To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Disconnect power from fryer.
Use a crosstip head screwdriver or cordless drill to remove the left side panel.
Remove red cap from solenoid and slide nameplate sideways to release the valve coil (green). A flat blade screwdriver may help.
Remove the spring around the barrel.
Unthread the barrel section of the valve from the nipple on the pump and set aside for reuse.
Use a crosstip head screwdriver, or cordless drill to remove the front control panel.
Disconnect the air solenoid leads, remove the conduit, and discard. Reuse the 90° conduit connectors on the valve and frame bracket.
Apply thread sealant to the nipple and attach ¼ NPT elbow. Apply thread sealant to both ends of 5” nipple and attach it to the elbow.
Thread the existing valve onto the nipple using the port labeled “2”. Mount 90° connector to new valve, along with new conduit .
Conduit may have to be formed by hand to mate with conduit on frame bracket.
Ensure the nipple is angled, to keep the valve positioned above the pump outlet.
Solenoid wiring: Locate wire terminals and wiring harness.
- For 220-240V fryers: Using wire nuts, connect wire #90 to one solenoid wire and connect the other solenoid wire to wire #20 on fryer.
- For 230V CE units: Remove or cut and cap wire #45 with crimp nut. Use crimp nuts to connect wire #90 to one solenoid wire and reconnect the othersolenoid wire to #44.
Relay wiring:
- For 220-240V fryers: cut wires 21 and 77 as close to the relay terminal as possible. Strip the ends, and connect all 4 wires together, wires 91, 92, 27 &77, using a wire nut. Then connect wires 91 and 92 to pump relay as shown in diagram below
- For 230V CE fryers: cut wire 25 as close to the relay terminal as possible. Strip the end, and connect it to wire 91 using a blue terminal (EC02-003). Then connect wire 91 to pump relay as shown in diagram below. Wire 92 is not needed.
Replace control panel and side panel and restore power to the fryer.
