2.1 PRODUCT HANDLING
AIR CONDITIONER IP-ACOW series must be handled in upright
position and protected against accidental tipping over.
Air conditioners IP-ACOW series are fitted with female blind threaded insert to screw male
lifting eye bolts.
The air conditioner handling, when unpacked, can be done thanks to lifting eye bolt.
If lifting eye bolts are not included, please provide an adequate M6 male lifting eye bolt (2)
and screw it inside blind threaded (1) insert placed on top of the air conditioner.
(For .0X version remove the rubber plugs placed on the top of AISI304 cover, they cover
the threaded inserts)
Check the proper fixing of eye bolts before lift the air conditioner.
2.2 GENERAL CHECKS BEFORE INSTALLATION
Before the installation make sure that the cabinet is disconnected from the
electrical supply.

2.3 FITTING
1) Make the fixing hole on the enclosure as is shown in the drilling template
Deburr all sharp edges to avoid accidental injuries

Designation: AIR CONDITIONER FOR ELECTRICAL ENCLOSURE Page 6/16
UMA-CDZ-IP-ACOWM085-00
2) Apply the gasket (included in fixing kit) on the back panel of the air conditioner.
3) Lift the air conditioner by lifting eyebolt and place it near the enclosure wall
4) Mount the air conditioner on the electrical cabinet according to the drilling template with
M6X16 screws and washers against unscrewing (included in mounting kit)
5) Connect the condensate drain pipe like is shown in picture below. (Put some glue on
aluminium pipe before to insert it)
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 IP 54 protected, if enclosure is not airtight, condensate
production could increase.
The enclosure IP54 degree is guaranteed only if the air conditioner is proper
mounted.

CONNECTIO
N
The electrical installation must be carried out by a qualified electrician who
is responsible for compliance with the applicable standards and
regulations.
Wire male plug (included) with an adequate cable as is shown by following picture
Cable section must be at least 1,5mm2
The male plug is fitted with spring terminals:
1) Push the spring with a screwdriver and then
insert the wire.
2) Check the proper wire insertion.
3) 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.

STARTING AND ADJU
STM
ENT
After finishing assembly of the conditioner, wait approx. 30 min. before starting it (the oil
must be collected 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 ON when internal enclosure temperature rises up to set point
value + hysteresis and the minimum interval of two successive switch-on of the
compressor (parameter C2) is elapsed.
Condenser fan turns ON when refrigerant pressure rises up to pressure switch set
Compressor and condenser fan turn OFF when internal enclosure temperature
decreases below set point value.

[3]: After switch between Celsius/Fahrenheit, the temperature set-point of parameter item St automatically adjusts to the
corresponding temperature value of Celsius/Fahrenheit, and the temperature set-points of other parameter items related
to Celsius/Fahrenheit automatically adjust accordingly.
For example, St is set to 0℃, and it will automatically adjust to 32℉ after switch; C4 (calibration value of cabinet sensor)
is set to +8℃,and it will automatically adjust to +20*(8/10)=+16℉.
Suggestion: Switch Celsius/Fahrenheit first, then adjust the value of related parameter items to ensure correct parameter
configuration.

will display St.
2) Press the Set button again to display the parameter value of St, and modify the temperature set-
point by pressing or .
WARNING: temperature which unit starts to work is St+C1. For example: St=31, C1=4 compressor and
condenser fan turn on at 35°C (31°C+4°C)
Parameter adjustment
1) When St shows, press to display Po, and press Set to display 00; at this moment, use the
button or to input the password of administrator menu (55).
2) After inputting the password 55, press Set to display Po. The controller will automatically verify
whether the password is correct.
3) When it passes verification, press or to select parameter items St, Po, C1, C2…… (i.e.
any parameter item of user menu and administrator menu); otherwise, the controller will only stay at
the parameter items St and Po without displaying other parameter items.
4) After selecting the menu, press Set to enter the current menu and set its parameters. Use or
to adjust parameter values, then press Set again to return to menu selection status.
5) Under any parameter setting status, press or press no button for 30 sec to exit parameter setting
and save the current parameter value automatically.
Note: The password of administrator menu is valid for once. After exiting parameter settings by
pressing , correct password must be entered again before adjusting parameters.
View temperature
1) When U1 (temperature display) =00, the controller displays the current temperature of cabinet
sensor.
2) When U1=01, the controller displays the current temperature of evaporator sensor.
(WARNING: no evaporator probe available on air conditioner)
Control output
Cooling:
In normal status:
Refrigeration starts when the cabinet temperature > temperature set-point St + control differential C1, and
the indicated time must elapse between two successive minimum switch-on of the compressor.
Refrigeration stops when the cabinet temperature < temperature set-point St.
In case of cabinet sensor fault,
When A1=0, compressor start and stop time in the mode of “run/stop in a proportional time” is disabled,
refrigeration stops.
When A1=1, compressor start and stop time in the mode of “run/stop in a proportional time” is enabled,
refrigeration performs in cycle according to the set refrigeration start A2 and stop A3 time in the mode of
“run/stop in a proportional time”.
