Setting up Valve
Set up consists of:
1. Pump to Valve Electrical Connections:
The cable fitted with a male 3 pin connector must be connected to the
female connector on the rear of the Model 33. The Model 33 should be
turned off when making/breaking this connection.
2. Valve tubing to syringe hook up:
The valve(s) are de-energized when the front mechanism (#1) is running in
the INFUSE direction. The syringe on the #1 mechanism when infusing
should therefore be connected to the lower tubing in the pinch valve (see fig-
ures on next page).
