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.
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 sec-
tion of the tank.

2. Pump Assist Fill:

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 2 to 5 below to fill the storage tank using the pump. 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.
1. Close the tank discharge isolation valve and open the tank fill isolation valve.
2. With the CS-1 "OFF-ON" switch in the "OFF" position, turn on power supply to the
unit.
3. Position switches "A" and "B" in the center/off position. Switch the "Man-O-AUTO"
switch on the unit control panel to "Man" and the "OFF-ON" switch to "ON". Liquid will
begin to fill the storage tank at the fill connection.
4. Be careful to observe the liquid level to prevent overfilling. When the liquid level
reaches the top of the straight section of tank, switch the unit's "Man-O-AUTO" switch
to "O".
5. Close the liquid supply isolation and tank fill isolation valves. Open the tank discharge
isolation valve.
F. Filling Systems
A suitable portable pump can be utilized to fill the system. (The CS-1 pump can be used for
filling the system initially at 15 GPM (56 l/min) to 100 ft head pressure or system static pres-
sure. However, it is a less efficient pump for filling the system because of the duration of time
required to do so. To fill the system, the system solenoid on the CS-1 is connected to the liquid
supply isolation valve of the Easy Riser
must be installed and set. The system to be filled is selected using two toggle switches on the
CS-1 control enclosure. Antifreeze from the supply is pumped to the system piping. Pump op-
eration is manually controlled during the fill process. The CS-1 pump is to be utilized to bring
the solution to maintenance pressure, and is designed to maintain system pressure once the
system is initially filled. Appropriate vent/bleed valves must be installed on each system's pip-
ing at all local high points to allow air to escape while liquid fills the system.
NOTE: Never leave the unit unattended when filling the system. Running the pump dry,
without liquid, will damage pump seals and possibly damage the pump impeller.
