SKOPE OD260

Unit Junction

Box

The refrigeration unit connectors and electronic controller are located inside 
the unit junction box.

The box is mounted to the front of the refrigeration unit. The interior can be 
accessed without removing the refrigeration unit, however this will only offer 
restricted access to components. If you need to access other components 
or wiring, remove the refrigeration unit prior to accessing the refrigeration 
unit junction box. 

To open the unit junction box

Condenser

Fan

The condenser fan assembly is made up of a fan blade, a motor and a 
bracket. The motor is attached to the bracket fixed onto the condenser coil 
shroud. When viewed from the inside of the refrigeration unit (motor end), 
the motor and blade should rotate in a clockwise direction and pull air 
through the front of the refrigeration unit.

To replace the condenser fan motor

1. Isolate the chiller from the power supply.

2. Remove the cabinet front kick panel. Take care not to scratch the front 

upstand when removing.

3. Undo the four fixing screws (two at the top and two at the bottom) from the 

front of the unit junction box, and pull the box out from the unit.

4. Undo the four fixing screws (two at the front and two at the back) from the 

unit junction box cover and remove the cover.

5. Service as necessary and refit.

1. Isolate the chiller from the power supply and remove the refrigeration unit 

from the cabinet (see page 33).

2. Remove the LH and RH unit side 

panels.

3. Carefully raise and support the 

evaporator tub to gain access to 
the condenser fan fixing screws.

4. Gain access to the unit junction 

box and trace the condenser fan 
flexible cable to the terminal within 
the unit junction box. Detach the 
condenser fan motor flexible cord 
terminals from the terminal block.

5. Undo the two condenser fan 

mounting plate screws and 
remove the plate and fan as one 
assembly.

6. Detach the condenser fan motor from the motor mount and fit the 

replacement motor.

7. Reassemble the refrigeration unit and test. When reassembling the 

refrigeration unit ensure:

The fan blade is reattached the correct way around.

All wires are attached to the correct terminals within the unit junction box.

The evaporator box is reattached.
