The thermostat on the CAMPLUX ME10 water heater has been set at the factory to 125°F (52°C) or lower to reduce the risk of scald injury. The recommended starting setpoint is identified on the dial. The red indicator light at the center of the display will illuminate when the water is heating. When the water in the tank is at the desired temperature, the red indicator will NOT be illuminated.

If you choose a higher temperature, be sure to read and follow the warnings outlined on the label located on the water heater near the top of the tank. The following table shows the approximate time it takes to produce a serious burn at various water temperatures.

Hydrogen gas builds up in a hot water system when it is not used for a long period (two weeks or more). Hydrogen gas is extremely flammable. If the hot water system has not been used for two weeks or more, open a hot water faucet for several minutes at the kitchen sink before using any electrical and most distant sink being served by this water heater. This will allow the flammable gas to vent safely. Do not smoke or have an open flame or other ignition source near the faucet while it is open.

The installation must be completed by a licensed professional. Choose a location that allows for easy access for maintenance, ideally at least 8″ to 9″ from the ceiling or any adjacent walls.

1. Fasten the supplied mounting bracket to the wall. Use screws that are suitable for the wall material and the weight of the water heater filled to capacity (ME10 = 24 lbs).

2. Hang the water heater on the bracket and pull downwards on it to ensure that both “fingers” of the bracket are seated in the mounting slots.

3. Confirm your water piping orientation (hot and cold) before wall mounting.

4. Only install the CAMPLUX ME10 in a vertical position. The heater can also sit on the floor in a tray with a drain, but it must still be in a vertical position.

Connect the cold water inlet pipe to the inlet nipple (marked with a blue ring) and the hot water outlet pipe to the outlet nipple (marked with a red ring).

IMPORTANT:

• If water pipes are copper or bronze, use dielectric connections to prevent corrosion. Failure to do so may result in premature tank or nipple failure and may void your warranty.

• Ensure that the water heater is installed in a level position.

• Install a shut-off valve on the cold water side of the water heater for servicing. The valve should be in the open position when the water heater is in operation.

• To protect the water heater from heat damage due to soldering, solder a piece of tubing to a threaded union fitting before screwing the union to the tank. Do not apply heat directly to inlet or outlet connections.

To reduce the risk of excessive pressures and temperatures, install the Temperature and Pressure protective equipment required by local codes. This must be no less than a combination temperature and pressure relief valve (T/P valve) certified by a nationally recognized testing laboratory. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater (150 PSI). Install the T/P valve into the opening provided and marked for this purpose on the water heater.

The T/P valve discharge pipe must adhere to the following rules:

1. Must not be smaller in diameter than the outlet diameter of the valve, or have any reducing couplings.

2. Must not be plugged or blocked.

3. Must be made of suitable material for hot water.

4. Must not be over 15″ in length.

5. Must not have more than two elbows.

6. Must terminate at an adequate drain.

7. Must not have a shut-off valve between the relief valve and tank or between the relief valve and termination of discharge.

Periodic discharge of the T/P relief valve or failure of the element gasket may be due to thermal expansion in a closed water supply system. A closed system can be created by a check valve, backflow preventer, or water pressure reducing valve in the utility supply meter. During the heating cycle, the heated water expands, causing pressure inside the water heater to increase, which can lead to the T/P valve discharging hot water.

To prevent this, there are two recommendations:

1. Install a diaphragm-type domestic hot water expansion tank (suitable for potable water) on the cold water supply line. The expansion tank should have a minimum capacity of 1.5 U.S. Gallons for every 50 gallons of stored water.

2. Install a 125 PSI pressure relief valve in the cold water supply line. Ensure the discharge of this valve is directed to an open drain and protected from freezing. Never plug the outlet of the relief valve.

Before plugging in the power cord, you must be sure the system is completely charged with water and all air is removed. Otherwise, any air remaining in the tank will cause the water heater element to self-destruct.

1. Open the hot water faucet.

2. Open the cold water supply valve.

3. When continuous water flows out of the faucet, the tank is filled.

4. Close the hot water faucet.

5. Check the entire system for leaks.

First, be certain that all air is out of the water heater by opening a hot water faucet until constant water flows from it. If air remains in the tank, the element will be damaged when the electric cord is plugged in.

Grounding Instruction:

Connect the water heater to a grounded outlet. The CAMPLUX ME10 is fitted with a power cord intended to plug into a grounded 120V/AC receptacle. Adhere to all pertinent state and local codes and install the correct size circuit breaker into the master panel.

The water heater is equipped with an overheat limiting device (temperature high limit) with a manual reset. This device is factory installed to interrupt the power supply in the event of a thermostat failure.

This water heater is designed for only 120V electrical service! Do not connect to any other voltage. Failure to use proper voltage may result in personal injury and/or property damage. If the supplied electrical power cord is damaged or not long enough, do not use an extension cord. Have a licensed electrician replace the power cord.

