PLUMBING
Refer to the VC Series Cartridge Valve Installation and Instruction
sheet, form number 95C-10919, for plumbing instructions.
MANUAL OPENER
The manual opener can be manipulated only when in the up position. The
motorized valve can be opened by firmly pushing the red manual lever
down to midway and in. This holds the valve in the open position. This
"manual open" position may be used for filling, venting, draining the
system or for opening the valve in case of power failure. The valve can
be restored manually to the closed position by depressing the red manual
lever lightly and then pulling the lever out. The valve and actuator will
return to the automatic position when power is restored.
NOTE: If the valve is powered open (the lever is down), it can not be
manually closed unless actuator is removed.

CAUTION:
Disconnect power supply before connecting wiring to prevent
electrical shock and equipment damage.
On 24 V systems, never jumper the valve coil terminals, even
temporarily. This may damage the thermostat.
INSTALLATION
WHEN INSTALLING THIS PRODUCT:
1. Read these instructions carefully. Failure to follow them could damage
the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on the product to make
sure the product is suitable for your application.
3. Installer must be a trained, experienced service technician.
4. Always conduct a thorough checkout when installation is completed.
5. While not necessary to remove the actuator from the body, it can be
removed for ease of installation. The actuator can be installed in any
position to suit the most convenient wiring mode.
6. An extra 1" (25 mm) head clearance is required to remove the actuator.
TO INSTALL ACTUATOR
Installation of the actuator does not require draining the system,
provided the valve body and valve cartridge assembly remain in the
pipeline. Wiring may be done either before or after the actuator is
installed.
1. The actuator head is automatically latched to the valve. Align the
coupling hole in the bottom of the actuator with the valve stem.
Press the actuator down towards the body with moderate hand force
and turn the actuator counter-clockwise by 1/8 turn (45 degrees) to
line up the actuator with the piping. The latch will click when
engaged. See Figure 2.
NOTE: The actuator can also be installed at right angles to the valve
body but in this position the latch mechanism will not engage.

2. Connect leadwires. See Figure 3 for flexible conduit installation
with plenum-cable models.
WIRING
NOTE: Each 3-wire (SPDT) actuator must have individual spdt control-
ler. Use series 40 or 80 for single controller to control multiple valves.
Figures 4, 5, 6 and 7 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
boltage 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.
CAUTION:
Disconnect power supply before connecting wiring to prevent
electrical shock and equipment damage.
IMPORTANT:
For trouble-free operation of the product, good installation
practice must include initial system flushing, chemical
water treatment, and the use of a 50 micron (preferably 5
micron) 10% side stream system filter(s). Remove all
filter(s) before flushing. Limit flow through the filter to
5~10% of total system flow to prevent 'starving' the
system. Ensure filter cartridge is changed frequently
enough to prevent clogging.
Put the VC actuator manual lever in the manual open or the
fully open (down) position to allow initial system flushing with
the actuator mounted. This may be done without electrical
hook-up. Alternatively, reusable flush caps, part # 272866B,
may be purchased separately for use in initial flushing of dirty
hydronic systems.
Do not use boiler additives, solder flux and wetted
materials which are petroleum based or contain mineral
oil, hydrocarbons, or ethylene glycol acetate. Compounds
which can be used, with minimum 50% water dilution, are
diethylene glycol, ethylene glycol, and propylene glycol
(antifreeze solutions).
