WARNING
To guard against injury, basic safety precautions should be observed, including the following:
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
DANGER
To avoid possible electric shock, special care should be taken since water is employed in the use of
aquarium equipment. For each of the following situations, do not attempt repairs by yourself. Contact
Current-USA or discard the appliance.
• If the appliance falls into the water, or water drips onto the unit, DON’T reach for it! First
unplug it and then retrieve it. If electrical components of the appliance get wet, unplug the
appliance immediately.
• Always unplug appliance from an outlet when not in use, before putting on or taking off
parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug fully
and pull out to disconnect.
• Carefully examine the appliance after replacement. It should not be plugged in if there is
water on parts not intended to be wet.
• Do not operate any appliance if it has a damaged cord or plug, or if it is malfunctioning or
has been dropped or damaged in any manner.
• If you are using the ultraviolet sterilizer or heater upgrade do not operate the unit without
continual water flow.
• If you are using the heater option ensure that the heater is plugged into the thermostat that
is supplied with the water chiller.
• Exposing chiller/power cords to water may cause electrical short and fire.
• Do not allow water or salt to come in contact with thermostat or power cords.
• Do not operate chiller without water flow to the unit. This may cause the evaporator housing
to freeze up and result in damage to the unit.
• Failure to install the sensor into the sensor port may cause an inaccurate temperature
reading and may cause damage to the chiller.
SAVE THESE INSTRUCTIONS
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
To comply with the National Electrical Code (NFPA 70), and to provide additional protection from the
risk of shock, this unit MUST be connected to a ground fault circuit interrupter (GFCI) outlet at all times.
Do not use extension cords. WARNING – To reduce the risk of electrocution, keep all connections dry
and off the ground. Do not touch plug with wet hands.

1. Before removing your Prime Chiller from the box, please note any exterior shipping damage
to the box. It is strongly recommended to keep the box and packaging material in the
unlikely event there is shipping damage or service is required.
2. Remove the chiller and controller from the box and inspect thoroughly for any signs of
damage, even if the box does not show damage. If you notice any damage (cracked or bent
cover, damaged condenser, fins, etc...) please stop and contact your dealer immediately.
3. Remove the 8 screws that hold the front cover in place and tilt the chiller up to remove
the wooden brace from underneath. The wooden brace is used to secure the motor during
shipping. Keep wooden brace with other packaging materials.
With the front panel still removed
1. Plug the chiller’s power cord (not the controller) into 120V wall outlet and check to make
sure that both the fan and compressor come on. Do not leave chiller plugged in for more
than 2 minutes.
2. The temperature sensor for the controller MUST be installed inside the sensor port of
the chillers evaporator housing. Failure to install the sensor into this port may cause an
inaccurate temperature reading and, in the event of low or no water flow, may cause damage
to the chiller. Locate and install the temperature sensor for the controller. Insert sensor
completely into the sensor port. It is not necessary to remove the compression fitting
holding the sensor port in place. Use the supplied piece of cork tape to hold the sensor in
place by wrapping the tape around the entrance to the sensor port. This will isolate the
temperature sensor from ambient heat.

