DRAIN CONNECTIONS

Follow these guidelines when installing drain lines to

prevent drain water from flowing back into the ice

machine and storage bin:

• Drain lines must have a 1.5 in. (3.8 cm) drop per 5

ft. of run (2.5 cm per meter), and must not create

traps.

• The floor drain must be large enough to

accommodate drainage from all drains.

• Run separate bin and water-cooled condenser

drain lines. Insulate them to prevent condensation.

• Vent the bin drain to the atmosphere. Do not vent

the condenser drain on water-cooled models.

• Drains must have a union or other suitable means

to allow a place of disconnection from the ice

machine when servicing is required.

COOLING TOWER APPLICATIONS

(WATER-COOLED MODELS)

A water cooling tower installation does not require

modification of the ice machine. The water regulator

valve for the condenser continues to control the

refrigeration discharge pressure.

It is necessary to know the amount of heat rejection,

(refer to page 25) and the pressure drop through the

condenser and water valves (inlet and outlet) when

using a cooling tower on an ice machine.

• Water entering the condenser must not exceed

90°F (32°C).

• Water flow through the condenser must not

exceed 5 gal. (19 L) per minute.

• Allow for a pressure drop of 7 psi (48 kPa)

between the condenser water inlet and the outlet

of the ice machine.

• Water exiting the condenser must not exceed

110°F (43°C).
