Installation:
Reverse the removal procedure for installation.
Make certain that the thermistor’s
copper tube is fully inserted into the sleeve.
5.3 Grid-Cutter Transformer
The grid-cutter transformer is used to step down the voltage to the grid-cutter to 12 VAC.
The transformer is on only from the start of a harvest cycle to 35 minutes from the start of
the production cycle. The transformer itself can be checked be applying 120VAC to the
marked 120V (for the hot lead) and COM (neutral lead) side of the transformer and
reading 12V side using a multi-meter.
If no readout is found or readout is below 10VAC, replace the transformer.
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 (see figure 3.3).
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.
Disconnect the hot gas valve solenoid orange and white wires at the solenoid.
6.
Remove the hot gas valve solenoid coil by removing the spring retainer, rotating the
coil 90 degrees, and then lifting up.
7.
Take out the two screws that secure the top of the electrical bracket located in th
front of the unit (see figure 3.4).
8.
Remove the three nuts and carriage blots that secure the bottom of the electrical
bracket and secure the power cord clamp.
9.
Gently slide the electrical bracket assembly to the rear of the unit. The condenser
fan wire leads may need to be disconnected if the bracket does not slide all the way
to the rear of the unit.
10. Mark and remove the four wires to the transformer.
11. Remove the two screws that secure the transformer.
12. Remove the transformer.
Installation:
Reverse the removal procedure for installation. Make certain all wire connections are
secure and the power cord’s ring terminal ground is secured. The spring retainer on the
hot gas valve must be secured and seated properly.
