Hoshizaki IM-30CWNE-HC Instruction Manual page 10

* The connections to the mains water supply must be made in accordance with the countries' current requirements of the Water
Supply or Water Fittings Regulations.
* 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 0.8 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.
* A plumbing permit and services of a licensed plumber may be required in some areas.
* The icemaker drain is gravity flow, so ensure drain hose has an adequate pitch or fall.
* 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 the floor drain.
* To prevent a backflow into the storage bin, the outlet hose must be laid as shown.

Downgrade
* 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.
