5. Tighten screws to securely hold wires. Be sure not to place wire insulation under screws. See Figure 5.
See Figures 8 - 10 for optional conguration wiring details.
Pay careful attention when making any conversions. Not properly following conversion instructions could cause a short circuit, and lead to
property damage, personal injury, or death. Failures and service calls due to shorted circuits ARE NOT covered by warranty.
STEP #2 - After converting the water heater, place the labels provided in the proper locations.
a. The Qualied Service Technician should ll in the white label with all conversion information in permanent ink. Place the completed label
in an area close to the electric water heater rating label. See Figure 6.
b. To convert from Simultaneous to Non-Simultaneous element operation:
1. Remove the purple wire from the bottom side of the fuse holder and place it in the terminal block slot with the adjoining purple wire.
2. Remove the orange wire from the bottom side of the fuse holder and place it in the terminal block slot with the adjoining orange wire.
3. Remove the gray wire from the bottom side of the fuse holder and place in the terminal block slot with the adjoining gray wire.
4. Remove the brown wire from the bottom side of the fuse holder and place in the terminal block slot with the adjoining brown wire.
If the water heater has been changed from its factory installed
conguration, it is required to place the included conversion
labels as detailed below and to notify the factory of the conversion
with the included envelope. Failure to properly document the
conversion could result in property damage, severe personal
injury, or death.
b. Place the clear warning label that states, “THIS WATER HEATER
HAS BEEN CONVERTED” over the electric water heater rating label
on the water heater. Ensure the original model and serial numbers
remain exposed. See Figure 6.
STEP #3 – The Qualied Service Technician is to ll out the conversion
verication envelope with all conversion information. It is VERY
important that the conversion verication envelope be completely
lled out and sent back to the factory to register the water heater as
converted and continue warranty coverage. NOTE: FAILURE TO DO
SO WILL VOID WARRANTY!
NOTE: It is recommended to keep a copy of the lled in conversion
verication form for your records.
