2)  Air  supply  shall  be  unobstructed  minimum  12”;  air  return  shall  be 

unobstructed minimum 6”. 

3)  There  is  a  gravity  drain  system,  so  the  unit shall  be  installed  level  or  with  a 

slight  slope  downward  the  drain  connection  and  the  drain  line  shall  be 
installed slope down toward the drain.  
If rise-up is necessary, a condensation pump must be used. 

 

4.  Condensing Unit Location 
 

 

 
 

CAUTION 

Low  ambient  condition  kit  is  required  if  the  temperature  will  be 
below 50

°

F.

 

 

1)  Place  the  condensing  units  WM-250~450SCUR  in  a  properly  ventilated 

location. Otherwise, heat exhausted by the condensing unit will build up and 
the cooling system will not operate properly.  

2)  Condensing unit shall be elevated to avoid possible flooding and shaded from 

direct  sun.  It  shall  not  be  exposed  to  temperatures  higher  than  110  °F  or 
lower than 50 °F. 

3)  Leave minimum 5 ft clearance for the air exhaust side and leave minimum 1 

foot clearance for the air intake side. 

 

5.  Refrigeration Piping and Leak Testing 
 

NOTE 

The  line  connector  sizes  of  liquid  filter  and  indicator,  the  valve 
connector  sizes  of  condensing  unit  or  the  line  connector  sizes  of 
evaporator unit may not be the same as the listed refrigeration line 
sizes. 
If  the  condensing  unit  is  installed  above  the  evaporator  unit,  use 
the suction line one size smaller. 
Expansion  and  solenoid  valves  have  been  installed  on  the  liquid 
line in the evaporator unit.
