sufficiently covered for the purchaser's
purpose, the matter should be referred
to the manufacturer.

and conditions of The Trane Company.
The warranty is void if the equipment
is repaired or modified without the
written approval of the manufacturer, if
the operating limits are exceeded or if
the control system or the electrical
wiring is modified.  Damage due to
misuse, lack of maintenance or failure
to comply with the manufacturer's
instructions or recommendations are
not covered by the warranty obligation.

Notify the carrier immediately by phone

Installation

This manual covers the installation,
operation and maintenance of the

designed to incorporate a single slab
coil assembly, improved application
flexibility, servicing and maintenance
accessibility and an improved
accessory line.

LWHAs are specially designed to meet
tight ceiling space requirement.

Note:

"Warnings" and "Cautions" appear at
appropriate places in this manual.
Your personal safety and the proper
operation of this machine require that

Handling

The unit will be supplied with a
