TITAN SCR3 (01) PDF Document

The Mode (white) button’s functionality is to switch between 3 or 4 modes (depending on model) that show the performance of the water heater.

This is the default mode and shows the voltage being consumed and the percentage it represents from the total voltage. When the voltage is at 100% the water heater is working at full capacity. As that number starts to decrease the energy savings increases. Voltage is displayed in Volts (V).

The current mode shows the current being used and the percentage it represents from total current. Current is being displayed in Amps (A).

The power mode shows the amount of energy being consumed. It is the result of the voltage times the current being utilized. Power is being displayed in Kilowatts (KW).

This button is used to increase the temperature of the water. Please note that the water has to be running through the unit in order to adjust the temperature.

This button is used to decrease the temperature of the water. Please note that the water has to be running through the unit in order to adjust the temperature.

Please note that safety and energy conservation are factors to be considered when selecting the water temperature setting of the water heater’s thermostat. The lower the setting the greater the savings in energy and operating costs.

Households with children, disabled, or elderly persons may require a 120° F or lower thermostat setting to prevent contact with “HOT” water.

These units are designed to be installed using copper pipes with 1/2″ or 3/4″ depending on the model number that is being installed.

Always flush all the water lines before connecting the unit to the copper pipes.

After the unit is installed, open each hot water faucet slowly to allow the air to vent from the water heater and piping.

Do not use teflon tape or plumbing paste on compression fittings.

For ease of service, install a shut-off valve in both the inlet and the outlet of the unit.

Secure the unit to the wall utilizing only the brackets and compression fittings provided by Niagara Industries.

All plumbing work must comply with State and Local plumbing codes.

When using any type of plastic pipe like Pex or CPVC you MUST install 36″ of cooper pipe to both the inlet and outlet of the unit. DO NOT connect any plastic pipe directly to the unit. Also when using plastic pipes you MUST install a pressure relief valve on the inlet.

Test the installation for leaks before connecting to the electrical supply.

Check with a professional electrician for required breaker and wire gauge.

Use only the compression fitting ring and nut provided with each unit as shown above. Compression fittings are designed exclusively for these units, do not use a different type of threaded coupling.

Before beginning any work on the electric installation, be sure that the main breaker panel switch is “OFF” to avoid any danger of electric shock.

All mounting and plumbing must be completed before proceeding with electrical hook-up.

All electrical work must comply with national and applicable state and local electrical codes.

As with any electric appliance, failure to electrically ground unit may result in serious injury.

The breaker should be of same size than the energy consumption of the model being installed.

Make sure that all the connections are tight. DO NOT FORGET to install the ground wire to the main breaker panel.

Before you energize the unit, allow water to circulate during approximately 20 seconds to make sure the unit doesn’t work dry, which may damage the heating elements.

Do not turn on the power with the shutoff valves closed.

Do not attempt to repair or replace any part of the tankless water heater; a licensed qualified technician should be contacted to diagnose any problem.

The Titan tankless water heater must be installed in accordance with these instructions and local codes. In the absence of local codes, use the newer edition of the National Electric Code.

Locate the water heater in a clean dry area as near as practical to the area of greatest heated demand. DO NOT install the water heater in outdoor, unprotected areas.

Also, the water heater must be installed in a visual area with easy access to the water shutoff valves and to the power disconnect box as required by Electrical and Plumbing codes.

Do not turn on the power with the shutoff valves in an off position.

A minimum of 12″ clearance must exist from the top of the unit to ceiling and from bottom to floor.

TAMPERING WITH THE UNITS ELECTRONIC MODE, BREAKING THE SEAL OR REMOVING CONNECTION PARTS WILL VOID YOUR WARRANTY.

AS ALL ELECTRONIC APPLIANCE THIS UNIT MUST BE PROTECTED FROM RAIN AND WEATHER CONDITIONS.

WARNING: DISCONNECT FROM SUPPLY BEFORE SERVICING.

Before turning on the electricity let the water run for 20 seconds through the unit.

Note that excessive heat from soldering on copper pipes near the heater may cause internal damage.

If you have problems understanding the instructions in this manual STOP and get help from a qualified professional or contact customer support.

The PDF shows the following wire gauges based on the model for the TITAN SCR3 series (Column labeled SCR3):

The PDF provides the following electrical specifications for the TITAN SCR3 models:

The PDF shows the following maximum flow rates for the TITAN SCR3 models:

For the TITAN SCR3 model N-64, the temperature rise at 2.0 gpm flow rate is 26 deg.

The required voltage for the TITAN SCR3 model N-160 is 240.

The required breaker size for the TITAN SCR3 model N-180 is 2×40.

For the TITAN SCR3 model N-270, the temperature rise at 1.5 gpm flow rate is 118 deg.

Make sure to only use the brackets and screws that are provided in the mounting kit. The use of longer screws may damage the unit and void your warranty.

The installation diagram for the TITAN SCR3 SERIES indicates operation at 240 VAC 60Hz/50Hz.

The installation diagram for the TITAN SCR3 SERIES shows a 1/2 Inlet Cold Water and a 1/2 Outlet Hot Water connection.

For cpvc, pex or any plastic pipe you MUST use at least 36″ of Copper Pipe before and after the unit and install a pressure relief Valve for the TITAN SCR3.
