Removing insulation shells

Warning:

Risk of spillage. Make sure the draining procedure (see "Draining the coolant circuit", page 26) has been performed.

5. Disconnect the two open type quick couplers from the refrigeration Unit. Perform the steps shown below for both quick coupler

connections.
a) Using a screwdriver, open the clip to unlock the coupler (image 10-4).
b) Remove the coupler from the pump

fi

tting (image 10-4).

Use a cloth or towels to catch spillages before plugging the couplers using the service kit plugs and caps.

c) Close the clip of the coupler (image 10-4).
