Water & Electrical Supply: (DIAGRAM 2.)
The water line and electrical feed should be brought to the waterer location below the frost penetration depth for your area. If feeding several waterers
off one water line then a larger diameter supply should be used. An 8" diameter clay casement tile or other suitable enclosure should be used to bring
the supplies up from below the frost line and through the center of the pad.
DO NOT FILL THE ENCLOSURE WITH INSULATION-LEAVE IT OPEN.
The tile should be cut off at 2" above the pad and the water supply at 10”
for the H50, H100, H200, P50 and P100 models; 3” for the HL50 and P25 models. A shut-off valve inside the waterer is recommended. As an extra
precaution a thermostatic heating cable (or heat tape) can be installed along the supply riser pipe to prevent freeze-up. A fused receptacle located
inside the waterer is provided for plugging in the cable. Also recommended is 2" rigid foam insulation against the concrete inside the unit.
Water Supply Connections:
After the bowl is mounted to the pad the bowl should be swung open by removing the pin, clearing the latch and swinging the bowl open. A 1/2" inner
diameter flexible hose is provided for connecting to the supply.

Electrical Supply Connections: (DIAGRAM 3.)
Electrical connections should be made by a qualified electrician following local codes. It is recommended that each waterer be connected through a
dedicated supply line to prevent stray voltage from other equipment on nondedicated lines. Connections should be made to a 120 volt supply. A ground
fault interrupter circuit breaker is recommended for extra safety. The H100 models draw 500 watts/4.2 amps and the H50/HL50/HLW-P50 models
draw 300 watts/2.7 amps. The P25 model draws 190 watts/1.7 amps and the H200 models draw 820 watts/6.4 amps. If using a cable heater the
amp draw must be added to determine the circuit breaker capacity required. To make the connections remove the front cover. (Inside bowl on the P25,
P50 and P100 models) Remove the insulation block. This is where the wiring diagram is located. Bring the supply through the back of the box using
an appropriate connector. Connect the black live lead to the blue and black stripped leads taped together and the white neutral to the stripped white
and black leads. The ground wire should be securely attached to the ground lug provided in the box.

Adjusting the Water Level: (DIAGRAM 4.)
To adjust the water level, remove the valve/float cover assembly by removing the four nuts and lift the cover straight up and off. The level is factory
preset but differences in water pressure will cause variation. Adjust the float by loosening the wing nut on the valve and moving the arm upwards to
raise water level and downwards to lower the water level. Start with a low water level first, then adjust float arm upwards until required level is reached.
