VC1000, VC6000 Series
REPLACEMENT CARTRIDGES FOR 2-WAY & 3-WAY VC VALVES
INSTALLATION
CAUTION
1. Read these instructions carefully. Failure to follow
them could damage the product of cause a
hazardous condition.
2. Always conduct a thorough checkout when
installation is completed.
3. Installer must be a trained and experienced service
technician.
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.
These valves are only for use in cold, warm, and
hot water applications. They are designed for a
medium temperature range from 34 to 203 °F
(1 to 95 °C), at a maximum pressure of 300 psig
(20 bar). They are to be operated with the
appropriate Resideo actuators only. Water must
be properly filtered, treated and conditioned
according to local conditions.
The presence of suspended particulate(s) in the
system, such as detached calcium scale, sand, silt,
large quantities of magnetite, etc., can affect
operation of the valve. For trouble-free operation of
this product, good installation practice should
include initial system flushing, chemical water
treatment, and the use of a 50 micron (or finer),
10% system side-stream filter(s). Remove all filters
before flushing.
If removed cartridges have been jamming due to
particulate build-up, Resideo recommends using
flush caps, part no. 27286B to flush the system
before replacing cartridges.
Put the VC actuator manual lever in the fully up
position of the half open (down) position to allow
initial system flushing with the actuator mounted.
This may be done without electrical hook-up.
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).
IMPORTANT
The presence of iron oxide (red rust) in the system
voids the valve warranty.
