Preface

The EP18/24 & EP18/24/34 Econo Proofers are
designed for retail bakery, in-store bakery and
the donut shop. It features six individual 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
eighteen seconds.

The EP18/24/34 Econo Proofer has a warning
light that glows when humidity water is low in
the reservoir. In the European Community, the
machines are available with the following
electrical configurations:

• 220/240 volts, 1 phase, 50/60 hertz

A thorough understanding of how to operate,
clean, and maintain the Econo Proofer 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.

Do not permit water pan to run out of water.
Check often. Use only soft or distilled water in
the operation of this proofer.

• Distilled or filtered water must be used

in the proofer to avoid corrosion.

1 Operation

Control Functions

SEE FIGURE 2, Following:

A. HUMIDITY CONTROL PILOT

LIGHT: Indicates when the water

heater element is heating.

B. HUMIDITY CONTROL: Control for

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.

C. WARNING – LOW WATER PILOT

LIGHT: Indicates whenever the water
in the water reservoir is getting low. At
the same time this pilot light comes on, a
buzzer will go off, and power to the
water heating element is automatically
turned off. NOTE: This will result in a
drop of loss of humidity in the proof box.

D. HEAT CONTROL: Control for the air

heating element.

E. HEAT CONTROL PILOT LIGHT:

Indicates when the air heat element is
heating.

F. CONTROL BOX POWER SWITCH:

Controls the power to the control box.

G. CONTROL BOX POWER PILOT

LIGHT: Indicates the power in the
control box is on.

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
Proofer 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
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 cover and doors.

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. Set heat control to desired temperature.

4. After proof box is up to temperature, turn

humidity control to high. When desired
humidity has been achieved, turn humidity
control down to a midpoint setting. NOTE:
final optimum settings of both heat control
and humidity control can only be determined
through daily use of the proof box.

3 Cleaning

Proof Box

Once a week, clean the proof box as follows:

1. Remove and clean Plexiglas doors with
warm water.

2. Disconnect from power and remove control
box from cabinet.

3. Remove and clean the screen rack angles,
angle supports, and air duct.

4. Wipe the cabinet interior clean.

5. Special attention should be given to cleaning
the water box (Item 2 of Control Box Assy,
parts list drawings). Clean the water box as
follows:

A. Remove water reservoir cover.
B. Empty the water reservoir pan.

Following are some cleaning charts, to help keep track of regularly scheduled cleaning.

C. Remove water box access cover thumb

screw and rotate access cover to open
position. (see Figure 3)

D. Use a rubber syringe baster to remove

sediment from the water box. Wipe the
inside of the water box with a rag.

E. Add a small amount of water to the

water reservoir pan. Water should flow
freely into the water box. If not, clean
out the water line between the water box
and the water reservoir pan. Check for
blockage at the water box inlet hole first.

F. Close water box access cover and fasten

with thumbscrew.

G. Replace water reservoir cover.

1 Installation

Unpacking and Assembling
the Econo Proofer

Use a forklift to transport the shipping crate to
the workstation.

• Break down the shipping crate.

• Remove the packing materials from the

proofer, including foam, tape, brown paper,
plastic, and white protective coating.

Do not remove the plastic from the
Plexiglas doors at this time.

• Cut the bands holding the control box in

place and remove control box from cabinet.

• Remove and discard the plywood that the

control box was resting on.

• Inspect the machine to see that no parts are

bent, scratched, or otherwise damaged. If any
damage has occurred in shipping, file a
freight claim with the shipping company
immediately.

• Clean the humidifier water box and the fill

box. Refer to Section 3 for cleaning
instructions.

• Install screen rack angles onto angle supports

by tilting the angles up and sliding the flange
into the notches of the supports. See Figure 1.

WARNING

If water is spilled while cleaning the

proofer, be sure to dry the floor

thoroughly.

• If not already done, remove the packing

material from the control box and put water
reservoir cover in place over water reservoir.

• Place control box into cabinet, push cord

through the hole in the floor, to the left of the
control panel, and close cord opening cover
plate.

• Remove protective covering from the

Plexiglas doors. Clean the doors with warm
water.

• Insert the hinge pin on right side of door into

• Note: due to vibration in shipping, the

door handles might get out of adjustment.
To adjust door handles: loosen the screws
which fasten the handle to the plexiglas
door, adjust position of the handle so it
just clears the bottom of the door above
when both are closed; tighten screws. If
more than one door handle requires
adjustment, start with the one nearest the
top of the proofer and work down.

• Turn humidity control, heat control, and

control box power switch to their off
positions (see Operation Instructions)

• Connect Econo Proofer cord to power source.

Check wiring diagram and data plate for
proper power specifications.

• Mail the attached warranty registration form

within ten days of installation.

• Keep this manual for future reference. Put it
where you know you can find it.

Initial Cleaning

Remove all the packing materials. Wipe the
Econo Proofer with a soft, damp cloth. Dry these
areas completely.

WARNING

To avoid electrocution or other injury, turn

off the machine’s main power before

attempting any cleaning, disassembly,

adjustment, or repair.
