Proofer Assembly

PACKAGING

Before beginning assembly of the proofer, verify
that all the components necessary for the correct
configuration have been received. In addition to
the proofer other accessories may be required.

Single Sections:

The 25” (63.5 cm) legs and the optional regular
casters are packaged in the proofer cabinet.

Double Sections:

Thelowprofilecastersarepackagedinthelower
proofer section.

Accessories:

Proofer racks, rack guides and guide stops a re
packaged within the proofer cabinet.

CASTER ASSEMBLY

NOTE: Install the locking casters on the front of

theproofer. Install the non-locking casters
on the back of the proofer.

NOTE: If your proofer does not include casters,

proceed to the leg attachment section on
page 4.

Casters with 25” (63.5 cm) Legs

1. Insert the stem of a caster into the 1-1/2” I.D.
leg tubing. The caster shouldfit snugly. If not,
removethe castera ssembly and adjust as fol­lows:

Hold the large hex nut. Tighten the knurled
washerto expandtherubber sleevea nd allow
the caster assembly to fit snugly into the leg
tubing. Make sure the caster fits completely
inside the leg tubing.

2. Tightenthe largehexnutas muchas possible.
This will further expand the rubber sleeve

against the leg tubing wall. If the rubber
sleeves turn inside the leg tubing, removethe
caster and repeat the caster adjustment pro­cedure in 1.

Low Profile Casters

1. Carefully tip the proofer on it’s side.

2. Align the low profilecasters with the boltholes
in the corners on the bottom of the proofer.

3. Securethe casterstotheprooferwiththebolts

Maintenance

Cleaning and Preventative Maintenance

CLEANING THE PROOFER

Painted and stainless steel proofers may be kept
clean and in good condition with a light oil. Satu­rate a cloth, and wipe the proofer when it is cold.
Dry the unit with a clean cloth. On the stainless
front or interiors, heat tint and heavy discoloration
or deposits of baked on splatter may be removed
with a good non-toxic industrial stainless steel
cleaner. Apply cleaners when the proofer is cold,
and always rub with the grain of the metal.

WARNING!!
Disconnect the unit from power supply

before servicing or cleaning.

PERIODIC CLEANING
Daily:

Clean residue from the unit with a small brush.

Weekly:

Brush out control area.

Every 6 Months:

Clean the ductwork system and water pan.

CLEANING THE DUCTWORK SYSTEM

1. Disconnect the power supply to the proofer.

2. Movethe unittoallowaccesstotheremovable
rear panel. Lift the panel up and pull the bot­tom out. Carefully lower the panel while pull­ing the line cord through the access hole.

3. Slide the rear duct up to disengage the duct
flanges from the offset guide track. Remove
the duct. Set it on the left side of the unit.

NOTE: Be careful not to damage the control

wires or the capillary tube.

4. Slide the top duct straight out of the track
through the rear of the unit.

5. Remove the two quick-disconnect plugs.
Slideoutthelowerductassembly.DONOT
damage the blower wheel or heating ele­ments. The water pan assembly may be re­movedfromtheductforeasiercleaning.

6. Replace by reversing Steps 1---5 above. Be
sure to make proper electrical connections.

CLEANING THE WATER PAN

Visuallyinspectthew a ter panfor residualbuildup.
The water pan alone can be removed through the
front of the unit.

1. Disconnect the power supply to the proofer.

2. Removethet humbscrews fromthe lowercov­er. Grasp the cover by the sides. Pull out and
up toclear the three holding tabs mountedon
the inside bottom of the cover.

3. Remove the quick-disconnect plug from the
front of the water pan.

4. Pullup on the water pan todisengage thetab
from the front slot. Pull the pan forward.

NOTE: If the pan contains water , be careful

not to spill any inside of the unit.

5. Remove the pan from the proofer and clean
thoroughly .DO NOT immersethe pan inwa-

ter.

6. Replace by reversing Steps 1---5 above. Be
sure to line up the holes on the trim piece be­low the door with the lower cover. Lock the
tabs on the bottom inside of the cover.

OnBP-50unitsbe sure to insert the tab on the
right side of the lower cover into the slot in the
control panel cover.

7. Install the thumbscrews. Be sure to position

PREVENTATIVE MAINTENANCE

The best preventativemaintenance measuresare
theproper installationof the equipmentand a pro­gram for routinely cleaning the proofer.

Every 6 Months:

Thefanassembly blower motor,located inthelow­er air duct assembly at the rear of the unit, should
beoiledwithanSAE20weightoil.

1. Disconnect the power supply to the unit. Ap­plythe oiltothe twofillertubes locatedateach
end of the motor shaft.

The rest of the proofer needs no lubrication. If

maintenance or repairs are required, they
should be performed by qualified personnel
only.
