Water Service/Drains
Drinking Water Supply
According to the local water quality, determine whether it
is necessary to install a water treatment system to avoid
the formation of sediment and to filter out impurities and
remove the smell of bleaching powder.
Important
When installing a Manitowoc water filtration system,
be sure to follow the instructions provided with the
filtration system for pipe installation.
Follow these guidelines to install the water inlet lines:
1. Water temperature must be between 50 °F (10 °C)
and 90 °F (32 °C). 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 20
to 80 psi (140 to 550 kPa).
3. The minimum inner diameter of the pipe is 1/2"
(15 mm).
Drain Connections
• Drain lines must have a 1.5 inch (3.8 cm) drop of run
for each meter (3 feet), 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 by
temperature.
• Install a tee to vent the ice machine drain to the
atmosphere.
• Appropriate air gaps must be installed for all drain
terminations as per the applicable specifications.
