DESCRIPTION/SPECIFICATIONS
Description
The Proofer is a stainless steel, electric, forced air, proofer with adjustable temperature
and humidity capabilities. This proofer offers consistent proofing at all rack levels due to
the careful positioning of the heating and humidification systems.
In addition to the above, this proofer also offers many other features. It is compact,
attractive, quiet, and is easily maintained. Should electrical servicing ever be required the
electrical components are readily accessible by removing the side panel.
The clear polycarbonate door with its high temperature seal allows a full view of the trays
in the proofer during proofing.
The proofer also has one of the fastest temperature and humidity recoveries on the
market allowing the proofer to be turned off during non-peak hours, thus saving energy.
The proofer controls allow easy adjustment of temperature and humidity. This allows
proofing by even inexperienced individuals.

INSTALLATION / SETUP
Inspection
Before accepting delivery inspect the carton and machine for damage. Note any damage
found on the shipping documents. Remember shipping damage is not covered by your
warranty, and is the responsibility of the carrier. Also report the damage to the dealer
from which the proofer was purchased for further direction and assistant in filing a claim
with the carrier.
Location Selection
Select a location where the proofer will be used. The proofer must be set on a flat level
surface. It should have a grounded power supply of the same rating as shown on the
nameplate located on the rear of the proofer and this power supply must be capable of
carrying the load that the proofer will put on it (See “Electrical Connection” page 3-2). The
proofer must also be placed near a water supply. (See “Water Connection” below).
Proofers with casters should be placed so that they have a minimum of two inches on
each side and a minimum of four inches in the rear of the proofer to provide for proper
water, and electrical connections.
Proofer Setup
Proofers may stand alone or be stacked with a Oliver oven ( oven must be on top of
proofer ). For associated mounting heights for the above options see figure 3.0 on page
2-2.
CAUTION
USE CARE WHENEVER MOVING OVENS MOUNTED ON PROOFERS AS THEY ARE
TOP HEAVY AND PRESENT A TIPPING HAZARD.
A stacked oven should be setup as shown on page 2-2 being sure that the alignment pins
on the top of the lower proofer are securely positioned into the holes in the base of the
upper oven.

Electrical Connection
WARNING
THE PROOFER MUST BE CONNECTED TO A PROPERLY GROUNDED ELECTRICAL
SOURCE OF THE SAME RATING AS THE MACHINE. FAILURE COULD RESULT IN
AN ELECTRICAL SHOCK WHICH MAY CAUSE INJURY OR DEATH.
WARNING
ALL WIRING AND ELECTRICAL REPAIRS SHOULD BE DONE BY A QUALIFIED
ELECTRICIAN. FAILURE TO DO SO MAY CAUSE SERIOUS INJURY OR DEATH.
CAUTION
A SPECIAL HEAVY DUTY ELECTRICAL SERVICE MUST BE PROVIDED FOR SAFE
OPERATION OF THE PROOFER.
The following service requirements are recommended, dependent on the voltage of the
unit you have purchased. Your proofer’s requirements can be found on the nameplate
attached to its rear surface.
For voltages other than those shown below please contact the factory.
1 phase, 60 hz, 115VAC, 14.5 Amps.
( 20 amp Dedicated Circuit )
The proofer is shipped from the factory with a power cord. Leave at least two feet of slack
so that access can be gained to the proofers right side. This makes sliding the proofer out
for service more convenient. Whatever method is used the proofer should be wired in a
manner which would conform to the U.S. “National Electric Code”.

695 PROOFER
0695S20004 3-3
Water Connection
All water connections must comply with the basic plumbing code of the Building Officials
and Code Service Sanitation Manual of the Food and Drug Administration (FDA)
CAUTION
WATER PRESSURES GREATER THEN RECOMMENDED CAN CAUSE EXCESS
WATER TO ENTER THE PROOFER CAUSING WATER TO LEAK AT THE DOOR AND
ALSO CAUSE THE HUMIDITY TO DROP SEVERELY AFFECTING THE PROOF. USE
A PRESSURE REGULATOR TO REGULATE THE PRESSURE.
The proofer must be connected to a water supply to enable the proofer to produce
humidity for baking. As shipped from the factory the proofer will have a water connection
point at the back of the proofer, (See figure 3.0 page 2-2). This connection has an internal
1/4” NPT thread. Water pressure should be a maximum of 60 to 70 PSI and the water
must clean. Use a pressure regulator and a water strainer/filter to meet these guidelines.
Before making the water connection flush all lines and install the regulator and filter.
Remember solenoid failure and related problems caused by dirt may not be covered by
your warranty.
NOTE
HARD WATER LEAVES MINERAL DEPOSITS ON GLASS AND OTHER SURFACES
WHICH DETRACT FROM PROOFERS APPEARANCE.
Test Cycle
After completing the Set Up, Electrical and Water connections, you may wish to run the
proofer through a test cycle to verify that everything is ready. Use the following sequence
to run the proofer through a test cycle.
•Turn the power switch on – internal fan should run.
•Set temperature control to highest setting – proofer should begin to heat. (allow
several minutes).
•Set temperature control to off, humidity control to highest setting – water tray
should begin to fill and shut-off when proper level has been reached. water should
also begin to heat. (allow several minutes).

Beginning Operation (continued)
Indicator LED’s show when heat and / or steam are on.
Up and Down Keys
The Up and Down keys are used to adjust settings (either Time, Temperature, or RH).
Settings (as opposed to actual readings) are recognized on the display by 2 things:
the left most triangle is lit (i.e. means that 80º C is the set point, and not the
actual temperature); the Up/Down keys LED’s are also lit, meaning that they are usable to
modify the displayed data.
To modify a setting, first press the required button for 2 seconds (Temperature or RH) and
then use the Up or Down keys to modify it. To modify proofing Time, simply press Up or
Down key directly when countdown time is displayed (while Proofing) or if Standby or Auto
states are active.
After changing settings, there are up to 3 ways to accept the new values:
•Re-press the Temperature or RH key (if changing one of those settings)
•Press the Start key “I”
•Wait for 5 seconds
In any case, if a proofing cycle was already active when the setting was changed, it will
simply continue with the new values. If the changed setting was Time, the new time is
used (i.e. the Proofing cycle is restarted using the new Time).
When accepting a change, the Up/Down LED’s shut off (as well as the Temperature or
RH LED’s and the settings triangle), and the display reverts to the previous state display
(Proofing if Start was pressed).
Temp Key
A normal press of this key forces the display to show the current Temperature reading.
If the Temp key is held for 2 seconds, the display will show the current Temperature
setting. Temp key, as well as Up and Down LED’s are also lit, indicating that Temp setting
can be changed if needed.
In either case, the display reverts back to its previous mode after 5 seconds of no activity.
(continued)

695 PROOFER
0695S20005 4-5
Beginning Operation (continued)
RH Key
A normal press of this key forces the display to show the current RH reading.
If the RH key is held for 2 seconds, the display will show the current RH setting. RH key,
as well as Up and Down LED’s are also lit, indicating that RH setting can be changed if
needed.
In either case, the display reverts back to its previous mode after 5 seconds of no activity.
Start and Stop keys
These keys control the various states of the unit. Pressing Start “I” normally starts a
Proofing cycle with the currently memorized settings (Time, Temperature, and RH).
Pressing the Stop key “O” cancels the current Proofing cycle if one is active. The unit
returns to Off/Standby mode.
Time
Timer information is the default view in most states. The unit displays the time left if
Proofing, or the current set time if in Off/Standby state.
Time is displayed in the standard HH:MM format. During the Proofing cycle, the time is
also displayed as HH:MM; however, in the last 10 minutes of a Proofing cycle, MM:SS are
displayed. Maximum time programmable is 11 hours and 59 minutes.
If time is set to 0:00, then it is assumed the user does not wish to use the timing functions,
and the display will default to displaying current temperature when proofing. Standby in
this case shows the current temperature too. Start button is not lit in this case either.
All other functions work normally.
