NITRO VALVE INSTALLATION
AND OPERATION
Important: Flush the supply lines completely before installing valves.
A.For threaded models wrap male adapters with 2 wraps of Teflon tape
and thread the adapters into the valve inlet and outlet 1 turn past hand
 tight. CAUTION: Over tightening may cause damage to the valve.
B.For slip models apply a thin coating of solvent cement to the outside
 of the supply line and the valve inlet. Twist the valve fully onto the
 supply line to evenly spread the cement. Repeat these steps for the
 outlet connection. The solenoid must be on the downstream side of
 the connection.
C.For barbed models slip one or two clamps over the poly pipe. Slip the
 poly pipe completely over the barbed outlet. Clamp the poly pipe
 securely to the barb.
D.Using watertight connectors, connect the valve common and an
 individual station wire to the solenoid leads.
E. Flush the laterals by opening the internal manual bleed lever on the
 downstream side of the solenoid. Turn the flow control stem fully open
 (counterclockwise) for flow control models.
F. Close the internal manual bleed after flushing the system.

Problem
Valve will not open
manually
Valve will not open
electrically
Valve will not close
Slow leak through
sprinklers
Solution
Check water supply and any possible master or
gate valves to insure they are open.
Check that valve is installed with the arrow
pointing in the downstream direction.
Check that the flow control is fully open
(counterclockwise).
Turn off the water supply. Remove the solenoid
and check for debris blocking the exhaust port.
Turn off the water supply. Remove the cover.
Inspect the diaphragm for damage and replace
if necessary.
Check voltage at controller for 24 VAC to station.
Check voltage across the solenoid lead wires for
minimum 21 VAC.
If the valve still does not operate electrically
replace the solenoid with a Weathermatic model
M24E solenoid.
Insure the manual bleed lever is in the closed
position.
Check for leaks around flow control, solenoid or
between valve cover and body.
Turn off the water supply. Remove the solenoid
and check for debris or damage to the exhaust
port.
Turn off the water supply. Remove valve cover
and inspect for debris under diaphragm or debris
in diaphragm ports
Check for dirt or gravel embedded in diaphragm
seat.
Check actuator and exhaust fitting for proper
seating.
