GENERAL INFORMATION

The Eccotemp Mini Tank water heaters can be used in most under the

counter, point of use applications. EM Models are designed to supply hot

water for all hand wash and kitchen sinks in a residential, commercial or

industrial environment.

EM Models can replace traditional central hot water heaters thereby

conserving water and reducing energy waste. EM Models can also be

plumbed in series with the central water heater and act as a booster.

The Eccotemp Mini tank water heaters are lightweight and compact and

manufactured for easy installation. EM Models can be mounted on the

wall with included hardware, or freestanding.

EM Models are designed to operate at 150 psi maximum water pressure.

Install a pressure reducing valve if your water pressure is greater than

150 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 thermostat has been pre-set at the factory between

105° F (41° C) and 113° F (45° C).

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 nearest and

most distant sink being served by this water heater before using any

electrical appliance connected to the hot water system (i.e. Dishwasher).

If hydrogen gas is present, there will probably be an unusual sound such

as air escaping through the faucet as the water begins to ﬂow. There

should be no smoking or open ﬂame near the faucet at this time.

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 three Eccotemp Mini tank models, a 2.5 gallon model, a 4

gallon model & a 6 gallon model. 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

EM-2.5 / EM-4.0 / EM-6.0

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 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 (EM-2.5 = 41 lbs, EM-4.0 = 57 lbs., and EM-6.0 = 76

lbs.) Hang the water heater on the bracket and pull downwards on the

water heater to insure that both “ﬁngers” of the bracket are seated in

the mounting slots.

Conﬁrm your water piping orientation (hot and cold pipes) before

wall mounting.

ONLY INSTALL IN VERTICAL POSITION.

Heater can sit on the ﬂoor. Conﬁrm water piping orientation before

ﬁnalizing on ﬂoor. ONLY INSTALL IN VERTICAL POSITION! EM Models

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 premature tank or nipple failure and may void your

warranty. Insure 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.

TEMPERATURE AND PRESSURE RELIEF VALVE:

CAUTION!: Install the Temperature/Pressure Relief Valve supplied with

the water heater!

Install a discharge pipe from the temperature/pressure relief valve

terminating at a sink or drain. DO NOT CAP OR PLUG THE END OF THE

DISCHARGE PIPE. THE DISCHARGE PIPE MUST BE UNOBSTRUCTED AND

FULL SIZED.

The T/P valve is certiﬁed by a nationally recognized test lab that

maintains periodic inspections of the listed equipment and meets the

requirements for relief valves and automatic shut off devices for hot

water supply systems ANSI 121.22-1979.

The T/P valve is marked with a maximum pressure, which does not

exceed the maximum working pressure of the water heater (150 PSI).

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 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.

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.
