SECTION I - FOREWORD
As is the case with any fi ne piece of equipment, care
must be taken to provide the proper attention to the op-
eration and maintenance detail of this machine.
This manual of instructions along with Digital Control
System User Manual (for systems with optional DDC
controls) has been prepared in order for you to become
well-acquainted with those details, and in doing so, you
will be able to give your Indirect Gas-Fired System the
care and attention which any piece of equipment needs
and deserves.
It is the customer and installation personnel
responsibilty to determine if the unit is equipped
with all of the safety devices required for the par-
ticular application. Safety considerations include
the accessibility of the unit to non-service person-
nel, the provision of electrical lockout switches,
maintenance procedures and automatic control
sequences. Clearly mark any shutoff devices.

* IMPORTANT NOTICE *
Applied Air assumes no responsibility for loss or dam-
age in transit; therefore, you should protect yourself
by following these instructions. Failure to do so is your
responsibility.
BILL OF LADING
Save your bill of lading. It is a contract, and you will need
it, provided you have to fi le a loss or damage claim. Re-
member, claims are outlawed after nine months.
LOSS IN TRANSIT
Before you sign for this shipment, check against the bill
of lading, also the transportation company's delivery
ticket. Make sure that you get the exact total of articles
listed. Should the delivery ticket show more or less
items than you are offered, then the carrier's agent must
mark the difference on your freight bill before you sign.
VISIBLE DAMAGE IN TRANSIT
If something is damaged, accept the shipment only
if the carrier's agent places a notation on your freight
bill explaining the nature and extent of damage. Upon
inspection of article, make claim to the delivering carrier.
CONCEALED DAMAGE IN TRANSIT
Sometimes transit damage is not noticed until the goods
are unpacked. In such cases, notifi cation to the carrier
must be made within fi fteen (15) days of receipt of ship-
ment. In such cases, save the packages and packing
material, then notify the transportation company at once,
and request an inspection. When the inspector calls,
have him make out and leave a "concealed" bad order
report. He is obliged to give one to you. Insist on it.
DISPOSITION OF DAMAGED ARTICLES
Never return damaged articles to us. They are the prop-
erty of the transportation company when the claim is
fi lled. They will give you disposition instructions.
PACKING
We comply with the packing requirements of the trans-
portation companies, and your bill of lading proved that
everything was in good condition when shipped. That
bill of lading contract requires them to deliver in perfect
condition.
