Section 2 Installation
Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the water to
inhibit scale formation, filter sediment, remove chlorine, and
improve taste and clarity.
Important
If you are installing a water filter system, make sure that
you use a separate line for water-cooled condenser. Filter
life will be greatly reduced if filtered water is used for
water-cooled condenser.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
1. 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.)
2. Water pressure to the machine should be between 1.4
to 5.5 bar (20 to 80 psi).
3. If water pressure exceeds the maximum 5 bar
recommended pressure, obtain a water pressure
regulator from your Welbilt distributor. Adjust pressure
to 2.5 bar (37 psi).
4. Install a water shut-off valve.
5. Connect to a potable water supply only.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to prevent
drain water from flowing back into the ice machine and
storage bin:
1. Drain lines must have a 3.8 cm (1.5 inch) drop of run for
each meter (3 feet), and must not create traps.
2. The floor drain must be large enough to accommodate
drainage from all drains.
3. Run separate bin and water-cooled condenser drain
lines. Insulate them to prevent condensation by
temperature.

INSTALLATION NOTE (SWITZERLAND)
The connection to the drinking water network must be made
with a certified backflow preventer type EA (EN13959) and
with a certified connection hose (EN13618 or EN61770) on
site.
