C.
Remote condenser - Wall attachment
1. Install and attach the remote condenser to the
wall of the building, using the methods and
practices of building standards that conforms
to and meets the local building code
requirements in your area.
D. Remote Condenser Electrical connection
Connect the electric cable from Remote
Condenser to the terminal board of the machine
as described in the following.
1. Remove jumper from contact 17 and 18 of the
machine terminal board.
2. Connect Remote Condenser BLU wire to
Neutral (N) of machine terminal board.
3. Connect Remote Condenser BROWN wire to
contact n. 18 of machine terminal board.
4. Connect Remote Condenser GREEN/YELLOW
wire to the grounding related screw.
E.
Pre-charged refrigerant lines
1. The set of pre-charged refrigerant lines
consists of a self-sealing liquid line and a self-
sealing discharge line.
One coupling on each line is fitted with a
Schrader valve, which provides the
servicemen with access for refrigerant
evacuation through tubes, refrigerant charging
and service gauges application when
necessary.
2. When possible, route the maximum lenght of
the pre-charged refrigerant lines inside the
building, with the minimum lenght outside, to
prevent vandalism and to minimize the
condenser effect that exposed lines can pro-
duce in cold weather.
Insulate lines that be exposed to outside
temperatures that will be below freezing, for
extended periods of time.
CAUTION - Each coupling on the set of
pre-charged refrigerant lines, the
refrigerant fittings on the remote
condenser and on the icemaker chassis
are self-sealing and should be tightened
1/4 turn more than snug tight.
ALWAYS USE TWO WRENCHES WHEN
TIGHTENING THESE FITTINGS ONE AS A
BACKUP WRENCH TO PREVENT
TWISTING OF TUBING AND POSSIBLE
KINKING OR LINE RUPTURE.
3. Connect the small dia refrigerant line coupling
to the unit fitting labelled "LIQUID" on the right
side of the icemaker chassis.
4. Connect the large dia refrigerant line coupling
to the unit fitting labelled "GAS" on the righ
side of the icemaker chassis.
5. Connect the small dia refrigerant line coupling
with Schrader valve to the condenser fitting
labelled "LIQUID".
6. Connect the large dia refrigerant line coupling
with Schrader valve to the condenser fitting
labelled "GAS".
F. Excess lenght of pre-charged refrigerant lines;
at installations where the icemaker chassis-
to-remote condenser refrigerant line path is
substantially less than the lenght of pre-
charged refrigerant lines to be installed, route
and dress the excess refrigerant line as
follows.
1. Follow straight line routing when possible.
2. Retain excess pre-charged refrigerant line
inside the building.
3. Spiral the excess lenght of the precharged
refrigerant lines in the best selected inside
location and in a manner that prevents
refrigerant trapping.
