COMPRESSION MODELS
For compression fitted models, tighten the compression nuts enough
to make a watertight seal. TAKE CARE NOT TO OVER TIGHTEN.
Maximum torque limit is 33 ft-lb for the 22 mm compression fitting,
and 48 ft-lb for the 28 mm compression fitting.
SWEAT MODELS
On sweat fitted valves, the cartridge is shipped loose to avoid being
damaged during the solder operation.
1. Remove valve actuator from body and solder the connecting pipes
in accordance with normal soldering practices.
2. After soldering and valve has cooled, remove cartridge assembly
from plastic bag, insert into the valve body and tighten down with
enclosed wrench until it bottoms out. DO NOT OVER TIGHTEN
(maximum torque is 40 in-lb). The top surface of the cartridge will
be flush with the top edge of the body casting.
3. Replace valve actuator.
TO INSTALL REPLACEMENT ACTUATOR
NOTE: Installation of a new actuator does not require draining
the system provided the valve body and valve cartridge
assembly remain in the pipeline.
1. Check replacement part number and voltage ratings for match with
old device.
2. Disconnect power supply before servicing to avoid electrical shock
or equipment damage.
3. Disconnect leadwires to actuator, or depress tab on Molex™
connector and remove. Where appropriate, label wires for rewiring.
4. The actuator head is automatically latched to the valve. To remove,
press up on the latch mechanism located directly below the red
manual open lever with thumb (See Figure 3 below). Simultane­
ously press the actuator down towards the body with moderate
hand force and turn the actuator counter-clockwise by 1/8 turn (45
degrees). Lift the actuator off the valve body.
NOTE: The actuator can also be installed at right angles to the
valve body but in this position the latch mechanism is not engaged.
5. Install the new actuator by reversing the process in (4).
6. Reconnect leadwires or Molex™ connector.
7. Restore power, and checkout operation.

WIRING
NOTE: Each 3-wire (SPDT) actuator must have individual SPDT controller.
Use series 40 or 80 for single controller to control multiple valves.
VC2114 and VC8114 actuators must be used with separately­
powered (hardwired) electronic controllers. Their sustained current
draw is too low for power stealing (parasitic power) thermostats
or series anticipators of electromechanical thermostats.
Figures 4A,4B,5A,5B show wiring connections. Port "A" open and
closed denote valve open and closed positions respectively. On auxiliary
switch models, terminal 4 (grey wire) contact makes at the end of the Port A
opening stroke. On Molex™ connector models, valve & auxiliary switch
voltage must be the same to meet approval requirement. For mixed line
voltage and 24 Vac (Safety Extra Low Voltage) application, the cable
version is recommended. auxiliary switch voltages must be the same to
meet approval requirement. For mixed line voltage and 24 Vac (Safety Extra
Low Voltage) application, the cable assembly version is recommended.
