INTRODUCTION

The MDPM2 & MDPM4 Pie Merchandisers are designed to hold pies at serving temperature. The cabinets have a programmable controller with a low temperature alarm. The controller is factory pre-set for a holding temperature of 165oF (74oC) for baked pies or 155oF (69oC) for fried pies, and a low temperature alarm of 140oF (60oC). The heater can be accessed for service by removing the top cover. There is also a bottom panel to access the wiring and the switch. Each cabinet includes a removable pie caddy that holds individually boxed and stacked pies.

SAFETY

Knowledge of proper installation, operation and maintenance procedures is essential to ensure safe operation of any equipment.

Turn the power switch on. Preheat cabinet for 30 minutes. When the cabinet is turned on, the air heater will operate until the cabinet reaches the air temperature setpoint. The display will read the actual cabinet temperature. The heat “ON” light will illuminate when the cabinet air temperature is below the air temperature setpoint. The controller display will flash alternately LO and the actual cabinet air temperature until it reaches the low temperature alarm temperature setpoint.

NOTE: The pie caddy has a reserve storage of 12 or 18 pies. This reserve is intended to provide additional pies while a new batch of pies are being baked. Holes beneath the door provide visual indication of low pie level in the cabinet.

The controller has been factory pre-set for a holding temperature of 165oF (74oC) for baked pies, 155oF (69oC) for fried pies, and a low temperature alarm of 140oF (60oC). In most cases, the temperature will not need to be changed. However, if changes are necessary, the controller is programmable.
