Condensation channel
There is a condensation channel below the proofer 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 next drainage.
• 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 in PROOF Mode
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 the water tank is full and that the heating element is well covered.
2. Set function to PROOF
Indicator light will illuminate when the switch is in the “PROOF” position.
3. Set thermostat to desired proving temperature
Indicator light will illuminate when the elements are cycling on to maintain set temperature.
25-30°C Butter based pastries
35-40°C Yeast based breads and doughs
4. Set humidity to desired level
Indicator light will illuminate whenever elements are cycling on to maintain 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.
Butter based product require much less humidity than breads.
Bake-Off
Note:
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 overnight. Do not leave standing at room temperature or 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
Moffat 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 and increase in speed or gas production as the
temperature rises. When a temperature of approximately 60°C 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.

Operation
Operating in HOLD Mode
Ensure that power is supplied to the unit and the water trough is filled
It is recommended that the cabinet operates empty before loading with product
- Warm days up to 10 minutes - Cool days up to 30 minutes
1. Set function to HOLD
Indicator light will illuminate when the switch is in the “HOLD” position.
2. Set thermostat to desired holding temperature
Indicator light will illuminate when the elements are cycling on to maintain set temperature.
3. Humidity
The humidity is not used in HOLD mode. The setting on this dial will have no effect as the
wet element is disabled.
4. Thermometer
The thermometer gives an accurate reading of the cabinet temperature to ensure that the
product being held is at the correct temperature.
