Pump Installation - TSI Instruments CA-CALC CA-6000 Series Replacement Instructions

Pump Installation

Find your replacement pump.
If you have an instrument with a draft sensor, disconnect the topmost blue draft tube from the draft port as
shown in Figure 7 below. This eases installation of your new pump.
Move the rubber sensor manifold up and out of the way as indicated in Figure 7, but do not pull hard on the
manifold tube.
If available, place a small bit of silicone lubricant on the surface of the pump ports. This eases pump port
insertion into the twin tubes.
Make sure the twin tube assembly, identified in Figures 6 and 7, is pushed down over the retaining tabs.
Insert the pump ports into the tube openings as shown in Figure 7. Push the pump in the direction shown
by the arrow, until the pump seats in the retaining well (identified in Figure 6).
Refer again to Figure 4. Plug the power connector into the power connection, noting the orientation of the
connector. The connector plugs in only one way, wires to the back.
Replace the draft tube shown in Figure 7 by pushing it over the draft port. Pull the pump wires down to the
side of the pump. When complete the assembly should appear as in Figure 3.
Replace the sensor or sensors you removed, and the sensor plug, if used. If one of your sensors is a CO
sensor, such as that shown in Figure 2, also replace the CO foam gasket, aligning the tab on the sensor
manifold with the notch in the gasket. Refer to Figure 8. Sensor replacement is described in your
instrument instruction manual.
