Safety Information
1
To prevent injury to user, others and/or property damage, the following safety instructions must be
followed. Ignoring these instructions may cause harm or damage due to faulty operation.
Seriousness is indicated by the following symbols:
• Do not exceed the rating of the power circuit or share the outlet with other appliances.
• Do not start or stop the chiller by switching the power source on/off or by plugging or
unplugging the power cord.
• Always use the factory-installed 3-prong, grounded, polarized power plug and cord.
• Never attempt to operate chiller with a damaged or modified power cord.
• Do not insert or remove plug from outlet with wet hands or standing in water.
• Do not place chiller near a heat source, flammable materials or hazardous chemicals.
• Disconnect the power if strange sounds, smells or smoke come from the unit.
• Never attempt to take apart or repair the chiller yourself. Repairs must be done by factory
authorized service personnel.
• Before cleaning the chiller, always turn off the power and unplug the power cord.
• Do not drink or use any water drained from the unit.
WARNING!
Possible death or serious injury.
CAUTION
Possible injury or property damage.
WARNING!
• Do not install chiller in closets, cabinets or other small spaces.
• Do not place chiller where water may splash or leak onto the unit.
• Never cover the intake or exhaust openings with clothes, towels or other objects.

NOTES:
1. Rate of flow is determined by several factors, including size of pump, height of chiller above water pump, size of tubing
and any kinks, clogs or other obstructions to water flow.
2. Performance tests were done with an ambient room temperature of 86˚F (30˚C), water temperature (before refrigeration)
of 82˚F (28˚C), and a total water volume of 42 gallons (160L) with 1/10 HP model; 80 gallons (300L) with 1/4 HP model;
and 132 gallons (500L) with 1/2 HP model (see Performance Curves on Page 4).
3. When the volume of water to be refrigerated is reduced and/or the water and ambient room temperatures are lower,
cooling rate and efficiency will be increased.
4. Refrigeration efficiency is determined according to the installation location, lighting, heat source(s), pump, filter and
other connecting parts. For greatest efficiency, EcoPlus®pumps and parts should be used.
5. If there is not enough air exchange in the room where chiller is installed, refrigeration efficiency may be reduced.

wherever possible.
• Provide a grounded power outlet and circuit to be used only for the chiller (any electrical work
must be done by a qualified electrician).
• Power source must conform to the power requirements specified on the product nameplate.
• ALWAYS disconnect the power supply when installing or cleaning the chiller.

Installation

Required pump size depends on chiller model, water volume and rate of circulation. Recommended
pump sizes for effective water chilling are within the following ranges:
CHOOSING THE CORRECT EXTERNAL PUMP
Water level inside the reservoir is correct and there are no leaks in any hoses or connections.
Power supply is correct and the plug is inserted completely into the outlet.
 Double-check the whole system to make sure there are no breaks or clogs.
For the most effective water cooling and energy efficiency, locate chiller below water level. If chiller
must be placed above reservoir level, make sure height above pump does not exceed 26 ft. (8m).
For best performance, keep hoses as short as possible. The sum of all hose lengths should not
exceed 25 ft. (7.6m).
TYPICAL INSTALLATION
This chiller does NOT have an internal pump for system circulation.
An appropriately sized external pump is required.

SPECIAL FUNCTIONS AND PROTECTION DEVICES
• Temp. Display Adjustment: If necessary, the display of actual water temperature can
be adjusted 2.4˚F (1.5˚C) up or down. Press the UP and DOWN keys at the same time for
6 seconds until the numerical display flashes. Then, press the UP or DOWN keys to adjust.
• Compressor Protection: If the compressor somehow becomes overloaded, a protection
device will automatically shut it off, then attempt a restart after about 3 minutes.
• Sensor Circuit Protection: If the water temperature sensor has an open or broken circuit,
the chiller will shut down and a “P1” or “P2” error message will be displayed.
Operation
6
USING THE DIGITAL CONTROL PANEL
Setting Water Temperature: To enter a temperature setting, press the SET button and hold
for more than 3 seconds. The previously set temperature will appear on the display. Press the UP
or DOWN key to enter a new temperature setting from 37-90˚F (3-32˚C). To accept, press the SET
button again (or just wait about 8 seconds and it will automatically store your new setting and
revert to normal operation). The actual water temperature displays continuously while the chiller
is working. To Compare Actual and Set Water Temperatures: Press the SET button once. The set
temperature will appear, alternating with a display of the actual water temperature (when actual
water temperature is displayed the “Cooling” indicator light goes OFF – when the set
temperature is displayed the same indicator FLASHES).
Automatic Temperature Control: When the compressor stops for over 3 minutes and water
temperature rises 1˚F above the set temperature, the chiller will automatically restart. Once the
set water temperature is reached, the “Cooling” indicator light will go off and the compressor
will stop. NOTE: The “Cooling” indicator light will also flash if any protection device (see below)
is activated for at least 3 minutes.

CLEANING THE CHILLER
STORING THE CHILLER
For safe, efficient operation and long service life, it is essential to regularly clean the chiller and all
hoses, connections and other components in the system in which it is installed. Thorough cleaning
is recommended every 1-2 months, including:
• Rinse collected debris from filters, external reservoir pump, all inlet and outlet connections,
hoses, etc., with clear, lukewarm water. Soap, detergent or bleach is NOT recommended because
any remaining residues can contaminate the nutrient solution. The chiller housing, digital
control panel, power switch and other external surfaces must be cleaned with a soft, dry cloth.
NEVER immerse the chiller in water or spray it down with a hose!
• Clean air filters every 2 weeks:
1. Loosen screw on front cover, turning counterclockwise (Fig. 1).
2. Gently pull cover toward you to remove (Fig. 2).
3. Loosen screws on attached filter and remove (Fig. 3 & 4).
4. Lift bottom clips and pull out to remove side filters (Fig. 5 – 1/4 & 1/2 HP Models only).
5. Loosen screws on attached filters and remove (Fig. 6 & 7)
6. Remove dust with a brush or vacuum cleaner, or rinse well in lukewarm water (Fig. 8).
Make sure filters are thoroughly DRY before reinstalling them.
Disconnect chiller from the system. Gently tilt the unit to drain water out through the inlet and
outlet connections. DO NOT INVERT CHILLER TO DRAIN! Clean and dry filters, wipe down external
surfaces with a soft cloth, cover with plastic bag, insert into carton and store in a safe, dry place.
Always make sure unit is unplugged before performing any cleaning!
