10
POSSIBLE CAUSE
• Unit is boiling.
May be normal during initial setup.
• The unit is unplugged.
• The electric outlet is inoperative.
• Thermostat is not adjusted to
your needs.
• The thermostat may be set too
high.
• The expansion chamber isn't
draining properly due to low
water pressure.
• The spout is blocked.
WHAT TO DO
• Activate faucet lever to release some water from the tank.
• Adjust water temperature using dial on tank front.
Remember that at higher altitudes,water boils
at lower temperatures.
Make sure the unit is connected to a properly grounded
•
electric outlet.
Make sure the circuit breaker or fuses are functioning
•
properly.
•
Check that the outlet is not switched off and that the
outlet has power.
Turn the temperature control dial to a warmer setting,
•
wait 15 minutes and recheck the water temperature.
Repeat if necessary
• Adjust the thermostat by turning the dial clockwise to
raise temperature or counter clockwise to reduce
temperature. Then activate faucet lever 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.
• Turn temperature control dial counterclockwise.
•
Check that the hose connecting the faucet to the hot
water dispenser tank is not clogged, twisted, or kinked.
• Unplug the unit. If the dripping doesn't stop after a few
minutes, check the supply valve to ensure that is fully
open and there are no obstructions in the water line
reducing the pressure below 15 psi (i.e.,a poorly
mounted saddle valve, a clogged water filter, or a
partially opened shut-off valve).
• Unscrew spout end piece and clean out any debris.
Check for proper installation of tubing from faucet to
•
dispenser tank and faucet to water line. If connected
backwards or cross-connected, valve may be damaged.
