2.0 INSTALLATION
2.1 Inspection
The equipment should be inspected for damage that may have occurred during shipment. All damage should
be reported to the shipping agent. If the equipment is damaged to the extent that faulty operation may result,
contact De Nora Water Technologies before installation. Always reference the complete instrument serial
number and model number in all correspondence concerning the equipment supplied.
2.2 Location and Mounting
The Model 17CA3000 Chloralert™ Plus Receiver may be wall-mounted close to the gas sensor(s) or may be
located up to 1000 feet from the sensor(s). Refer to Figure 2-3 for the recommended interconnection diagram.
Mounting-ears are supplied with the Receiver and the Sensor/Transmitter and may be used for convenient
wall-mounting (Refer to Figures 2-1 and 2-2 respectively). The mounting ears may be oriented in several
directions to facilitate convenient mounting. It is recommended that both receiver and sensor/transmitter
be oriented vertically as shown in Figure 1-1. Mounting screws or any other mounting hardware desired or
required is supplied by the customer.
The receiver case is supplied, configured with three ½-NPT conduit fittings for customer wiring (Refer to
Figure 2-1). The receiver enclosure contains four additional knockouts for attachment of additional conduit
fittings. These provide a means of wiring optional features like digital communications, analog outputs, battery
backup and alarms.
Select a location which gives limited access to unauthorized personnel and where ambient temperature remains
within the temperature range specified in section 1.3. The installation area should be well
ventilated and provided with a source of heat, if necessary, to ensure that the ambient temperature does not
fall below the specified minimum temperature.
The selected location must be of sufficient size to provide necessary equipment clearances and to allow easy
access for routine inspection and maintenance of the Chloralert Plus Receiver and its gas sensor/transmitters.
Refer to Figures 2-1 and 2-2 for outline dimensions of the Chloralert™ Plus Receiver and Sensor/Transmitter
Assembly respectively.
Locate the sensor module 12" to 36" (305 to 915 mm) from the floor with the sensor pointed downward.
2.3 Receiver Electrical Connections
