General Information

The Camplux mini-tank water heaters can be used in most under-the-counter, point-of-use applications.

Models ME10, ME25, ME40, and ME60 are designed to supply hot water for handwashing in a residential, commercial or industrial environment. The Camplux mini-tank water heaters are slow recovery, small reservoir, not intended for showers or filling tubs. The Camplux mini-tank water heaters are lightweight, compact, and manufactured for easy installation. The ME10, ME25, ME40, and ME60 are designed to be mounted on the wall.

The ME10, ME25, ME40 and ME60 are designed to operate at 150 PSI maximum water pressure. Install a pressure reducing valve if your water pressure is greater than 80 PSI.

CAUTION
The manufacturer cannot be responsible for the damage caused by improper installation or by failure to follow instructions in this manual. Comply with the Installation Instructions before connecting to electrical outlet.

CAUTION
The thermostats on this water heater have been set at the factory to 125°F (52°C) or lower to reduce the risk of scald injury;

Locate the front panel and temperature adjustment knob on the water heater. The recommended starting setpoint is identified on the dial as. The red indicator 125°F (52°C) 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 below. This label is also located on the water heater near the top of the tank. Thermostatic Mixing Valves located at each point- ofuse are particularly important to help avoid scalding.

CAUTION

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 fammable. 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.

WARNING

Installer should review the contents of this manual with the owner upon completion of the installation, and the manual should remain with the owner and  placed in a location close to the water heater.

Technical Description

There are 4 Camplux Mini Tank models with 1.3, 2.5, 4.0 and 6.0 gallon capacity. The pressure vessel (water tank) is welded, glass lined steel and is equipped with an anode rod. The water heater is equipped with a thermostat and a high limit temperature switch. A temperature pressure relief valve is supplied with the unit.

Installation Instructions

ME10 / ME25 / ME40 / ME60
The installation must be completed by a licensed professional. All state and local codes must be adhered to. The manufacturer will not be liable for any damages because of failure to comply with these installation instructions or because of improper installation performed by an unqualified installer. Choose a location that allows ease of access for maintenance or servicing, ideally installed at least 8” to 9” from the ceiling (inside top of cabinet) 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 (ME10=24 lbs, ME25=41 lbs, ME40=57 lbs, ME60=76 lbs). Hang the water heater on the bracket and pull downwards on the water heater to ensure that 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 vertical position. The heater can sit on the floor in a tray with a drain. Confirm water piping orientation before finalizing on the floor. Again, only install in vertical position! Models ME10, ME25, ME40, and ME60 can be installed under the sink.

Plumbing Connections

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 provide dielectric insulation may result in the 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. The valve is for servicing and the valve should be in the open position when the water heater is in operation. In order 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.

Temperatures & Pressure Relief Valve

CAUTION

To reduce the risk of excessive pressures and temperatures in this water heater, Install the Temperature and Pressure protective equipment required by local codes and no less than a combination temperature and pressure relief valve certified by nationally recognized testing laboratory that maintains periodic inspections of production of listed equipment or materials, as meeting the requirements for relief valves and Automatic Gas shutoff devices for Hot water supply systems ANSI 121.22. 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 an opening provided and marked for this purpose in the water heater,and Orient it or provide tubing so that any discharge from the valve exits only within 6 inches above, or at any distance below the structural foor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances.

T/p valve discharge pipe

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 relief valve and tank or relief valve and termination of discharge.

Figure – The T&P Relief Valve discharge pipe must be installed properly and piped to an adequate drain.

Closed system thermal expansion:

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. The water utility supply meter may contain a check valve, backflow preventer, or water pressure reducing valve which will create a closed water system. During the heating cycle of the water heater, the heated water expands causing pressure inside the water heater to increase. The t/p relief valve may discharge hot water under these conditions which results in a loss of energy and a build-up of lime on the relief valve seat.

To prevent this from happening, 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 must 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. Make sure the discharge Of this valve is directed to an open drain and protected from freezing. Contact your local water Utility or plumbing inspector for information on how to control this situation. Never plug the outlet of the relief valve.

Filling the Water Heater

CAUTION

Before plugging in the water heater power cord into an outlet, be sure that the system is completely charged with water and all air is removed. Before connecting the power, fill the tank and system with water and check for leaks. To be sure that all air is out of the water system, open the hot water faucets on your fixtures until constant water flows from them. 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 entire system for leaks.

Electrical Connections

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 Camplux mini-tank water heater was manufactured and wired in accordance with UL requirements. The water heater is equipped with an overheat limiting device with a manual reset. Also known as the temperature high limit, this device has been 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 either damaged or not long enough, do not use an extension cord. Have a licensed electrician replace the power cord.

Instructions for Use

Congratulations!

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 section below:

Setting the thermostat

The water heater is equipped with an adjustable thermostat that once set will automatically control 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.

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.

Setting the freeze protection

When the water heater is not being used for an extended period of time and there is a risk of freezing, 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. See the photo below.

Maintenance Instructions

Do not attempt to repair this water heater yourself. Call a service person (plumber or electrician) for service assistance. Always unplug the power supply cord when the water is turned off or when servicing or draining the water heater. Before calling for service, first confirm that the water heater is properly filled and that 120 VAC power has not been interrupted.
