Endwall Installation Manual

This instructional manual provides “General Installation Instruction.” Installers should refer to

the "as-built" shop drawings for specific guidance as it relates to your system. For additional

information, contact Major Industries.


MAJOR INDUSTRIES, INC. / 888-759-2678 / 715-842-4616 / WWW.MAJORSKYLIGHTS.COM

INTRODUCTION

Quality installation in a timely manner requires

careful attention to planning and detail. We need

your help to ensure a successful weather-tight

installation.

We produce our custom-fabricated daylighting

products to precise dimensions under factory-

controlled conditions. Everything has been checked

and verified to meet shop drawings and the

architectural requirements. Your job is perhaps the

most important step yet to be completed. Our

analysis of warranty claims indicates that over 85%

of all field complaints are the result of improper

installation or - equally damaging - an improper

assembly during installation. All Major Industries

daylighting products are designed as a system - you

must assemble the parts and pieces in exact

sequence. Any effort to “freelance” or do it in a new

way risks our common goal of ensuring weather-

tightness and owner satisfaction.

Finally, our warranty commitment sold with this job

is predicated on satisfactory site conditions. Please

take the time to perform a thorough site audit prior

to starting your installation, and ask yourself the

following questions before installation. If even one

of them is false, you are almost guaranteed to have a

less than optimal installation.

UNLOADING

Unloading should be organized to minimize material

handling. If hoisting is required by either crane or

forklift, the skylight’s weight should be evenly

distributed to prevent distorting or damaging the

material. Use only approved nylon lift slings that are

in good condition and sized to the load. Crates are

for shipping purposes only and should not be relied

upon for hoisting or storage.

INSPECTION

Upon receipt, inspect the shipment to ensure that

materials were not damaged during shipping. If

damage is visible or suspected, note it on the bill of

lading and contact Major Industries as soon as

possible. Count material and check it immediately

against the packing list. If there is a shortage, note it

on the bill of lading and contact Major immediately.

STORAGE

While a single panel easily withstands exposure to

sunlight and the elements, a stack of panels will trap

heat and moisture, causing clouding in the panels.

To avoid this irreversible effect, panels must be

stored in a dry, shaded, well-ventilated area. Skids

should be elevated at one end by wood spacers. It is

the installer’s responsibility to protect materials until

they are installed - unless otherwise specified. When

placing materials on the roof, it is the installer’s

responsibility to make sure roofing materials are not

damaged. Failure to comply with recommended

storage procedures will negatively affect the

warranty on the panels.

INSTALLATION NOTES

Major Industries does not recommend walking on

the panels. If the installer must walk on the panels,

the panel surface MUST be protected by applying a

layer of foam carpet padding over the panel surface,

followed by a sheet of plywood or other similar

smooth material to distribute weight.

It is the installer’s responsibility to correctly install

and seal the entire unit. Always install only a

quantity of panels that can be fully protected with

glazing caps at the end of the day. Glazing panels are

not designed to be left unprotected from the

weather. Water damage during installation is not

covered by warranty. Always remember that water

can be drawn up into the skylight due to negative

interior building pressure. Properly clean all building

surfaces to be caulked with approved cleaning

solutions. Make sure caulking and sealants make

uniform contact with all surfaces being sealed. It is

important that all necessary sealants and caulking

are properly applied. Installers need to verify with

the sealant supplier and manufacturer as to the

proper sealant type required for the application.

Failure to do so may cause the system to fail, causing

possible interior damage.

The installer must have the sign-off sheet (supplied

with the Major Industries purchase order) signed by

the job site superintendent before leaving the job

site. No payments will be released to the contractor

until this sign-off sheet is forwarded to Major.

These instructions have been supplied to assist with

installation. They are correct to the best of our

knowledge - however, no warranty is expressed or

implied. Each installation is unique and attention

must be given to the approved shop drawings

supplied specifically for this project. Any

modifications require factory approval. Major

Industries expects its installers to be knowledgable

and complete all work professionally and to industry

standards.

DAMAGE WARNING

Do not attempt to weld or cut any materials near an

installed skylight or wall system. Damage may occur

to the panel from flames, hot metal or sparks unless

they are fully protected by fireproof material.

We want our installers and customers to have the

best daylighting system possible, and we encourage

you to call us with your questions and concerns.

Major's experienced personnel can troubleshoot the

problem and help you choose the best option.

to confirm that they meet system and weather requirements of +0.25/-0 inches.

o True o False

2. All masonry/EIPS is in place for wall openings and single-ply membranes have been applied to roof curbs. (7 out

of 10 installations “leak” when this recommended installation sequence is reversed. Major will not provide an

unconditional warranty if we are forced to install our product before other responsible trades complete site
