We are confident that you will be delighted with your E85 PROVER, and it will become a most valued
appliance in your commercial kitchen.
A new oven can seem very complex and confusing at first glance. To ensure you receive the utmost
benefit from your new Prover, there are two important things you can do.
Firstly
Please read the instruction book carefully and follow the directions given. The time taken will be well
spent.
Secondly
If you are unsure of any aspect of the installation, instructions or performance of your prover, contact your
E85 dealer promptly. In many cases a phone call could answer your question.
Introduction

clearances are to be adhered to:
Electrical Connection
• E85 provers are supplied with pre-fitted cords. Ensure unit is fitted with appropriate cord and plug.
• To access the electrical connection terminal block, grounding lug and strain relief, remove the
right hand side panel.
WARNING - THIS APPLIANCE MUST BE EARTHED / GROUNDED
Water Connection (Auto Fill Models Only)
• A cold water supply should be fitted to the water inlet (¾” BSP connection) which is located near
the rear of the right hand side of the unit.
• Alternately, a connection elbow and sealing washer is supplied with this unit for direct connection
of a ½” ID hose, and is recommended for easy installation and service.
• Connect water supply - Max inlet pressure 80psi / 550kPa.
• Turn on water supply to check for leaks.
Rack Width

Operation
Power
Turn to switch power on or off (on horizontal, off
vertical). Indicator illuminates when power is on.
Thermostat
Temperature range 25-40°C (75 - 105°F).
Indicator illuminates when the elements are cycling
ON to maintain set temperature.
(Controls the prover air temperature)
Humidity Control
LO - Humidity setting for butter based pastries
(croissants, Danish pastries etc.)
MED/HI - Humidity setting for yeast based breads
and doughs.
Indicator illuminates when elements are cycling ON
to maintain set temperature.
(Controls the prover humidity)
Condensation channel
There is a condensation channel below the prover door
for the purpose of collecting door condensation run-off.
A diameter 12.7mm (½”) drain outlet is provided in the
centre of this channel and is factory fitted with a drain
bung. The drain facility can be used in three ways:
• Remove the bung when emptying is required and
drain into collection vessel. Refit bung until
drainage is next required.
• Place a suitable collection vessel or pan on the
floor below the drain outlet and remove bung
permanently for continual draining. Empty
collection vessel or pan as required.
• Remove the bung and connect a 12.7mm (½”) I.D.
hose or similar to drain outlet and route hose to
permanent drainage.

Operation

Operating the Prover
Ensure that power is supplied to the unit and the water trough is filled
It is recommended that the prover operates empty before loading with product
- Warm days up to 10 minutes
- Cool days up to 30 minutes
1. Ensure water tank is filled with water
Standard models: Open the prover door and fill the water tank located at the front of the right
hand side rack. The tank should be filled to 20mm (¾”) from the top of the tank. Remember
to top up the water tank when the water level is below the halfway level in the tank (before
the heating element is exposed).
Auto fill models: Check that the water tank is full and that the heating element is well
covered.
2. Turn power on
The indicator light will illuminate whenever the switch is in the “I” (on) position.
3. Set thermostat to desired proving temperature
The indicator light will illuminate whenever the elements are cycling on to maintain the set
temperature.
25-30°C Butter based pastries
35-40°C Yeast based breads and doughs
4. Set humidity to desired level
The indicator light will illuminate whenever the elements are cycling on to maintain the set
humidity.
As a guide;
Set humidity to between ‘LO’ and MED’ marks on control panel as a general rule.
Increase or decrease as found necessary for specific product types.
Humidity is required only to avoid product dry skinning on surface. Do not set humidity
such that product becomes sticky and wet on surface. A silky to touch surface on the
product is a general recommendation for correct humidity levels.
Avoid excess humidity levels as this will also create excess condensation in the cabinet
interior.
Note: Butter based product require much less humidity than breads.

11
Operation
Bake-Off
This prover has been designed for use together with a refrigerator and oven to take frozen uncooked
yeast or butter based products to finished cooked products.
1. Prepare product
Arrange frozen products onto baking trays.
2. Thaw
Refrigerate at 4°C (40°F) overnight. Do not leave standing at room temperature or the product may
dry out.
3. Prove
Place thawed products directly from the refrigerator into the pre-heated prover. Prove for 30-60
minutes dependant on product and food proving recommendations.
4. Bake
Place proved product directly from the prover into the pre-heated oven. We recommend the E35
Turbofan Oven.

Operation
Problem Solving
Product collapses
When using frozen dough which collapses or shrinks in the oven after proving, this is caused by too
much proving. Reduce the proving time for the next batch.
Dry product
The dough piece in the prover should never be dry to the touch. A moist, firm and silky membrane
should cover the dough piece during proving.
Wet product
The dough piece in the prover should not be wet to touch whilst proving and should not adhere to
fingers. Water should not condense on the trays. If it does there is either too much moisture or too
little heat in the prover.
If there are any problems with your dough the most likely causes are as follows:
• Too much heat and too little moisture.
• Not enough heat and too much moisture.
• Proving time too long or too short.
• Incorrect oven temperature.
• Incorrect maturity adjustment in the formulation of the dough for the flour.
• Incorrect thawing procedure, or handling of the dough after thawing.
Hints
Heat
It is better to operate the prover at a lower temperature with adequate moisture rather than at a
hotter temperature with too little moisture.
Yeast
Yeast activity starts very slowly at about 5°C (41°F) and increase in speed or gas production as the
temperature rises. When a temperature of approximately 60°C (140°F) is reached, the yeast is
killed and baking of the aerated product starts. Thus different rates of proving occur as the
temperature changes.
Flour
The amount of proving required is determined by the quality of the GLUTEN in the flour. Gluten is
a rubber like product and can perish if stretched too far by too much proving. Collapsing of the
product or shrinkage will occur.
Proof
You must recognise the proof of the product by the appearance of the dough rather than the size.

Cleaning
13
Cabinet
Clean with a good quality stainless steel cleaning compound. Harsh abrasive cleaners may damage
the surface.
Side racks
To remove, take hold of the centre rung and lift upwards to disengage the rack key-holes from the
hanger studs. To replace, hold horizontally, engage keyholes onto studs and push down.
Door
Wash with warm water and detergent solution using a soft sponge in straight lines up and down the
door. Rinse with clean, warm water and dry off.
Water tank
Remove the RH side rack and remove tank by lifting off its hanger studs. Clean with warm soapy
water. Rinse thoroughly and refit.
Water tank element
When the element becomes limed/scaled remove the water trough and clean. Replace water trough
and half fill with white vinegar or acetic acid, then fill to the normal level with water. Switch the unit on,
turn the humidity to HI and operate for approximately 30 minutes. Remove trough and clean the
element with a damp cloth when cooled. Rinse out the through and refit to unit.
This procedure is recommended to be carried out once a week. Frequency of cleaning the element
may be increased or decreased depending on the lime depositing on the element.
Caution:
ALWAYS TURN OFF THE POWER SUPPLY BEFORE CLEANING.
THIS UNIT IS NOT WATER PROOF.
DO NOT USE WATER JET SPRAY TO CLEAN INTERIOR OR EXTERIOR OF THIS UNIT.
