WEATHER PROOF AIR COOLED REMOTE
CONDENSER

The remote condenser versions of Cubers and
Flakers are similar to the air cooled standard
versions with the only difference of the remote
condenser and, on MC and MF series, of the Fan
Speed Control used to supply power to the fan
motor/s.

Technical specifications

1. Remote air cooled condenser fit on proper
brackets for horizontal and vertical
installation (MV series for vertical
installation only).

Cooling capacity with ΔT 15K is 4,5 KW

on MC 16/16 SHORT, MC 46, MF 56, MV
450 and MV 600; 6,0 KW on MV 800 and
MV 1000; 10,5 KW on MFE 61; 20,5 KW
on MF 83.

2. Fan motor/s 220-240/50-60/1 - 135 Watts

- 0,6 Amps with IP 44 protection (against
liquids and solids) and flow rate of 2150
m³/hr (2 motors on MF 66; 3 motors on
MF 86).

3. On MC and MF series only, an Electronic
Fan Speed Control set to 16 bar. On MV
series a standard ON-OFF hi pressure
control (15÷17 bars).

4. Pre-charged refrigerant lines of 10 meters
length equipped with AEROQUIP quick
connections.

5. Hi pressure safety control (manual reset
type) set to 34 bar on MC and MF series
(in place of the condenser temperature
sensor) and to 30 bar on MV series.

6. Hi pressure control warning light.

Installation of the remote air cooled condenser
and pre-charged refrigerant lines

A. Location considerations:

Select the best available place protected from
dirt/dust.

The weather proof remote air cooled condenser
can be installed indoor as well as outdoor and can
operate under the most different conditions (rain,
wing, snow, etc.)

Use the following formula for planning the location
of the condenser and ice machine.

Location Limits – Condenser location must
not exceed ANY of the following limits

Maximum vertical drop dd of 1 meter between the

icemaker and the remote condenser.

Maximum vertical rise rd of 3 meters.

Physical line set maximum length between
icemaker and remote condenser is 10 meters.

Limit to max. one rise and one drop.

Limit the calculated distance (CD) as per the

Calculation formula to 18 meters.

A = Drop = dd x 6.6
B = Rise = rd x 1.7
C = Horizontal run = hd x 1

CD = A + B + C

B. Unpacking and inspection:

Visually inspect the exterior of the shipping
container; any severe damage should be reported
to the delivery carrier.

Uncrate the remote condenser and pre-charged
refrigerant lines and inspect for any concealed
damage. Notify carrier of any cancealed damage.
Check that the pre-charged refrigerant lines are
intact, not kinked.

C. Remote condenser installation

Install and attach the remote condenser to the
floor or to the wall of the building using methods
and practices conform to the local building
requirements.

Remove the control box cover from the remote
condenser and connect the electrical power line
coming from the unit following the wires colors.

NOTE. Cable connecting the unit to the remote
condenser is at 230 Volts so it is imperative to
have the cable properly protected inside a plastic
or metal tube according to the local electrical
code/standard.

D. Pre-charged refrigerant lines

The set of pre-charged refrigerant lines consists
of the 3/8" O.D. self sealing gas line and 1/4" O.D.
self sealing liquid line both equipped with 1-20"
UNEF AEROQUIP quick connections on MC
16/16 SHORT, MC 46, MF 56, of 12 mm and 8
mm O.D. on MV 450-600 and 14 mm and 12 mm
O.D. on MV 800-1000.

On models MF 66 the pre-charged refrigerant
lines are 1/2" O.D. gas line and 3/8" O.D. liquid
line both equipped with 1-20" UNEF AEROQUIP
quick connections.

On model MF 86 only, 16 mm O.D. gas line and
12 mm O.D. liquid line with AEROQUIP quick
connections too.

Whenever the length of the pre-charged
refrigerant lines are longer then the distance
between the ice maker and the remote condenser

keep the excess portion indoor shaped as a
vertical spiral so to avoid refrigerant trapping.

CAUTION. Each coupling on the pre-charged
refrigerant lines is self-sealed and should be
tightened 1/4 turn more then snug tight.
ALWAYS USE TWO WRANCHES WHEN
TIGHTENING THESE FITTINGS, ONE AS
BACKUP WRENCH TO PREVENT TWISTING
OF TUBING AND POSSIBLE KINKING OR LINE
RUPTURE.

Connect the gas line coupling to the remote
condenser refrigerant fitting (labeled GAS) and to
the refrigerant fitting on the rear side of the ice
machine.
Connect the liquid line coupling to the remote
condenser refrigerant fitting (labeled LIQUID) and
to the refrigerant fitting on the rear side of the ice
machine.

ATTENTION. The inlet of the remote air cooled
condenser (gas) must be always located
above the outlet (liquid) for both horizontal
and vertical installations.

Operating instructions

The remote air cooled condenser versions of
Cubers and Flakers are operating in the same
way as the standard machine.
The only difference is the operation of the fan
motor on MC and MF series as on the remote
condenser versions it is no longer possible to use
the condenser sensor to control the ON-OFF
operation of the same.
In place of the condenser sensor has been
installed an electronic fan speed control (set up at
16 bar by its adjusting screw) and a manual reset
type hi pressure control.
The fan speed control supplies a variable power
to the fan motor so to modulate its speed and
keep to a constant value the discharge pressure.
The hi pressure control is used only as a safety
device to switch OFF the operation of the machine
in case of fan motor failure.
