DIMENSIONS
INSTALLATION
This appliance must be installed by a trained pool professional service technician. When installing the appliance, ensure all
parts are installed in the correct zone in accordance with the wiring rules. In particular refer to AS/NZS 3000 (Australia) and
EN 60364 (EU).
A. Plan position of pump so that it will be:
1. Free of water flooding, such as in a sump, garden hollow, ditch or at bottom of bank with run off.
2. On a stable base so that:
a) The pump is not left suspended by its fittings, causing a leak or failure with loss of water.
b) Movement through vibration is restricted
c) No strain is put on attaching pipe or other expensive equipment
3. Accessible for maintenance and easily removed for service.
4. Breathing space. Pump should not be crowded which will prevent cooling airflow from fan. Overheating due
to lack of cooling voids warranty.
5. Within reach of power point without extension/plugs liable to corrosion, shorting, etc.
6. At a minimum height of suction lift of water from pool surface to pump inlet.
B. For best pump performance keep suction pipe length as short as possible with minimum number of bends and use
50mm high pressure PVC suction and return pipe. All equipment such as filters, heaters, chlorinators must have a
minimum of 50mm connections.
C. Secure the barrel unions supplied into the attaching pipe work, using approved priming fluid and solvent cement as
normal practice, coating both surfaces. NOTE: Always wear protective gloves when handling and using glue and
priming fluid. Ensure no excess adhesive runs into the union proper affecting the sealing or removal abilities.
Allow 24 hours to dry before starting pump. Do not use “green” glue on barrel unions. This can cause damage to
the ABS material used to manufacture the unions.
D. Install isolation valves before the pump section and after equipment, if the pump is below the water level of the
pool.
E. For pump installations 500mm above water level, it generally requires a foot valve at the pool or check valve in the
suction line. Suction lines must be installed below water level until just in front of pump location and vertical riser
used to reach pump inlet. AstralPool pumps are rated to a maximum head of 25 meters however refer to your
pumps data plate for actual achievable pressure

Inst.434 Viron XT Pool & Spa Pump V08_17
4
F. All pumps will operate quieter and perform more efficiently if a straight length of 450mm pipe is plumbed
horizontally into the front of the pump.
G. Water temperature not to exceed 45 degrees
H. Pumps must be either
- supplied by an isolating transformer, or
- supplied through a residual current device (RCD) with a rated residual operating current not exceeding 30mA.
Warning: Viron pumps include PCB's and microchips. It is necessary to turn power off completely for 10 seconds
before turning pump back on again. Some brands on chlorinators may bleed a small amount of power into the Viron
Pump even when the pump off mode is selected. If this occurs, the Viron Pump may not reset correctly and may not
start until power is disconnected completely. In some cases, the manufacturer of these chlorinators may be able to
remove or change a capacitor which will completely disconnect power to the pump when turned off. If not, a suitable
chlorinator may be required to be purchased. Astral Pool chlorinators completely disconnect power to the pump when
the pump off mode is selected.
OPERATION
1. Prime pump if hair and lint pot is dry as follows –Close off valve on suction line if present. Remove lint pot lid. Fill
lint pot and chamber with water. Replace and secure lint pot lid and seal.
2. Open all valves, allowing water to flow through pump.
3. Switch on power to pump, motor to start.
4. For initial priming of the pump, press the “Menu” button and “FAST” will be displayed on the screen. The pump will
then run at “overdrive” speed and the display will show 2 rotating circles. The pump will then prime 30% faster than
at the conventional maximum speed. During this priming period the pump will automatically limit its maximum
speed according to the systems total dynamic head and power consumption. Once the pump has primed (or if it
fails to prime within 5 minutes) the speed will drop to the speed that it last ran in “Manual” mode.
5. If some flow of water does not establish within half minute, switch off and prime pump again. If pump does not
prime within 3 attempts, check all suction connections for sealing. If these are satisfactory, a check or foot valve is
required to hold water for prime.
6. If the water flow through pump is always 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 is recommended. Eg. Check valve, air leaks,
faulty seal, cracked lint pot lid, etc.
7. The Viron XT has 3 factory pre-set speed settings –Low, Medium and High. High should be used when
backwashing, manually vacuuming the pool or operating spa jets or some water features such as waterfalls.
Medium speed can be used for gentle spa jet action, when suction cleaner is connected to the skimmer or filtration
for the pool. Low is the recommended setting for everyday filtration of your pool when a cleaner is not connected.
8. In High speed, increasing the speed beyond the normal high speed enters “Overdrive” mode. When this function
is selected the motor will attempt to run at the maximum power consumption it is capable of and when there is
significant friction or total dynamic head in the system, the pump will produce more flow and pressure. The
overdrive mode may be particularly useful when operating spa jets, in floor cleaning systems or other water
features.
9. The Viron XT will automatically start on PRIME speed for the first 5 minutes to assist in priming and substantially
fill the hair and lint pot with water. After 5 minutes the pump will revert to the last speed it was set at before it
was turned off. (See “Operation of Control Panel” section below on how to adjust the Prime speed and prime time)
10. During normal operation, it is recommended that the pump be operated on Low for 12 hours per day. This will
achieve the lowest operating costs with the lowest noise level. Should your pool have areas where water is not
turning over when pump is on Low, increase the speed setting.
Notes: The appliance is not intended for use by person including young children or infirm persons with reduced physical,
sensory or mental capabilities, or lack of experience or knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Please ensure that young children are supervised to ensure that they do not play with the pump.
To avoid a safety hazard, the supply cord if damaged, must only be replaced by AstralPool, or its service agent or a suitably
qualified person.
Hours of Operation
On low speed your Viron pump makes very little noise and is unlikely to be intrusive to you or your Neighbor’s. Generally,
your pool filter pump should operate for a minimum of 8 hours a day to provide sufficient skimming (thereby reducing the
amount of debris that falls to the bottom of the pool) and to allow the chlorinator to provide sufficient chlorine to sanitize
your pool.
Greater energy savings occur when to operating the pump for longer periods at the lowest speed instead of operating
for shorter periods at a higher speed.

