Install the Gas Ring

1. Install the gas ring by placing it around the heater element on the Heater/Cooler base as shown in Figure 1. Orient the clearance groove in the bottom of the gas ring over the barb cooling water fittings. The magnets will hold it in place.

2. Connect the gas inlet:
   • Using the small in-line mating fitting, connect the short (approximately 30 cm) black polyurethane tubing to the gas quick-disconnect coupling on the manifold (see Figure 2).

3. Connect the other end of this tubing to one of the barb fittings on the gas ring.
   • Run this tubing, along with the water tubing, through the clamps on the top on the gas flow meter as shown in Figure 3.

4. Supply the gas to the flow meter:
   • Run the long (approximately 275 cm) length of (supplied) black polyurethane tubing from your regulated gas supply to the bottom, rear fitting on the flow meter, shown in Figure 2 and connect it using the small in-line mating fitting.
