How to assemble the Philips Avent Manual Breast Pump

1. Insert the white valve into the pump body from underneath. Push the valve in as far as possible (Figure 1).
2. Screw the pump body clockwise onto the bottle until it is securely fixed (Figure 2).
3. Insert the stem in the silicone diaphragm. Make sure the stem is pushed through until the end (Figure 3).
4. Insert the silicone diaphragm into the pump body from above. Make sure it fits securely around the rim by pressing down with your fingers to ensure a perfect seal (Figure 4).
5. Attach the handle onto the diaphragm with stem by hooking the hole in the handle over the end of the stem. Push down the handle onto the pump body until it clicks into place (Figure 5).
6. Place the cushion into the pump body and make sure that the rim covers the pump body. Push in the inner part of the cushion into the funnel against the line indicated with an arrow and make sure the edges of the cushion are properly sealed around the pump body (Figure 6).