SELECTION OF APPROPRIATE SPEEDS
General Rules:
The total volume of water in your pool should be turned over at least once a day.
If operating for longer periods of time, you may be able to turn the output of your salt chlorinator to a lower level.
Check your chlorine level frequently to ensure you do not over or under chlorinate your swimming pool.
Low Speed is factory pre set and is the recommended setting for your daily filtration flow rate –enough to gentle
turn the water over once per day and circulate the water completely around your pool. However, it is essential that
your professional pool installer adjust your low speed so that your chlorinator cell remains full or near full of water
during operation and that your skimmer weir door is creating sufficient surface tension to skim leaves from your
pool. Other factors for adjusting low speed may include satisfactory operation of a suction cleaner or increased
flow rate to circulate water to “dead” spots in the swimming pool.
Medium Speed is generally set up as your special purpose flow rate. For example, an In floor cleaning system will
require higher pressures and flow rates to operate and medium speed can be set up to operate the In floor cleaning
system. Other special purpose flow rates may include but are not limited to: operating spa jets, operating water
falls or water features, operating a suction pool cleaner.
High Speed is generally set up to backwash your sand filter. As a rule of thumb, this speed should be set so that
the gauge on your filter is approximately 70kPa to 100 kPa in pressure but this will depend on the size of your filter,
and the size and length of the backwash pipe line.
Overdrive mode can be used to drive in floor cleaning systems, obtain extra pressure when spa jets are selected or
for additional vacuum suction when cleaning the pool.
In warmer weather, or when the pool is used a lot, your pump should operate for 12 hours a day or more. Check your
chlorine levels and visually inspect your water to ensure that (a) you have adequate chlorine and (b) the water in your pool
looks clear and inviting. If you have any doubts, take a sample of water to your local pool shop for a water analysis.
Examples of Speed Selection during operation and use of your Viron P280 or P300 XT Pump:
Function
Speed
Vacuuming Pool or Spa
High Speed or Overdrive
Operating Spa Jets
High Speed or Overdrive
Operating Waterfall or Water Feature
Medium Speed or High Speed, depending on effect
required
Cleaning up pool with Cloudy Water
Up to 24 hours on High Speed or overdrive mode
General Filtration
Low Speed (8 hours in winter, 8 to 12 hours in summer)
Some Tips:
The XT P320 will provide around 15,000 to 18,000 liters per hour on high speed, depending on pipework, valves, filter size
and other equipment installed on your pool. On low speed the factory preset flow rate is approximately 7,500 liters per
hour. Low speed will use approximately 10% of the power consumption that high speed will use. Therefore, operating
the pump 8 hours per day will provide a 60,000 liter pool one complete turn over.
The XT P520 pump will provide around 36,000 liters per hour on high speed, depending on pipe work and the Factory preset
low speed at 1125 RPM will provide around 12,000 liters per minute. This is sufficient to turn a 96,000 liter pool over once
per day.
As a guide, low speed should achieve a visible skimming of the surface of the pool through your skimmer box. When
connected to an AstralPool compatible salt chlorinator, Viron Connect Touch Screen Control System, we recommend that
for one hour a day the filtration period is operated on at least medium speed to achieve full circulation and good surface
skimmer of the pool. The balance of the filtration cycle can then be set on low speed.
However, should your pool water develop cloudiness or your pool surface exhibit algae growth you may need to increase
the low speed of your pump to ensure adequate circulation of water and chlorine to all parts of your pool.
It is important to check your chlorine levels, pH and other parameters to ensure your water quality is correct before
adjusting the speed of your pump. We recommend these checks are carried out by your professional pool shop or service
technician.

