6.1.  Expansion valve

 

 

 
 

DO NOT TOUCH THE EXPANSION VALVE.

 

 

 

6.2.  Water level

 

 

 

 

The  purpose  of  maintaining  proper  water  levels  is  to  allow  adequate  water  flow  to  the 

evaporator.  A water level sensor has been incorporated to shut off unit until required minimum 

water level is achieved.

 

 

The optimal water level is indicated in diagram below.
