One-Year Warranty of Entire Conditioner— McQuay Inter-
national, hereinafter referred to as the “Company,” warrants
to the original owner that the entire Incremental Comfort
Conditioner is free from defects in material and workman-
ship. Any part or portion thereof which becomes defective
under normal use during the period of this warranty will be
repaired or replaced provided the Company’s examination
shall prove to its satisfaction that the part was or became
defective under normal use. This warranty contemplates that
first year maintenance labor was arranged for with the
installer or otherwise at the time the conditioner was pur-
chased or installed. The Company’s obligations under this
warranty are limited to: (a) Repairing the defective part or (b)
Furnishing a replacement part provided the defective part is
returned to the factory, transportation charges prepaid. No
reimbursement will be made for expenses incurred in making
field adjustments or replacements unless specifically autho-
rized in writing by the Company.

This warranty constitutes the buyer’s sole remedy. It

is given in lieu of all other warranties. There is no implied
warranty of merchantability or fitness for a particular
purpose. In no event and under no circumstance shall the
Company be liable for incidental or consequential dam-
ages, whether the theory be breach of this or any other
warranty, negligence, or strict tort.

No person (including any agent, salesman, dealer or

distributor) has  authority to expand the Company’s obliga-
tion beyond the terms of this express warranty, or to state
that the performance of the product is other than that
published by the Company.

One Year Refrigeration Circuit Warranty — Hermetically
sealed motor-compressor assemblies and all components

of refrigeration circuits not readily separable therefrom are
warranted to the original owner for one year. Refrigerating
circuits consist of the motor-compressor assembly evapora-
tor coil, condenser coil and interconnecting tubing. Repairs
under this warranty will be made at the Company’s expense
provided that the refrigerating circuit is delivered without
shipping damage, transportation prepaid to the factory or to
a factory designated repair station, at the Company’s option.
This one-year warranty does not include any other parts of
the equipment such as filters, fans, fan motors, controls,
cabinet parts, electrical relays, capacitors, protective de-
vices, or wiring. The Company is not obligated under this
warranty for field labor such as service for inspection, remov-
ing, packing and/or reinstalling the refrigeration circuit, nor
for return transportation charges.

General Conditions — The above warranties are void if the
Company’s equipment has been damaged, misused, sub-
jected to abnormal use or service or its serial number has
been altered, defaced or removed, or payment for the equip-
ment is in default. The Company is not responsible for
service to correct conditions due to misapplication, im-
proper installation, inadequate wiring, incorrect voltage con-
ditions or unauthorized opening of the refrigeration circuit,
nor for consequential damages. In case the Company’s
equipment is installed in conjunction with cabinets, grilles,
louvers, controls or other parts manufactured by others,
these warranties shall apply only to the Company manufac-
tured portion of the equipment. The conditions of the war-
ranty plan are effective for eighteen (18)  months from date of
factory shipment. The Company reserves the right to make
a handling and inspection charge in the case of parts or
equipment improperly returned as defective and/or as being
in warranty.

COOL button. Move the thermostat control to the extreme
cooling position (clockwise). The compressor should cycle

neither the heater nor the compressor should continue to
operate.

Note: The direction of the conditioned air may be adjusted by
rotation of discharge grilles to change airflow pattern in a
room. The building superintendent or manager should be
requested to make any changes, as a thin flat-edged tool is
required to move grille.
