Context

Tools: flat-head screwdriver, welding tool, refrigerant retrieval device (required

based on local conditions), nitrogen injection and pressure preservation tool,

vacuumization tool, and refrigerant injection tool.

Procedure

Step 1 Hold down

on the home screen. Tap Yes on the shutdown confirmation

screen displayed.

Step 2 Open the front door, and turn off the indoor unit circuit breaker and circuit

breaker in the power distribution cabinet.

Step 3 Remove the return air filter.

Step 4 Reclaim the refrigerant.

Step 5 Pry the EEV coil off using a flat-head screwdriver, as shown in

Figure 5-8

Step 6 Weld the two ends of the EEV using a welding torch, as shown in

Figure 5-8

Then, remove the EEV.

Figure 5-8 Removing the EEV

Step 7 Weld a new EEV, and install the coil for the EEV.

NO TICE

Protect the surrounding components during the welding process.

Step 8 Inject nitrogen and preserve the pressure. After checking that the EEV and system

do not leak, perform vacuumization and inject refrigerant.

Step 9 Install the return air filter.
