Care and Use Guide

Adjusting the Thermostat

Factory temperature pre-set is approximately 200˚F.

  • Adjust the thermostat slowly, turning the dial clockwise to increase temperature or counter clockwise to decrease temperature, then activate faucet handle for 20 seconds to bring in fresh water to be heated at the new setting. Allow 5-7 minutes for water to reach new temperature.

To reset the thermostat to 200°, turn the indicator two notches to the right of vertical.

Seasonal Storage/Drainage

Anytime the instant hot water dispenser is not used for extended periods of time, unplug and drain unit. If it is below freezing you will need to unplug the unit and drain it.

  • Disconnect power from unit (unplug unit).
  • Push hot water dispenser faucet lever and allow water to flow until it is cool.
  • Shut the cold water supply off at the valve.
  • Disconnect tubes from the tank.
  • Unhook tank from wall.
  • Hold tank upside down and drain the water into the sink.
  • Towel dry any water drippings from tank area.
  • Reinstall tank to wall and reconnect tubes.
  • Remove and discard filter cartridge, if applicable.
  • To put back into working order, install new filter cartridge (if applicable) and turn on cold water supply at valve. Depress the hot water dispenser faucet lever and hold until water flows from the spout. Reconnect the electrical cord.

Cleaning the Faucet and Tank

  • Only use mild cleaners to clean the faucet and plastic components.
  • Cleaners with acids, abrasives, alkaline or organic solvents will result in deterioration of the plastic components and void the warranty.

Property Damage

  • Regularly inspect the unit for any signs of leakage. If there are signs of water damage, immediately remove the unit from service.
  • To avoid water damage from leakage, replace all cut, loose or split tubing.
  • A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage.

Personal Injury

  • Regularly check for signs of corrosion by examining the appearance of the dispensed water.
  • If there is any discoloration or rusty appearance, unplug and drain unit as described in the Seasonal Storage/Drainage section on this page of the manual.
  • If the water discoloration remains after draining and refilling unit, discontinue use and contact an authorized InSinkErator service agent.
