Plumbing Requirements and Precautions

• Please follow all plumbing instructions carefully. This product must be installed in accordance with all national, state, provincial, and local plumbing codes. We recommend consulting with your municipality or a qualified plumber if you have questions relating to plumbing codes for your area prior to installing.

• The plumbing installation must be completed before the electrical installation.

• DO NOT solder any pipe with the unit connected to the pipe. The heat from soldering may cause damage to the flow sensor. Doing so will void the warranty.

• The plumbing installation requires piping that can withstand pressure up to 8 BAR.

• The water supply flow rate must be at least 0.5 Gallons per Minute (GPM) to ensure proper operation.

• Flexible braided, stainless steel water hoses are recommended to be Fig. 7 used with your water heater when installing your water heater.
  

• Do not over-tighten the water inlet and outlet connections to avoid severe internal damage to the water heater.

• All the water pipes within 3 feet (1 meter) of the inlet and outlet connections are recommended to be rated for high-temperature applications with 150°F (66°C) minimum.

• Before proceeding to the electrical installation, run water through the unit for several minutes to flush out any air bubbles from the water line.

Plumbing Installation

STEP 1: Thoroughly flush cold supply line of debris.

STEP 2: Connect the HOT WATER line to the water heater OUTLET. The water heater outlet can be seen on the left side of the heater when facing the unit. Connect the COLD-WATER line to the water heater marked COLD WATER INLET which is located on the right side when facing the unit.

• Pre-heated water can be connected to the cold water inlet, where this unit will act as a booster.

STEP 3: After tightening both fittings at the water heater, several hot water faucets should be opened to allow the flow of water through the water heater for at least 2 to 3 minutes. This process purges all the air from the water lines and MUST be performed before turning on the power at the unit.
FAILURE TO FOLLOW THIS STEP MIGHT CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENTS. (The power to the heater should be turned off and the air purged out of the lines before turning the power on anytime maintenance is performed on the water heater or the homes plumbing system, as air might have been introduced into the plumbing pipes.)

STEP 4: Carefully inspect all connections, units, and the pressure relief device for leaks after the plumbing installation is completed. If there are no leaks present, you can proceed to the electrical
installation.

CAUTION
 If you detect a water leak from the water heater at this point, turn off the water supply at the shut off valve on the unit’s incoming water supply and contact us at 1-844-746-6688.

Consult a qualified and licensed electrician if you have questions or are unsure about anything relating to codes for this product. The heater must be connected to a dedicated circuit breaker on the main electrical panel.

WARNING
 As with all electrical appliances, it’s crucial to first shut off all power to the unit directly at the fuse or breaker box before attempting to install, repair or disassemble this water heater. Ensure that the breaker is shut off. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.

CAUTION
 All wiring (wire gauge), as well as circuit protection (breaker), 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 lead to property damage, 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 (check heater specification details below). Before installing this tankless water heater, ensure that sufficient electrical power is available in the home to handle the maximum amperage load of the applicable heater.

IMPORTANT NOTES:
3.5kW, 7kW, and 13kW heaters require 1 set of wire and ground (see wiring diagram on page 11).

• Please see electrical specifications by heater input and wiring diagram on the page 10-11 for additional electrical information.

Electrical Installation

STEP 1: Take the wire pair and connect to the breaker (see wiring diagram). Be sure the power to the unit is shut off using the dedicated circuit breakers in the main electrical panel.

STEP 2: Run the power cable wire from the circuit breaker in the main electrical panel to the water heater by utilizing a suitable wire gauge which meets all applicable electrical codes for the size of the breaker. Then, connect the power cable to the block terminal within the water heater.
STEP 3: Unit requires a ground conductor for the incoming circuit.

STEP 4: DOUBLE CHECK the electrical connections and ensure the wire connections are correct, tight and secure. It’s important to confirm that the right breaker size and wire gauge has been used and that the unit has been connected to a ground in accordance with applicable codes. Be sure to reattach the front cover of the unit with two screws.

STEP 5: Ensure that all the air has been purged from the water lines before turning on power to the unit. Refer to STEP 3 in the plumbing installation section. Restore power to the unit through the dedicated circuit breaker in the main electrical panel.

