Installation Instructions
Location
The pump should be located as close to the water as practicable and mounted on a firm base in a well
drained position, high enough to prevent any flooding. It is the installer’s/owners responsibility to locate
the pump so that it can be accessed for service and maintenance. The rear fan shroud should be installed
at a minimum distance of 100 mm away from any walls or obstructions. This is to allow adequate air flow
from the fan to cool the motor. Overheating due to a lack of cooling voids warranty.
Weather Protection
It is recommended that the pump be protected from the weather.
Enclosures should be ventilated to allow a free flow of air for the fan cooled motor.
Power Connection
THERALUX pool and spa pumps are suitable for connection to a nominal 240-volt 50Hz power supply.
The motor is equipped with a flex and 3-pin plug. If a power outlet is not available within 2 meters of the
pump, a 3-pin power point in a safe, dry place may need to be provided by an electrician.
Note:
 Pumps must be either
o Supplied by an isolating transformer, or
o Supplied through a residual current device (RCD) with a rated residual operating current
not exceeding 30mA.
 Extension cords are unsafe around pools and must be avoided.
 If the supply cord of this product is damaged the dealer or manufacturer must replace it, with
genuine THERALUX pool and spa pump spares.
 Water temperature is not to exceed 45 degrees
1.25hp @ 670
1.75hp @ 700

Pipe Connection
A barrel union is provided for connecting to the piping from the pool.
The pumps are designed to accept the following PVC Pipes:
 Inlet PVC Position 40mm pipe ID or 50mm fitting ID PVC pressure pipe fittings
 Outlet PVC Position 40mm pipe ID or 50mm fitting ID PVC pressure pipe fittings
The use of pipe with a smaller ID than those specified above is not recommended and may cause damage
to the pump voiding warranty.
A straight length of pipe measuring no less than 300mm should be installed in front of the inlet of the
pump allowing quieter and smoother operation.
Suction piping should be free from all air leaks and any humps and hollows, which may cause suction
difficulties.
The outlet piping from the pump should be connected to the inlet connection on the swimming pool filter
(at the filter valve).
For pump installations above water level, it generally requires a check valve in the suction line.
Do not use type ‘P’ (green) plumber’s glue on the barrel unions as this may cause damage to the material
used.
Always install pump for maintenance and service accessibility.
USAGE WARNING
 The TVS Pro is manufactured with technological advances including PCB’s and microchips. It is
necessary to turn power off completely for 10 seconds prior to turning pump back on again
 Some brands of older style chlorinators may release a small amount of power to the TVS
PROeven whilst it seems turned off. It this occurs the TVS PROmay not reset correctly until
power is completely disconnected.
 In some cases, chlorinator manufacturers may be able to modify internal components so as to
work in with the V3PRO. If not a suitable chlorinator may be required.
 Theralux’s chlorinator completely disconnects power to the pump when the pump is in off mode.

OPERATION
Starting the Pump
To operate efficiently and to prevent damage to the pump there must be a free flow of water to and from
the pump. Before starting ensure that:
 All pipe work is correctly sealed.
 Barrel unions on the inlet and outlet are hand tightened and the pipework
is installed square to the pump.
 The pool/spa water level is at the correct height.
 That all appropriate valves are open and there is nothing preventing the
flow of water through the system.
1. First prime the pump by removing the strainer basket lid and filling the strainer
basket area with water. Replace the lid, ensuring that it seals on the large o-ring.
2. Connect to the power supply and switch on.
3. Allow the pump to run, so that any air trapped in the pipe work and pump may be
expelled.
4. If prime is not established within approximately two minutes, as evidenced by a
strong flow of water from the outlet, switch off the pump for 10 secs and repeat the
procedure. Continued evidence of air under the hair and lint pot lid indicates an air
leak in the suction piping work, which should be rectified to avoid pump damage.
5. If water flow through the pump is continuously tedious to obtain at start-up after
cleaning the lint basket, then an examination of the system to establish a reason
and correct the cause. (ie. Check valve, air leaks, faulty seal/s, crack lid.

