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.
