13.Lift the heat exchanger assembly out of the heater. Reinstall heat exchanger 180 degrees (inlet/outlet header left) from it's original posi- tion.

14.After replacing the heat exchanger into the heater, the end baffles must be replaced. Each one is held in place by two screws which mount to the top of the combustion chamber wall. Reinstall the baffles on the front and rear of the heat exchanger before continuing with the "Reversible Water Connections" procedure.

15.Remove pressure switch retainer (plastic cable clamp) from the inner panel (allow pressure switch to float).

16.On U.S. models reroute pressure switch tube and thermostat bulb assembly through hole in left side of vestibule cover in reverse order. Canadian models have no cover on the left side of the vestibule. Relocate the pressure switch tube and temperature sensor through the open side of the vestibule.

17.Reinstall the temperature sensing bulb in the header, and fasten it with the retainer bracket and screw.

18.Reinstall the compression fitting at end of pres- sure switch tube into inlet/outlet header and tighten the fitting.

19.Route the white wiring from the high limit switches beside the heat exchanger and down to the original location following the pressure switch tubing. Secure white wires to the pressure switch tube with plastic wire ties.

20.Connect the white wire labeled PS to the pressure switch and the other white wire to its original location on the Fireman's switch.

21.Reinstall the drain plugs and tighten securely. Replace jacket/plug grommets.

22.Install the flue collector assembly. Be sure the front and rear panels of the flue collector are installed into the grooves on the front and rear combustion chamber heat shield panels. Be sure the sheet metal panels are not pinching any wires.

23.Attach the flue collector hold down clamps to the clips located under the two center header bolts.

24.Replace the gap closures and tighten the screws securely.

25.Double-check to make sure the wiring is not pinched against sharp edges, or resting on the flue collector assembly.

26.Reinstall rainshield assembly.

27.Replace the top assembly. Make sure the tabs are outside the heater jacket. Fasten the top assembly with the hex-head screws.

28.Install plastic tie wraps on wiring in the vestibule (controls compartment).

29.Install heater door.

30.Reinstall the vent cap or drafthood, if one was removed.

2G-3. Check Valve Installation

Install a check valve if there is any chance of back- siphoning when the pump stops. Do not install any other valve in the piping between the heater outlet and the pool, unless it is being used as a diverter valve.

2G-4. Chlorinators, Ozone Generators,

and Sanitizing Chemicals

The Waterpik Laars Lite 2 heater is manufac- tured with materials that are not compatible with high concentrations of ozone, chlorine, bromine, or other sanitizing chemicals. Heater damage caused by exces- sive chemicals or improper ozonization is not covered by the Waterpik Laars warranty. Be sure to adhere to the following:

•When ozone is injected upstream of the heater, install an offgas mixing chamber, or an ozone bypass system between the heater and the ozone injector to prevent ozone and air from entering the heater.
