IMPORTANT SAFETY INSTRUCTIONS
Warning
When using electrical appliances, basic safety precautions to reduce the risk of fire, electric shock or injury
to persons should be followed, including:
1. READ ALL INSTRUCTIONS BEFORE USING THIS WATER HEATER.
2.This water heater must be grounded. Connect only to properly grounded outlet. Use
only the 3 prong plug that comes with the water heater. Do not use an adapter to
bypass the ground connection.
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. Contact a
service facility for examination, repair or adjustment.
9.Failure to service the anode rod at least once a year could cause the tank to fail and leak.

General Remarks
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 to about 60°C/140°F. To reduce the risk of
scald injury, keep the thermostat at the
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 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 open faucet at this time.

Installation Instructions
The P 10S and P 15S water heaters can be installed under the sink.
Wall Fasten the supplied mounting bracket to the wall. Use screws that are suitable for the wall
Mounting material and the weight of the heater.
Hang the water heater on the bracket. Tug downwards on the heater to ensure that both
"fingers" of the bracket are seated in the mounting slots.

Pipe Connect the cold water inlet pipe to the inlet nipple (marked with a blue ring - #1, Fig. 4).
Connections IMPORTANT: You must use dielectric fittings if inlet piping/fittings are copper or brass.
Failure to provide dielectric insulation may result in premature tank or nipple failure and will
void warranty. Dielectric nipples are recommended over unions and are available from a
supply house or CEC.
Caution To reduce the risk of excessive pressures and temperatures in this water heater, install
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, ANSI Z21.22. This valve must be marked with a
maximum set pressure not to exceed the marked maximum working pressure of the water
heater. Install the valve into the opening provided and marked for this purpose in the water
heater, and orient it or provide 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. The discharge opening must not be blocked or reduced in size under any
circumstances.
Closed Periodic discharge of the temperature and pressure relief valve or failure of the element
system gasket may be due to thermal expansion in a closed water supply system. The water utility
thermal supply meter may contain a check valve, backflow preventer or water pressure reducing
expansion 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.
