Installation and Operation of: Foodwarmers

RECEIVING AND INSPECTION OF THE EQUIPMENT

Even though most equipment is shipped boxed or crated, care should be taken during unloading so the 
equipment is not damaged while being moved into the building.
Carefully check for any visible signs of damage to the cartons or containers.  If evidence of damage exists, 
the package should be opened immediately and a joint inventory and examination of the contents should 
be made by you and the driver.

CONCEALED DAMAGE

If a concealed loss or damage is discovered after you have given the carrier a clear delivery receipt, notify 
the carrier in writing immediately or within ten (10) days from the delivery date. If you phone the carrier, you 
must follow up the call in writing to protect your rights. You can only improve your position as a 
claimant by promptly reporting such loss or damage. You should also retain all cartons or containers, 
including packing material, until an inspection has been made or waived.

FILING A CLAIM

Notation of loss or damage does not constitute the filing of a claim. You should file your claim in writing with 
the carrier immediately!
Carriers will furnish the necessary form upon request. You should also request an inspection. If a claim is filed 
by phone, always follow up immediately in writing.
