GENERAL REMARKS
CAUTION: Prior to connecting the power supply, ensure tank is full of water and
system is purged of air.
CAUTION: The manufacturer cannot be responsible for the damages caused by
improper installation or by failure to follow instructions in this pamphlet. Comply with
the installation instructions before completing electric connection.
CAUTION: The thermostat has been pre-set at the factory between 10°C (50° F)
and 60° C (140° F).
CAUTION: Hydrogen gas can be produced in a hot water system served by this
heater that has not been used for a long period of time (generally 2 weeks or more).
Hydrogen gas is extremely flammable. To reduce the risk of injury under these
conditions, it is recommended that the hot water faucet be opened for several
minutes at the kitchen sink before using any electrical appliance connected to the
hot water system. If hydrogen gas is present, there will probably be an unusual
sound such as air escaping through the pipe as the water begins to flow. There
should be no smoking or open flame near the faucet at this time.
WARNING: installer should be 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.
INSTALLATION INSTRUCTION
The installation for electrical and plumbing work must be carried by qualified
personnel according to the installation instruction and compliance to the local
authority regulations. 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.
Wall-mounting
Fasten the supplied mounted bracket to the wall. Use screws that are suitable for the
wall materials and the weight of the heater, Hang the water heater on the bracket.
Pull downwards on the heater to ensure that both *fingers” of the bracket are seated
in the mounting slots.
Heater can sit on the floor. Confirm water piping orientation before finalizing on floor.
ONLY INSTALL IN VERTICAL POSITION! The water heater can be installed under
the sink.
09
Pipe 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).
TEMPERATURE AND PRESSURE RELIEF VALVE
CAUTION: To reduce the risk of excessive pressures and temperatures in this water
heater, install the supplied temperature and pressure protective equipment required
by local codes but not less than a combination temperature and pressure relief valve
certified by a nationally recognized testing laboratory that maintains periodic
inspection of production of listed equipment or materials, as meeting the
requirements for Relief Valves and Automatic Gas Shut-off Devices for Hot Water
Supply Systems, ANSIZ21.22. The supplied temperature and pressure relief valve
is marked with a maximum set pressure (150 psi) that does not exceed the marked
maximum working pressure of the water heater. The valve must be oriented,
provided with tubing, or otherwise installed so that the discharge can exit only within
6 inches above, or at any distance below, the structural floor and cannot contact any
live electrical part. The discharge opening must not be blocked or reduced in size
under any circumstances.
Install the T&P valve into the threaded opening at the top of the water heater and
orient the discharge tubing so that any discharge from the valve will exit within 6
inches above, or at any distance below ,the structural floor ,and cannot contact any
live electrical part.
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 materials 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 and tank or relief valve and
termination of discharge.
10
Closed System thermal expansion: Periodic discharge of the temperature and
pressure 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
water expands causing pressure inside the water heater to increase. The
temperature and pressure 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 expansion tank that is 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 the local water supplier or plumbing inspector for information on how to
control this situation. Do not plug the temperature and pressure relief valve.
ELECTRICAL CONNECTION
CAUTION: To be certain that all of the air is out of the water heater, otherwise ,the
element will be damaged when connected to power!!! Open the hot water faucet on
your fixtures until constant water flow from them.
Connect the water heater to a GROUND POWER SUPPLY
The water heater is fitted with an electrical connection that is intended to Connect to
a grounded 110-120V/AC supply. Adhere to all pertinent State and local codes.
Install the correct size circuit breaker into the master panel. The 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 resets.
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 110V-120V electrical service! Don't
connectto higher or lower voltage!!
Failure to use proper voltage may result in personal injure and/of property damage.
If the supplied electrical connection is either damaged or not long enough, do NOT
use the extension cord. Have a licensed electrician replace the power cord.
11
INSTRUCTIONS FOR USE
Starting and testing
Before connecting the power, fill the tank and system with water and check for leaks.
To be certain that all air is out of the water system, open the hot water faucets on your
fixtures until constant water flows from them otherwise damage to the element may
occur.
Tostartthe heating cycle:
A) first make sure tankis full. Otherwise the heating element may be damaged.
B) the red light will come on and remain on until that temperature has been reached,
at which point the light will go off, but will automatically come back on when the water
temperature drops below the setting chosen.
Temperature Setting
The water temperature of the hot water is adjusted by rotating the knob Turn the
knob clockwise to increase the temperature .Turn the knob anticlockwise to
decrease it. Below is an image of the knob.
