T
hank you for choosing our refrigerating unit. This model is equipped with a highly evolved electronic control panel that dispenses with a series
of conventional components such as timers, thermostats and thermometers while offering the facility for straightforward personalisation of the
control program to suit your needs. The panel also provides a self-diagnostic function showing the nature of any functional anomalies so that
they can be solved fast. This operation and programming manual has been published to assist you, please read it carefully.
1) OPERATION
The distinguishing feature of this unit is that it is formed of two separate parts: the condensing unit with remote electronic control panel, for instal-
lation outside the coldroom , and the evaporator for installation inside the room. This design solution eliminates problems related to space
restrictions outside the cell. The two units can be installed at a distance from each other. The air is drawn through the evaporator by means of
the motor driven fan and exhausted through the grids on the sides. In the evaporator, the air drawn in by the motor driven fan units is cooled
by the heat exchanger and expelled from the front of the unit. The temperature is monitored by room sensor. Once the set-point is reached the
refrigeration plant is stopped. Defrosting is automatic by means of electrical heaters in the evaporator; this cycle terminates in correspondence
with the "defrost end" temperature set on the control unit and detected by a sensor. The defrost water is collected in a tray located beneath
the evaporator from where it is drained to outside the rooml.
2) INSTALLATION
For correct installation, proceed thus:
1) Position the condenser unit on floor level outside the coldroom.
2) Secure the evaporator unit to the coldroom ceiling (pict. 1) as follows:
2A) Open the fan holder bottom ‘A’ by
loosing screws ‘B’ (pict. 2-3).
2B) Drill the fixing holes on the
coldroom ceiling observing the
recommended distance from the
wall (pict. 4).
2C) Secure the evaporator using the
supplied components (pict. 5):
1 - Threaded bar
2 - Washer
3 - Nut
2D) Hook up the evaporator to the electrical supply utilising the terminal board located inside
the junction box. Close the junction box and clamp the cable so that it is clear of the fan
blades.
2E) Re-close the air-cooler cover and then make the refrigeration connections (pict. 6).
REMOTE CONTROL PANEL INSTALLATION
Unscrew the lateral fixings to remove the remote control panel cover plate (pict. 7).
Fix the base plate in the desired position using the pre-drilled
holes and making sure it is level (pict. 8).
Replace the cover plate by performing the operation indicated at
pict. 7 in reverse.
Adjust the cable connection between the control panel and the
unit, making sure it does not interfere with existing cable
connections.
To assure optimal operation of the refrigerating unit:
A) Restrict the number of times the coldroom is opened.
B) Make sure that the unit has an efficient air intake and expels a generous amount of turbulent air.
C) Position the unit on horizontal planes..
D) Avoid to place the condensing unit in closed ambient or not ventilated.
