The regson for
the
separate water
inlet
con-
nections is that some instalkions use a
water tower for cooling
the
water used
in
the water cooled condenser and some instal-
'
lationsuse treated water (filtered) for the ice
making inlet water connection. Be sure to
install water line (incoming) tothe
318"
male
flare connection on
the
back of the
unit
that
supplies water
to
the
water regulating valve
inside. The setting of the water regulating
valve from
the
factory should be
240
PSlG
for
R-22
units.
NOTE
Always flush out
water lines before starting unit.
Adjustments, if necessary, should be done
at installation.
'
Provide
a
suitable trapped open drain as
close as possible to
the
area where
the
ice
maker is going to be installed. This may be
an existing floor or a
1-114"
trapped open
drain. Two separate drain lines are required
for air cooled units, one for
the
storage bin
and one for the dump valve drain hose.
An additional separate drain
line
will be re-
)
quired for water cooled units from the outlet
of
the
condenser coil to
the
drain.
Run
all
gravity drain lines with a good fall to
the
open drain.
ALL PLUMBING MUST BE INSTALLED IN
ACCORDANCE
WITH
LOCAL CODES.
NOTE:
ln some cases it may be necessary
to insulate the water supply line and drain
line. Condensate dripping to the floor can
cause serious staining
of
carpets
or
hard-
woods.
WATER LEVEL RESERVOIR
The Float Valve is mounted
in
a fixec
position thru it's mounting bracket to
maintain the proper water level
in
the
water
reservoir. For the
500
series units
the
bracket is mounted
thru
the
top hole
of
the
bracket.

WARNING:
Ice maker
will
not operate prop-
erly when water supply temperature
is
be-
low
50°
F
or
sbove
looo
F.
Water supply
pressure must not exceed
50
PSI.
STARTING THE
UN
IT
After
the
ice cuber has been unpacked and
leveled and
all
plumbing and electrical con-
nections
have
been made, start
the
unit, and
check for proper operation.

DRAIN CONNECTION INSTALLATION
IN-
STRUCTIONS
Taking care not
to
kink or collapse vinyl
tubing at any point, route tubes to any open,
trapped or vented floor drain. Run tubing
to
drain separately. Do
not
tee
any drain hoses
together. Add drain tubing required to reach
b
floor
drain.
A cuber has three separate circuits:
the
water circuit,
the
refrigerant circuit and
the
electrical circuit.
Start checking the water circuit
by
making sure
that
there are not thread
or flare joint teaks, either outside
the
unit or
in
the
compressor section.
Next check
the
water
flow
over
the
evaporator and make sure
that
all
holes
in
the
water distributor are
open, (See Diagram
5)
and
that
there
is no undue splash or
loss
of
water
into
the
ice bin.
Also check to see if
the
float valve is func-
tioning properly and
the
correct water level
is being maintained. Re-adjustif necessary.