Temperature adjusting Knob

MAINTENANCE
NOTE: Do not attempt to repair this water heater yourself. Call a service person for
assistance. Always turn off the power supply to the heater prior to servicing or
draining the heater.
WARNING: Before servicing or cleaning the water heater, turn off the POWER
switch and disconnect power.
NOTE: For most of these operations, the water will have to be drained from the
heater. In cases before draining first turn off the POWER switch and then disconnect
power.
Draining the water
1) If the heater has been installed with flexible hoses, shut off the power supply and
turn the heater upside down over a sink to drain the water out of it.
2) If the heater has been installed with rigid piping, siphon the water out through the
inlet side. Keep a hot water faucet open while siphoning the water out.
3) If the heater has been installed with flexible hoses, it can also be emptied by
Siphoning through the inlet side hose. Keep a hot water faucet open while
siphoning.
Removing the heating element
1) Turn off power supply and drain the heater.
2) Remove cover.
3) Unscrew the heating element retaining nuts.
4) Remove the element.
Descaling the heating element
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 either chemically
or manually:
A) Soak the element in white vinegar or other descaling solution once descaled
rinse well with fresh water, to which you should add some baking soda.
B) Once the element has dried up, use a soft brush (hon metallic to prevent
damaging the stainless steel sheath) on element. Brush the dried mineral off.
Reinstall the element with gasket and make the wire connections.
WARNING: make sure the tank has been refilled with water before restoring power.

REPLACEMENT OF PARTS
Changing the anode rod
The anode rod helps protect the tank against corrosion. Depending on the
water condition, the magnesium anode rod may need to be changed every year or
so. Galvanic and electrolytic corrosion can destroy a tank if the anode rod is “spent”
Rusty water is usually an indication of a “spent” anode rod. If rusty water is present,
examine anode rod immediately. Rapid degradation of the anode rod (less than
1year) may indicate the presence of galvanic corrosion due to “stray” direct current.
In this case, it may be necessary to add a “grounding strap” from the tank to the
copper plumbing.
1. Turn off the power supply and drain the heater
2. Remove heating element
3. Remove and replace the anode rod
4. Refill tank with water before restoring power.
Changing the heating element
1. Turn off power switch, turn off the power supply and drain the heater.
2. Remove the cover and remove the heating element (see section on Removing the
Heating Element).
3. Install new element with gasket, making sure the gasket and element are
positioned correctly. Tighten the retaining nuts and make the wire connections.
4. Refill tank with water before restoring power.
Changing The thermostat
1. Turn off power switch and turn off power supply.
2. Drain and remove the water heater.
3. Remove the bottom panel of the water heater.
4. Loosen the two brass screws and pull wires out.
5. Unscrew and remove the two screws holding the thermostat down.
6. Install new thermostat and re-attach wiring and screws.
Resetting High Limit Switch:
Occasionally, the high temperature limit shut off device may trigger and shut the
system down. This occurs when water temperature exceeds 190° F and shuts off
power to the heating element. The shut off device may also trigger from a power
outage or electrical storm.
14
1) Turn off the power switch and disconnect heater from the power. supply
2) Drain and remove the water heater
3) Remove the bottom panel of water heater
4) locate the high limit reset button.
5) Depress the small red button in the center of the junction box, reduce the bottom
panel and place the water heater back into service.
NOTE: Alower setting is more economical, and reduces the risk of scalding.
CAUTION: Call a technician if the high limit needs to be reset frequently.
TROUBLE-SHOOTING GUIDE
Water does not get hot
1. Make sure the power supply is on and working.
2. If light does not come on, check that the reset button is pushed in; follow steps
from previous section.
3. If the indicator light works properly but temperature does not get hot a tap, test for
a plumbing crossover; shut off cold supply to heater and open hot water tap. There
should be no water flowing. Any continued flow indicates a crossover which will
effect the temperature and will need to be corrected.
4. Replace heating element
Light noton
1. Ifthe light does not come on, but water gets hot, check for faulty bulb.
2. Check reset button; follow steps from previous section.
Odor in water
1. Smelly water could be due to an unusual reaction between local water and the
heater's anode rod. Check anode rod.
Water is too hot
1. Remove cover plate and turn the temperature selector dial counter
clockwise to lower temperature. If temperature never lowers then replace
thermostat.
Water not hot enough
