INSTALLATION

2.1 PRODUCT HANDLING
AIR CONDITIONER IP-ACIW series must be handled in upright position and protected against accidental tipping over.
Air conditioners IP-ACIW 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
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.

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

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

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.

ELECTRICAL CONNECTION

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 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 and condenser fan turn 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.
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.

Set-point adjustment

1. Press the Set button for 3 sec in status of measuring and controlling to enter user menu, the panel will display St.
2. Press the Set button again to display the parameter value of St, and modify the temperature setpoint 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”.
