5.1 Removing the FCCV

Note: The FCCV will be reused in the replace-
ment coil.  DO NOT discard.

1)  Disconnect the liquid line to remove the FCCV 

from the fitting.  Retain for later installation in 
the new coil.

2)  Using tubing cutters, cut copper tubing on 

either side of fitting that held FCCV.  

3)  Remove fitting from coupling panel. The 

new field fabricated liquid line will be routed 
through this opening.

5.2 Remove the existing coil 

5.3 Installing the FCCV into the 

replacement coil

1)  To install the metering device, remove the 

outer sheet metal cover of the replacement 
evaporator coil by taking out the screws 
around the perimeter of the shield.  

 

This will expose the short liquid line and dis-
tributor assembly of the replacement coil. 

 

Retain the screws for re-attachment in a later 
step (See Figure 2) 

 

Note: Take care not to bend the coil distributor 
lines.  Use a backup wrench to prevent stress 
on components.  (See Figure 3)

2) 

Remove the short liquid line from the new coil 
distributor. (See Figure 4)

3)  Install the FCCV into the distributor assembly 

with orientation as shown. (See Figure 12)

4)  Bolt the short liquid line to the distributor as-

sembly. (See Figure 3)

Note: Torque specification for TEV equals 1/6 
turn past finger tight.
