INSTALLATION
The
H34 is designed to be 26 3/4" from grade to hose connection outlet. The casing
extends 12" below grade. The water supply line should be installed below
the local frost line. Connect the H34 to the supply line with a schedule 40
galvanized riser pipe and Schedule 40 galvanized coupling. The Schedule 40 riser
pipe and coupling are necessary to provide support for the H34 hydrant and to
allow heat conduction to prevent freezing.
The
electrical connection for the heater shall be made in accordance with local and
state electrical codes. The source of power shall be protected with a circuit
breaker in accordance with local and state electrical codes.
For convenient
maintenance, a shut off valve ahead of each hydrant is recommended.
WARNING:
FLUSH THE SUPPLY LINE BEFORE CONNECTING THE HYDRANT.
With
the hydrant completely assembled, make the connection to the supply line,
tightening with a pipe wrench on the pipe casing.
MAINTENANCE
To
remove heater assembly from the hydrant:
-
Turn
off electrical power.
-
Turn
off water supply
-
Open
valve to release internal pressure
-
Disconnect
electrical connection at the hydrant.
-
Remove
tow set screws (#16) from heater cover
-
Remove
heater cover (#13) while feeding electric cable through the outlet.
-
Remove
brass compression nut (#14) at top of the hydrant head.
-
Pull
the heater assembly (#17) out of the top of the hydrant.
To
install new heater assembly:
-
Slide
compression nut (#14) and compression sleeve (#15) over heater tube.
-
Insert
the heater assembly (#17) into the to of the hydrant.
-
Tighten
compression nut (#14) finger tight.
-
Slide
heater assembly (#17) into the hydrant until 1/2" of the metal tube
remains exposed above the compression nut (#14).
-
Tighten
the compression nut (#14).
-
Turn
on the water supply and check for leaks. If necessary, retighten the
compression nut.
-
Feed
the electric cable through the heater cover outlet and guide the thermostat
into the cover while installing the heater cover.
-
Install
and tighten two set screws for the heater cover.
-
Make
proper electrical connections at the hydrant.
-
Turn
on electric power.
TROUBLESHOOTING
To
verify heater operation:
-
Flow
water through hydrant until the water and hydrant temperature is below 70o
F. The hydrant should feel cold to the touch.
-
Verify
that electric power is on.
-
Verify
that electric power is present at the heater connection
-
The
heater should be drawing about 1/2 ampere current. Use an appropriate AC
current meter to verify that current flow is present.
-
Alternately:
the heater will stay on until it has heated the water (and hydrant) to
approximately 90o F. The hydrant should feel warm to the touch.
FREEZE
WARNING
FOR
WINTER USE: Electrical power must be provided for the heater assembly to
operate properly and prevent the hydrant from freezing. With proper installation
and operation this hydrant will be freeze-proof where the frost depth does not
exceed 7 feet and where air temperatures reach -20o F.
