Hoshizaki IM-45NE Instruction Manual page 9

ENGLISH
- 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 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.
GOOD
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.
[Air-Cooled Model]
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) [Except IM-100CNE]
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.
[IM-100CNE]
By means of a suitable spanner or wrench, tighten the 3/4-3/4 nipple (accessory) into the Rc3/4 fitting on the bottom of the
icemaker as indicated. P.T.F.E. tape and/or a suitable sealing compound should be used to obtain a leak free joint.
Note: Jointing compounds should be approved and suitable for potable water use.

[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.
