Installation

Toaster Grills

Models 247 & 248

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 1-800-722-7853 or 630-462-8800 to arrange for a replacement unit.

Before first use, clean and condition the platens (see Conditioning Platens).

Setting the Controls

The model 247 & 248 Toaster Grills provide two modes of operation: DEDICATED MODE and PRODUCT MODE.

• DEDICATED MODE is a simple mode of operation for toasting buns that is similar to the 213, 411 & 416 Series T oaster Grills, with a set toast time and temperature for one product “BUN1”.

• PRODUCT MODE allows you to set both the t oasting time and temperature individually for four additional products. Note that it may take several minutes for the platen to heat up or cool down to a new temperature setting. You can also change the display to any four character name of your choice for each of the products to indicate which product is being toasted.

• Furthermore, 247 and 248 T oaster Grills allow you to manually initiate the power-saving mode. (See Figure 1.)

NOTE: When using this unit, the ambient temperature at the mounting site should not exceed 43°C (110°F).

CAUTION

All electrical connections must be in accordance with local electrical codes and any other applicable codes.

Plug the unit into an applicable electrical receptacle.

Conditioning the Platens

Toaster Grills

Models 247 & 248

To minimize bun-sticking, the platens should be wiped

weekly with McD Bun Toaster Grill Release Agent.

CAUTION

Use only McD Bun Toaster Grill Release Agent on bun Toaster Grills. Other products may cause damage and void the Warranty.

A. Dust all loose crumbs from Toaster Grill surfaces. B. Apply McD Bun T oaster Grill Release Agent to cool or

warm Toaster Grill platens.

To coat the platen surface, thoroughly wet a clean, folded

customer napkin or paper towel with Toaster Grill Release Agent, and place it on No. 257 cleaning tool.

A. Rub a generous amount of the Release Agent over the

entire surface of the platen until well coated.

B. Repeat Steps 2 & 3 for other platens, including

undersides.

WARNING

BURN HAZARD! Use protective gloves and No. 257 cleaning tool when con ditioning hot platens.

IMPORTANT! Do NOT wipe Toaster Grill with a damp cloth

after Release Agent is applied. Doing so removes Agent and causes sticking.

Toaster Grill platens must be clean and dry.

Reapply Release Agent weekly to all platen surfaces

while Toaster Grill is cold. If sticking occurs between weekly applications, reapply

Release Agent more frequently as described in Steps 1 – 3.

Page 14

45 minutes and the temperature has stabilized. Do NOT use the toaster during this period!

IMPORTANT! If the temperature reading on the Platen is greater than ±3°C (±5°F)

compared to the toaster temperature display, proceed with the following. If temperature reading is within range, toaster is functioning properly and does not need calibration.
