INSTALLATION, OPERATION AND MAINTENANCE MANUAL

1.0 ABOUT THE MANUAL

This manual has been prepared as an aid and

guide for personnel involved in installation and

maintenance. All instructions must be read and

understood thoroughly before attempting any

installation, operation, or maintenance.

WARNING

Always wear safety glasses when installing,

servicing or operating a threaded sight window.

Failure to follow any instruction could possibly

result in a malfunction of the threaded sight

window or glass breakage with resulting sudden

release of pressure causing serious personal

injury or property damage.

2.0 INTRODUCTION

Penberthy Threaded Sight Windows can be

used anywhere that a ¼" to 3" piping "T" or a

female NPT exists. Threaded Sight Windows

offer a quick and inexpensive method of

observing a fluid.

At a glance, the Threaded Sight Window allows

for monitoring of:

• Liquid presence - change in level or volume

of liquid in the viewing area

• Liquid color - change in tint or hue

• Liquid clarity - change in opacity, brightness

or purity

The Threaded Sight Window provides a circular

glass window for convenient fluid monitoring.

The window assists the operation manager by

creating a monitoring port for fluid process

volumes, directions, and reactions without

exposing the liquid to the external environment.

The Threaded Sight Window is recommended

for applications less than or equal to 285 psig

(1.97 MPaG).

3.0 AVAILABLE MODELS

Standard materials of construction for the

WTSL metal housings are carbon steel and

stainless steel. Standard glass is tempered

borosilicate with neoprene gasketing being

the standard gasket for steel and Teflon

for

316STS.

2.1 System Description

The Penberthy Threaded Sight Window consists

of four basic components. Each component

may vary slightly, depending on the desired

physical and mechanical properties for the

window. Use the exploded parts view in

Section12.0 as additional reference material.

Cover: the cover provides a machined surface

in which the glass and cushion are protectively

seated. The threaded cover provides an

effective means of "screw" compressing the

glass between the cover and body.

Body: the threaded body provides rigid, in-line

or vessel attachment capability. In addition, the

body provides a flat, machined cavity in which

the cover compresses the gasket.

Glass: the glass provides a window for in-line

or vessel fluid observation.

Gaskets: the gaskets are compressed by the

cover to tightly seal the gap between the glass

and the body to prevent leaking.

5.0 INSTALLATION

CAUTION

Only qualified, experienced personnel who

are familiar with sight window equipment and

thoroughly understand the implications of the

tables and all the instructions should install

the Threaded Sight Window. Failure to read and

comply to the following instructions could result

in serious personal injury or property damage.

INSPECTION

1. Examine the glass to see that it is free of

scratches, chips or other imperfections.

2. Ensure that the body and cover have been

cleaned and are free of any foreign material.

3. Ensure that the vessel connection has been

cleaned and is free of any foreign material.

4. Wrap the external male thread with Teflon

tape before installing the sight window.

LOCATION PRECAUTIONS:

Locate the Threaded Sight Window:

• where it can be easily seen;

• away from areas where objects may be

dropped, thrown, or generally allowed to

contact the glass;

• so that it is protected from dust, grit, or other

objects that could damage the glass;

• so it is protected from external thermal

shock, such as a high temperature

application being exposed to a cold air blast

or a cold water wash.

COVER TORQUE CHECK:

Cover torque is vital to the proper operation

of a Threaded Sight Window. Cover torque

should be checked after initial installation, and

periodically thereafter, to ensure that the unit is

in compliance with the torque values described

in Section 4.1.

WARNING

Failure to inspect, locate and check the sight

window as described above within the Inspection,

Loading Precautions and Cover Torque Sections

may result in serious personal injury and property

damage.

WARNING

Torquing under pressure increases the likelihood

of the glass breaking and contents spraying out

of the vessel. A sight window in service must be

freed of all pressure or vacuum, allowed to reach

ambient temperature and drained or purged of

all fluids before re-torquing. Failure to follow this

procedure could result in severe personal injury

and property damage.

PENBERTHY THREADED SIGHT WINDOWS

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

6.0 OPERATION

Before initializing sight window operation,

check that all installation procedures have been

completed. Use only qualified, experienced

personnel who are familiar with sight window

equipment and thoroughly understand

the implications of the tables and all the

instructions. Check that cover has been torqued

to its proper limit as stated in Section 4.0.

Check that all connections are pressure tight

and the glass is clean and free of any damage.

WARNING

Sight windows should be brought into service

slowly to avoid excessive shock or stress on the

glass. Rapid pressurization of a sight window

can cause glass breakage with resulting sudden

release of pressure, causing serious personal

injury or property damage.

7.1 Maintenance Procedures

Glass should be given regular and careful

attention. Keep glass clean using a commercial

glass cleaner and a soft cloth. Inspect the

surface of the glass for any signs of clouding,

etching, scratching or physical damage such

as bruises, checks or corrosion. Glass that is

damaged is weakened and may break under

pressure. Shining a light at approximately a

45° angle will aid in detecting some of these

conditions. Typical damaged areas will glisten

more brightly than the surrounding glass

because the light is reflected.

