5. ELECTRICAL CONNECTIONS
WARNING
THIS APPLIANCE MUST BE EARTHED
To prevent possible severe electrical shock to individuals or
extensive damage to the unit, the icemaker must be connected
via the 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 5A and should only be replaced
byaqualied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 wires in the mains lead are coloured in accordance with the
following code:
Green & Yellow = Earth
Blue = Neutral
Brown = Live
6. WATER SUPPLY AND DRAIN CONNECTIONS
WARNING
Connect to potable 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 3500.1 and AS / NZS 3500.2. The dual check valve
(backow prevention) supplied with this unit must be connected
between the main supply outlet and water inlet of icemaker.
* To avoid performance reduction or malfunction caused by scaling, the
water supply should have a hardness of not more than 50 mg/L and
a silica content of not more than 30 mg/L. Otherwise, installation of a
proper water treatment device will be required.
* Water supply pressure should be minimum 0.07 MPa (0.7 bar) and
maximum 0.8 MPa (8 bar). If the pressure exceeds 0.8 MPa (8 bar),
use a pressure reducing valve. Do NOT throttle back the supply tap.
* Tightenthe3/4-1/2nippleintothe1/2”FPTwaterinletttingofthe
icemaker with P.T.F.E tape or a sealing compound approved for potable
water use to obtain a leak free joint.
* The dual check valve must be connected in the icemaker water supply
between the main water supply outlet and the straight connection of
the braided stainless steel inlet hose as shown.
* Be sure to use the new hose-sets supplied with the appliance. Do not
reuse any old hose-sets.
* Ensure rubber tap washers are correctly positioned. Hand tighten the
dualcheckvalveandinlethosesu󰀩cientlytoprovidealeakfreejoint.
6) Route the bin control lead through the hole in the base, then into the
bushing provided. See Fig. 5.
8) Pull up any slack in the bin control lead, then put the bushing attached
to the bin control lead back into the hole in the base.
9) Connect the bin control connector to the side of the control box.
10) Replace the water tank, cube guide, pump motor bracket, pump
motor and float switch in their correct positions. The pump
motor bracket must be attached securely to the back so that the
thumbscrews can be tightened.
CAUTION
Be sure to let the discharge hose pass behind the copper tube
and connect it securely in position. See Fig. 3. Otherwise, the
discharge hose may be caught in the front insulation, leading to
improper results.

[Connection to the drain]
* Water should drain into an open trap.
* Drain lines should not be piped directly to the sewer system. A vertical
air gap of a minimum of 5 cm should be between the end of the drain
pipesfromtheicemakerandtheoordrain.
* The icemaker drain is gravity ow, so ensure drain pipe has an
adequatepitchorfall.Topreventabackowintothestoragebin,the
outlet hose must be laid as shown below.
* The icemaker drain line must be run separately from the storage bin/
dispenser unit drain line.
