1. RECEIVING EQUIPMENT
On receipt of your equipment it is suggested that you
visually check for external damage to the carton. If the
carton is damaged, it is suggested that a note be made
on the Bill of Lading when signing for equipment. Remove
the heater from the carton and if it is damaged report the
damage to the carrier immediately. Be sure that you
receive the number of packages indicated on the Bill of
Lading. Claims for shortages and damages must be
filed with carrier by consignee.
Purchased parts are subject to replacement only
under the manufacturer's warranty. Debits for defective
replacement parts will not be accepted and defective
parts will be replaced in kind only per our standard
warranties.
When ordering parts, you must specify Model and
Serial Number of the heater. When ordering under
warranty conditions, you must also specify date of
installation.
Raypak recommends that this manual be re-
viewed thoroughly before installing your Raypak
Heater. If there are any questions which this manual
does not answer, please contact your local Raypak
