SAFETY

DANGER!
WATER TEMPERATURE SAFETY SETTING

Safety and energy conservation are factors to be considered when selecting the water temperature setting of water heater’s thermostat. Water temperatures above the 125°F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below. This label is also located on the water heater near the thermostat access panel.

Water temperature over 125 °F can cause severe burns instantly or death from scalds.
Children, disabled and elderly are at highest risk of being scalded.
See instruction manual before setting temperature at water heater.
Feel water before bathing or showering.
Temperature limiting valves are available, see manual.

Notice: To protect against injury, you should install a mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch supply lines. Such valves are available from your local plumbing supplier.

SELECTING AN INSTALL LOCATION

This product is designed to be installed indoors only. You may install your unit in an outdoor location so long as it is mounted in a suitable enclosure that protects it from rain, splashed water, direct sunlight, debris, and insects.

DO NOT install this product in a location where it may be subjected to freezing temperatures. If the water inside your tankless water heater freezes, it can cause severe and permanent damage that is not covered under your warranty.

DO NOT locate the water heater in a location that is difficult to access.

Make sure that the water heater and hot water outlet pipe are out of reach of children, so they are unable to tamper with the temperature controls or injure themselves by touching the hot water outlet pipe. The outlet water pipe can get very hot.

This product does NOT require venting.

Avoid installing your tankless water heater in a location prone to excessive humidity, moisture, or dust, or in an area where it may be splashed with water or other liquids.

DO NOT install under water pipes or air conditioning lines that might leak or condense moisture that could then drip onto the heater.

DO NOT install above electrical boxes or junctions.

CAUTION: The water heater should not be located in an area where leakage will result in damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the water heater.

MOUNTING YOUR WATER HEATER

Your tankless water heater should be secured to the mounting surface with 4 screws (minimum 1-inch long) using the built-in mounting brackets on each side of the heater. Make sure that the mounting surface is solid and secure and ensure that the unit is level prior to securing the screws. For ease of installation and servicing, we recommend that this product be installed in an upright position with the inlet and outlet water connections at the bottom of the unit.

Required Clearances:

12kW – 7 inches top and bottom
18kW – 12 inches top only
27kW – 14 inches top only
CAUTION: Combustible materials should be kept at /east 24 inches away from your water heater and the hot water outlet pipe.

PLUMBING INSTALLATION

Please follow all plumbing instructions carefully. We recommend that this product be installed by a licensed and qualified plumber in accordance with all applicable national, state, provincial, and local plumbing codes.

INSTALLATION INSTRUCTIONS

STEP 1: Make sure the inlet filter screen is present in the inlet fitting and the inlet and outlet pipes are correctly aligned with the heater connections to minimize stress on the heater.

CAUTION : Do not over-tighten plastic fittings.

STEP 2: Connect the plumbing to your water heater. The rule of thumb for installing tapered threaded fittings is finger tight plus ½ to 1 turn with a wrench. Do not tighten more than 2 turns past finger tight. Use 1 ½ turns of Teflon tape going clockwise around the thread, leaving the first 2 threads un- covered to avoid contaminating the water flow into the heater.

STEP 3: Fully open the inlet and outlet ball valves. Test with flow and without. Check the system for water leaks at all plumbing connections. If a leak is present at the NPT threads, slowly tighten the female NPT fitting up to 2 turns past finger tight. If still leaking, remove female NPT to check for damage or contamination. Replace Teflon tape before threading NPT back on.

1. Do not solder any pipes with unit connected to pipes – heat from soldering may damage the flow sensor. Doing so will void the warranty.
2. This automatic tankless water heater is equipped with both computer-controlled and electro- mechanical auto resetting thermostat switches for high-limited temperature protection. Since this product does not use a storage tank, the use of a temperature pressure relief valve (T&P) is not required for most installations. UL Standard 499 does NOT require that a pressure relief valve be used. However, a T&P valve may be required to meet installation codes in your area. If one is required, install the pressure relief valve in accordance with local codes and ensure that it operates correctly and that air is purged from the valve prior to installing the water heater. When connecting to Flex or High Temperature CPVC pipe, we recommend that a T&P valve be used for added safety. Please note: Installations in the Commonwealth of Massachusetts and State of Kentucky require a pressure relief valve. Please check your local installation codes for any special requirements.
3. The maximum operating water pressure is 150 PSI. If the water pressure is higher, a pressure reducing valve must be installed on the main incoming water supply line prior to installing the electric tankless water heater.
4. Flexible water heater hoses are recommended to be used with your water heater as part of the installation. When connecting the inlet water pipe to the unit, make sure to use a wrench to hold the unit’s connection, and another wrench to tighten, so that the flow sensor on the unit will not be loosened or damaged. Serious internal damage to the water heater can occur if the inlet or outlet connections are over tightened or if solder connections were made.
5. We recommend that a manual shut-off valve (ball valve) is installed on the inlet and outlet of the water heater so that there is a convenient shut-off point available in the event that future maintenance or servicing is required. It is extremely important to flush the lines to eliminate all plumbing paste or residue in the lines caused by any welding or soldering before connecting pipes to the water heater.