Detection of any damage, problem areas or any

surface wear is sufficient evidence to take the

sight window out of service. DO NOT proceed

with operations until the glass has been

replaced with a glass replacement kit following

the Disassembly/Reassembly instructions in

Section 8.0.

Gasket Leaks must be repaired immediately.

DO NOT proceed with operations until

gaskets have been replaced by following the

Disassembly/Reassembly instructions in

Section 8.0.

Connection Leaks should be corrected by

tightening the NPT/hex connection. If this fails

to stop the leaking, take the sight window out

of service, wrap the male threads with Teflon

tape, and re-install the sight window into its

operating location.

Corrosion may occur if the user has selected

an improper material for the Threaded Sight

Window application. It is the responsibility of

the user to choose a material of construction

compatible with both the contained fluid

and surrounding environment. If internal or

external corrosion are present, an investigation

must immediately be performed by the user.

It may be necessary to contact an authorized

Penberthy distributor to better determine the

origin of the corrosion.

7.0 MAINTENANCE

Use only qualified, experienced personnel who

are familiar with sight window equipment and

thoroughly understand the implications of the

tables and all the instructions.

Create a maintenance schedule for each

specific installation of a Threaded Sight

Window. On all inspections, regularly check the

following items:

1. glass, for cleanliness and signs of damage

or wear,

2. sight window for signs of leakage at gaskets

or connections,

3. sight window, for signs of internal or

external corrosion, and

4. cover torque values (see Section 4.0).

WARNING

DO NOT proceed with any maintenance while the

sight window is in operation. Pressure increases

the likelihood of the glass breaking and contents

spraying out of the vessel. A sight window in

service must be freed of all pressure or vacuum,

allowed to reach ambient temperature and

drained or purged of all fluids before conducting

maintenance. Failure to follow this procedure

could result in severe personal injury and property

damage.

7.2 Troubleshooting

Problem: Glass becomes etched or clouded in

service.

Cause: Fluid being handled is not compatible

with the glass material.

Solution: Replace the glass and/or shield.

Problem: Glass continually breaks in service.

Cause: Warped body as a result of

mechanical or thermal stresses.

Solution: Reduce the stress and replace sight

window.

PENBERTHY THREADED SIGHT WINDOWS

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

8.0 REMOVAL-DISASSEMBLY-REASSEMBLY

WARNING

DO NOT proceed with any removal or disassembly

while the sight window is in operation. Pressure

increases the likelihood of the glass breaking

and contents spraying out of the vessel. A sight

window in service must be freed of all pressure or

vacuum, allowed to reach ambient temperature

and drained or purged of all fluids before

proceeding. Failure to follow this procedure could

result in severe personal injury and property

damage.

8.1 Disassembly

The Threaded Sight Window should be

disassembled by loosening the cover with a

spanner wrench as denoted in Section 4.0.

Remove the cover, washer, cushion, glass, and

gasket from the indicator using the appropriate

safety precautions. Once a sight window has

been disassembled, all glass must be disposed

of because of wear; and, all gaskets and

cushions must be disposed of since they are

permanently deformed by compression during

service.

SAFETY INSTRUCTIONS

DO NOT under any circumstances re-use glass

or gaskets previously in service, since they can

cause leaks or high stress points resulting in

glass breakage and severe personal and property

damage. Glass that is broken is dangerous

and should be disposed of in a safe manner

determined by the user.

8.2 Reassembly

To prepare for installation of new glass, clean

the gasket seating surfaces in the body and

cover. This should be done using a soft metal

scraper (preferably brass) to remove all burrs,

rust, and remnants of the previous gasket.

Exercise extreme care to avoid gouging or

scarring gasket seating surfaces. Failure to

prepare the gasket surfaces will result in leaks

and/or glass breakage.

9.0 DISPOSAL AT END OF USEFUL LIFE

Penberthy Threaded Sight Windows are used in

a variety of fluid applications. By following the

appropriate federal and industry regulations,

the user must determine the extent of

preparation and treatment the Sight Window

must incur before its disposal. A Material Safety

Data Sheet (MSDS) may be required before

disposal services accept certain components.

Metal, glass and polymers should be recycled

whenever possible. Refer to order and Emerson

Material Specification sheets for materials of

construction.

10.0 TELEPHONE ASSISTANCE

If you are having difficulty with your Sight

Flow Indicator, contact your local Penberthy

distributor. You may also contact the factory

information (in addition to that above) is

needed:

Reason for return

Person to contact at your company

"Ship To” address

There is a minimum charge for evaluation

of non-warranty units. You will be contacted

before any repairs are initiated should the cost

exceed the minimum charge. If you return a

unit under warranty, but is not defective, the

minimum charge will apply.

Check flatness of each glass seating surface

of the sight window by using a known flat piece

the same size as the glass and a thickness

gage. Surfaces must be flat within 0.005 inch

(0.13 mm). If the glass seating surface can’t

be restored to this tolerance, the entire sight

window must be disposed of and replaced. If

tolerances are met, proceed with reassembly of

the sight window.

Before installation, inspect the replacement

glass for imperfections. During inspection,

and during any subsequent handling of

glass, keep the glass from contacting other

surfaces. Bumping or sliding of glass against

other surfaces can result in glass breaking,

scratching, or chipping. Install the new glass by

following the procedure in Section 4.0.
