5.0 Maintenance
5.1
Every six months, lubricate the lever with light mo-
tor oil as shown to the right.
5.2
Since the “LT” valve is a safety device, test it regu-
larly for proper functioning. Interrupt electrical
power to simulate an unsafe condition.
If the valve
does not close immediately, remove it from service
and replace.
4.1
Check valve nameplate to make certain electrical
characteristics correspond with electrical service be-
ing used.
4.2
All wiring connections should be made in accor-
dance with local or regional electric codes.
4.3
All internal wiring is connected at the factory to a
terminal block included in the built-in wiring
compartment of the valve (see figure 4). Make all
field connections to this terminal block. Strip the
wire 1/4" to 3/8". Insert into the terminal open-
ing and tighten the screws. Check for loose
strands that may cause a short.
4.4
Wiring diagrams for the latching solenoid and
microswitch(es) are located on the inside surface of
the terminal block cover, and also in Figure 4.
4.5
The operator has two 1/2" threaded conduit con-
nections for field wiring. Use wiring suitable for 75°
C operation.
4.6
For raintight applications, wiring connections to the
valve must be made with 90° close ell rigid conduit
fittings. The conduit should travel downwards
from the valve to cause water to flow away from the
valve.

Replacement of Solenoid & Bracket Assembly
(See Fig. 5 Page 4)
6.1
Remove main housing cover and gasket.
6.2
Remove the wiring box cover. Disconnect solenoid
lead wires from the terminal block.
6.3
Remove the three 10-32 machine screws holding the
cast solenoid bracket and microswitch bracket to the
operator housing. Remove both brackets.
6.4
Mount the new solenoid and bracket assembly in the
operator housing, replace the microswitch bracket,
replace the three 10-32 screws, reconnect lead wires,
and install main and side gaskets and covers.