Operation Guide

Operating your new tankless water heater is similar to using any traditional water heating system. However, it is essential that you carefully read all setup procedures, 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.
This electric water heater is designed to supply hot water. The unit contains heating elements within, capable of heating water quickly on-demand for as long as you need it. Unlike a conventional tank storage water heater, this unit is a tankless water heater that does not store hot water. However, once you begin using the system, you will understand it works like a conventional tank system.
Tankless system delivers hot water instantaneously on demand. Since a tankless system does not waste energy continually when heating water, i.e. idly sitting and losing heat in a storage tank, it provides significant energy savings than a conventional water heater.
With your new system, as soon as you turn on the hot water faucet, the high- power heating elements are activated.
It is essential to keep in mind that all tankless water heaters are subject to a maximum flow rate. If this flow rate is exceeded, the heater will not be capable of sufficiently heating water.
Also keep in mind that conventional tank heaters are set to high temperatures to prevent running out of hot water quickly, and thus a large amount of cold water needs to be mixed in to reach a comfortable level for washing and showering. Since this unit heats water on demand, it is designed to heat to a lower temperature. This means you only need to mix in a small amount of cold water or none at all. Your hot water supply may also be affected by the incoming water temperatures as the season differs. During winter, if the incoming water temperature is frigid, you might not be able to run multiple hot water outlets at the same time as compared to the summer. However, you can run showers back-to-back without having to wait for the water to heat.
Water Quality: One of the things which should be taken into consideration when installing and maintaining the water heater is the quality of water. Water conditions outside the recommended levels outlined below are not permitted and can damage the water heater. We reserve the right to deny any warranty claim regarding damage suffered due to use in water conditions that are not in accordance with the table below. The water must be treated, and the heater flushed regularly when this product is installed in an area that is known to have hard water that causes scale build-up to prevent damage to the heat exchanger and heating elements. We recommend that a water treatment device or water softener should be installed to maintain optimal performance of the water heater in hard water areas.

Open a faucet slightly to cause water to flow continuously through the device at a very low rate, without heating. Restore power to the unit when temperature condition is normal.
If the water inside the heater freezes, it can cause damage that is not covered by warranty. If you suspect water has frozen within the unit, do not turn it on until you are sure the frozen water has melted, and there are no leaks in the unit. It is recommended to contact a qualified electrician or the manufacturer for service in this situation.

Aerator provided with 3.5kW model only

Assembly instructions
For optimal heating performance and proper operation, the provided 0.5GPM aerator must be installed to your sink faucet. This will ensure a continuous flow and consistent, maximum temperature rise. Output temperature will vary depending on seasonality and inlet cold water temperatures Maximum of 0.5 GPM flow rate is needed for optimal heating performance.

Also, DO NOT mail the product back to the manufacturer, nor bring it to a service center without proper instructions and permission from one of our representatives. The terms of this warranty are solely subject to the original owner and are at no time transferable. A transfer of ownership will result in immediate termination of this warranty. This warranty is valid only if the product is purchased from an authorized reseller that has an established direct relationship with the manufacturer. The manufacturer warrants to the original owner that our instant water heaters will be free from defect in workmanship and material for TWO YEARS from the date of purchase, and free from leakage for SEVEN YEARS from the date of purchase. Should any part(s) prove to be defective during this period, the manufacturer will only be responsible for a replacement water heater or replacement of the defective part(s). The manufacturer is not responsible for labor charges or any incidental or consequential expenses. If a replacement water heater or part is not available, the manufacturer’s liability is limited to the cost of the water heater or $1,000.00, whichever is less. The manufacturer is not an insurer, and the original owner should purchase insurance to cover damage to property or belongings. The original owner agrees to waive their right to jury trial or to participate in a class action. Also, the original owner agrees to waive subordination to the extent a loss is covered by insurance, so that their insurance company cannot proceed with action against the manufacturer for recovery of any claims. Furthermore, all requests must be arbitrated in the state of New Jersey. Should the owner wish to return the water heater for repair, the owner must first secure written authorization from the manufacturer. The owner shall be required to show proof of purchase date and to pay all transportation costs to return the defective part(s) or water heater for repair or replacement.
