Temperature Control Adjustments
An air curtain type of merchandiser is affected by the
temperature and relative humidity of the surrounding
ambient.
A. The adjustment knob and body of the temperature
control is mounted to the left interior back panel of
the cabinet, about six inches off of the "floor" of the
cabinet, in a recessed area, near the evaporator coil.
- To raise the product temperature (warm up the
cabinet), turn the control knob counterclockwise.
- To lower the product temperature (cool down the
cabinet), turn the control knob clockwise.
B. If the above does not give desirable results, further
adjustment is possible in the field. Disconnect power
to the cabinet. Remove the full length back panel
that the temperature control is mounted to: (See
figure 1 & 2).
The temperature probe is inserted in the left end
of the evaporator coil.
- To raise the product temperature (warm up the
cabinet), relocate the temp. control probe in the top
tube well location in the end of the coil.
- To lower the product temperature (cool down the
cabinet), relocate the temp. control probe in the
bottom tube well location in the end of the coil.
NOTE
The sensor end of the temp. control should be inserted in
the tube well until it stops (bottom out). Reassemble the
lower back panel, restart the unit and set the control to
midpoint "5", for further temperature adjustment.