Once the heater is filled and connected, you are ready to use it. Run hot water at a nearby sink to evaluate the temperature.

Setting the thermostat:

The CAMPLUX ME10 is equipped with an adjustable thermostat that automatically controls water temperature. The red indicator lamp remains illuminated while the water is being heated. If the water in the tank is at the desired temperature, the lamp will not be illuminated.

• Turn the temperature adjusting knob clockwise to increase the temperature.

• Turn the knob counter-clockwise to decrease the water temperature.

When not being used for a lengthy period, you can conserve energy by reducing the water temperature setting.

When the water heater is not being used for an extended period and there is a risk of freezing, you have two options:

1. Unplug and drain the water heater completely.

2. Turn the thermostat knob to the snowflake position to guard against freezing. This position will keep the internal water temperature above the freezing point.

Before servicing or draining, always disconnect the power cord from the electrical outlet.

1. Unplug the water heater.

2. Open a hot water faucet to let hot water run out. Allow water to flow until it is no longer hot.

3. Turn off the cold water supply to the water heater.

4. Close the hot water faucet.

5. Disconnect the water heater from both the hot and cold water connections.

6. If possible, siphon out any remaining water.

7. Carefully detach the water heater from the wall.

8. Tilt the water heater to drain the remaining water out of the heater.

Scale deposits can affect the heating capability of the element. Heavy scale can even cause the element to burn out. The element can be descaled chemically or manually.

Removing the heating element:

1. Unplug the water heater power cord and drain the unit.

2. Remove the cover.

3. Remove all the line wires from the heating element.

4. Unscrew the heating element retaining nuts.

5. Remove the element.

Descaling the heating element:

1. Remove the heating element as described above.

2. To descale chemically: Soak the heating element in white vinegar or another descaling solution and then rinse well with fresh water.

3. To descale manually: Let the element dry and then use a non-metallic brush (similar to a toothbrush) to brush the residue from the element. Avoid damaging the surface of the element.

After descaling, reinstall the element and gasket, then refill the tank with water before plugging in the power cord.

1. Unplug and drain the water heater.

2. Remove the old heating element, noting the original positions of all connections.

3. Install the new element with its gasket, making sure the new element and gasket are positioned correctly.

4. Tighten the retaining nuts and make the wire connections to their original locations.

5. Refill the tank with water before plugging in the power cord.

1. Unplug the water heater power cord from the electrical outlet.

2. Drain and remove the water heater.

3. Remove the six screws retaining the bottom panel of the water heater and remove the panel.

4. Remove the thermostat knob and unscrew the two retaining screws. It may be necessary to pry the knob off of the thermostat spindle. Now remove the front panel.

5. Disconnect the push-pull wire connectors on the thermostat, noting which connector goes to which terminal. The terminals are marked.

6. Remove the thermostat probe from the well.

7. Install the new thermostat, attach wires, and tighten screws.

The high limit safety shut-off switch will occasionally shut the water heater down if water temperatures exceed 140°F (60°C). This can also be activated by a power outage or electrical storm. Do not attempt to reset the switch without first allowing the high temperature water inside the heater to cool down.

WARNING: Do not tamper with the reset button to override the overheating shut down.

1. Unplug the water heater power cord from the electrical outlet.

2. Drain and remove the water heater.

3. Remove the six screws retaining the bottom panel of the water heater and remove the panel. Locate the high limit reset button.

4. Depress the small red button in the center of the junction box, replace the bottom panel, and place the water heater back into service.

Note: A lower temperature setting saves energy and reduces the risk of scalding. Call a technician if the high limit switch needs to be reset frequently.

1. Make sure the power supply is on and working.

2. If the indicator light does not come on, check that the high limit reset button is pushed in; follow the steps from the “Resetting the high limit switch” section.

3. If the indicator light is illuminated, but water temperature does not get hot at the sink, test for a plumbing crossover. To do this, shut off the cold water supply to the water heater and open the hot water tap. There should be no water flowing. Any continuous flow indicates a crossover which will affect the temperature and will need to be corrected.

4. If there is no crossover, then replace the heating element.

1. If the light does not come on, but water gets hot, check for a faulty bulb.

2. Check the high limit reset button by following the steps in the “Resetting the high limit switch” section.

Turn the temperature knob counter-clockwise to a lower temperature setting. If the temperature does not lower within 60 minutes, then replace the thermostat.

Refer to the “Setting the thermostat” instructions under the Instructions for Use section to adjust the temperature to a higher setting.

1. Unplug the water heater power cord from the electrical outlet.

2. Check the water fittings and the T&P fitting in the top of the tank for leaks.

3. Remove the cover and inspect the heating element gasket for damage or improper seating.
