This section is for professional use only for installation, adjustment and service.
Danger of fire or electric shock, do not open panels. No user serviceable parts inside.
All adjustments and service to be performed by authorized professional personnel
To adjust the temperature for high altitude installation:
Thermostatic control is factory set to the maximum temperature: 200°F and is adjustable to the lowest setting
of 180°F. The capillary thermostat is rated within 5% of this range.
To correct for boiling at high altitudes the thermostat may be adjusted to a lower setting.
1. Unplug the power cord.
2. Remove the back cover.
3. Locate the thermostat:
4. Turn the adjustment to the left to decrease the temperature
{Minimum is 180°F/Maximum is 200°F}
5. Reinstall back cover and plug into the power outlet.
6. Brew, refill and re-check the temperature after the "READY" light is on.
Thermostat adjustment
Left to lower & Right to raise.
Make small, incremental changes.
Check temperature after "READY" light is on.
NOTE: at some high elevations it may be required to set thermostat all the
way down, and raise it back only slightly to compensate for boiling.
Adjustment is accurate to +/- 5%.

LIMING
To prevent liming problems in tank fittings remove sprayhead and insert deliming spring all the way into the
tank. When inserted into tank properly, no more than ten inches of the spring should be visible at the
sprayhead fitting. Saw back and forth five or six times. This will keep fittings open and clear of lime. In hard
water areas this should be done everyday. This process takes approximately one minute. In all areas the
sprayhead should be cleaned at least once a week. Where bad liming has already occurred, a new complete
tank assembly may be installed. The tank may be changed in approximately 5-10 minutes time.
