Water Supply And Drain Connections - Hoshizaki FM-1000AKE Notice D'installation

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.
* Water supply pressure should be minimum 0.05 MPa (0.5 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 storage bin and the floor
drain.
* 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 flexible inlet hose (accessory) to the
G3/4 fitting on the rear 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 hose can be cut to length as necessary to suit position of
main drain.
[Water-Cooled Model]
* 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.
[a] Standard connections according to WRAS regulations in U.K.
* When selecting a cooling tower, refer to the following peak values of heat flow in the condenser:
