ASSEMBLY INSTRUCTIONS
OVEN AND PROOFER
WARNING! Risk of Electric Shock – Appliance must be secured to building structure.
DECK OVEN
Your Piper oven is shipped completely assembled with the exception of the chrome plated wire bake
racks. These bake racks are packed in a separate box with your shipment. The light weight, bake rack
should be placed on each deck with the four long wires down. The bake racks provide the correct spacing
between the deck and the product for proper baking along with making it easier to slide the pans in and
out of the oven.
PROOFER
Place the stainless steel water pan into the opening in the bottom of the unit, on top of the heating element.
There are mounting brackets on the top and bottom sides of the proofer for the side racks. Place the top
of the side rack in the top mounting brackets (front & back) and lift up. Then put the bottom of the side
rack in the bottom brackets (front & back) and push down to the vertical position. (see Figure #1 below).
Next slide the horizontal shelf racks in place so they rest on the rungs of the side racks. The side racks will
accommodate 9 shelf racks, 6 are furnished with the unit.
Figure 1
INSTALLING THE DRIP TROUGH
Mount the drip trough on the screws that are located on the front of the unit along the bottom of the proofer.

IMPORTANT!
YOUR LOCAL WATER CONDITIONS MAY PERMANENTLY DAMAGE THIS APPLIANCE.
FAILURE TO PROPERLY TREAT WATER MAY RESULT IN DAMAGE AND
WILL VOID YOUR WARRANTY. ENSURE THAT YOUR WATER SUPPLY MEETS
THESE MINIMUM WATER QUALITY SPECIFICATIONS BELOW BEFORE INSTALLING.
FAILURE TO MEET THESE REQUIREMENTS,
AND PROVIDE PROOF OF WATER QUALITY,
WILL VOID MANUFACTURERS WARRANTY.
PLUMBING INFORMATION
A 1/4” FPT (female pipe thread) connector is provided on all units that require a water hookup. Units with
automatic humidity and/or automatic steam injection have plumbing connections located on the right rear
corner post approximately 8” up from the floor.
WARNING! All units are required to have the water filter (provided by others) hooked up and
operational for warranty coverage.
NOTE: Piper’s automatic steam and humidity systems MUST be connected to a source of clean and
filtered water that meets or exceeds the requirements in the table below. The filter removes solid particles
and dissolves minerals (such as what is commonly found in hard water) to prevent scale build-up on the
water heating element.
Water system pressure should not exceed 120 PSI (8.78 KGCM2). Water consumption is less than 1 gpm
(3.78 liters/hour) and therefore the water supply pipe may be minimal.

OPERATING INSTRUCTIONS
DECK OVEN
• Turn the power switch “ON”. Interior lights will come on
• Turn all oven thermostats past 375°, then back to 375°. Indicator lights will come on and unit will begin
to pre-heat.
• Set timer for 1 hour and pre-heat until buzzer sounds. Oven has now reached proper temperature and
the unit is ready for product.
• When loading product, push pans completely to the rear of the oven.
• Set timer to appropriate number by turning the knob 5 minutes past the desired setting, then back.
CAUTION: This is a deck oven. DO NOT use an oven thermometer to check for temperature.
This is not the correct tool and will give an incorrect reading. (A pyrometer with a surface
probe is the correct tool.) Do not check temperature with product in the oven.
NOTE: If the bake on each deck is not uniform, adjust the thermostat by small increments (suggest
10-25 degrees) until all decks bake evenly. Once all decks are baking evenly, turn the oven off with the
power switch. This way you will retain the proper settings. Deck ovens operate on a radiant heat transfer
principle - settings and times should be monitored to achieve proper results.

OPERATING INSTRUCTIONS
PROOFER - MANUAL HUMIDITY
• Turn the power switch “ON”.
• Fill water pan with hot water (this step is not necessary if your proofer has the optional automatic
humidity.)
• Set thermostat to 100°. Allow approximately 15 minutes to reach temperature.
• Set the humidity control at #2 or #3 setting. At the proper setting your proofer door will have a light
haze on it. If water beads up and runs down the door, the setting is too high. You may need to adjust
according to atmospheric conditions.
Ideal proofing conditions consist of a temperature of 100°F and 60-80% humidity. Proofing times will vary
depending on the handling and the type of dough products. Sugar and yeast must be able to react
properly which takes a certain amount of time. This cannot be altered by adjusting the settings. Correct
proofing is very important for a successful bake.
Make sure your dough is completely thawed and at room temperature (if using frozen dough products)
before placing the products in the proofer! If not, it can take two to three times longer to proof.
HINT: You may want to place the dough (from the retarder) on a room temperature pan - not the cold
pan it was just sitting on. This helps shorten the proofing time. When putting cold pans in the proofer,
you bring the temperature down, taking longer for it to get back to the desired 100° temperature.
WARNING! Low water level or scale build-up in the water pan will cause premature failure of
the humidity system and will void the warranty. Add hot water as needed to keep water level in
pan above 1/2 full.
PROOFER - AUTOMATIC HUMIDITY
• Turn the power switch “ON”.
• Set thermostat to 100°. Allow approximately 15 minutes to reach temperature.
• Set the humidity control at #3 or #4 setting. At the proper setting your proofer door will have a light
haze on it. If water beads up and runs down the door, the setting is too high. You may need to adjust
according to atmospheric conditions.
• Drain humidity system DAILY. Drain valve is located on lower front corner post.
WARNING! By not draining the steam system daily, scale build-up in the steam generator may
cause premature failure of the system.

MAINTENANCE
To obtain the best performance from your equipment, it should be cleaned daily and maintained in good
condition.
SAFETY / ENVIRONMENTAL CAUTION
PERSONAL PROTECTION:
Check your company safety and environmental policy before cleaning or servicing.
Safety Tip! : Utilize protective gloves and safety glasses
ELECTRICAL POWER:
Before performing EXTENDED CLEANING where electrical components can become wet, the
power switch must be turned to OFF and the unit disconnected from the power source.
WARNING: Do not use any chlorinated or highly caustic cleaners, acids, ammonia or other
corrosive cleaners. These may cause corrosion and/or damage to the stainless steel. Piper
only approves soap and water for cleaning stainless steel. Water pan must be emptied and
cleaned after each serving period.
REQUIRED MONTHLY MAINTENANCE:
• Check thermostat settings
• Check operating temperature of unit
• Check electrical connection

GENERAL CLEANING
CAUTION: BURN HAZARD: Some exterior surfaces on unit will get hot. Use caution
when touching these areas.
DO NOT clean the unit while it contains any food product. Remove food product and
allow unit to cool completely before cleaning or servicing.
CAUTION: Prior to cleaning or maintenance, turn all switches “OFF” and disconnect the
power.
Stainless Steel and Aluminum:
• Piper only approves soap and water for cleaning stainless steel.
• NOTICE: Do NOT use chlorinated cleaners.
• NOTICE: Do NOT use acid based cleaners on the decks (such as Easy Off oven cleaner). This will
void the warranty and stain the metal permanently.
Hardened Foods or Scale Deposits:
• Clean hardened foods or scale deposits by utilizing a plastic scouring pad and a mild detergent.
Rinse completely with warm water and dry.
• NOTICE: Do NOT use steel wool
OVEN
The decks (oven shelves) should be swept clean of crumbs daily. When oven decks become dirty,
remove racks from oven and clean with a strong detergent and hot water. Spillage should be removed to
prevent burning and smoking in the unit.
PROOFER
To clean the proofer, wash the stainless steel interior with a mild detergent and hot water. We suggest
you leave the proofer door open every night to let it air dry. If your model has the manual fill water pan,
we suggest soaking it with a strong vinegar solution overnight to remove the mineral build up.
WARNING! Low water level or scale build up in water pan will
cause premature failure of the humidity system and voids the warranty. Add hot water as
needed to keep water level in pan above 1/2 full.
DOORS
Wipe the doors and glass off with a mild detergent and hot water daily. For glass Piper recommends
Wright’s Silver Cream which can be purchased from local stores.
EXTERIOR SURFACES
To maintain a shiny exterior, lightly wipe the stainless steel surface with lemon oil or stainless steel
cleaner.
