The instrument range is from 0 to 5000 mNTU. The instrument is
guaranteed to meet specifications relative to accuracy, repeatability and
linearity up to 5000 mNTU. The instrument will still show a value above
5000 mNTU to the level of 5500 mNTU, but above 5000 mNTU,
measurement performance is not guaranteed. Between 5000 and
5500 mNTU, the warning alarm will flash to tell the operator that the
operating range has been exceeded. An over-range event is also logged.
All alarm setpoints are calculated based on the maximum value show
(5500 mNTU).

Precautionary labels

Read all labels and tags attached to the instrument. Personal injury or
damage to the instrument could occur if not observed. A symbol, if noted
on the instrument, will be included with a danger or caution statement in
the manual.

This symbol, if noted on the instrument, references the instruction
manual for operation and/or safety information.

Electrical equipment marked with this symbol may not be disposed of
in European public disposal systems after 12 August of 2005. In
conformity with European local and national regulations (EU Directive
2002/98/EC), European electrical equipment users must now return
old or end-of-life equipment to the Producer for disposal at no charge
to the user.

Note: For return for recycling, please contact the equipment producer or supplier
for instructions on how to return end-of-life equipment, producer-supplied
electrical accessories, and all auxillary items for proper disposal.

This symbol indicates that a risk of electrical shock and/or
electrocution exists.

This symbol indicates the need for protective eye wear.

This symbol indicates a laser device is used in the equipment.

This symbol, when noted on the product, identifies the location of a
fuse or current limiting device.

This symbol indicates that the marked item requires a protective earth
connection. If not provided with a plug on a cord, connect positive
earth to this terminal (U.S. cord set provides ground).

Certification

Canadian Radio Interference-Causing Equipment Regulation,
IECS-003, Class A:

Supporting test records reside with the manufacturer.

This Class A digital apparatus meets all requirements of the Canadian
Interference-Causing Equipment Regulations.

Cet appareil numèrique de la classe A respecte toutes les exigences du
Rëglement sur le matériel brouilleur du Canada.

FCC Part 15, Class "A" Limits

Supporting test records reside with the manufacturer. The device
complies with Part 15 of the FCC Rules. Operation is subject to the
following conditions:

1. The equipment may not cause harmful interference.

2. The equipment must accept any interference received, including

interference that may cause undesired operation.

Changes or modifications to this equipment not expressly approved by
the party responsible for compliance could void the user's authority to
operate the equipment. This equipment has been tested and found to
comply with the limits for a Class A digital device, pursuant to Part 15 of
the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses and can

radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference
to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference, in which case the user will be
required to correct the interference at their expense. The following
techniques can be used to reduce interference problems:

1. Disconnect the equipment from its power source to verify that it is or

is not the source of the interference.

2. If the equipment is connected to the same outlet as the device

experiencing interference, connect the equipment to a different
outlet.

3. Move the equipment away from the device receiving the interference.

4. Reposition the receiving antenna for the device receiving the

interference.

5. Try combinations of the above.

Product overview

D A N G E R

Chemical or biological hazards. If this instrument is used to monitor a
treatment process and/or chemical feed system for which there are
regulatory limits and monitoring requirements related to public health,
public safety, food or beverage manufacture or processing, it is the
responsibility of the user of this instrument to know and abide by any
applicable regulation and to have sufficient and appropriate
mechanisms in place for compliance with applicable regulations in the
event of malfunction of the instrument.

Although the sc controller is certified for Class 1, Division 2 Hazardous Locations,
it is only certified when installed with sensors listed in Control Drawings 5860078.
The sc controller and FT660 sc are NOT suitable for use in Class 1, Division
2 Hazardous Locations.

The FT660 sc is a continuous-reading instrument for filter management
(Figure 1). The FT660 sc is appropriate for ultra pure and all processes
that include clean water monitoring.

The status light on the head assembly is illuminated when an error
occurs and flashes when a warning occurs or the head assembly is not
installed correctly.

The back of the head assembly has a molded "lip" that may be used to
hang the head on the edge of the body of the instrument during
maintenance.

Installation

D A N G E R

Multiple hazards. Only qualified personnel must conduct the tasks
described in this section of the document.

Installation guidelines

N O T I C E

High internal temperatures will damage the instrument components.

• Do not operate the instrument in direct sunlight or next to a heat
source.

Install the instrument indoors in a clean environment with minimum

•
vibration.

Note: Particulate contamination from the surrounding area is a major cause of
error.

• Install the instrument level.

• Keep the flow rate and operating temperature as constant as possible
for best performance.

Mechanical installation

Instrument mounting

Install this instrument on a flat, vertical surface. Refer to the illustrated
steps in Figure 3. Mounting hardware (two ¼-20 bolts) is supplied by the
customer.

Install the instrument as near to the sampling point as possible to
minimize lag time of the sample flow.

Refer to Figure 4 for instrument dimensions and clearance
specifications.

Note: As an alternative, this instrument can be installed on the optional floor stand.
