* 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 storage bin and the floor drain.
* Prevent a backflow into the storage bin.
* 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 white flexible inlet hose (accessory) to the G3/4 fitting on the rear side 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.
4) On water-cooled model, connect the condenser cooling circuit to the Rc1/2 fittings on the rear
of the icemaker as indicated using a suitable rigid type pipe.
