REPAIRS 

    
    

 

1. 

Should an electrical component fail, consult the Factory Service Center to obtain the  

 

 

proper replacement part. 

 
 

 

 

2. 

If refrigerant gas is lost from the machine, it will be necessary to use a refrigeration  

 

 

technician to correct the fault.  Contact the Factory Service Center prior to initiating  

 

 

this action.  

 

 

 

Any  competent  refrigeration  technician  will  be  able  to  service  the  equipment.    The 
following procedure must be used: 

 
 

 

a.  The source of the leak must be determined and corrected. 

 
 

 

b.  The machine should be thoroughly evacuated before recharging. 

 

 

 

 

c.  The unit must be recharged with refrigerant measured accurately by weight. 

 
 

 

d.  For  evacuation  and  recharging  of  the  machine,  use  the  crimped  and  brazed 

charging stub attached to the side of the refrigerant compressor. 

 

 

 

 

The charging stub should be crimped and rebrazed after servicing.  

N

EVER

 

allow 

permanent service valves to be fitted to any part of the circuit.  Service valves may 
leak causing further loss of refrigerant gas. 

 

 

 

 

3. 

The refrigerant compressor fitted to the dehumidifier is a durable unit that should give 
many  years  of  service.    Compressor  failure  can  result  from  the  machine  losing  its 
refrigerant  gas.    The  compressor  can  be  replaced  by  a  competent  refrigeration 
technician.   

 
 

 

Failure of the compressor can be confirmed by the following procedure: 

 
 

 

a.  Establish that power is present at the compressor terminals using a voltmeter. 

 

 

 

b.  With  the  power  disconnected,  check  the  continuity  of  the  internal  winding  by 

using  meter  across  the  compressor  terminals.    An  open  circuit  indicates  that  the 
compressor should be replaced. 

 

 

 

c.  Check that the compressor is not grounded by establishing that a circuit does not 

exist between the compressor terminals and the shell of the compressor.