Chiller installation
1. Make sure the chiller is placed on a firm, level surface in a location that has plenty of ventilation
and will not be exposed to salt or saltwater. Do not use an extension cord for the chiller or the
thermostat.
The requirements for ventilation are
a) Back portion: Condenser (radiator) requires at least 10” clearance to allow air into the
chiller.
b) Front portion: Requires at least 15” clearance to allow for proper air flow.
c) Chiller must not be placed in a closed closet or cabinet.
d) The warm air from the chiller must be completely evacuated from the chiller location. A fan may
be necessary to draw warm air away from the chiller. The maximum operating temperature is
95° F.
2. The Prime chiller can be plumbed with either rigid PVC or vinyl tubing connected to an external
or submersible pump (not included). Use ¾” ID (inside diameter) or larger pipe/tubing for
all plumbing connections.
3. The inlet and outlet are located on opposite sides of one another (See diagram below).
Either port can be used as the inlet or outlet depending upon the location of the chiller
and plumbing configuration. The ports will accept 1” male pipe thread (MPT) fittings for
plumbing with rigid PVC. You may also use the enclosed barbed fittings for plumbing with
vinyl tubing. Use Teflon tape for all threaded fittings.
4. It is strongly recommended to use unions and ballvalves connected to the inlet and
outlet for maintenance and servicing.
5. For the most efficient control over the aquarium’s temperature, it is recommended that the
chiller be plumbed so that it is the last component before water returns back to the tank. If
other devices, such as a mechanical filter, precede the chiller, make sure the flow rate going
through the chiller still meets the minimum flow rate requirement.
6. Once you have finished plumbing the chiller it is recommended that you circulate water
through the chiller and plumbing for at least 30 minutes to ensure adequate water flow and
no leaks.
7. Tilt the chiller from the back to allow any trapped air to escape from the evaporator housing.
You may need to do this a few times until all of the air has escaped.

Prime Chiller Temperature Controller
This microprocessor based electronic temperature controller is designed to provide on/off control of
heating and cooling. It is equipped with an easy to read Liquid Crystal Display (LCD) that displays a
constant readout of actual temperature, control settings, relay status and system diagnostics. The simple
keypad allows programming of set point temperature, selectable Fahrenheit/Celsius scale, temperature
differential and cooling/heating mode of operation. Lockout feature prevents tempering from unauthorized
personnel. Controller is housed in water tight Nema type 4X housing rated for outdoor use.

Installation
1. The temperature sensor for the controller MUST be installed inside the sensor port of
the chillers evaporator housing. Failure to install the sensor into this port may cause an
inaccurate temperature reading and, in the event of low or no water flow, may cause damage
to the chiller. Locate and install the temperature sensor for the controller. Insert sensor
completely into the sensor port. It is not necessary to remove the compression fitting holding
the sensor port in place. Use the supplied piece of cork tape to hold the sensor in place by
wrapping the tape around the entrance to the sensor port. This will isolate the temperature
sensor from ambient heat. Chillers must use controllers supplied by Current-USA, Inc. Use
of any other controller will void the chiller warranty.
2. Plug the power cord from the chiller into the female outlet on the temperature controller
and plug the controller’s power cord into a 120V GFCI protected wall outlet. Do NOT use
an extension cord between the chiller and controller, or between the controller and wall
outlet.
3. Set the controller to the desired temperature and differential (see Programming the Controller.)
A differential of 2 degrees (2° F/C) is recommended with many heat load situations to
allow the chiller to completely cycle and prevent damage to the start-up components and
compressor.

maintenance
Maintenance
Your Prime Chiller, if installed correctly, should provide years of service with a minimal
amount of maintenance.
For proper maintenance:
1. Clean the condenser (radiator) fins regularly. Using a vacuum and soft brush attachment,
remove lint, dust and animal fur at least once a month to allow for optimal heat removal and to
prevent the compressor and electrical components from overheating. It is also recommended
once every 3 months to remove the cover and clean the condenser fins on the inside of the
unit where the fan is located. Debris can migrate inside of the unit where it may not be able
to be reached from the outside.
2. Periodically inspect all fittings for leakage. Although most aquarists typically do inspect all
their fittings once in a while, it is important to inspect the fittings attached to the chiller
as leaking water (particularly salt water) can damage the components of the chiller if not
discovered.
3. Periodically flush the evaporator. The refrigerant coils inside the evaporator housing can trap
organic debris as well as become coated with mineral deposits such as calcium (especially
with saltwater reef systems). It is recommended that the chiller be removed from service once
a year and the evaporator flushed with freshwater. In addition, circulating a diluted hard
water stain remover through the evaporator will help remove deposits that can affect the
chiller’s performance. Be sure to rinse well with freshwater and let dry before re-installing
the chiller on your system.
