DESCRIPTION

Heater and defroster kits in the HD35/HD3515 Series are designed for enclosures in the EH3500
Series and EH3515L Legacy® Series. The HD35 Heater and Defroster Kit is designed for enclosures
only in the EH3508 Series and EH3512 Series. The HD3515 Heater and Defroster Kit is designed
for enclosures only in the EH3515 Series and EH3515L Legacy® Series.

These kits contain a thermostatically controlled heater and a continuous-duty defroster. The heater
turns on when the temperature drops to 50°F (10°C) and turns off when the temperature reaches
80°F (27°C).

The heater and defroster are attached to a bracket that replaces the window brackets currently
used to hold the viewing window in place. Because of this bracket, the viewing window size is
reduced to a two-inch (5.08 cm) diameter circle.

The HD3515 Heater and Defroster Kit contains two heaters. You install one heater in the front of
the enclosure and the other heater in the rear of the enclosure. The rear heater is attached to a
rear heater bracket, and the rear heater bracket attaches to the rear of the enclosure. If you are
also installing a blower kit, you install the rear heater bracket between the blower and rear of the
enclosure.
