temperature, until temperature reaches the setpoint.

Once the cabinet reaches setpoint, the digital readout will display “P1”. This
indicates the cabinet is at temperature and ready to hold product. Load product
into the pans and insert into cabinet cavity.

The cabinet has six programmable timers (“P1”, “P2”, “P3”, “P4”, “P5” and “P6”)
for each cavity. Different program times can be used for different parts of the day
