ENGLISH

[e] STACKING THE CONDENSER UNIT

1)Secure the lower condenser unit to the Legs with eight bolts.

2)Remove the Top Panel of the lower condenser.

3)Place the upper condenser unit on the top of the lower.

4)Secure the upper condenser unit with the four screws from the Top Panel of the lower condenser.

5)Install refrigerant lines, and make electrical connec- tion for each Fan Motor as shown in Items [c] and [d].

8.WATER SUPPLY AND DRAIN CONNECTIONS

-See Fig. 11

WARNING

To prevent damage to the pump assembly, do not operate the icemaker when the water supply is OFF, or if the pressure is below .7 bar. Do not run the icemaker until the proper water pressure is reached.

•Only potable water should be used for the icemaker supply.

•Connection to the water services should be done by a professionally qualified person.

•Water supply inlet is 1/2" female pipe thread (FPT).

•A water supply line shut-off valve and drain valve should be installed. A ball valve is recommended for the shut- off valve. A type of valve other than a ball valve should not have a minimum opening smaller than the water supply line ID as this can cause a reduced water flow rate which can lead to poor defrost performance

and/or freeze up. A minimum of 13 mm. OD copper tubing is recommended for the water supply lines.

•Water supply pressure should be a minimum of .7 bar and a maximum of 8 bar. If the pressure exceeds 8 bar, the use of a pressure reducing valve is required. Do NOT throttle back the supply tap.

•Drain outlet for icemaker dump and storage bin is 3/4" FPT. The drain for condensation is a 10 mm. ID pipe. The icemaker drain and the condenser drain piping connections must be made separately from the bin drain. The sump drain should be vented to insure an adequate flow rate during the harvest cycle. (See Fig. 11).

•Do NOT use solder type fittings as the application of heat to the icemaker/bin may result in damage to the internal connections.

•The drains must have 2 cm. fall per 30 cm. on horizontal runs to get a good flow.

•The drains should not be piped directly to the sewer system. An air gap of a minimum of 5 vertical cm. should be between the end of the drain pipe from the icemaker or the ice bin and the floor drain. (See Fig. 11).

•This icemaker should be installed in accordance with applicable national, provincial and local regulations.

•In some areas, a back flow preventer may be required in the cooling water circuit.
