4.7 NOZZLE INSTALLATION
The nozzle is simply screwed onto the monitor’s exit threads. If the nozzle is installed on a Hurricane RC (with electric motors) assure
that the nozzle’s actuator does not make contact with the horizontal drive motor housing when the monitor is in its lowest elevation
position.
4.7.1 ER NOZZLE INSTALLATION ORIENTATION
For nozzles with electric pattern control, a waterproof connector wire is provided at the
bottom outlet of the Hurricane RC’s control station box. This wire attaches directly to
TFT’s electric Masterstream 1250 nozzle. The electric actuator box of nozzle must be
oriented to the top side of nozzle for the connection wire to extend 90° above horizontal
and 45° below elevation movement.
Monitor Electrical Controls Supplemental Instructions (LIY-500) for properly attaching
female to male connectors). Any other nozzle should have the corresponding male
electrical connector installed and long enough wire to extend 90° above horizontal and
45° below elevation movement of the nozzle.
4.8 PRESSURE GAUGE PORT
There is a ¼” NPT female threaded hole behind the elevation handwheel
. The hole is plugged from the factory. If a
pressure gauge is desired, unscrew the plug and install the gage using pipe sealant. Make sure the gauge does not interfere with
operation.
4.9 AUTOMATIC DRAIN
An automatic drain is included to empty water from a low point in the monitor piping to prevent
freezing and help empty hose lines. The valve is designed to close automatically when pressure in
the monitor exceeds approximately 5 psi, and open again when the pressure drops to that point.
The automatic drain may be disabled if not desired for your application.
To disable the drain valve:
1. Unscrew the drain assembly and remove the screw and washer.
2. Flip over the rubber drain valve so the raised edge is against the face of the housing.
3. Reassemble the screw and washer using blue Loctite, and reinstall the drain valve assembly.
A secondary drain valve should be installed the monitor’s inlet piping to drain water in the riser.
CAUTION
Mismatched or damaged waterway connections may cause equipment to leak or uncouple under
pressure. Failure could result in injury. Equipment must be mated to matched connections.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability to
uncouple the connection, or complete loss of engagement over time. Failure could cause injury. Per
NFPA 1962, if dissimilar metals are left coupled together, an anti-corrosive lubricant should be
applied to the connection and the coupling should be disconnected and inspected at least
quarterly.
NOTICE
TFT’s Masterstream 1250 ER nozzle’s electric actuator box must be on the top side. Align the
actuator body and the waterway body to as shown.
NOTICE
DO NOT cut off the female connector on the monitor. This connector is molded onto the wire and
must remain intact to maintain the water tightness of the electrical system.
WARNING
Monitors, valves, and piping may be damaged if frozen while containing sufficient amounts of
water. Such damage may be difficult to detect visually and can lead to possible damage, injury, or
death. Equipment that may be exposed to freezing conditions must be drained immediately
following use to prevent damage.
CAUTION
Structural damage from corrosion can result from failure to drain appliance between uses. Damage
from corrosion can cause injury due to equipment failure. Always drain appliance between uses.
