[a] Standard connections according to WRC regulations in U.K.
(Fig. 6 and 7)
* When selecting a Cooling Tower, refer to the following peak values
of heat flow in the Condenser:
Model IM-25/30/45W:
IM-65W:
IM-00/30W:
IM-240W:
* Pipes between the Cooling Tower and the icemaker should be at
least 20 mm DIA to reduce pressure loss, even though the icemaker
fittings are 13 mm DIA.
* Pressure loss in the water circuit inside the unit will be 5 to 6 m when
the cooling water flows at the ratio of 4 to 5 lit/min.
* Select a Circulating Pump referring to the above values of heat flow.
* Do not use a Cascade Pump, or the Water Regulator will vary the
flow and stop it during the defrost cycle.
* The Strainer must be cleaned periodically.
[Icemaker Connections]
1) Attach the angled end of white 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 (Fig. 5), noting
washer is correctly positioned before hand tightening as above.
Note: If filtration or treatment is used, ensure icemaker section only
is on treated water supply, not the Condenser.
3) Attach grey flexible outlet hose (accessory) to the R3/4 fitting on
the rear of the icemaker as indicated, confirming fitment of rubber
washer before finally hand tightening the joint. This pipe can be
cut to length as necessary to suit position of main drain (Fig. 3).
4) By means of a suitable spanner or wrench, tighten the /2-3/4
nipples (accessory) into the Rc/2 fittings on the rear 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.
5) Connect the Condenser cooling circuit to the free ends of /2-3/4
nipples as indicated (Fig. 6), using a suitable rigid type pipe. P.T.F.E.
tape and/or a suitable sealing compound should be used to obtain
a leak free joint.

II. OPERATING INSTRUCTIONS
. This icemaker is designed to produce and store edible ice.
To keep the icemaker hygienic:
* Wash your hands before removing ice. Use the Plastic
Scoop provided (accessory).
* The Storage Bin is for ice use only. Do not store anything
else in the Bin.
* Clean the Storage Bin before use (see "III. . CLEANING").
* Keep the Scoop clean. Clean it by using a neutral cleaner
and rinse thoroughly.
* Close the Door after removing ice to prevent entrance of
dirt, dust or insects into the Storage Bin.
2. The use of any electrical equipment involves the observance
of some fundamental rules. In particular:
* Instances of high humidity and moisture increase the risk of
electrical short circuits and potential electrical shocks. If in
doubt, disconnect the icemaker.
* Do not pull the power cord in order to disconnect the
icemaker from the feed network.
* This appliance is not suitable for unsupervised use by
young children or aged or infirm persons.
3. All parts are factory-adjusted. Improper adjustments may
result in failure.
4. If the unit is turned off, wait for at least 3 minutes before
