Combo Gas/Electric Electric Operation
1. For gas operation refer to Pilot, Pilot Relight or Electronic Ignition operation.
2. For electrical operation, use the switch inside the motorhome in the utility panel.
3. Completely fill tank with water.
4. Turn switch (Fig. 5-8) located in the motorhome to the "ON" position.
NOTE: Turning the power on in the heater with little or no water covering the heating
element may burn out the element and void the warranty.
5. Check for proper operation. Water temperature should be approximately 140°F (60°C).
6. If the manual reset high temperature limit switch should operate, reset the switch (Fig. 5-9)
by depressing the button. Use a pencil or other nonmetallic object. If still experiencing
problems contact an authorized Atwood Service Center or Atwood Service Department.
Read MAINTENANCE AND CARE INSTRUCTIONS.
When cold water is heated in the tank, the pressure will rise. For this reason, a relief valve (Fig. 5-10)
is required for safety in all water heaters, rated at 125° (52° C). It is normal for this valve to release a
small quantity of water during the heating cycle. Opening a faucet on the hot side will release
pressure reducing relief valve dripping.
