CIRC-3 VARIABLE PEED PUMP IN TALLATION
GENERAL
Your TURBO-TECH CIRC-3 pump has been quality built and engineered to give maximum energy efficiency under
normal spa water pumping conditions. Consult the manufacturer for any other applications.
LOCATION OF PUMP
For the best pump performance, locate the system as close to the water source as possible, preferably in a dry
position lower than the spa water level. Make sure the pump has adequate ventilation, is well fixed at the base plate
provided and is not accessible to persons whilst in the spa. Provide adequate access around the pump for inspection
and maintenance.
PLUMBING CONNECTION
Fit the pump to your plumbing scheme using the 40mm (1.5”) Quick Connect Unions provided. Ensure Union
O’Rings are clean. Lube with silicon based lubes only (DO NOT USE PETROLEUM BASED LUBRICANTS). Hand
tighten Unions only. Do not over tighten.
TARTING & PRIMING PUMP
Do not run unit dry. Always be certain that the pump casing is filled with water before starting the unit. Allow a
reasonable amount of time for priming. If the pump will not start or will not prime, see troubleshooting section in this
manual.

MAINTENANCE
Keep motor clean. Ensure that louvered openings and cooling fins are free from dust and debris to avoid
overheating. Over a period of time the shaft seals may become damaged or worn and must be replaced.
CIRC-3 BRIDGE CONTROL IN TALLATION
GENERAL
Your CIRC-3 Bridge Control is engineered to interface your variable speed pump with your spa control system. The
CIRC-3 Bridge receives signals from the spa control system and from these signals interprets the various modes the
spa control system is in (i.e. filtration, heating, turbo jet action). The bridge Control then sends instructions to the
Circ-3 variable speed motor to select the most appropriate, energy efficient speed for the motor to run at for that
particular mode.
LOCATION OF BRIDGE CONTROL
The CIRC-3 Bridge Control should be located and fixed in a convenient position between the CIRC-3 variable speed
pump and the spa control system. Make sure the Bridge Control is not accessible to persons whilst in the spa.
Provide adequate access around the Bridge Control for inspection and maintenance.
ELECTRICAL CONNECTION
The CIRC-3 Bridge Control is provided with all the cables necessary to connect between the variable speed pump
and the spa control system. The following diagram illustrates the various cables and connections necessary.
TARTING & OPERATING CIRC-3 Y TEM
Circ-3 incorporates sophisticated electronics to control and deliver the various quiet, energy efficient features
designed into this product. Once all the cable connections have been made and the pump primed, turn on your spa
control system and bridge control via the spa mains isolating switch. Set your spa control system as per the spa
control manufacturer’s recommendations incorporating your personal preferences in regards to time, filtration cycles,
desired water temperature, equipment fitted etc. Please note, for the “Pump 1” outlet, you need to set this in the
“2 Speed Pump” configuration as per the spa control system manufacturer’s instructions.

www.csnglobal.com.au
The CIRC-3 Bridge will now start its boot up process. As part of the boot up process when Turbo-Tech Circ-3 is
started from a power off status, a full systems check automatically occurs. This process may take up to 5 seconds to
complete after the initial power up. The variable speed motor will then start. The CIRC-3 Bridge will determine what
mode the spa control is in and select the appropriate speed for the variable speed motor to run at. A manual input by
the spa user to the “Pump 1” button on the spa control keypad for high speed (Turbo Jet action) will cause the Bridge
Control to tell the motor to run at full speed. A second input will cause it to go back to either a heating or filtration
mode speed.
IMPORTANT NOTE
After the spa control system calls for Pump 1 to turn off completely, the Bridge Control
must be given a chance to reboot after a manual input for the pump to re start is made.
Therefore under these conditions, please allow 5 seconds after pressing
the Pump 1 button for the motor to start. Continuous inputs to the Pump 1
button within the 5 second delay will disrupt the boot up and delay or confuse the start
up process. If this occurs, refrain from any further inputs for one to two minutes, and
then start the process again, this time allowing the system 5 seconds to start.
TROUBLE HOOTING
MOTOR WILL NOT TART:
1. Check circuit breaker.
2. Check cabling is correctly fitted as per wiring instruction.
3. Check for loose connections.
4. Check spa control system is correctly configured with the “Pump 1” outlet set to “2 Speed”.
5. Check for any error symbols on the spa control system and follow manufacturer’s recommendations
for any of those error messages.
MOTOR OVERHEATING AND/OR HUTTING DOWN:
1. Check for incorrect cabling and/or loose connections.
2. Make sure motor gets adequate ventilation and is free from debris.
3. Make sure ambient temperature where motor is located is not exceeding 50 degrees C.
MOTOR MAKING HUMMING NOI E BUT WILL NOT TART:
1. Check for debris causing the pump impeller to jam.
NOI E:
1. Check plumbing vibration.
2. Check for cavitation due to air leaks, obstruction, undersized suction or dirty filter element.
3. Check for debris in the pump wet section.
PUMP WILL NOT PRIME:
1. Make sure pump is installed at the proper level and the plumbing lines have been correctly installed to
allow water to freely enter the pump.
2. Open Air Control valves to release any possible air lock.
3. Loosen off pump discharge union SLIGHTLY whilst motor is running to bleed off any air locked in the
pump wet section. Retighten once water appears.
4. Make sure all suction and discharge lines are clear and unobstructed and all valves are open.
5. Check for air leaks in the suction line.
LOW WATER FLOW AT HIGH PEED:
1. Check for clogged plumbing lines or dirty filter element.
2. Check for worn or damaged impeller.
3. Check to ensure motor is transitioning correctly between its 3 speed options.
WATER LEAK
1. Check for contamination or damage to the shaft rotary seal. Replace if necessary.
2. Check union compression fittings; make sure they are properly aligned and secure. Hand tighten
only. Do not use tools.
3. Make sure O’Rings are properly seated, free from contamination and not damaged.

BRIDGE CONTROL DOE NOT TRAN ITION PEED CORRECTLY OR A REQUIRED:
1. Check that cabling is installed correctly in accordance with the wiring diagram.
2. Check to ensure all connections are not loose.
3. Make sure Spa Control System is configured for a “2 Speed Pump” on the “Pump 1” outlet.
4. Make sure spa control system is correctly programmed and configured for filtration maintenance and
heating cycles.
5. Check for a clean power supply to the Bridge Control.
6. Check circuit breakers.
7. Make sure the pump is given 5 seconds to start from an “OFF” status before making further inputs to
the “Pump 1” button on the spa control keypad. Further inputs made within the 5 second boot up
period WILL disrupt the start up and transitioning process. If this happens, make no further inputs for
1 to 2 minutes to allow the system to stabilise, then press the “Pump 1” button once and wait 5
seconds for motor to start before making any further inputs.
