5. ANTI - SIPHON VALVE INSTALLATION
The BTC-ASV can be installed directly to PVC pipe with two PVC male
adapters (not included). Inlet 3⁄4 in. FNPT, outlet 3⁄4 in. FNPT.
Rated operating pressure: 10 to 125 PSI
Recommended operating pressure: 10 to 80 PSI
NOTE: The BTC-ASV must be installed at least 6 in. higher than the
highest sprinkler head on the system or back-drainage may occur.
Additional control valves must not be installed downstream of the
anti-siphon valve. The valve must not be operated continuously for
more than 12 hours in any 24-hour period. Consult local codes for
specific details.
1. Flush main line until water runs clear before installation.
2. Shut off main water supply.
3. Install the anti-siphon valve directly to PVC pipe using 3⁄4 in. PVC
male adapters (Figure 5a and 5b) or use 3/4 in. schedule 80 nipple.
The arrow on valve body indicates direction of water flow.
NOTE: Wrap all fittings with Teflon tape. Do not use pipe cement on
the valve as this will damage the valve and void the warranty. Make
sure when wrapping fittings with Teflon tape that no excess gets into
the internal assembly. Tighten the fittings with a wrench, but do not
over tighten.
4. Turn the main water supply on and pressurize the system.
5. To test the BTC-ASV, press the button on the unit. A click will be
heard, indicating the valve is open. Check that the system is
operating correctly and press the button again to turn it off.
A second click will be heard indicating that the valve closed.
6. The unit is now ready to be programmed.
