IMPORTANT: Avoid installing tubes of different inside diameters in the pump chan-
nels controlling the impactor wash flow and the liquid sample outlet flow. Tubing with
the same inside diameter, material and age should be installed in the two channels
controlling the impactor washflow and liquid sample outlet flow to ensure the flow
rates are the same.

Note that even though flow rates higher than 1.5 to 2 ml/min are shown in table 1, the
steam heater flow rate must be 1.5 ml/min under normal operating conditions and the
impactor washflow and liquid sample outlet flows must not exceed 2 ml/min under nor-
mal operating conditions. Once the peristaltic pump speed is set to deliver 1.5 ml/min to
the steam heater, different impactor washflow and liquid sample outlet flow rates are
set by installing tubing with different inside diameters - NOT BY CHANGING THE PUMP
SPEED.
Temperature Controllers
The heater temperature controller controls the power delivered to the heater and the
time that the heater is on. The tip temperature is controlled by the steam heater temper-
ature and is only displayed by the temperature controller labelled 'Steam Tip'. A photo
of the controllers mounted in the PILS is shown in figure 2. The 'Steam Tip' temper-
ature controller does not control anything, it is only used to display the tip tempera-
ture. The tip temperature should be kept within the range 97.5-100 C. The user must
manually adjust the temperature setpoint of the heater temperature controller (labelled
