INSTALLATION GUIDE AND OWNER’S MANUAL

WARNING
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THE HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.

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.

SAVE THESE INSTRUCTIONS

• Hot water can be dangerous, especially for infants or children, the elderly, or infirm. There is hot water scald potential if the thermostat is set too high.
• Water temperatures over 125° F (51° C) can cause severe burns or scalding resulting in death.
• Hot water can cause first degree burns with exposure for as little as:
  • 3 seconds at 140° F (60° C)
  • 20 seconds at 130° F (54° C)
  • 8 minutes at 120° F (48° C)
• Test the temperature of the water before placing a child in the bath or shower.
• Do not leave a child or an infirm person in the bath unsupervised.

GENERAL

Bradford White offers thermostatic, and flow controlled tankless electric water heaters. KwickShot® thermostatic heaters are designed to accept cold or preheated water and heat it to temperatures suitable for normal domestic usage up to a maximum temperature setpoint of 140°F. “ML” option models: Factory set to a maximum temperature setpoint of 110°F and are recommended for multi- lavatory handwashing applications – refer to section 3 for supplied aerator details. “CA” option models: Manufactured for Canadian market and it indicates evaluation and compliance to either Underwriters Laboratories (UL) or Intertek (ETL) under CAN/CSA-C22.2 No. 64/No. 88. KwickShot® flow-controlled heaters are designed to take in cold water and heat it to temperatures suitable for handwashing and other fixed-flow applications.

NOTICE: KwickShot® tankless electric water heaters are tested @ 125 deg. per Department of Energy (DOE) 10CFR Part 430, Energy Conservation Program for Consumer Products. To obtain optimum performance and energy savings, the water heater should be located as close as possible to the point-of-use. The unit is supplied with compression rings and nuts suitable for direct coupling to 3/8” copper or PEX™ piping. Do not use additional screwed fittings, pipe dope or Teflon tape – doing so will void the warranty. DO NOT SOLDER PIPES WHILE THE UNIT IS INSTALLED as serious damage to the heater will result and the warranty will be voided

MOUNTING THE UNIT TO THE WALL

CAUTION

THIS HEATER MUST BE INSTALLED IN A LOCATION WHERE IT IS NOT SUBJECT TO FREEZING TEMPERATURES.

The heater should be mounted on the wall under the sink, as close to the point-of-use as possible. Ideal position is fittings pointed down; however, the heater may be mounted in any orientation.

Note: an additional logo decal has been provided to ensure branding is clearly displayed in any mounting orientation.

• Remove the cover and fasten to the wall using the mounting holes at each corner of the back plate. Replace the cover.
• Minimum turn on flow rates are family dependent:
  • Thermostatic Models: 0.2 GPM
  • Flow Controlled Models: vary by model (refer to the table below)
• Minimum/maximum working pressure: 30 PSI/150 PSI (Optimal operating pressure range: 35 to 80 PSI)

PLUMBING HOOK-UP
The water heater is supplied with 3/8” brass compression fittings that are compatible with either copper or plastic pipes. Make sure these fittings are used for this installation. Contact your representative for further information.

CAUTION

• NEVER SUBSTITUTE THREADED PIPE FITTINGS USING PIPE DOPE OR TEFLON TAPE AND NEVER SOLDER ANY PIPE CONNECTIONS WHILE ATTACHED TO THIS HEATER AS DAMAGE TO THE HEATER WILL RESULT. DOING THIS WILL VOID THE WARRANTY!

Bradford White strongly recommends that the heater be supplied directly from the main cold-water trunk line when possible. This helps to avoid a potential water flow interruption to the water heater which could lead to a failure of the heating element.

System Requirements

• Special suffixed models (i.e. CA, ML), will have identical temperature rises as their base model 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.

WARNING

• BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER, MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.

Sample installation diagrams

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.

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.
