Water Supply And Drain Connections - Hoshizaki IM-30CB Instruction Manual

ENGLISH
* Usually an electrical permit and services of a licensed electrician are required.
* If the supply cord is damaged, it must be replaced by a replacement cord available from Hoshizaki Parts/Service Centres.

7. WATER SUPPLY AND DRAIN CONNECTIONS

* 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 0.78 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 the floor drain.
* To prevent a backflow into the storage bin, the outlet hose must be laid as shown.
GOOD
Downgrade
* Be sure to use the new hose-sets supplied with the appliance. Do not reuse any old hose-sets.
1) Attach the free end of inlet hose to the stop valve, noting washer is correctly positioned. Hand
tighten sufficiently to provide leak free joint. It is a wise precaution to have the stop valve within
easy reach.
2) Connect grey flexible outlet hose (accessory) to the fitting on the rear of the icemaker as indicated.
The pipe can be cut to length as necessary to suit position of main drain. To prevent water leaks,
secure the outlet hose to the drain outlet by using a hose band.
Note: Jointing compounds should be approved and suitable for potable water use.
WARNING
Connect to potable water supply only.
