Preface
The Thermolizer is designed for retail bakeries,
in-store bakeries and donut shops. It features two
individual insulating clear acrylic doors with
stainless steel tops, bottoms and ends, to enable
loading and unloading of 3 screens or bun pans
per door. This minimizes heat and humidity loss.
The air is recycled every 18 seconds.
A thorough understanding of how to operate,
clean, and maintain the Thermolizer safely will
prevent production delays and injuries. The
operator must work safely at all times, read and
follow the instructions in this manual, and heed
all warnings, including the following:
•To avoid electrocution or other injury,
turn off the machine’s main power
before attempting any cleaning,
disassembly, adjustment, or repair.
•To avoid damaging the machine, never
use force to assemble, disassemble,
operate, clean, or maintain it.
•Be careful never to get water or other
materials on the floor. If anything does
get spilled on the floor, mop it up
immediately. Materials on the floor can
cause people to slip or fall, resulting in
serious injury or loss of life.
•To prevent unintentional startup and
possible fire, disconnect the machine
from the power source if there is a local
power outage. When the power is
restored, it is safe to connect the
machine to the power source again.
•To avoid electrocution, make sure that
all electrical cords are not frayed or
cracked and that they do not pass
through any water.
•Make sure that all electrical cords are
routed so that no one will trip over them.
•If water is spilled while cleaning the
proofer, be sure to dry the floor
thoroughly.
•The autofill unit must be turned on to
insure water is contained in the water
box. Check often. Use only soft or
distilled water in the operation of this
thermolizer.

1 Operation
Control Functions
A. HUMIDITY CONTROL: This control
is located inside the control box front
panel and can only be adjusted by a
qualified technician. It controls the
water heating element. Set on high, the
water heat element will remain on
constantly. Set on any setting other than
high, the control will cycle on and off.
Higher numbered settings create a longer
on-cycle and high humidity. The factory
setting is 4.5 on the dial.
B. HEAT CONTROL: This control is
located inside the control box front panel
and can only be adjusted by a qualified
technician. It controls the air-heating
element. The factory setting is: place the
dot on the knob at 11:00 to produce 95 -
110F.
C. CONTROL BOX POWER SWITCH:
Controls the power to the control box.
CAUTION
Do not permit water pan to run out of
water. Check often. Use only soft or
distilled water in the operation of this
proofer.
Operation Instructions
CAUTION
If water is spilled while filling the water
pan, thoroughly dry all surfaces including
the floor. Spilled water may cause serious
injury, loss of life, or damage to
equipment. Water may continue to drip.
To prevent the floor from becoming wet
and slippery, use a pan to collect dripping
water. Do not move the proofer when
water is in the reservoir.
Note: Use only distilled or purified water in
the Thermolizer to avoid build-up in the
water box of minerals and deposits normally
found in tap water.
1. Lift off water reservoir cover and fill water
reservoir (see Figure 3). If necessary, open
the lower door(s) and remove screen(s) or
tray(s) to access the water reservoir. Do not
fill beyond ½” of the top edge. When
finished, replace the cover and doors. If
equipped with the autofill unit, turn on the
water and the filler unit will stop at the
correct water level.
Note: Do not pull the control box out to gain
access to the water reservoir because water
may be spilled when moving the control box.
2. Turn on control box power switch.
3. Wait 25 minutes for the Thermolizer to
reach operating temperature.

control box.
b. Remove water reservoir cover.
c. Empty the water reservoir pan.

place and remove the control box from the
cabinet.
4. Remove and discard the plywood that the

closed, and tighten the screws. If more than
one door handle requires adjustment, start
with the one nearest the top of the proofer and
work down.
12. Turn the control box power switch to the off
position (see Operation Instructions)
13. Connect Thermolizer cord to power source
provided from the ThermoGlaze main power
box. Mail the attached warranty registration
form within ten days of installation.
