PIE MERCHANDISER
CARTER-HOFFMANN MODELS MDPM2 & MDPM4 MDPM2

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 165 o F (74 o C) for baked pies or 155 o F (69 o C) for fried pies, and a low temperature alarm of 140 o F (60 o C). 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.