As with all electrical appliances, under no circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all power to the unit directly at the fuse or breaker box. Make sure to shut off all breakers. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.

All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code (NEC) in the USA, or the

Canadian Electrical Code (CEC) in Canada. Failure to do so could result in property damage and/or personal injury, and void your warranty. Note: The Canadian Electrical Code generally requires that all supply wires and corresponding circuit protection used for domestic hot water heating and hydronic heating applications be sized to a minimum of 125% of the maximum current rating of the heater (see model specifications below for details).

Before installing this product, ensure that the home has sufficient electrical power available to handle the maximum amperage load of the applicable model.

IMPORTANT NOTES:

Model 12 kW requires 1 set of wire and ground (see wiring diagram)
Model 18 kW requires 2 sets of wire and ground (see wiring diagram)
Model 27 kW require 3 sets of wire and ground (see wiring diagram)

Please see electrical specifications by model and wiring diagram on the next page for additional electrical information.

Each set of wires must be connected to its own individual double pole breaker.

INSTALLATION INSTRUCTIONS

STEP 1: Take each wire pair and connect them to one breaker (see wiring diagram). Make sure that each breaker is connected with one black wire and one red wire

STEP 2: Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers used, run the correct sets of wire from the home’s main breaker panel to the tankless water heater.

STEP 3: A separate ground conductor for each incoming circuit is required.

STEP 4: DOUBLE CHECK the electrical connections to make sure they are correct and that all wire connections are tight and secure. Also confirm that the correct breaker size and wire gauge has been used and confirm that the unit has been connected to a ground in accordance with applicable codes.

STEP 5: Confirm that all the air has been purged from the water lines prior to turning on power to the unit. Refer to STEP 2 in the plumbing installation section.

CAUTION: Ensure that you have made the correct connections. You must follow the wire connection as shown to ensure proper operation of the unit. If you mix up one set of wires with another, the unit will not operate correctly even though it turns on and otherwise appears to function properly

The water heater is now installed and ready to use! Follow the General Operating Instructions to complete the setup. We highly recommend that this is done with the homeowner present.

GENERAL OPERATING INSTRUCTIONS

Operating your new tankless water heater is similar to using any traditional water heating system. However, it is very important that you carefully read all of the setup procedures and operating instructions and tips to ensure the maximum performance and energy savings from your new water heater. We recommend that all members of the household read these General Operating Instructions.

How your new water heater works: Your tankless water heater does not store hot water like a traditional tank-type water heater. It contains high powered heating elements that are capable of heating water on-demand. As soon as you turn on a hot water faucet, a sophisticated flow sensor recognizes that you have turned on the water. This sensor measures flow rate while another sensor measures the incoming water temperature. This information is transmitted continually to the computer logic controls which decide how much power to send to the heating elements to heat the water to your desired temperature. Once the water faucet is turned off your water heater will turn off as well.

USER INTERFACE

CAUTION: Removing the cover to change the temperature set point exposes electrical shock and burn hazards, which can cause INJURY or DEATH. Adjustment should only be done by a licensed plumber or electrician.

DANGER : Hotter water increases the potential for Hot Water SCALDS.

CAUTION BEFORE SWITCHING THE ELECTRICAL BREAKER “ON”, VERIFY THE INLET AND OUTLET BALL VALVES ARE FULLY OPEN AND WATER IS FLOWING THROUGH THE HOT WATER FAUCET FOR A MINUTE OR TWO UNTIL THE FLOW IS CONTINUOUS AND FREE FROM AIR POCKETS. DO NOT SWITCH THE BREAKER “ON” IF THERE IS A POSSIBILITY THE WATER IN THE HEATER IS FROZEN.

COMMISSION HEATER

Upon power on, the software revision screen is displayed, then the power selection screen (12, 18, 27 kW).
The next screen represents the SAFE title, then “-1.5”G is displayed. This is a counter that represents the volume of water in gallons remaining to pass through the unit before the unit is considered commissioned.
At this point, water needs to be turned on.
After the counter reaches “0.0”, the temperature setpoint screen is displayed. At this point, the unit is commissioned and will heat water upon demand.
Temperature adjustable range: 60 °F – 140 °F

CHANGING SETPOINT TEMPERATURE

To INCREASE temperature, tap the “  + ” button repeatedly, or hold the “ + ” down
to INCREASE the temperature quickly.
To DECREASE temperature, tap the “ _ ” button repeatedly, or hold the “ _ ” down to DECREASE the temperature quickly.

Hold “ ” pressed for 3 seconds to access the Settings menu. To return to home screen press “ ” and hold for 3 seconds (will automatically return to home screen after 60 seconds of inactivity).

INITIAL STARTUP SCREEN FLOW

MAINTENANCE

To ensure maximum performance of your water heater and to reduce the risk of a water leak, we recommend the following maintenance:

Inspect the connections on the inlet and outlet of the water heater at least on an annual basis for any signs of damage or failure. Any signs of damage, cracks, leakage or weakness should be addressed. Take care not to over tighten the connections. Serious internal damage to your water heater can occur if you over tighten the water heater connections at the unit.

