NOTICE!
Thermostatic Water Controllers will not work satisfactorily if improperly installed.
Read these instructions carefully before installing and follow directions as outlined.
Checking Cold Water Shut-Off
Turn on full hot and cold water supply to the valve
and let it run for one minute. Then shut off the hot
water stop and check valve only. Cold water should
flow through the controller momentarily then be re-
duced to a negligible amount.
Failure to do so indicates that:
a. Plunger is sticking and requires cleaning or
replacement.
at the outlet temperature stamped on the label.
Standard setting is 110°F. If the outlet temperature
is different than that shown on the label, readjust
valve according to “TEMPERATURE ADJUST-
MENT” procedure on page 2.
2. If after adjusting the outlet temperature the wa-
ter stays below the set temperature, see “CHECK-
ING COLD WATER SHUT-OFF.” If the tem-
perature stays above the set temperature, see
“CHECKING HOT WATER SHUT-OFF.”
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.
WARNING: Opening of the actuator may result in
electrical shock.
General Description
The Model 805 water temperature controller is care-
fully assembled and tested at the factory to mix hot
and cold water to any desired temperature within
range. The temperature of the hot water should be
at least 20°F higher than the maximum valve setting.
The major safety features are:
1. Failure of cold water supply causes the hot water
ports to reduce hot water flow.
2. Failure of hot water supply causes the cold water
ports to reduce cold water flow.
3. Failure of the thermostat allows both ports to
reduce flow of hot and cold water.
At each inlet of the controller is a union end stop and
check valve with removable strainer. Stop and check
valves are to prevent water from bypassing between
hot and cold water supply lines. These valves should
be fully open when in operation.
Maximum Inlet Conditions
Pressure: 125 psi
Temperature: 200°F
Maintenance
The controller should be checked periodically and,
if needed, cleaned as outlined in “INSPECTING and
CLEANING VALVE.” To test for proper setting and
operation - proceed as follows:
1. Turn on full hot and cold water supply to the
valve. The mixing valve should deliver water
