Assembly Instructions:
Remove the chiller unit and all of the contained hardware from the box and packing
material.
Set the chiller unit upright in the desired area on a stable surface ensuring there is at
least 1 of clearance around the body (sides, top, and back) of the unit.
Install the inlet/outlet fings onto the inflow and oulow threaded sites.
SETUP AND TROUBLESHOOTING GUIDE SUMMARY
Operation:
1. Do NOT power on the chiller unit yet. Fully submerge the water pump to be used, plug it
in, and ensure that water is moving freely between the holding reservoir and the chiller unit.
2. Plug the chiller into a grounded outlet and ensure the power switch located on the back
of the unit is in the “ON” (I) posion.
Note: If the inflow and oulow fings are of different sizes, typically the larger one is used
on the inflow and the smaller one on the oulow.
4. Aach the desired length of tubing onto each inflow and oulow fing adapter with
the worm drive hose clamps. The inflow should connect the chiller to the appropriate
sized submersible water pump,
in the proper sized reservoir see aƩached performance
chart The oulow tube should hang freely in the reservoir to reintroduce the chilled
water back into the holding tank.

www.hydrotek.ca
SETUP AND TROUBLESHOOTING GUIDE SUMMARY
Setting The Temperature:
1. Press and hold the SET buon down for approximately 3 seconds to enter the water
temperature programming mode. The previous water temperature seng will display.
2. Use the /\ or \/ buons on the control panel to increase or decrease the desired water
temperature. Press the SET buon once more, or wait approximately 8 seconds to
select the desired temperature.
Temperature Display:
•Press the SET buon once to display the current set temperature value of the chiller
unit; press it again to display the actual temperature value of the water. The blinking
display indicates the set temperature.
Temperature Error Adjustment:
1. When the reservoir water temperature differs from the set temperature value, an “II”
indicaon should appear in the display.
Press and hold the /\ and \/ buons at the same me for approximately 6 seconds to
enter the error adjustment programming. The display will blink once this status is acve.
By pressing either the /\ or \/ buons, the error adjustment range can be modified
+/-1.5 degrees Celsius. DO NOT USE THIS FUNCTION IF IT IS NOT NECESSARY
Fuse Replacement:
1. Detach the power cord from the chiller. The fuse compartment is underneath the power
cord socket located on the back of the unit.
Remove the notched fuse slide from the compartment by pulling it straight out. A small
screwdriver or pointed tool may be needed to remove the slide.
Check the fuse and internal compartment for damage (e.g. blown fuse, melted terminals, etc.).
Replace the fuse if necessary and retry the operation.
Compressor Operation:
The refrigeraon compressor will automacally turn offwhen the water reaches, or is below,
the set temperature. When the compressor turns off, it will stay offfor approximately 3
minutes or unl the water is one degree above the set temperature.
An indicator light in the top right poron of the display will appear when the compressor is
acve, disappear when the water temperature has been reached, and blink when the
compressor is in the 3 minute protecon 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 opmum performance and efficiency. Over me, nutrient deposits and other debris
may accumulate inside the chiller, impeding the operability.
To prevent clogging and minimize maintenance, we recommend use of our 6" or 10" filter bag
with your submersible pump.

www.hydrotek.ca
SETUP AND TROUBLESHOOTING GUIDE SUMMARY
Note: Do NOT use soap or detergents for cleaning the internal components of the chiller system.
Disconnect the chiller and submersible water pump from the power supply.
Clean offthe 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.
Reconnect the pump to the chiller inflow tubing and place it in a clean reservoir.
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 oponal as stated in step 4.
5. Plug in the pump and allow it to run for at least 1 hour so that the projected soluon
contacts all of the internal components used in the chiller during operaon. Unplug the
pump and empty the reservoir soluon.
6. Repeat step 4 and 5 with plain water ONLY.
7. Remove the front grill from the unit so the air inlet filter is accessible. Clean both with a
vacuum and/or brush.
8. Replace the air inlet filter and grill to the front.
Special Notes and Instructions:
•The cooling efficiency of this unit is relave to the surrounding environment i.e. install
locaon, ambient air temperature, addional heat sources (grow lights, pumps, CO2
generators, air condioners, dehumidifiers, etc.), and any other connecng parts that
may impede the chiller’s operaon. Insufficient air exchange of the room the chiller is
occupying will reduce the operaonal efficiency if the ambient air temperature rises
due to heat output from the chiller and/or other equipment.
•Follow the GPH (gallon per hour) recommendaons so that the appropriate size pump
may be implemented. A pump that is either too weak or too powerful may impede the
operaon. Vercal distance between the pump and the chiller will affect the size of
pump that is needed. For example, if the pump only needs to project water 2' to get the
chiller unit as opposed to 10', a smaller one can be used.
•We recommend that the power source support ONLY the chiller unit and no addional
appliances in order to prevent a power surge or circuit overload.
•Remote operation of the chiller unit outside of the grow space will reduce the amount
of heat generated within the garden.
