2.0 COMPONENT DESCRIPTION
2.1 CABINET
2.2 FANS
2.3 CONTROLLER
The cabinet is built of 22 gauge (0.64 mm) galvanized steel and is painted white. It has a
hinged, removable door. The exterior of the unit boasts four air pressure test ports, one low-
voltage terminal strip, an access/viewing port, and locations for four duct connectors, (6" or 8",
shipped loose).
2.1.1 Removable Door with Interlock Switch
The insulated access door is hinged on one side and has two securing latches on the other side.
The hinges are separable to allow for removal of the access door for servicing. The door has an
access/viewing port built in to permit adjustment of the fan potentiometers. Directly behind the
access door is a pressure-sensitive interlock switch that will shut off power to the unit if the
door is opened during operation. Also installed on the door are four air pressure test ports, used
for connecting a manometer and taking air pressure measurements.
The EV Premium has two advanced, high efficiency electronically commutated (EC) 120 VDC
variable speed fans. One fan is used for intake air (Outdoor Air/Supply Air) and the other fan
is for the exhaust airstream (Return Air/Exhaust Air). The speed of each fan is controlled
independently by a 0–10 VDC signal from the controller.
The controller provides the signal to the EC motors using integral potentiometers. Incoming line
voltage powers both fans and also a step-down Class II transformer which provides 24 VAC to
the externally-mounted low-voltage terminal strips. The controller has four potentiometers that
are adjusted by the user to establish fan speeds for each operation mode.
