Operation

Operating in ‘Proof’ Mode
Ensure that power to the proofer / holding cabinet is
switched ‘On’ and the mains water supply is turned ‘On’.
It is recommended that the proofer / holding cabinet is
pre-heated empty before loading with product.
- Warm days, pre-heat for up to 10 minutes.
- Cool days, pre-heat for up to 30 minutes.
1. Set the Function Control (2) to ‘ON’.
The Power ‘On’ Indicator light (1) will illuminate when
the Function Control (2) is in the ‘ON’ position.
2. Set Thermostat Control (4) to desired proofing
temperature (20-40˚C / 65-105˚F).
The Heating ‘On’ Indicator light (3) will turn ’Off’ when
the cabinet has reached the set temperature.
3. Set Humidity Control (6) to the desired level.
As a general rule, set the humidity to between the 6 to
7 marks on the humidity control.
Increase or decrease the humidity control as required
for specific product types.
Humidity is required only to prevent the surface of the
product from dry skinning. Do not set the humidity to
high as the product will become sticky and wet on the
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 interior of the cabinet.
NOTE: Butter based product requires much less
humidity than breads
Operating in ‘Hold’ Mode
Ensure that power to the proofer / holding cabinet is
switched ‘On’.
1. Set the Function Control (2) to ‘HOLD’.
The ‘Power On’ Indicator light (1) will illuminate when
the Function Control (2) is in the ‘HOLD’ position.
2. Set the Thermostat Control (4) to the desired
Holding Temperature. (65-85˚C / 150-185˚F).
The Heating ‘On’ Indicator light (3) will turn ’Off’ when
the cabinet has reached the set temperature.
3. Humidity Control (6).
The humidity control function is not used in the ‘HOLD’
Mode. The setting on this dial will have no effect as the
wet element, water level sensor and water solenoid are
disabled.
4. Thermometer (7).
The thermometer will give an accurate reading of the
cabinet temperature to ensure that the product being
held is at the correct temperature.
Some parts of this proofer / holding cabinet
will become HOT during the Hold Mode and
could cause burns if touched accidentally.
Caution
Take care when opening the proofer /
holding cabinet door during the Proofing
Mode. Let hot air and steam escape before
removing or replacing food as the steam
produced can cause steam burns.
