Inst.434 Viron XT Pool & Spa Pump V08_17
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.
