JL/JLR Meter Installation Instructions:
1. Flush the line thoroughly after plumbing changes to eliminate the possibility of foreign materials reaching the meter.
2. Operating pressure is 35 to 150 psi.
3. Install meter horizontally with the register facing up and the inlet port facing the supply water line.
4. It is recommended that if there is any possibility that the water supply contains foreign materials, a Carlon strainer should be installed between the supply and the meter.
5. It is not recommended that the meter be run for long periods of time at the maximum rating as excess wear will result and the life of the meter will be greatly reduced.
6. To reduce potential harmful effects to equipment from water hammers caused by quick closing valves, it is suggested that you purchase and install a Carlon slow-closing solenoid valve.
7. Protect the meter from freezing and from heat in excess of 105°F.
8. Protect meter from any backflow of water opposite of indicated flow direction.
9. For outdoor installation, protect the meter and remote counter from direct exposure to the elements.
Recommended straight unobstructed pipe sections:
a. 10X pipe diameter before the meter on the inlet side and 5X the diameter on the outlet side of the meter.
b. Valves(check, gate, etc.) = 12X Diameter of pipe
c. Two bends or one tee and one bend or bends at random = 25X Diameter of pipe
NOTE: The “JLR” Remote style meter is not recommended for installation in meter pits or outdoors.
JLR – OVR Wiring Instructions
1. Install the meter in line as prescribed by local code. Note: The JL OVR meter should be installed in a location protected from harmful elements, ie water, snow, direct sunlight, dirt and dust. Carlon does not recommend that this model be installed in pits
2. Remove cover from remote counter.
3. Cut vinyl jacket away from wire approx. 1″ from end and strip each lead to expose 1/2″ of wire and crimp
4. Loosen terminal screws on base and insert under terminal screws and tighten (It is not necessary to observe any polarity or color coding. Cover Terminals with silicone sealant to protect from moisture.)
5. Mount base of remote counter to wall (Note reading on counter). Remote counter may be installed up to 1000′ from meter.
6. Pick up leads at meter. Touch each lead to a terminal of a 9-volt battery for not more than one second this will advance the remote counter one count. Repeat if desired. Then check remote counter to be sure circuit is complete. If remote counter has not advanced, check cable and terminal screws. Screws should be tight and cable should not have any staples through it. (Please note: remote counter cannot be reset to zero.)
7. At the meter, remove terminal cover. This exposes the terminals.
8. Cut vinyl jacket approximately 1″ from end of wire and strip each to expose 1/2″ of wire and crimp on stakon. Insert stakon under terminal screws and tighten. (It is not necessary to observe any polarity or color coding.)
9. Install remote counter cover with seal pin.
10. Replace cover with vinyl cable extending through slot at bottom and seal.
