Honeywell VCA Series User manual

The VC hydronic valve consists of a valve body and replaceable characterized
cartridge assembly.
Depending on the valve model selected, they can be used with a VC2114 or
VC8114 series actuator to provide on-off flow control, or with a VC6930 or
VC7930 series actuator to provide proportional flow control. Two way bodies
may be plumbed in either direction. Three-way bodies may be used in either
diverting or mixing applications.
Replacing the cartridge rebuilds the valve. The valve body should be able to
stay in the pipes indefinitely.
VC actuators, ordered separately, use cam-operated cartridge travel to resist
water hammer. Limit switches prevent motor overrun. These actuators are
available with conformal coated printed circuit boards for humidity resistance.

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 and experienced service technician.
4. Always conduct a thorough check-out 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
of the four orientations to suit the most convenient wiring direction.
Actuator latching mechanism works only when the lengths of the
actuator and the valve body are parallel to each other.
6. An extra 1" (25 mm) head clearance above the actuator, is required
to remove the actuator.
PLUMBING
The valve may be plumbed in any angle, including vertical piping, but
preferably not with the actuator below horizontal level of the body.
Make sure there is enough room around the actuator for servicing or
replacement.
For use in diverting applications, the valve is installed with the flow
water entering through bottom port AB, and diverting through end ports
A or B. In mixing applications the valve is installed with inlet to A or B
and outlet through AB.
Mount the valve directly in the tube or pipe. Do not grip the actuator
while making and tightening up plumbing connections. Either hold
valve body in your hand or attach adjustable spanner (38 mm or 1-1/2")
across hexagonal or flat faces on the valve body (Figure 4).
3
If assembling valve train on a bench, take care not to deform body with
vice. Do not place the raised "H" logo between the jaws of the vice.
Excess jaw force can deform the body.
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 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 cartidge 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. See Figure 5.
3. Replace valve actuator.
TO REPLACE CARTRIDGE (IF REQUIRED)
Two-way cartridges fit all two-way bodies. The Cv rating of a valve can
be changed by replacing the cartridge, allowing for unique
combinations. Three-way cartridges fit all three-way bodies.
1. Disconnect power supply before servicing to avoid electrical shock or
equipment damage.
2. Depending on the installtion, it may be necessary to disconnect leadwires
to valve actuator, or depress tab on Molex™connector and remove.
Where appropriate, label wires for rewiring.
3. Remove valve actuator by pressing up on the latch mechanism located
directly below the red manual open lever with thumb (See Figure 5).
Simultaneously press the actuator down towards the valve body with
moderate hand force and turn the actuator counter-clockwise by 1/8
turn (45°). Lift actuator off the valve body.
!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 (or finer)
system
side stream filter(s). Remove all filters before
flushing.
Put the VC actuator manual lever in the 3-way actuator fully up
position 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).
CAUTION:
Disconnect power supply before connecting wiring to prevent
electrical shock and equipment damage.
On 24V systems, never jumper the valve coil terminals, even
temporarily. This may damage the thermostat.

4. To replace a cartridge, isolate flow to the valve using installed shut off
valves or other service equipment designed for this purpose. Remove old
cartridge with 40007029-002 wrench supplied with the replacement unit.
It
may be necessary to use pliers or other tools to remove the old cartridge
due to calcium or dirt buildup in the valve body.
5. Clean the valve surfaces marked *and ** in Figure 6 to ensure the new
cartridge O-rings seal at these points. Use care to avoid damage to these
surfaces ( ** for 3-way valves only).
6. Remove the pre-lubricated cartridge assembly from its plastic bag.
Thread it by hand into the valve body and tighten it down with the
enclosed wrench until it bottoms out. DO NOT OVER TIGHTEN:
maximum torque is 40 in-lb. [4.5 Nm]. The top surface of the cartridge
should be flush with the top edge of the body casting.
7. Replace valve actuator by following the procedure in the "To Install Actuator"
below.
8. Reconnect leadwires or Molex™connector if necessary.
9. Refill hydronic system or restore system flow by opening isolating valves.
10. Restore power, and checkout operation of cartridge in valve, making sure
of no internal seat leakage or external body leakage.
Restore system pressure slowly to the valve to allow any trapped air to
escape. Check for leaks. Re-install the actuator.
TO INSTALL 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. Wiring may be done either before or after the actuator is installed.
Refer to the VC Actuator Installation and Instruction sheet for detailed
wiring and check-out instructions.
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 lock will click
when engaged (See Figure 7).
NOTE: The actuator can also be installed at right angles to the valve
body but in this position the lock mechanism will not engage.
2. Connect leadwires.
3. Restore power and check operations.

SERVICE
This valve should be serviced by a trained, experienced service
technician.
1. If the valve is leaking, drain system OR isolate valve from the
system. Do not remove valve body from plumbing.
2. Check to see if the cartridge needs to be replaced.
3. If the motor or other internal parts of the actuator is damaged,
replace the entire actuator assembly.
NOTE: Honeywell VC series hydronic valves are designed and tested
for silent operation in properly designed and installed systems.
However, water noises may occur as a result of excessive water
velocity. Piping noises may also occur in high temperature (over
212oF [100oC]) systems with insufficient water pressure.
