Installation
A. Remove the unit from the carton and inspect for signs of damage.
If there is damage to the unit:
• notify the carrier within 24 hours of delivery
• save carton and packaging materials for inspection purposes
• contact your local dealer, or if purchased directly, the Prince Castle
Sales Department at 800-722-7853 or 1-630-462-8800 to arrange
for a replacement unit.
NOTE: When installing this unit, the ambient temperature at the
mounting site should not exceed 100°F (37.8°C).
B. Place the bin on a counter and seal the base to the counter with
food-approved sealant.
C. Plug the power cord into the bin and connect the plug into the
proper electrical outlet. All connections must be in accordance with
local electrical codes and any other applicable codes.
NOTE: The electrical receptacle should be a dedicated outlet. No
other equipment should be operating on the line (refrigerators, fryers,
etc.).
D. Turn the power switch to ON. Allow 30 minutes for warm-up.
NOTE: If the unit is to network with other Prince Castle units, a Retro
Bun Timer may be connected to any one bin in the chain. Contact
Prince Castle for more information.
Initial Startup
NOTE: During the first few hours of operation, you may notice a faint
odor. This is normal, and the odor disappears after the first few hours
of use.
The bin is tested and calibrated at the factory before shipment.
However, due to temperature and climate changes during shipment,
the insulation in bin can absorb moisture. The odor during the first few
hours of use is from the drying out of the insulation (moisture is driven
from the insulation’s binders, a starch-like material).
Resetting to Factory Defaults
7
To revert all settings back to the original factory defaults (product
times on button bars):
1. Turn the unit off.
2. Press and hold both UP and DOWN arrows.
3. Turn the unit back on and wait 5 seconds.
4. Release UP and DOWN arrows.
NOTE: All previously saved settings are lost upon resetting the
defaults! Use with caution.
Prince Castle reserves the right to change specifications and product design without notice. Such revisions do not entitle the buyer to
corresponding changes, improvements, additions or replacements for previously purchased equipment.
