C. Drain (When not re-used).
The recommenden tubes for the condenser
waste line are:
- MAR 56-76 - 3/4" GAS female fitting.
- MAR 106-126 - 12 mm I.D.
- MAR 206-306 - 25 mm I.D.
Water drip tray drain line is 21 m/m I.D. Tube
to be connected with clamp to a 21 m/m hose
barbed fitting for all models.
Waste water line must run to an open trapped
vented drain. If drain is a long run, allow a pitch
of 3 cm per meter.
6. REMOTE AIR-COOLED CONDENSER
AND PRECHARGED REFRIGERANT
LINES INSTALLATION (MAR 306 ONLY)
Use the following for planning the placement of
the condenser relative to the ice machine
Location Limits - condenser location must
not exceed ANY of the following limits:
• Maximum rise from the ice machine to the
condenser is 3 physical meters
• Maximum drop from the ice machine to the
condenser is 1 physical meter
• Physical line set maximum length is 6 meters
• Line set length maximum is 9 meters.
Calculation Formula:
• Drop = dd x 6.6 (dd = distance in meters)
• Rise = rd x 1.7 (rd = distance in meters)
• Horizontal Run = hd x 1 (hd = distance in meters)
• Calculation: Drop(s) + Rise(s) + Horizontal
Run = dd+rd+hd = Calculated Line Length.
Configurations that do NOT meet these
requirements must receive prior written
authorization from Scotsman.
Do NOT:
• Route a line set that rises, then falls, then rises.
• Route a line set that falls, then rises, then falls.
Calculation Example 1:
The condenser is to be located 0.9 meter below
the ice machine and then 3 meters away horizontally.
0.9 mt x 6.6 = 5.94 + 3 = 8.94. This location would
be acceptable.
Calculation Example 2:
The condenser is to be located 4 meters above
and then 3 meters away horizontally.
4 x 1.7 = 6.8 6.8+3 = 9.8.
9.8 is greater than
the 9 maximum and is NOT acceptable.
Operating a machine with an unacceptable
configurationg will void the refrigeration
system warranty.
In a crate, separated by the unit crate are packed:
1. The air-cooled condenser mounted on the
platform base with the electrical junction box,
condenser shround, fan motors, fan protection
grid, fan motor speed, control and the
refrigerant lines connection couplings.
2. One set of pre-charged refrigerant line with
connection couplings on both ends of following
variety. Liquid I.D. 12 m/m - Gas I.D. 16 m/m
- 10 mts length.
The pre-charged refrigerant lines, 6 meters long,
are equipped with self-sealing coupling
connections and can be connected or disconnect
few times without loosing the refrigerant charge.
The electric cord line, approx. 10 meters long,
located on the left side of the unit has to be
connected to the condenser junction box
terminals.
The condenser fan motors are originally wired for
230 V single phase and have the following
specifications:
RPM 1420
WATTS 2x180
AMPS 2x0,80
They operate at 230 V 50 Hz and are controlled
by an Electronic Fan Speed Control set at 16 bar.
A. Location consideration:
1. Limit to 10 meters the lenght of the precharged
refrigerant lines from the ice-maker to the
remote condenser.
2. Maximum vertical rise of 3 meters between
the ice maker and the remote condenser.
3. Best available location, protected from the
extremes of dirt, dust, rain, sun and wind.
B. Unpacking and inspection:
1. Visually inspect the exterior of the shipping
container and any severe damage noted,
should be reported to delivering carrier; and a
concealed damage claim filled subject to
internal inspection with carrier representative
present.
2. Uncrate the remote condenser and pre-
charged refrigerant lines and inspect for any
concealed damage claims, as stated in step 1
above.
3. Check that the pre-charged refrigerant lines
are intact, not kinked, and that there is no
sealed puncture or loss or refrigerant.
