Receiving and Handling
Upon receiving the equipment, check for both obvious
and hidden damage. Check to be sure that all parts of
the shipment, including accessories, are accounted
for.
Storage
If a temperature interlock must be stored prior
to installation, it must be protected from dirt and
moisture. Indoor storage is recommended. For
outdoor storage, cover the control package with
a tarp to keep it clean, dry, and protected from UV
(ultraviolet) radiation damage.
Improper storage which results in damage to the unit
will void the warranty.
