7. WATER SUPPLY AND DRAIN CONNECTIONS
WARNING
Connect to potable cold water supply only.
* 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 lter 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 ow, 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 oor
drain.
* 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.

1) Attach the angled end of exible inlet hose (accessory) to the
G3/4 tting on the rear of the icemaker as indicated, ensuring
rubber sealing washer is correctly positioned. Hand tighten
sufciently 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 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.
[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 ow in the condenser:
Model FM-600AWKE(-N): 3797 W
FM-480AWKE(-N): 3325 W
