NSPECTION

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

The furnace must be carefully inspected 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.
3. With concealed damage, carrier must be notified as soon as

possible -  preferably within five days.

4. File the claim with the following support documents within a nine month statute of limitations.

Original or certified copy of the Bill of Lading, or indemnity bond.

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.

RECAUTIONS

NOTE:

  Discharge your body’s static electricity before touching unit.  An electrostatic discharge can adversely affect electrical

components.

Use the following precautions during furnace installation and servicing to protect the integrated control module from damage.  By
putting the furnace, the control, and the person at the same electrostatic potential, these steps will help avoid exposing the
integrated control module to electrostatic discharge.  This procedure is applicable to both installed and non-installed (ungrounded)
furnaces.

1. Disconnect all power to the furnace.  Do not touch the integrated control module or any wire connected to the control prior  to

discharging your body’s electrostatic  charge to ground.

2. Firmly touch a clean, unpainted, metal surface of the furnaces near the control.  Any tools held in a  person’s hand during

grounding will be discharged.
