Water Supply and Drain Requirements
WATER SUPPLY
Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and remove chlorine odor and taste.
Important
If you are installing a Manitowoc Arctic Pure™ water filter system, refer to the Installation Instructions supplied with the filter system for ice making water inlet connections.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
•Do not connect the ice machine to a hot water supply. Be sure all hot water restrictors installed for other equipment are working. (Check valves on sink faucets, dishwashers, etc.)
•If water pressure exceeds the maximum recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.
•Install a water
•Insulate water inlet lines to prevent condensation.
!Caution
Do not apply heat to water valve inlet fitting. This will damage plastic valve body.
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 inch drop per 5 feet 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 ice machine drain lines. Insulate them to prevent condensation.
•Vent the bin and ice machine drain to the atmosphere. Do not vent the condenser drain on
Cooling Tower Applications
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, 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 (32.2°C).
•Water flow through the condenser must not exceed 5 gallons (19 liters) 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 (43.3°C).
