NOTES:
1 . Rate of flow is determined by several factors, including size of pump, height of chiller above water pump, size of fubing
and any kinks, dogs or other obstnctions to water llow.
2. Performance tests were done with an ambient room temperature of 86'F (30'C), water temperature (before refrigeration)
ol82"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 Performan@ Curves on Page 4).
3. When the volume of water to be refiigerated is reduced and/or the water and ambient room temperatures are lower,
cooling rate and effciency will be increased.
4. Reftigeration efficienry is determined according to the installation location, lighting, heat source(s), pump, filter and
other connecting parts. For greatest efficiency, EcoPluso pumps and parts should be used.
5. lf there is not enough air exchange in the room where chiller is instialled, refiigeration effciency may be reduced.

UiIPACKII{G THE GHIIIER
Please D0 NOT dispose of any packaging until you have checked that all parts are included and
the chiller is operational. ln the unlikely event of missing parts or damage, conkct the retailer
where you purchased the unit imnediafel12 Do not leave children unattended with the chiller or
packaging. Disposal ol all materials must be canied out responsibly, salely and recycled
wherever possible.
Package Gontents:
. 1 Chiller Unit o 4lnlet/0utlet Adapters with Nuts and Rubber Seals
o 'l lnstruction Manual . 1 Spare Fuse
INSTALLING THE GHILLER
For best results and safest operation, installthe chiller indoors in a well ventilated location.
MPONTANT!
o Provide a grounded power outlet and circuit to be used only for the chiller (any electrical work
must be done by a qualified electrician).
r Power source must conlorm to the power requirements specilied on the product nameplate.
o ALWAYS disconnect the power supply when installing or cleaning the chiller.
D0 NOT install outdoors. Keep out of direct sunlight
and away from flammable
materials, moisture,
dust and any heat
s0urce.
0perate only on
a flat, stable,
horizontal surface.
Clearance: allow at least B" (20cm)
in front; 16" (40cm) in rear. Never cover during operation.
Avoid banging or shaking. Do not knock the chiller over or turn it upside down - this may cause
damage to the refrigeration system. lf unit is
tipped or knocked over, turn the power 0FF. a(
Set the unit upright and level again and
wait 20 minutes before switching it back on.

nis chilla does ll0l haye an internal panp for systen circulation.
An apprupriately sized exterml panp is reqaired.
GHOOSING THE CORRECT EXTERI{AL PUMP
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:
Ghiller
Model Max. Reseruoir Uolume
Gallons (Liters) Rate ol Glrculation - Pump Size
Gallons Per Hour (Liters Per Hour)
1/10 HP
114 HP
112 HP
66 - 317 GPH (250 - 1200 LPH)
264 - 660 GPH (1000 - 2500 LPH)
317 - 7e3 GPH (1200 - 3000 LPH)
TYPICAL INSTALLATION
For the most effective water cooling and energy efficiency, locate chiller belowwaler level. lf 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).
IMPORTANT! Always check the following before starting chiller:
/ Water level inside the reservoir is correct and there are n0 leaks in any hoses 0r connections.
/ Power supply is correct and the plug is inserted completely into the outlet.
/ Double-check the whole system to make sure there are n0 breaks 0r clogs.

Setting Water Tempetature: 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 ll0t{ll key to enter a new temperature setting from 3z-90"F (3-32'c). To accept, press the sET
button again (or just wait about B seconds and it will automatically store your new setting and
revert t0 normal operation). The actual water temperature displhys continuously while the chiller
is working. To Compare Actual and Set Water Tenperatures: 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 Tempetatule Gontrol: When the compressor stops for over 3 minutes and water
temperature rises 1'F above the set temperature, the chiller will automatically restart. 0nce 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.
SPECIAL FUNCTIONS AND PROTECTION DEVICES
o lemq. Display Adiuslment: lf necessary, the display of actual water temperature can
be adjusted 2.4"F (1.5"c) up or down. Press the uP and lt0wll keys at the same timelor
6 seconds until the numerical display flashes. Then, press the uP or ll0l{ll keys to adjust.
. compressor Protection: lf the compressor somehow becomes overloaded, a protection
device will automatically shut it off, then attempt a restart after about 3 minutes.
c Sensor Circuit Protection: lf 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.

CLEA}IING THE GHILLER
For ufe, efficient operation and long service life, it is essential to regularly clean the chiller and all
hoses, connections and other componenb in the system in which it is installed. Thorough cleaning
is recommended every 1-2 months, including:
o 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 inmerse the chiller in water or spray it down with a hose!
o 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 0n attached filter and remove (Fig. 3 & 4).
4. Lift bottom clips and pull out to remove side filters (Fig. 5- 1/4 & 12 HP Models only).
5. Loosen screws 0n 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 belore reinstalling them.
STORING THE GHITLER
Disconnect chiller from the system. Gently tilt the unit to drain water out through the inlet and
outlet connections. D0 NOT INVERT CHILLER T0 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.