THERALUX’S RECOMMENDATION
 During day-to-day operation we recommend to run the TVS PRO on “eco” for 8-10 hours. This
will achieve the lowest noise and lowest operating costs whilst maintaining filtration
effectiveness.
 In some cases (larger pools, warmer climates and increase bather loads you may have to increase
the speed setting or operating duration. This will still provide you with significant savings.
Limits
Water temperature Max 45oC
Ambient Temperature Max 55oC
DBa @ 1 meter 62
Water Quality
Maintaining balanced water chemistry is important to the life of your pool pump.
This pump is designed to be used with Pool & Spa water, balanced in accordance with Langlier Saturation
Index, with a pH level of between 7.2 and 7.8 and is regularly treated with a chlorine sanitizing agent with
the level not exceeding recommended chlorine levels.
Please consult your local pool shop regularly to have your water tested.
Emptying the hair and lint pot
The hair and lint pot strainer basket should be inspected frequently through the transparent lid and
emptied when a build up of rubbish is evident.
Follow the directions below.
1. Switch off pump.
2. Unscrew the hair and lint pot strainer basket lid anti-clockwise and remove.
3. Remove the hair and lint pot strainer basket by lifting upwards from its housing.
4. Empty the trapped refuse from the basket. Hose out with water if necessary.
5. Check the hair and lint pot strainer basket for cracks, replace the strainer basket in the pump if
OK.
6. Replace the lid and ensure that it seals on the large rubber o-ring. Firm hand tightness only is
required. The o-ring & thread can be lubricated with silicone grease.
HOW TO CONNECT TO SUCTION CLEANERS
 It is important that the TVS PRO is fully primed when connected to a suction cleaner.
 Switch pump to “high” setting for 2 minutes if pump is currently switched on, or allow for initial 3
minute prime.
 Connect cleaner hose to skimmer plate only after air has been purged from top of hair and lint
pot
 Select speed (usually “med”) at which the cleaner will travel to all areas of the pool
 Disconnect cleaner and remove from pool once it is cleaned. Change setting back (usually “eco”)
to your daily filtration requirements.

TROUBLE SHOOTING
If the pump does not operate, one of the following conditions may apply:
a. The power is not connected. For 240 volts only.
b. Check the power point by plugging in a portable appliance to ensure power is available.
c. Check fuses and the main power supply switch
d. Automatic overload is tripped. The pump has an in-built thermal overload, which will re-
set automatically after the motor has cooled following an overheating period.
Determine the cause of the overload tripping and rectify.
e. Pump needs to be disconnected for 10 secs and reconnected
f. Blockage is preventing the pump from rotating.
g. If plugged into chlorinator, disconnect and reconnect directly to power after 10 secs. If
it then works, please check your chlorinator manual.
h. Motor is burnt out - burning smell is evident. Replacement is required.
i. If you are unable to resolve any installation or operation difficulties with your
THERALUX pool and spa pump, contact the supplier from whom the pump was
purchased or you’re nearest Authorized THERALUX pool and spa pump Pool Equipment
Service Centre. If any further assistance is required, contact the THERALUX Customer
Service Centre at the address indicated in this manual.
If the pump runs but there is no water flow or water flow is reduced, the following
condition may apply:
1. The filter requires backwashing or it is blocked.
2. Disconnect the suction cleaner
3. Check the skimmer box for blockage.
4. The pump is not primed, increase speed. If this doesn’t work within 1 minute turn off.
(See ‘Starting the pump’)
5. There are air leaks in the suction piping. Check all piping and eliminate leaks, also check
for a loose strainer basket lid. Air bubbles in the water flowing back to the pool would
indicate a leak in the suction to the pump allowing air to infiltrate the pipe work.
6. The pump is not able to get water from the pool. Check that the valves to the pump are
fully open and that the pool water level is up to the skimmer box.
7. A leaking pump seal may also prevent operating. Evidence of this would be water on the
ground under the pump.
8. Blockage in the piping or pump. Remove the hair and lint pot strainer basket and check
for any blockage to the pump impeller entry.
9. You may require a check valve installed.
Removal of the Pump from Pipe work
To remove the pump, follow these instructions:
1. Switch off the power and remove the plug from the power source.
2. Close the water valves on the pool return and the pump inlet pipe work.
3. Remove the discharge & suction barrel unions taking care not to lose the o-rings.
4. Move the pipe work with the barrel unions attached until the pump can be moved
clear.
NOTES:
 If the pump is hard wired, a qualified electrician should remove the wiring.

Page 13 of 15
 Barrel unions need to be hand tightened. No sealant, glues or silicones are required.
 When making any enquiries about your THERALUX pool and spa pump be certain to quote the
model number from the nameplate located on motor.
NOTES: (cont)
 Never run pump dry. Running the pump with no water may damage the mechanical seals,
causing leakage and flooding. Dry running damage and associated damage is not covered under
warranty.
 Failure to undertake regular maintenance may cause damage not covered by warranty.
 The pump is not intended for use by young children or infirm persons without supervision.
Ensure that young children are supervised at all times to ensure that they do not play with the
pump.
