Duke AHPO Service Manual

AHPO & EPO PROOFER OVENS

IMPORTANT

In order to protect your oven and proofer lamp bulbs during
shipment, they are packaged separately inside the oven cavity. To
install the bulbs;

• Make sure the power is disconnected at the source.

• Turn the glass cover counter-clockwise to remove it.

• Screw each bulb into a socket and replace the glass cover.

•

There are four complimentary spare bulbs. Put them in a safe
place.

NOTE

For 208 and 240 volt ovens, you should be aware that sets of two
bulbs are wired in series. This means when a bulb burns out, the
adjoining bulb will go out but is not defective. Try a bulb that you
know is good in the socket to be sure you are not replacing a bulb
needlessly.

Ovens rated for 380 or 415 Volts are wired in parallel. Only the burnt
out bulb will not be working. Each bulb that is not working should be
replaced.

Call Duke Manufacturing Co. Service for long life replacement bulbs.
