ensure the installation is in
accordance with the local codes and regulations.
[Connection to the water supply]
* The connections to the mains water supply must
be made in accordance with the Plumbing Code
of Australia and in accordance with AS / NZS
3. An electrical link/connection between the
icemaker and compressor system is NOT
necessary. Where a multi compressor rack
system is used, the icemaker’s internal controls
will close the electrically operated solenoid
valves to stop ice production. Where a single
remote compressor is used, this must be tted
with a low pressure safety switch to stop the
compressor at approx. 0.5 bar suction pressure
as the solenoid valve’s closing will result in the
compressor pumping down.
2) After completing all the refrigeration tubing
connections, the pipe work should be leak
tested, evacuated and vapour charged with
R404A. The design pressure of R404A is 31.4
bar (3.08 MPa) at discharge side and 16.7 bar
(1.64 MPa) at suction side.
3) The refrigeration connections are now complete.
Proceed to sections 4 and 5 to continue with
other service connection requirements before
completing section 6, the start-up procedure.
4) Refit the side and top panels in their correct
positions.
