GENERAL CHECKS BEFORE INSTALLATION
Before the installation make sure that the cabinet is disconnected from the
electrical supply.
GENERAL CHECKS
– electrical enclosure must be disconnected form power supply
– electrical data shown on rating label pasted on air conditioner side must
be guaranteed
– Electrical enclosure must be sized according to air conditioner
dimensions and weight.
– Electrical enclosure must have at least IP54 protection degree
– Internal and external components of electrical enclosure don’t have to
affect the proper installation of air conditioner
– The installation site must be free from excessive dirt, aggressive
ambient conditions and moisture.
– The installation site must be free from hot air flows
– The internal side of electrical enclosure must be free from dirt and
moisture
– The environment temperature must be within the range specified on label
pasted on air conditioner side
– Inside of electrical enclosure there must not be components that could
affect the proper ventilation
– the enclosure positioning with installed air conditioner must be
carefully selected to ensure good ventilation (clearance between the air
conditioner and the near walls must be at least 500 mm in each side).
– Proper disposing of condensate discharge
FITTING
- Make the fixing hole on the enclosure as is shown in the drilling template Deburr all sharp edges to avoid accidental injuries
- Apply the gasket (included in fixing kit) on the back panel of the air conditioner
- Lift the air conditioner by lifting eyebolt and place it near the enclosure wall
- Mount the air conditioner on the electrical cabinet according to the drilling template with M6X16 screws and washers against unscrewing (included in mounting kit)
- Connect the condensate drain pipe as is shown in picture below
Air conditioner is fitted with condensate evaporator. Condensate is collected into a vessel and it is warmed by the hot discharge compressor pipe. If condensate rises over a certain level, it is evacuated by over flow pipe
- Air conditioner produces condensate because the moist air inside of the enclosure meets cold heat exchanger (evaporator) and then it becomes water; water production decreases during air conditioner working because enclosure air becomes dry.
- The enclosure must be at least IP 54 protected, if enclosure is not airtight, condensate production could increase.
- Installation of a door limit switch can reduce condensate production when the door is open. (see 3.3.2 Digital input)
- The enclosure IP54 degree is guaranteed only if the air conditioner is proper mounted.

picture
Cable section must be at least 1,5mm2
The male plug is fitted with spring terminals:
- Push the spring with a screwdriver and then insert the wire.
- Check the proper wire insertion.
- Connect the unit with the power supply
Electrical data shown on rating label pasted on air conditioner side must be
guaranteed Install the delayed fuse recommended on rating plate pasted on air
conditioner side to protect the line and enclosure components against short-
circuit.
Upstream of the electrical connection, an efficient disconnection system must
be provided and it must be clearly identified Air conditioner is already
fitted with a temperature controller, no additional temperature control must
be connected upstream of the unit.
Insert signal connector (included in installation kit, refer to picture below) inside of 4 poles female connector placed on the back of the air conditioner.
ALARM OUTPUT / DIGITAL INPUT
Air conditioner is fitted with an electronic controller which permits alarm
output and digital input signals.
Alarm output
Alarm output is activated according to alarm parameters (for example in case
of enclosure temperature higher than ALU value, digital input not activated…
See PARAMETERS at 4.2
DIGITAL THERMOSTAT INSTRUCTION section)
Alarm output is a potential-free contact.
Digital input
WARNING: proper functions of air conditioner are allowed only if digital
input is activated. (closed contact between poles 13-14).
Digital input can be a door limit switch or a generic external clean contact.
Plug for signals is factory wired with a bridge between 13-14 poles. Bridge can be removed to wire, for example, a door limit switch.
STARTING AND ADJUSTMENT
After finishing assembly of the conditioner, wait approx. 30 min. before
starting it (the oil must collect in the compressor to ensure lubrication and
cooling).
The air conditioner operates automatically, that is to say, after insertion,
the evaporator fan operates continuously making the air inside the cabinet
circulate. This way a uniform distribution of temperature inside the cabinet
itself is attained. The built-in thermostat drives compressor and condenser
fan according to set point value.
Compressor turns and condenser fan ON when internal enclosure temperature
rises up to set point value + hysteresis.
