Sets the pump speed to 4.
Sets speed to maximum of 999. Button must be kept depressed in order to maintain
maximum speed.
Note: If this button is depressed too long the pump will stop to prevent the motor burning out.
Normal run starts the pump and permits remote control of the pump standby speed as determined
by the Omnion software at the end of a run or batch. The pump runs at the displayed speed.
Normal speed is 35. Use the
If Omnion is set to Standby speed, the pump will run very slowly and the display will show rc 3.
The display rc 3 indicates remote control speed 3.
Manual running allows the pump to override the remote control of the standby speed.
This button toggles between manual speed control and manual stop.

Place all of the reagent lines into their corresponding containers or in deionized water. To
avoid reagents leaking on the system, run deionized water through all of the lines to
detect any leaks. If the manifold has a cadmium column, make sure it is bypassed. Water
and air will damage the cadmium column.
Note: Some methods require certain reagents to be pumped first. For example, the TKN method
has a buffer solution that has to be run first to avoid a white precipitate in the manifold tubing. Check
the QuikChem method for instructions.
