Use only the low temperature solder specified. Failure to follow
these instructions could result in property damage and/or moder-
ate personal injury.
WARNING: Solder joints will fail if used at pressures or tem-
peratures above those listed in the above table. Do not
exceed the temperature and pressure limitations. Failure to follow
the above instruction can cause the joint to fail resulting in serious
personal injury and/or property damage.
WARNING: Hazardous conditions could occur if the follow-
ing notes are not adhered to:
WARNING NOTES:
READ PRIOR TO INSTALLING COMFORT-TROL
1. Do not install Comfort-Trol in a dusty area or in an area where
the flow of air to the operator is restricted because erratic
operation or premature failure may occur.
2. Use 95-5 (Tin-Antimony) solder and a good grad of flux to
solder the Comfort-Trol valve body into the system.
NOTE: a. Remove the brass bonnet and retainer assembly
from the valve body before applying heat to the
body. Failure to do so will damage the valve seals
and discs.
b. Excessive use of solder in a vertical installation may
result in damage to the valve seat.
c. Avoid excessive use of flux.
d. Heat associated with the use of silver solder may
damage the Comfort-Trol.
3. Do not install a jumper wire between terminals #1 and #2
because the thermostat heat anticipator may burn out when
the Comfort-Trol operator is energized.
4. Keep external wiring from contacting the Comfort-Trol operator
cover by securing the wiring to a nearby support.
5. Use only silicone grease to lubricate the valve gland pin and
O-ring seals. Do not use lubricants with a petroleum base. The
use of a petroleum base lubricant will cause swelling and fail-
ure of U-rings.
6. Do not insulate the Comfort-Trol Zone Valve Operator.
7. Use of additives to the system may be harmful to the Comfort-Trol.
Failure to follow these instructions could result in serious personal
injury or death and property damage.
