Introduction
The 524-MCDC/-MCDCCE Pie Merchandiser is designed to
hold pies at proper serving temperatures. The cabinet has a
programmable temperature controller with a low temperature
alarm. The controller is factory pre-set for baked pies with a
holding temperature of 165°F (74°C). The controller’s
temperature setting needs to be adjusted for fried pies which
require a holding temperature of 155°F (69°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.
The cabinet is designed to hold 42 baked pies or 36 fried pies.
Each cabinet includes a removable pie caddy.

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 1°F or
more below the air temperature setpoint. It will turn off
when the cabinet temperature reaches the air
temperature setpoint. The controller display will flash
alternately LO and the actual cabinet air temperature
until it reaches the low temperature alarm setpoint.
