Follow the steps below:
Turn off and isolate the electrical supply to the unit.
Close the liquid supply valve and Tank Fill isolation valves.
If not already connected to fill the storage tank, connect the antifreeze supply container
to the liquid supply 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 liquid supply valve. A slight downward slope
from the supply container to the unit’s valve connection is required to prime the pump and
maintain positive head on pump inlet. Always use a backup wrench when making piping
connections to avoid damage to the unit’s piping.
Open the shut-off valve on the supply container and liquid supply valve on the CS-1.
Open high-point vent/bleed valves on the system.
Select system to be filled using switches “A” and “B”. Use Table 14 or the table on the
CS-1 Panel to determine switch “A” and “B” position.
With the CS-1’s “OFF-ON” switch in the “OFF” position, turn on the power supply to the
unit.
Switch the “Man-O-AUTO” switch on the unit control panel to “Man”. Turn the “Off-On”
switch to “ON”. Liquid will begin to fill the selected system.
As the system fills, monitor the system vent/bleed valves. Close each valve when liquid
leaks from it.
When the liquid leaks from the uppermost vent/bleed valve, close the vent valve. The
system pressure switch will close that system’s solenoid valve when set pressure is
established. The pump pressure switch will turn the pump off when set pressure is es-
tablished.
