INSTALLATION GUIDE AND OWNER’S MANUAL

KwickShot® Tankless Electric Water Heaters

Read and understand the instructions thoroughly before attempting the installation or service of the water heater. Failure

to follow the instructions can result in serious injury, death and/or property damage. The warranty of the water heater will

depend upon proper installation according to the instructions. Some heaters come supplied with separate faucet aerators.

If supplied, the aerator must be installed in the faucet for optimum performance. The heater must only be used to heat

water and must be installed in a location where it is not subject to freezing temperatures. The manufacturer is not liable for

any damages resulting from improper installation or misuse.

The installation must conform to the latest requirements of the National Electrical Code and all applicable state and local

codes. This information is available through local authorities. You must fully understand the requirements before

beginning this installation.

This water heater is not required by UL 499 to employ a temperature and pressure relief valve (T&P). Check with local

codes to find out if one is required. If it is, the T&P valve must be installed in the outlet hot water pipe between the heater

and the isolation valve.

IMPORTANT SAFETY INSTRUCTIONS

When using electrical equipment, basic safety precautions should always be followed, including the following:

READ AND FOLLOW ALL INSTRUCTIONS

Supply the water heater only from a grounded system. A green terminal (or a wire connector marked “G”, “GR, “Ground”,

or “GROUNDING”) is provided for wiring the appliance. To reduce the risk of electric shock, connect this terminal, or

connector, to the grounding terminal of the electric service or supply panel with a continuous copper wire. Connection

should be made in accordance with the electrical installation code.

BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THE

HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.

For optimum performance, Bradford White recommends the use of isolation valves (full flow ball type) on the inlet and outlet pipes and a 40 mesh Y-Strainer on the inlet of the heater. Clean the screen periodically for best performance. BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED. The heater’s water INLET and OUTLET are labeled.

Sample installation diagrams: Note: KwickShot® Thermostatic Models only Open the hot water faucet and run water for a minimum of 60 seconds and until the flow is continuous and free of air pockets. Close the faucet and install the aerator (if supplied). Failure to install aerator will result in less-than-favorable heater performance. **ML thermostatic models are designed to deliver a flow of 0.35 GPM to each lavatory. Please install the supplied aerators to ensure maximum heating performance.

SECTION 4: ELECTRICAL HOOK-UP BEFORE BEGINNING ANY WORK ON THIS INSTALLATION, CONFIRM THE ELECTRICAL BREAKER IS “OFF” AND THAT ALL MOUNTING AND PLUMBING WORK HAS BEEN COMPLETED PER THE STATED INSTRUCTIONS. For use on an individual branch circuit only. The heater shall be installed using insulated, UL listed, 2 wire cable (2 wire plus ground) of the appropriate size suitable for up to 75°C and protected by the correctly rated circuit breaker.
PAGE 8
Power cable entry to the heater should be made through one of the knock-out holes located on the back plate or top/bottom ends of the unit. Use the appropriate strain relief fitting. The power leads are to be secured to the L1 and L2 or L and N connectors on the terminal block or relay. The ground lead is to be secured to the GND connector on the block or the green ground wire with the provided wire nut. FAILURE TO GROUND THE SYSTEM MAY RESULT IN SERIOUS INJURY, DEATH AND/OR PROPERTY DAMAGE.

SECTION 5: COMMISSIONING THE HEATER 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. Verify water is flowing through the faucet. Switch “ON” the electric power supply at the breaker.
