E. WATER SUPPLY AND DRAIN
CONNECTIONS
When choosing thewater supply for the ice flaker
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Since water is the most important single ingre-
dient in producting ice you cannot emphasize
too much the three items listed above.
Low water pressure, below 1 bar may cause
malfunction of the ice maker unit.
Water containing excessive minerals will tend to
produce scale build-up on the interior parts of
the water system while too soft water (with too lo
contents of mineral salts), will produce a very
hard flaker ice.
Dark chlorinated or iron-containing water can be
improved through the active carbon filter
If water contains a high level of impurities, it is advi-
sable to consider the installation of an appropriate
water filter or conditioner.
WATER SUPPLY
Connect the 3/4" GAS male of the water inlet fit-
ting,usingthefoodgradeflexiblehosesupplied to
thecoldwater supply linewith regularplumbing
fitting and a shut-off valve installed in an acces-
sible position between the water supply line and
the unit.
If water contains a high level of impurities, it is
advisable to consider the installation of an
appropriate water filter or conditioner.
WATER SUPPLY - WATER COOLED MODELS
The water cooled versions of Ice Makers require
two separate inletwater supplies, one for the
water making the flaker ice and the other for the
water cooled condenser.
Connect the 3/4" GAS male fitting of the water
inlet, using the flexible hose supplied to the cold
water supply linewith regular plumbing fitting
and a shut-off valve installed in an accessible
position between the water supply line and the
unit.
WATER DRAIN
The recommended drain tube is a plastic or fle-
xible hose with 18mm(3/4") I.D. which runs to an
open trapped and vented drain. When the drain
is a long run, allow 3 cm pitch per meter (1/4"
pitch per foot). Install a vertical open vent on
drain line high point at the unit drain connection
to ensure good draining.

WATER DRAIN - WATER COOLED MODELS
Connect the 3/4" GAS male fitting of the con-
denser water drain, utilizing a second flexible
hose to the open trapped and vented drain.
This additional drain linemust not interconnect to
any other of the units drains.
F. FINAL CHECK LIST
1 Is the unit in a room where ambient tempera-
tures are within a minimum of 10°C (50°F)
even in winter months?
2 Is there at least a 15 cm (6") clearance
around the unit for proper air circulation?
3 Is the unit level? (IMPORTANT)
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.
ATTENTION. The use of fully hardened
water (without or nearly without mineral
salts) with electric cable capability of
under 30 μS blocks the flow of low voltage
electricity between the lowest sensors in
the swimming pool and therefore causes
the device to be switched off or to stop
working
