3 hoses have to be connected to the evaporator : 

- 

Suction pressure hose

: from the CRP valve outlet 

(

∅

16 – module 12) to the compressor. 

- 

Liquid line hose

: from the expansion valve 

through the heat exchanger (

∅

8 – module 6) to the 

host unit. 

- 

Hot gas line

: from the defrost element inlet  

(

∅

8 – module 6) to the host unit. 

 

  

1.  Run hoses and harness through the hole. 

- Suction line 
- Liquid line 
-  Hot gas line 
-  Fan motor wires 
- RAT cable 
-  Injection valve if so equipped 

2.  Prepare hoses as described in section "Unit hoses /
