5. Try combinations of the above.

2.2 Product overview

General information
The PHOSPHAX sc LR is a one-channel analyzer that measures ortho-phosphate ions
3—
(PO
) in waste water and surface water. The analyzer does not measure diphosphates
4
or polyphosphates. The measuring principle is based on the Vanadat-Molybdat method, also known as the Yellow method.
The analyzer is used with an SC Controller. The measured value shows on the controller display as PO4–P (default) or PO
3—
.
4
There are two analyzer models available:
• PHOSPHAX sc LR: weather-resistant enclosure for outdoor installation
• PHOSPHAX indoor sc LR: for indoor installation
The reagents and standards necessary for the chemical analysis are internally installed in the analyzer enclosure. The analyzer uses pumps, valves and syringes to move the sample and reagents to the measuring cell on the analytics panel. When the measurement cycle is complete, the analyzer discards the sample through the drain line. The analyzer can automatically do cleaning cycles and calibrations for better measurement performance. Refer to Figure 1.
The sample must be prepared and filtered before analysis. Refer to Sample requirements on page 4. Based on the system configuration, one or two analyzers can connect to a FILTRAX instrument for filtration (or an applicable sample feed) and measure one or two parameters. Refer to System configuration options on page 16.

Section 3 Installation

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

3.1 Installation guidelines

Install the instrument:
• As near the sample source as possible to decrease analysis delay
• In a clean, dry, well ventilated and temperature controlled location
• In a location with minimum vibrations that has no direct exposure to sunlight
• In an environmental enclosure that supplies protection from precipitation and direct sunlight, good ventilation and temperature control if installed outdoors
• In a location where the power switch and power cord are visible and easily accessible
• In a location where there is sufficient clearance around it to make plumbing and electrical connections

3.2 Mechanical installation

3.2.1 Attach the instrument to a wall

Risk of injury or death. Make sure that the wall mounting is able to hold 4 times the weight of the equipment.
D A N G E R
D A N G E R
C A U T I O N
Personal injury hazard. Instruments or components are heavy. Use assistance to install or move.
The object is heavy. Make sure that the instrument is securely attached to a wall, table or floor for a safe operation.
Attach the instrument upright and level on a flat, vertical surface. Keep a minimum clearance of 813 mm (32 in.) in front of the instrument to open the door. Refer to Figure 3. Mounting hardware is supplied by the user. Make sure that the fastening has sufficient load bearing capacity (approximately 160 kg). The wall plugs must be selected and approved to suit the properties of the wall. Refer to the illustrated steps that follow.
For rail mount and stand mount installations, refer to the documentation supplied with the mounting hardware.

3.3 Electrical connectors and plumbing access ports

Figure 6 shows the electrical connectors and fittings on the instrument. Use the tubing
plug to put tubing or cables through the analyzer access ports. To keep the environmental rating of the enclosure, make sure that there is a sealing plug in the access ports that are not used.
Refer to System configuration options on page 16 to find the correct plumbing installation.

3.4 Plumbing

D A N G E R
Fire hazard. This product is not designed for use with flammable liquids.
N O T I C E
Do not install reagents until all plumbing is complete.
Make sure to use the specified tubing size.

3.4.1 Sample line guidelines

Select a good, representative sampling point for the best instrument performance. The sample must be representative of the entire system.
To prevent erratic readings:
• Collect samples from locations that are sufficiently distant from points of chemical additions to the process stream.
5
Use the sealing plug to close access ports that are not used.
15
Installation
• Make sure that the samples are sufficiently mixed.
• Make sure that all chemical reactions are complete.

3.4.2 Drain line guidelines

Correct installation of the drain lines is important to make sure that all of the liquid is removed from the instrument. Incorrect installation can cause liquid to go back into the instrument and cause damage.
• Make the drain lines as short as possible.
• Make sure that the drain lines have a constant slope down.
• Make sure that the drain lines do not have sharp bends and are not pinched.
• Make sure that the drain lines are open to air and are at zero pressure.

3.4.3 Tubing considerations

Plan cable and tubing path to prevent sharp bends and tripping hazards. The analyzer uses different tubing types for plumbing connections. The type of tubing is based on the analyzer configuration:
• Ø 3.2 mm: sample line tubing
• Ø 6 mm: unheated drain tubing
• Ø 22 mm: heated drain tubing
Always put the drain tubing so that there is a continuous fall (minimum 3°) and the outlet is open to air (not pressurized). Make sure the drain tubing is less than 2 meters (6.56 ft).

3.5 System configuration options

Before plumbing or electrical installation, find the correct system configuration option based on the number of analyzers, sample filtration, drain line and number of measured parameters6. Refer to Table 3.
