INSTALLATION

SECTION 2.0

INSTALLATION

2.1UNPACKING AND INSPECTION. Inspect the out- side of the carton for any damage. If damage is detect- ed, contact the carrier immediately. Inspect the instru- ment and hardware. Make sure all the items in the pack- ing list are present and in good condition. Notify the fac- tory if any part is missing. If the sensor appears to be in satisfactory condition, proceed to Section 2.2, Mounting.

NOTE

Save the original packing cartons and mate- rials as most carriers require proof of dam- age due to mishandling, etc. Also, if it is nec- essary to return the instrument to the facto- ry, you must pack the instrument in the same manner as it was received. Refer to Section 6 for return instructions. If the sensor is to be stored, the vinyl boot should be filled with pH buffer solution and replaced on sensor tip until ready to use.

WARNING

Glass electrode must be wetted at all times (in storage and in line) to maximize sensor life.

2.2MOUNTING. Each sensor has been designed to be located in industrial process environments. Temperature and pressure limitations must not be exceeded at any time. A caution or warning label regarding this matter is attached to each sensor. For insertion, transfer the label as shown on label instruc- tions. See Figure 2-2. For submersion applications, first note limits then remove and discard label.

NOTE

Before mounting the sensor, shake down the sensor to remove any air bubbles that may be present at the tip of the pH glass bulb. In most cases, the pH sensor can sim- ply be installed as shipped and readings with an accuracy of ±0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the sensor must be calibrated as a loop with its compatible ana- lyzer or transmitter.

2.2.1Flow Through and Insertion Mounting for Models 396, 396VP, 398, and 398VP. The Models 396, 396VP, 398, and 398VP Sensors can be used with a 1 inch MNPT process connector at the front of the sensor for mounting into a 1-1/2 inch tee or the process. See Figure 2-1 for installation configurations.

2.2.2Submersion Mounting for Models 396, 396VP, 398, and 398VP. The Models 396, 396VP, 398, and 398VP Sensors also have a 1 inch MNPT process con- nector available for use on the back of the sensor. Tapered pipe threads in plastic fittings tend to loosen after installation. It is therefore recommended that Teflon tape be used on the threads and that the tightness of the connection be checked frequently to assure that no loos- ening has occurred. To prevent rain water or condensa- tion from running into the sensor, a weatherproof junc- tion box is recommended (see Figure 2-4). The sensor cable must be run through a protective conduit for isola- tion from electrical interference or physical abuse from the process. The sensor should be installed within 80° of vertical, with the electrode facing down. The sensor’s cable should not be run with power or control wiring.

2.2.3Quik-Loc Mounting for Model 397. The Quik- Loc mounting is used with the Model 397 TUpH sen- sor only.

SAFETY WARNING

It is recommended that a thermometer, drain valve to relieve pressure and pres-sure gauge be inserted near the Quik-Loc assembly (see Figure 2-5).

WARNING

Once the Quik-Loc unit is installed the oper- ator should wait for the process to cool to a safe temperature, use the pressure drain valve to relieve all process pressure and observe the pressure on the pressure gauge for proper removal of the sensor without spray or bodily injury. The Quik-Loc kit used with the 397 TUpH sensor is not recom- mended for use with hazardous, corrosive, or strong oxidizing chemicals due to a risk of spray or bodily injury.