USE WITH SUCTION CLEANERS
When connecting a suction cleaner to the Viron XT pump, it essential that full prime is achieved on the pump prior to
connecting the cleaner hose. During operation at low speeds, the pump may only operate with partial prime in the hair and
lint pot chamber.
To operate a suction cleaner on your pump;
1. Choose the speed button (low, medium or high) on which the pump will operate when the suction cleaner is
connected.
2. Allow pump to operate for a minimum of 2 minutes to allow a full prime to be achieved.
3. Connect cleaner plate and hose to skimmer/wall suction only after all air has been purged from the top of the hair
and lint pot of your Viron Pump.
4. Adjust speed (with increase or decrease buttons) at which the cleaner will travel to all areas of the pool. Factory set
medium speed will usually operate all suction cleaner types in most pools. If using the Low Speed setting, it will
usually be necessary to increase the low speed to ensure the suction cleaner operates reliably.
5. When cleaner is no longer required, disconnect and remove hose/cleaner plate from system. Select the lowest
filtration speed that keeps your pool clean.
6. If replacing or selecting a new cleaner, AstralPool recommend our Robotic Range of Cleaners which operate
independently from the filter pump and allows the pump to operate at a speed which offers the maximum energy
(and cost) savings.

USE WITH ASTRALPOOL GAS HEATERS
Gas heaters (and electric heat pumps) generally rely on a water pressure switch to activate the heater control circuit. When
a variable speed pump operates on low speed the water pressure produced in generally insufficient to activate the pressure
switch and control circuit within the heater.
If using a compatible AstralPool Gas Heater you can automatically increase the speed of your Viron XT pump to ensure the
water pressure switch is activated and the heater obtains enough water flow to operate correctly.
A RJ12 (6 wire flat cable) specifically wired and obtained from AstralPool will connect your pump and heater. Refer to
Heater Instruction Manual for data cable connection details.

MAINTENANCE
Maintenance Schedule: You new product incorporates moving parts and withstands high velocity water with
chemicals in it. Some of these parts will wear in the normal course of use and require regular checks and
maintenance. Performing these checks and maintenance will identify parts that have worn and require
repair/replacement before further serious damage is sustained. A small amount of regular care and attention to your
pool equipment will help ensure long life and trouble free performance.
To protect against extremes of temperature, your unit is vented to allow expensive electronics to
cool. Ants and some insects are often attracted to the warmer, dry environment inside the enclosure. We
recommend that, with power turned off, you spray a surface insecticide on the surfaces surrounding the
control to prevent ant and insect ingress. Repeat every three months or as necessary.
