INSTALLATION INSTRUCTIONS

A

TTENTION INSTALLING PERSONNEL

As a professional installer, you have an obligation to know
the product better than the customer . This includes all safety
precautions and related items.

Prior to actual installation, thoroughly familiarize yourself
with this Instruction Manual. Pay special attention to all
safety warnings. Often during installation or repair, it is
possible to place yourself in a position which is more haz­ardous than when the unit is in operation.

Remember, it is your responsibility to install the product
safely and to know it well enough to be able to instruct a
customer in its safe use.

Safety is a matter of common sense...a matter of thinking
before acting. Most dealers have a list of specific good safety
practices...follow them.

The precautions listed in this Installation Manual are intended
as supplemental to existing practices. However, if there is
a direct conflict between existing practices and the con­tent of this manual, the precautions listed here take prece­dence.

S

AFETY PRECAUTIONS

The following symbols and labels are used throughout this
manual to indicate immediate or potential safety hazards.
It is the owner’s and installer’s responsibility to read and
comply with all safety information and instructions accom­panying these symbols. Failure to heed safety information
increases the risk of personal injury , property damage, and/
or product damage.

All units are securely packed in shipping containers tested
according to International Safe Transit Association specifi­cations. The carton must be checked upon arrival for ex­ternal damage. If damage is found, a request for inspec­tion by carrier’s agent must be made in writing immedi­ately.

Inspect the kit carefully on arrival for damage and bolts or
screws which may have come loose in transit. In the event
of damage the consignee should:

1. Make a notation on delivery receipt of any visible
damage to shipment or container.

2. Notify carrier promptly and request an inspection.

• Original paid freight bill or indemnity in lieu thereof.

• Original or certified copy of the invoice, showing
trade and other discounts or reductions.

• Copy of the inspection report issued by carrier’s
representative at the time damage is reported to
carrier.

The carrier is responsible for making prompt inspection of
damage and for a thorough investigation of each claim. The
distributor or manufacturer will not accept claims from deal­ers for transportation damage.

NOTE: When installing in a garage, the element MUST

be at least 18” above the floor.
