9. Apply Teflon tape or pipe thread sealant on tapered
pipe thread ends of the meter couplings on 3/4", 1" or
1 1/2" models.
10. Air trapped in the Flowmeter should be removed
prior to operation. To accomplish this, loosen the meter
couplings slightly (for models so equipped) and rotate
the Flowmeter slowly so that register is upside down.
Open upstream (inlet) valve slowly letting water through
the meter. Rotate Flowmeter slowly again until the
register is upright and tighten meter couplings. The
Flowmeter is now ready for cable connection to the
Remote Programmable Divider.
B. REMOTE PROGRAMMABLE DIVIDER
1. The Remote Programmable Divider may be located up
to 100 feet from the Flowmeter. The unit has molded-in 4
mounting holes that will accept 1/4" diameter screws for
wall mounting.
2. Once the Remote Programmable Divider and the
Flowmeter have been installed, connect the cable from
the Flowmeter to the programmable divider by plugging
the connector on the cable into the receptacle on the
programmable divider.
CONNECTOR INSTALLATION
C. METERING PUMP
1. Installation of your LMI metering pump should be in
accordance with instructions included with the pump.
2. Plug the connector from the programmable divider into
the receptacle located on the bottom of the pump’s
control panel.
3. To prime the pump, switch to the INTERNAL mode
and follow the PRIMING PROCEDURES on the LIQUID
END ASSEMBLY INSTRUCTION SHEET. Once the
pump is primed, switch to the EXTERNAL mode for
meter pacing.
4. Set divider number on the programmable divider
according to instruction in the next section.
5. Check treated water for desired dosage.
6. Adjust stroke length knob until desired dosage is
obtained.
IMPORTANT:
PUMP MUST BE IN THE EXTERNAL MODE FOR
METER PACING.
