[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. This appliance
incorporates backow protection complying with AS / NZS 3500.1.
No further backflow protection is required for connection to the
water supply.
* Icemaking water must be potable water. Where scaling can be
caused by water quality:
- Installation of an external filter or softener is recommended.
Contact your local water treatment professional or Hoshizaki
service agent.
- Change to the “full drain ush” mode is recommended. Contact
your local Hoshizaki service agent.
* 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 proper pressure reducing valve. Do NOT throttle back
the supply tap.
* Attach the angle end of the inlet hose to the G3/4” water inlet fitting on the rear of the
icemaker.
* Be sure to use the new inlet hose-sets supplied with the appliance. Do not reuse any other
inlet hose-set.
* Ensure rubber tap washers are correctly positioned. Hand tighten the inlet hose sufciently to
provide a leak free joint.
[Connection to the drain]
* Hand tighten grey exible outlet hose (accessory) onto the R3/4 tting on the rear of the icemaker as indicated, ensuring
rubber washer is correctly positioned to obtain a leak free joint. The hose can be cut to length as necessary to suit position of
main drain.
* Drain lines should not be installed directly to the sewer system. A vertical air gap of a minimum of 5
cm should be between the end of the drain hoses from the icemaker and storage bin and the oor
drain.
* To prevent a backow into the storage bin, the outlet hose must be laid as shown.
* On water-cooled model, a back ow preventer may be required in the cooling water circuit.
* Be sure to use the new hose-sets supplied with the appliance. Do not reuse any old hose-sets.
Water-Cooled Model:
[Connection to the water-cooled condenser]
* Hoshizaki recommends that the water-cooled condenser should be connected to a closed circuit recirculating type cooling
system utilizing a tower, water chiller or similar. Water make up should be via a ball valve/break tank arrangement.
* The services of a licensed or coded plumber should be used to ensure a correct installation.
* The connections should be made properly in compliance with the applicable national or local regulations.
* When selecting a cooling tower, refer to the following peak values of heat ow in the condenser:
Model IM-240AW: 5235 W
* Pipes between the cooling tower and the icemaker should be at least 20 mm DIA to reduce pressure loss, even though the
icemaker ttings are 13 mm DIA.
