needed).
3. To avoid the possibility of activating no flow alarm, set flow meter to desired liter
flow prior to turning unit off.

plate assembly from the center section.
4. Carefully pull out assembly and disconnect the power cord wire connections from
the hourmeter (white) and circuit breaker (black).
5. From the back of unit, completely pull power cord out of holder and unwrap the
power cord wires from the ferrite bead (ring). Please note configuration of wires
around the ferrite ring at this time. Do not dispose ring.

Power Cord Installation
To install a new power cord, follow the steps below.
1. Place both new power cord and old power cord together (side-by-side) to
determine location to install strain relief on new power cord.
2. Route both wire ends of new power cord into entry location on the base of unit
and pull power cord through hole to the pre-determined location to install strain
relief to new power cord.
3. Install strain relief onto power cord and secure power cord to base.
4. Locate ferrite ring and insert both wire leads from new power cord into the center
of ferrite ring so that the outside insulation of power cord is flush with the inside
rim of ferrite ring.
5. Continue to wrap both power cord wires around and through the center of ferrite
ring 6 times. (The last few times will require wires to be inserted individually
one at a time into center of ferrite ring.)
6. Insert power cord into holding clamps located to the right of the left sieve bed,
and route the power cord to the inside of the top left sieve bed tubing connection.
7. Reconnect the white wire from power cord to the hour meter and the black wire
from power cord to the circuit breaker.
8. Reinstall right mounting plate assembly to center section using a Phillips-head
screwdriver.
9. When properly installed, ferrite ring should be located in the recessed area behind
the right mounting plate assembly.
