COMPRESSOR OPERATION:
The refrigeration compressor will automatically turn off when the water reaches, or is below, the set
temperature. When the compressor turns off, it will stay off for approximately 3 minutes or until the
water is 1 degree above the set temperature.
An indicator light in the top right portion of the display will appear when the compressor is active. The
indicator light will disappear when the set water temperature has been reached, and will blink when
the compressor is in the 3 minute protection mode.
ERROR CODE:
Certain text will appear on the display panel in the event of an error. “P1” is an example that means
there is a defect in the temperature sensor. If error codes are appearing on the display, return the unit
to the original place of purchase for a warranty assessment.
CLEANING AND MAINTENANCE
Flushing of the internal chiller components is recommended at least once every 1-2 months to ensure
optimum performance and efficiency. Over time, nutrient deposits and other debris may accumulate
inside the chiller, reducing its effectivness.
Note: Do NOT use soap or detergents for cleaning the internal components of the chiller system.
1. Disconnect the chiller and submersible water pump from the power supply.
2. Clean off the pump with a high powered hose or sprayer to remove debris and dirt from the pre-
filter and housing. Clean the pre-filter as well if one is used.
3. Reconnect the pump to the chiller inflow tubing and place it in a clean reservoir.
4. Fill the reservoir with clean water and a flushing agent formulated to remove salt deposits and
excess nutrients from the plant system and grow medium (available at most indoor gardening and
hydroponic retailers). Note: Using a flushing agent is completely optional.
5. Plug in the pump and allow it to run for at least 1 hour so that the projected solution contacts all
of the internal components used in the chiller during operation. Unplug the pump and empty the
reservoir solution.
6. Repeat steps 4 and 5 with clean water ONLY.
