15.0 SYSTEM FILL PROCEDURE

15.1 Filling The Reservoir Tank

The CS-1 has been designed to fill the reservoir tank using either of two

methods: gravity fill or pumped fill. NOTE: This is not a self-priming pump.

Manual prime or fill the reservoir for prime.

NOTE: Never leave the unit unattended when filling the system or tank. Running

the pump dry, without liquid, will damage pump seals and possibly damage pump

impeller. Follow the steps below:

15.1.1 Gravity Fill:

1. Turn off and isolate the electrical supply to the unit.

2. Close supply isolation valve.

3. Connect the antifreeze supply container to the supply isolation valve.

A flexible hose may be used, but must not restrict the flow from the

supply container to the valve. An additional isolation valve must be

installed in the line between the supply container and unit’s supply

isolation valve. A slight downward slope from the supply container to

the valve connection is required to prime the pump and maintain

positive head on the pump inlet. Always use a backup wrench when

making piping connections to avoid damage to the unit’s piping.

4. Open the shut off valve on the supply container and supply isolation

valve on the CS-1.

5. Open the pump suction isolation valve and allow liquid to enter the

reservoir tank. If there is enough liquid in the supply container, the

tank may be filled completely using this method. The tank is full when

the liquid level rises to the top of the straight section of the tank.

15.1.2 Pump Assist Fill:

6. If there is not sufficient liquid in the supply container to fill the tank or

the tank fills too slowly, the pump on the CS-1 may be manually

operated to speed up this process. Follow steps 1 to 4 above and 7 to

11 below to fill the storage tank using the pump.

7. Close the pump suction isolation valve and open the tank fill isolation

valve.

8. With the CS-1’s switch in the “OFF” position, turn on power supply to

the unit.

9. Position switches “A” and “B” in the center/off position. Switch the

“OFF-ON” switch to “ON” and the “Man-O-AUTO” switch on the unit

control panel to “Man”. Liquid will begin to fill the storage tank at the

fill connection.

10. Be careful to observe the liquid level to prevent over filling. When the

liquid level reaches the top of the straight section of tank, switch the

unit’s “Man-O-AUTO” switch to off.

11. Close the supply isolation and tank fill isolation valves. Open the

pump suction valve.
