5. Use the /\ or \/ button on the control panel to increase or decrease this setting to the desired
deadband width. Press and hold the SET button again for 5 seconds (or wait for approximately 8
seconds) to confirm the desired temperature and exit from the setting mode to the display mode.
The display will turn from blinking to solid.
6. The deadband setting range is 1-4 degrees Fahrenheit or 1-2 degrees Celsius.
BOOST FUNCTION
1. The boost feature accelerates the chilling process with two available options: 2-hour expedited
maximum chilling and continuous (24 hrs/day, 7 days/week) maximum chilling.
2. To engage the boost feaure, press BOOST once. The LED on the left marked “2 hours” will light.
The boost function is now set to accellerate chilling for 2 hours, after which boosted chilling will
stop and the chiller will return to the regular setting.
3. To set the boost function to constant operation, press BOOST twice. The LED under “24/7” will
light. The chiller will now continue in boosted mode until the BOOST pad is pressed again.
COMPRESSOR PROTECTION MODE
The refrigeration compressor will automatically turn off when the water reaches, or is below, the
set temperature. After the compressor turns off, it will stay off for approximately 3 minutes.
CLEANING AND MAINTENANCE
We recommend that you flush the internal chiller components at least once every 1-2 months to
ensure optimal performance and efficiency. Over time, nutrient deposits and other debris may
accumulate inside the chiller, reducing its effectiveness.
Note: Do NOT use soap or detergents for cleaning the internal components of the chiller system
(Fig. 1). Do not spray or soak the unit with water to clean it (Fig. 4).
1. Disconnect (unplug) the chiller and submersible water pump from the power supply. Clean the
chiller housing by using moisture towels (Fig.3).
2. Clean off the pump with a high powered hose or sprayer to remove the debris and dirt from the
pre-filter and housing.
3. Reconnect the pump to the chiller inflow tubing and place it in a clean reservoir.
