OPERATING INSTRUCTIONS (CONT’D)
Filter out debris with a pump filter bag. Keep the front of the chiller unit 12” away from
anything and the back 24” away; this will facilitate better cooling. Have a small fan blowing
across the radiator portion of the chiller. Do not overwork your chiller by using in an
environment where the ambient temperature is above 90ºF. This is a ventilation issue that
you should first address.

OPERATING TIPS
A. Find a cool and close place to put the chiller unit; preferably within several feet of the room that
is less than 80ºF.
B. Keep the front of the chiller unit 12” away from anything and the back 24” inches away; this will
facilitate better cooling.
C. Have a small fan blowing across the radiator portion of the chiller.
D. Don’t overwork your chillers; don’t try to use at temperatures above 90ºF. This is a ventilation
issue you should address first. Do not reduce the temperature setting on the chiller
to lower than 40ºF.
E. If in doubt of needed size– get a bigger chiller unit or use two.
F. Filter out debris with a pump filter bag — Very Important!
G.Use appropriately sized pumps; you will need two. One pump is to move water through the
chiller; the other is to move the water through your system. Recommended chiller pump size:
1/10 horsepower unit ~ 132-264 GPH pump
1/4 horsepower unit ~ 600 -1000 GPH pump
1/2 horsepower unit ~ 750-1200 GPH pump
H.Keep the outside of the unit dry.
I. Use a grounded outlet.
J. Operate upright.
K. Dedicate a circuit that has double the needed capacity for the chiller.
L. Do preventative maintenance:
~ Unplug unit before servicing.
~ Clean cooling coils and compressor regularly. Be careful not to damage fins on
radiator. Compressed air works well for cleaning.
~ Lube fan motor with white lithium grease.

TEMPERATURE ADJUSTMENT
D. When refrigerating, the EcoPlus Chiller will stop cooling after the water temperature reaches
the set temperature. The Chiller will restart if water temperature becomes higher due to
environmental temperature.
A. Plug the EcoPlus Chiller into a socket of
rated voltage and frequency, turn it on.
The power switch light will illuminate and
LCD display will show the current water
temperature.
B. To adjust the temperature setting press the " SET"button. The set water
temperature will be indicated on the digital display. Press "p" or "q" to
adjust the temperature to set desired water temperature. The start-up
condition of the machine is as follows: When the actual water temperature
is equal to or greater than set water temperature, the chiller begins working.
NOTE: The starting temperature difference can be adjusted to 2°F, 3°F or 4°F.
Setting the starting temperature difference:
1) Press the “SET” button for ten seconds to enter into the temperature adjustment
function, then press “SET” again to adjust the temperature difference.
2) Press the "p" button and the system will exit in ten seconds displaying the water temperature.
3) Press the "q" button to set the starting temperature difference, you can adjust by 1°F
increments with each press, the starting temperature range is 2°F, 3°F or 4°F.
C. The LCD operating plate resumes showing water temperature two
seconds after set-up is completed. The EcoPlus Chiller will start
working after a 2-3 minute delay.
7
Resetting the temperature tolerance:
1) Press the “SET” button for ten seconds. “CA” will appear on the digital display indicating the
reset function is ready.
2) Press "p" or "q" to reset the temperature by 1°F with each press, the temperature variance
range is +4°F to -4°F
3) After resetting the temperature tolerance, there is no need to press any button, the system
will exit from the reset function after 10 seconds, and the digital display will show the
adjusted temperature.

TEMPERATURE GUIDELINES
WHAT IS THE OPTIMAL TEMPERATURE?
AQUARIUM
Corals come from a variety of ocean environments, the temperature range would be from the low
70s - low 90s. If you have a variety of corals from different environments, a temperature range of
75 - 80 is a safe choice; if in doubt consult your aquarium dealer.
HYDROPONICS
Whether your hydroponic garden is an Ebb and Flow, Top-Feed Drip, Aeroponic, NFT or Deep
Water Culture system; your plants will benefit by maintaining a consistent temperature of 60-70ºF.
Nutrient solutions maintained at 60-70ºF hold much more oxygen than a 75ºF solution. Maintaining
a temperature of 60-70ºF will help control transpiration rates and ensure proper nutrient uptake.
Never let your solution climb above 85ºF. Hot roots attract pests and diseases, as well as significantly
reducing oxygen levels and nutrient uptake.

C. The air filter needs cleaning at least once every month. The EcoPLus
Chiller becomes dirty after being used for extended periods of time.
Accumulated dirt makes the chiller’s exhaustion of heat less
effective. Simply clean by washing the filter in clean
water, or remove the dirt with a vacuum cleaner.
STORING THE ECOPLUS CHILLER
A. When chiller is not in use,
discharge remaining water in pipes.
Store chiller in safe place.
MAINTENANCE
CLEANING THE AIR FILTER
A. IMPORTANT! Disconnect the power. B. Pull down air inlet grill from the top and take out filter.

TROUBLESHOOTING
A. If the chiller stops refrigerating properly or refrigeration stops after a long period of time, refrigerant
may be necessary. Ask a certified and licensed technician to check the chiller for the appropriate
amount of refrigerant. If refrigerant is low, have technician add the proper amount of refrigerant.
B. If air temperature and water temperature are too high, the compressor will stop to protect the
chiller from over-heating.
C. If display does not function or machine does not work, please check to see if the plug is connected
properly. Also check to see if fuse is broken and whether it needs replacing. You may also check your
home’s breaker box. If you have overloaded the circuit, you may have tripped a breaker.
D. If machine stops working properly under normal operating conditions. DO NOT dissemble the
chiller yourself. Take it to a certified and licensed technician for repair.
