Replacing the hot gas valve
Removal:
1. Disconnect power, water line, and drain line. If a drain
pump is used, it will need to be disconnected and
removed.
2. Remove the access panel and rear panel.
3. Remove the grille by removing the two screws and
disconnecting the three wires to the rocker switch. Be
sure to mark where these wires go for re-assembly.
4. Remove the drain valve.
5. Remove the water valve.
6. Take out the two screws that secure the top of the
electrical bracket located in the front of the
mechanical area.
7. Remove six screws on the bottom of the unit to slide
out the mechanical.
8. Gently slide the mechanical out the rear of the unit
just enough to gain access to the hot gas valve and
drier assembly.
9 Install system access valve(s) and recover
refrigerant. After recovering, be sure to cap off the
access valve to prevent contamination of the system.
10.Disconnect the wires at the solenoid, remove the
solenoid-retaining clip, and remove the solenoid.
11. Un-braze the brazed union upstream of the hot gas
valve. Be sure to cap off after tubing has cooled.
12.Un-braze and remove the capillary tube from the drier
assembly.
13.Un-braze the drier assembly at the end of the
condenser. Be sure to cap off after cooling.
Installation:
1. Bend hot gas valve tubing similar to one being
replaced. Do not kink tubing or overstress tubing at
valve joints.
2. Braze in new drier assembly and then the capillary
tube.
3. Apply a heat sink or a damp cloth on the valve body
to keep heat away. Failure to keep the valve body
cool will result in a leaky valve.
4. Braze the hot gas valve tube (from the side of the
valve) into the tee on the drier assembly.
5. Braze the hot gas valve tube (from the bottom of the
valve) into the evaporator bypass tube.
6. Cool the brazed joints with damp cloth.
7. Remove the heat sink or damp cloth from the valve
body.
8. Check for leaks using dry nitrogen gas and a leak
detection system.
9. Flush the system and recharge.
10.Reassemble reversing steps 1 through 10.
Replacing the Evaporator:
1. Disconnect power, water line, and drain line. If a drain
pump is used, it will need to be disconnected and
removed.
2. Remove the door from the front of the unit.
3. Remove the escutcheon panel.
4. Remove the grid-cutter
5. Remove the ice deflector.
6. Remove the reservoir.
7. Remove the circulation pump , hose, and distributor.
8. Remove the stainless steel evaporator thermistor
fastened on the bottom of the evaporator with a
stainless hex head or phillips screw.
9. Remove the four screws securing the evaporator
plate.
10.Remove the access panel and rear panel at the rear
of the unit.
11. Remove the bin sensing tube with the bin thermistor
remaining inside it. It is not necessary to remove the
bin thermistor from the sleeve. Remove through the
opening in the rear of the liner.
12.Remove the putty and the water line from the opening
in the rear of the liner.
13.Remove the grille by removing the two screws and
disconnecting the three wires to the rocker switch. Be
sure to mark where these wires go for re-assembly.
14.Remove the drain valve.
15.Remove the water valve.
16.Take out the two screws that secure the top of the
electrical bracket located in the front of the
mechanical area.
17.Remove the six screws that secure the baseplate to
the cabinet on the bottom of the unit.
18.Gently slide the mechanical out the rear of the unit
just enough to gain access to the assembly.
19.Install the access valve and recover refrigerant. After
recovering, be sure to cap off the access valve to
prevent contamination of the system.
20.Remove the cap from the rear of the compressor.
21.Disconnect the PTC starter relay at the compressor
by pulling off. You will not need to disconnect the
three wires.
22.Un-braze and remove the capillary tube from the drier
assembly.
23.Un-braze the hot gas valve tube at the evaporator
bypass tube.
24.Un-braze and remove the drier assembly at the
condenser.
25.Un-braze and remove the suction line at the
compressor.
26.Un-braze the hot gas discharge line at the
compressor.
27.Remove the compressor by removing the two lock-
nuts on the mounting plate of the compressor. Lift the
compressor off of the carriage bolts.
