Optional Motor Davit
This accessory is available to aid in the removal of fan motors and gear boxes. The assembly consists of a davit and a mounting
base/channel that is attached to the side of the unit next to the access door (Figure 18). Both of these items will ship loose in the
unit’s basin.
Use the following procedure to install the mounting channel:
1. Place the mounting channel on the factory-installed
mounting brackets near the access door.
2. At each hole, attach the mounting channel to the bracket
using 3/8” (10mm) hardware as shown in Figure 19.
Optional Heater Package
This accessory is available to prevent the basin water from
freezing during winter operation. The heater package consists
of a heater, a low water cutout switch and a thermostat. The
heater is installed at the factory. The low water cutout switch is
shipped loose in the rigging box and will need to be screwed
into the screw tight fitting installed in the unit. The thermostat is
attached to the side of the unit at the factory. The bulbwell for
the thermostat is shipped loose in the rigging box and will also
need to be screwed into the screw tight fitting installed in the
unit. See Figure 20 for heater package location diagrams.
