sloped toward the cabinet drain pan for an
Duct securement to the collar may be completed using the predrilled flange. The seam should be made air and watertight by caulking or gasketing.
When a blower is installed downstream from the Trion cabinet, the ducting between the cabinet and the blower will be under negative pressure and should be made air tight to prevent infiltration of contaminated air.
After the ductwork has been installed, clear remaining material or debris from inside ducts and bottom of cabinet, and then
NOTE: Follow the directional arrows located on the cell end plates. The side of each cell containing the spiked ionizer blades must be located on the air entering side of the cabinet. The brass contact plungers on the cell should be inserted toward the back of cabinet. Also, mist suppressors when specified must be located on the air entering side of the cabinet.
4. Connect Drain
Connect a drain line to the pipe coupling provided in the cabinet drain basin in accordance with the governing plumbing codes. The drain line must be sealed with a trap or other means to prevent air by pass. If a trap is used, it should hold sufficient water column to overcome the system air pressure and to assure that loss of liquid from evaporation between cleaning periods will not break the seal. The drain line should not be smaller than the drainpipe coupling.
5. Mount Controller
The Controller should be mounted at eye level and located as close to the air cleaner as practical. It must be mounted indoors out of the weather unless supplied with a weatherproof cabinet. Allow sufficient space in front of the access door(s) for service. Refer to appropriate Control/Remote PWM Box Outline Drawing for mounting hole layout and dimensions.
6.Complete Wiring
(a). High Voltage Wiring
WARNING:
EXERCISE ALL THE NORMAL PRECAUTIONS WHEN WORKING WITH HIGH VOLTAGE AND COMPLY WITH NEC AND ALL APPROPRIATE LOCAL CODES.
The high voltage wiring entails interconnecting the power supply(s) to the
Refer to the Field Wiring Diagram. Two high voltage leads, Red/Black Tracer for the ionizer and
one Red for the collector, are factory furnished. Each lead is to be run in separate conduit and must be of continuous run (do not splice) between the controller and the
(b). Primary Wiring
The Controller is the main distribution point for all primary wiring. The various electrical components involved are connected to and powered from the controller. These interlocks are safety switches that prevent access to the charged high voltage components without first turning “OFF” the high voltage by interrupting the 24 VDC input to the PLC. Refer to the appropriate Field Wiring Diagram.
(c). Grounding
An earth ground must be provided to the Model 75 cabinet and control. All ground connections must be in contact with bare metal and securely affixed. Ground conductor size and connection means will be in accordance with all applicable electrical code standards.
7. Check Out for System Start-up
When the installation has been completed, assure that the equipment is ready for
A.All construction debris is removed from the ionizing- collecting cells, drain basin and ductwork.
B.The drain line from the Trion drain basin is clear and completely connected to its point of termination.
C.Supply line power is available and electrical wiring is completed to the following components:
1.Controller
2.Electrical Interlocks