Compressor and condenser fan turn OFF when internal enclosure temperature
decreases below set point value.
DIGITAL THERMOSTAT INSTRUCTION
WARNING: the air conditioner is designed to operate at 35 ° C cabinet temperature. If the set point is changed the performance of the unit will vary.
- Regulating thermostat is fixed on side of air conditioner.
- Thermostat could be set into a range from 20°C up to 50°C. Follow thermostat instructions for parameter changing.

PARAMETERS
Regulation
-
Hy Differential: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point.
Compressor
Cut IN is Set Point + differential (Hy). Compressor Cut OUT is when the temperature reaches the set point. -
Ot Thermostat probe calibration: (-12.0÷12.0°C; -120÷120°F) allows to adjust possible offset of the thermostat probe.
-
AC Anti-short cycle delay: (0÷50 min) minimum interval between the compressor stop and the following restart.
-
CH Type of action: CL = cooling; Ht = heating.
-
rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows decimal point display.
-
dLy Display delay: (0 ÷20.0m; risul. 10s) when the temperature increases, the display is updated of 1 °C/1°F after this time.
-
IdF Interval between defrost cycles: (0÷120h) Determines the time interval between the beginning of two defrost cycles.
-
MdF (Maximum) length for defrost: (0÷255min) (0=no defrost) When P2P = n, (not evaporator probe: timed defrost) it sets the defrost duration, when P2P = y (defrost end based on temperature) it sets the maximum length for defrost.
-
ALU MAXIMUM temperature alarm: (SET÷110°C; SET÷230°F) when this temperature is reached the alarm is enabled, after the “ALd” delay time.
-
ALL Minimum temperature alarm: (-50.0 ÷ SET°C; -58÷230°F when this temperature is reached the alarm is enabled, after the “ALd” delay time.
-
i1P Digital input polarity: oP: the digital input is activated by opening the contact; CL: the digital input is activated by closing the contact.
-
i1F Digital input configuration: EAL = external alarm: “EA” message is displayed; bAL = serious alarm “CA” message is displayed. PAL = pressure switch alarm, “CA” message is displayed; dor = door switch function; dEF = activation of a defrost cycle; AUS =to switch on the second relay if oA1 = AUS; Htr = kind of action inversion (cooling –heating); FAn = not set it; ES = Energy saving.
-
did (0 ÷ 255 min) with i1F= EAL or i1F = bAL digital input alarm delay: delay between
the detection of the external alarm condition and its signalling.
with i1F= dor: door open signalling delay
with i1F = PAL: time for pressure switch function: time interval to calculate the number of the pressure switch activation. -
PbC Type of probe: it allows to set the kind of probe used by the instrument: PbC =PBC probe, ntc = NTC probe.
-
dP3 Third probe display- no available
-
.dP4 Fourth probe display- no available
DIGITAL INPUT (ENABLED WITH P3P = N)
The free voltage digital input is programmable in different configurations by
the “i1F” parameter.
Door switch input (i1f = dor)
It signals the door status and the corresponding relay output status through
the odc parameter:
no= normal (any change);, Fan= fan OFF; CPr= Compressor OFF, F_C= Compressor
and fan OFF.
Since the door is opened, after the delay time set through parameter did, the
door alarm is enabled, the display shows the message dA and the regulation
restarts is rtr = yES. The alarm stops as soon as the external digital input
is disabled again. With the door open, the high and low temperature alarms are
disabled.
Digital inputs polarity
The digital input polarity depends on the i1P parameter.
- i1P=CL: the input is activated by closing the contact.
- i1P=OP: the input is activated by opening the contact
GENERIC ALARM (i1F = EAL)
As soon as the alarm input is activated (for example enclosure temperature
higher than
ALU value) the unit will wait for did time delay before signalling the EAL
alarm message.
The outputs status doesn’t change. The alarm stops just after the alarm input
is deactivated.
SERIOUS ALARM MODE (i1F = bAL)
When the alarm input is activated (for example enclosure temperature higher
than ALU value), the unit will wait for did delay before signalling the CA
alarm message. The relay outputs are switched OFF. The alarm will stop as soon
as the alarm input is de-activated.
