Thank you for purchasing the Acve Aqua Series Chiller. The chiller represents a signicant
step forward in horcultural chiller engineering, oering state of the art technology at highly
compeve prices. With this chiller, water temperatures for reservoirs can be quickly and
economically maintained. The super silent design results in signicantly lower noise levels which
are quieter than any other similar chillers. The Acve Aqua Series Chillers have a strong chassis
with an ABS plasc housing which is an-rust and an-corrosive, ensuring that the chiller does
not look out of place in any seng. For a complete understanding of this chiller, we recommend
reading this instrucon manual thoroughly.

Several symbols are used in this manual and on the product itself which are aimed at promong
proper and safe operaon in order to prevent personal injuries or damage to the chiller. Please
familiarize yourself with the symbols below before reading the manual or trying to operate the
chiller.

Hazard levels will be indicated in wring or shown by pictures. The symbol on the le provides
general emphasis of the hazard, but specic details of the acon which must be taken will be
shown by a picture or explanaon near the symbol.
This term indicates the possibility that connuing to operate the chiller while ignoring this
warning or operang the chiller incorrectly, may cause personal injury or equipment damage.
This symbol advises you of a potenal hazard which should be noted (including danger and
warning).
This symbol advises you of a mandatory acon which must be taken in order to avoid danger.

1. Do not install the chiller outdoors. (Fig. 1)
2. Place the chiller in a venlated space away from ammable materials, high temperatures, direct
sunlight, moisture, and dust. (Fig. 2)
3. Place the unit on a stable horizontal surface. (Fig. 3)

INSTRUCTIONS
www.Hydrofarm.com 12
4. Install at least 12-16 inches (30-40 cm) away from walls in order to give the chiller adequate
venlated space. (Fig. 4)
5. Do not cover or move the chiller while it is operang.
6. The circulaon water ow of the chiller is indicated in the technology parameter table. This chiller
does not have a water pump, so it needs a pump with an available external lter. Using a pump
without an external lter may cause a water leak or other damage. (Fig. 6)
7. Do not put the chiller on its side or upside down as this will cause damage to the chiller. If the
chiller is placed on its side, readjust the unit to its correct upright posion and wait 20 minutes
before turning it on. (Fig. 7)

1. Remove the chiller unit and all of the contained hardware from the box and packaging material.
2. 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.
3. Install the inlet/outlet ngs onto the inow and oulow threaded sites
NOTE: If the inow and oulow ngs are dierent sizes, typically the larger one is used on the
inow and the smaller one on the oulow.
4. Aach the desired length of tubing onto each inow and oulow ng adapter with the worm
drive hose clamps. The inow should connect the chiller to the appropriate sized submersible
water pump, such as an Acve Aqua Water Pump, in the proper sized reservoir 

NOTE: Please note that the lter (with the pump) must be located below the reservoir water level.
If you wish to place the unit at the side of the reservoir, you must ll the ltraon system with
water before turning it on.

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.

• Do NOT cover the chiller unit with anything during operation.
• Place the chiller in the upright position ONLY for operation and storage purposes.
• Avoid direct contact with liquids to the external body of the chiller unit. Failure to do so may
result in damage to the unit or electric shock.
• Keep power cord free of obstructions, such as heavy or sharp objects sitting directly on it.
• This chiller is approved for indoor use ONLY.
• Keep the unit away from flammable vapors, direct sunlight, high temperature exposure, and high
humidity.
• Do NOT submerse the chiller. Doing so will damage the unit and may inflict electric shock.
