AHPO/EPO TRANSFORMER KIT INSTRUCTIONS

The transformer used for the low voltage lighting has been changed on the 230/415 volt ovens only. We

found that if operators were to mistakenly install bulbs over the 10W maximum that is specied on the

oven that it could cause a failure of the transformer. To help to prevent this situation from occurring, we
have developed a transformer kit that includes; a new cover with circuit protection, revised wiring diagram
and replacement transformers.

DISCONNECT POWER1.
Remove side panel and disconnect fan.2.

Replace all Bulbs with 10W bulbs provided in the kit.7.
Reconnect power and verify proper operation of the lights.8.
