1. READ ALL INSTRUCTIONS BEFORE USING THIS WATER HEATER.

2. This water heater must be grounded. Connect only to a properly grounded outlet.

3. Install or locate this water heater only in accordance with the provided installation instructions.

4. Use this water heater only for its intended use as described in this manual.

5. Do not use an extension cord set with this water heater. If no receptacle is available adjacent to the water heater, contact a qualified electrician to have one properly installed.

6. As with any appliance, close supervision is necessary when used by children.

7. Do not operate this water heater if it has a damaged cord or plug, if it is not working properly, or if it has been damaged or dropped.

8. This water heater should be serviced only by qualified service personnel.

9. Do not use surge protectors or multi-outlet adaptors with this water heater.

IMPORTANT: Never plug in the power cord until the tank is completely full and water is flowing out of the hot water faucet.

The CAMPLUX ME40 is designed to supply hot water for handwashing in residential, commercial, or industrial environments. It is a slow recovery, small reservoir heater, not intended for showers or filling tubs. It is designed to be mounted on the wall and operate at a maximum water pressure of 150 PSI. If your water pressure is greater than 80 PSI, you must install a pressure-reducing valve.

CAUTION: The thermostat has been factory-set 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 for 125°F (52°C) will illuminate when the water is heating. If you choose a higher temperature, be aware of the increased risk of scalding. Thermostatic Mixing Valves at each point-of-use are important to help avoid scalding.

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 before using any electrical appliance connected to the hot water system. 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, adhering to all state and local codes. Choose a location that allows for easy access for maintenance, ideally at least 8″ to 9″ from the ceiling or any adjacent walls.

Wall mounting:

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 (ME40=57 lbs). Hang the water heater on the bracket and pull downwards on it to ensure both “fingers” of the bracket are seated in the mounting slots. Confirm your water piping orientation (hot and cold) before wall mounting. Only install in a vertical position. The heater can also sit on the floor in a tray with a drain, but again, only 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 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 open during operation. To protect the heater from heat damage during soldering, solder a piece of tubing to a threaded union fitting before screwing it to the tank. Do not apply heat directly to inlet or outlet connections.

To reduce the risk of excessive pressures and temperatures, you must install a combination temperature and pressure relief valve (T/P valve) certified by a nationally recognized testing laboratory. This valve must have 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 provided opening on the heater. Orient it or provide tubing so that any discharge exits within 6 inches above, or at any distance below, the structural floor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size.

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 can be due to thermal expansion in a closed water supply system (a system with a check valve, backflow preventer, or pressure reducing valve). During heating, water expands and increases pressure, causing the T/P valve to discharge.

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 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. Make sure the discharge of this valve is directed to an open drain and protected from freezing. Never plug the outlet of the relief valve.

CAUTION: Before plugging in the power cord, be sure the system is completely charged with water and all air is removed. 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.

To be certain that all of the air is out of the water heater, open the hot water faucet on your fixtures until constant water flows from them. 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 water heater is fitted with a power cord that is intended to plug into a grounded 120V/AC receptacle. Adhere to all pertinent state and local codes. Install the correct size circuit breaker into the master panel. The 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 either damaged or not long enough, do not use an extension cord. Have a licensed electrician replace the power cord.

You are now ready to use your water heater. Run the hot water at a nearby sink and evaluate the hot water temperature. Make any temperature adjustment using the instructions below:

Setting the thermostat:

The water heater is equipped with an adjustable thermostat that will automatically control water temperature once set. 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. The temperature adjusting knob will increase the temperature by turning the knob clockwise and decrease the water temperature by turning the knob counter-clockwise. When not being used for a lengthy period of time, 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 can either unplug and drain the water heater or turn the thermostat knob to the snowflake position to guard against freezing. This position will keep the internal water temperature above the freezing point.

WARNING: Before servicing or cleaning the water heater, 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 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.

1. Unplug the water heater power cord and drain the unit (see draining instructions).

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.

Scale deposits can affect the heating capability of the element. Heavy scale can even cause the element to burn out.

1. Remove the heating element (see instructions for removing the heating element).

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, using a non-metallic brush similar to a toothbrush, brush the residue from the element. Avoid damaging the surface of the element.

4. Reinstall the element and gasket.

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

1. Unplug and drain the water heater.

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

3. Install the new element with a 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.

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. 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. This occurs when water temperatures exceed 140°F (60°C). Power is automatically turned off to the heating element. It may also activate due to a power outage or electrical storm.

Note: Do not attempt to reset the high limit switch without first allowing the water 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.

CAUTION: Call a technician if the high limit needs to be reset frequently.

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

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

3. If the indicator light is illuminated, but the 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 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.

Under Instructions for Use, see “Setting the thermostat”.

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

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

3. Remove the cover and inspect the heating element gasket.
