GEMD270A
WATER SUPPLY AND DRAIN CONNECTIONS
GENERAL
When choosing the water supply for the ice flaker,
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Water is the most important single ingredient in
producing ice - these three items are very
important.
Low water pressure, below 20 psi may cause
malfunction of the ice machine unit.
Water containing excessive minerals will tend to
produce scale build-up on the interior parts of the
water system while water that's too soft (water
contains too few mineral salts), will produce a very
hard flaked ice.
PLUMBING CONNECTIONS MUST CONFORM
TO ALL APPLICABLE CODES
CONNECT TO POTABLE WATER ONLY
The model GEMD270A is capable of having water
connections through the bottom base or through
the rear bottom side of the machine. In this second
case it is necessary to remove the small panel at
the bottom rear.
WATER SUPPLY
Connect to the ¾" male water inlet fitting, using the
supplied fitting, to the cold water supply line. A
shut-off valve should be installed in an accessible
position between the water supply line and the
unit.
If the water contains a high level of impurities,
consider installing a water filter or conditioner.
WATER DRAIN
The recommended drain tube is a copper, rigid
plastic or reinforced flexible tubing (supplied) with
.75" (19mm) I.D. which runs to an open trapped
and vented drain. When the drain is a long run,
allow1/4" drop per foot.
Note: Although soft, easily kinked vinyl tubing is
not recommended for a drain, a short length of ¾"
ID vinyl tubing is required to connect a rigid drain
tube to the 20 mm (25/32") fitting on the back of
the GEMD270A.
Install a vertical open vent on the drain line high
point at the drain connection to ensure good
draining.
The ideal drain receptacle is a trapped and vented
floor drain.
NOTE: The water supply and the water drain
must be installed to conform with the local
code. In some case a licensed plumber and/or
a plumbing permit is required.
