Hoshizaki IM-240ANE Installation Manual page 8

ENGLISH
* 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 flush" mode is recommended. Contact your local Hoshizaki service agent.
* Water supply pressure should be minimum 0.07 MPa (0.7 bar) and maximum 0.78 MPa (8 bar). If the pressure exceeds 0.78
MPa (8 bar), use a proper pressure reducing valve. Do NOT throttle back the supply tap.
* A plumbing permit and services of a licensed plumber may be required in some areas.
* The icemaker drain is gravity flow, so ensure drain pipe has an adequate pitch or fall.
* 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 storage bin and the floor drain.
* Prevent a backflow into the storage bin.
* On water-cooled model, a back flow 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.

1) Attach the angled end of white flexible inlet hose (accessory) to the G3/4 fitting on the rear side of the icemaker as indicated,
ensuring rubber sealing washer is correctly positioned. Hand tighten sufficiently to provide leak free joint.
2) Attach the other end of inlet hose to the water tap, noting washer is correctly positioned before hand tightening as above. It is
a wise precaution to have a stop valve within easy reach.
3) Hand tighten grey flexible outlet hose (accessory) onto the R3/4 fitting on the rear of the icemaker as indicated, ensuring
rubber washer is correctly positioned to obtain a leak free joint. The pipe can be cut to length as necessary to suit position of
main drain.

* 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.
* Whilst connecting a water-cooled condenser to a mains water (potable) supply will not affect the performance of the machine,
it will most certainly cause a high use/waste of a valuable resource and is not recommended.
* 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.
