NOTICE!
No mixing valve will work satisfactorily if improperly installed. We suggest, therefore, that you read
these instructions carefully before installing and follow directions as outlined. Handle the mixing valve with care.
The Lawler Series 67 Water Temperature Controller has been carefully assembled and tested at the factory and
set to deliver water at any temperature within the control range stamped on the label. At each inlet of the controller
is a union angle combination stop and check valve with strainer which should be turned open in operation.
CAUTION: When maintaining and adjusting the
mixing valve, all fixtures should be isolated from
use. Lawler Manufacturing Co., Inc. recommends
that you work safely at all times and in a manner
consistent with the OSHA Lock/Tagout standard,
29 CFR 1910.147 and other applicable standards.
This installation & maintenance manual covers all
configurations of the Series 67.
