IN-WARRANTY RETURN MATERIAL PROCEDURE
Compressor
Copeland Refrigeration Corporation has stocking wholesalers who main-
tain a stock of replacement compressors and service parts to serve
refrigeration contractors and servicemen.
When a compressor fails in warranty, contact your local sales represen-
tative,
or McQuay Warranty Claims Department at the address on the
cover of this bulletin. You will be authorized to exchange the de-
fective compressor at a Copeland Wholesaler, or an advance replace-
ment can be obtained. A salvage credit is issued to you by the whole-
saler on the returned compressor after Copeland factory inspection of
the inoperative compressor. Provide McQuay with full details and in-
voices and we w i l l reimburse the difference. In this transaction, be
certain that the compressor is definitely defective. If a compressor
is received from the field that tests satisfactorily, a service charge
plus a transportation charge will be charged against its original cre-
dit value.
On all out-of-warranty compressor failures, Copeland offers the same
field facilities for service and/or replacement as described above.
The credit issued by Copeland on the returned compressor will be deter-
mined by the repair charge established for that particular unit.
Components Other Than Compressors
Material may not be returned except by permission of authorized fac-
tory service personnel of McQuay, Inc., at Mpls., MN. A "Return
Goods"
tag will be sent to be included with the returned material.

handling at our factories and prompt issuance of credits.

ber,

transportation charges prepaid.
APPENDIX
STANDARD CONTROLS
Oil Pressure Safety Control
The oil pressure safety control is a manually resettable device which
senses the differential between oil pressure at the discharge of the
compressor oil pump and suction pressure inside the compressor crank-
case. When the oil pressure reaches approximately 15 PSI above the
crankcase suction pressure,
the pressure actuated contact of the con-
trol opens from its normally closed position. If this pressure dif-
ferential cannot be developed, the contact will remain closed and
energize a heater element within the control. The heater element
warms a normally closed bimetallic contact and causes the contact to
open de-energizing a safety relay and breaking power to the compres-
sor.