IMPORTANT NOTES:

As with all electrical appliances, under no circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all power to the unit directly at the fuse or breaker box.

SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.

When any maintenance is performed on the water heater or the home’s plumbing system that may introduce air into the plumbing pipes, it is important to turn the power off to the water heater and purge the air out of the lines before allowing the unit to power up. FAILURE TO DO SO COULD CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENT AND VOID YOUR WARRANTY.

If you have a water supply with a high level of mineralization (hard water), you should increase the frequency of your maintenance.

FLUSHING THE WATER HEATER

Flushing the heat exchanger is a complicated procedure that should only be performed by a qualified service technician.

NOTE:
Improper maintenance WILL VOID water heater warranty.

1. Disconnect electrical power to the water heater.

2. Close the shut off valves on both hot water outlet and cold water inlet lines (V1 and V2). See Figure 1.

3. Connect one hose (D1, Figure 1) to the valve (V3) and place the free end in a bucket.
   Connect one of the hoses (D3) to the circulation pump outlet and the cold water inlet line to valve V4. Connect the other hose (D2) to the circulation pump inlet and place the free end in the bucket.
   

4. Pour tankless water heater cleaning solution into the bucket. Ensure the cleaning solution is approved for potable water systems. Place the drain hose (D1) and hose D2 to the pump inlet in the cleaning solution.

5. Open service valves (V3 and V4) on the hot water outlet and cold water inlet lines.

6. Turn on the circulation pump. Operate the pump and allow the cleaning solution to circulate through the water heater for at least 1 hour at a rate of 4 gallons per minute.
   This will remove any possible harmful scale deposits.

7. Rinse the cleaning solution from the combination water heater as follows:
   a. Remove the free end of drain hose D1 from the bucket.
   b. Close service valve V4 and open shutoff valve V2.
   c. Do not open shutoff valve V1.
   d. Allow water to flow through the water heater for 5 minutes.
   e. Close shutoff valve V2.

8. Disconnect all hoses.

9. Remove the cold water inlet filter from the water heater and clean out any residues.

10. Reinsert the filter and ensure the filter cap is securely tightened.

11. Open a hot water faucet. Run the water heater continuously for five minutes to ensure all cleaning solution is purged from the system. Check for leaks and ensure the water heater is operating properly.

12. Connect electrical power to the water heater.

The following table represents some of the most common technical support questions.

PROBLEM

| POSSIBLE CAUSE|

SOLUTIONS

---|---|---
Water heater is not heating at all (water is flowing but the unit is not heating – the outgoing water temperature is the same as the cold water supply) – the digital display does NOT light up.| No power or incorrect wiring.| Make sure the breakers at main electrical panel are ON. You may have a faulty breaker or unit may be wired incorrectly
Flow rate is too low / water pressure is too low.| Your water heater has an activation flow rate of approximately 0.3 GPM. If your water flow rate is less than this level, your unit will not activate. Increase the flow rate.
Water heater is not heating at all (water is flowing but the unit is not heating – the outgoing water temperature is the same as the cold water supply) The digital display DOES light up| Internal part failure.| Please call us for technical assistance.
Water heater is heating, but the water temperature is not hot enough.| User temperature setting too low.| Turn up the temperature setting on the unit.
Flow rate is too high| Depending on your incoming water temperature and the power output of your model, your water flow rate may exceed the physical heating capacity of your water heater. Reduce the flow rate by installing an EcoSmart Flow Regulator. Use the chart in section 6 to find out which flow regulator works best for your particular model.
Crossed wires.| If it’s a new installation, have your electrician double check the wiring. Is possible that the wiring is incorrect.
Voltage less than 240 volts.| The heating elements on your water heater are design for 240 volts. When used with a lower voltage, they produce less heating power. You may need to upgrade to a larger model.
Mixing too much cold water.| You do not need to mix as much cold water with your tankless water heater compared to when you use a conventional water heater. You may also have an anti-scald feature on your faucet that is mixing cold water. These types of faucets can usually be adjusted to reduce the amount of cold water mixed.
The water temperature at the faucet is less than the temperature setting of my water heater| Voltage less than 208 volts.| The computer chips in your tankless water heater are programmed with the expectation that your incoming line voltage is 240 volts. If you have less than 240 volts, it may affect the reading on your water heater’s digital display and cause it to read slightly higher than the actual output temperature. To compensate for this, increase the setting on your water heater if you need / want hotter water.
Anti-Scald pressure/ balancing valve or tempering valve.| Your faucet may have an anti-scald feature or a tempering valve that automatically mixes cold water even when you turn your control lever or handle to full hot. These devices are usually adjustable so you can turn off the cold mix completely. You can compensate for this by increasing the setting on your water heater if you need/want hotter water.
Thermal loss due to long pipe run| As the hot water from the heater runs through the hot water delivery system to your faucet, some heat will be lost especially if it has long distance to travel or the pipes are cold. This is normal. You can compensate for this by increasing the setting on your water heater if you need/want hotter water.
