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:
