Installation Manual
Section 5. Operation
5.1
Normal Operation
The Viron XT Series 2 Pumps has three (3) pre-set
speed settings: Low, Medium and High.
• Low speed is the recommended setting for everyday
pool filtration when a cleaner is not connected.
• Medium speed can be used for gentle spa jet action,
when a suction cleaner is connected to the skimmer or
pool filtration.
• High speed should be used when backwashing,
manually vacuuming the pool, or operating spa jets or
some water features such as waterfalls.
5.2
Starting Up the Pump
CAUTION
Never run the pump without water. Running the
pump “dry” for any length of time can cause severe
damage to both the pump and motor and will void
the warranty.
If this is a new pool installation, make sure all piping
is clear of construction debris and has been properly
pressure tested. The filter should be checked for
proper installation, verifying that all connections and
clamps are secure according to the manufacturer’s
recommendations.
WARNING
To avoid risk of property damage, severe personal
injury or death, verify that all power is turned off
before starting this procedure.
1.
Depending on the location of the pump, do one of the
following:
•
If the pump is located below the water level of the
pool, open the filter pressure release valve to prime
the pump with water.
•
If the pump is located above the water level of the
pool, remove the lid and fill the basket with water
before starting the pump.
2.
Prior to replacing the lid, check for debris around
the lid o-ring seat. Debris around the lid o-ring seat
will cause air to leak into the system and will make it
difficult to prime the pump.
3.
Hand-tighten the lid to make an air tight seal. Do not
use any tools to tighten the lid: hand-tighten only.
Make sure all valves are open and the unions are tight.
Restore power to the pump.
4.
Once all the air has left the filter, close the pressure
release valve.
5.
Press the MENU button for initial programming to
enter overdrive speed. FAST and two (2) rotating
circles will show on the user interface display.
•
Viron XT Series 2 Pump primes 30% faster than
conventional maximum speed.
•
Viron XT Series 2 Pump automatically limits
maximum speed according to the system’s total
dynamic head and power consumption.
•
Once the pump is primed (or fail to prime within
five (5) minutes), the speed will return to the last
speed when in the MANUAL mode.
6.
If the water flow is not available within 1/2-minute,
turn off the power and prime the pump again. After
three (3) attempts at priming, turn off the pump and
check for leaks.
NOTE
If no leaks are evident, a check valve or foot valve is
required to hold water for priming.
7.
If water flow is not adequate after cleaning the lint
basket, turn off the power and check for other issues
such as the check valve, air leaks, faulty seal, cracked
lint pot lid, etc.
8.
The Viron XT Series 2 Pump will automatically start on
PRIME speed for the first five (5) minutes to assist with
priming, which will quickly fill the hair and lint pot
with water.
After five (5) minutes, the speed will return to the last
speed when in the MANUAL mode. Note: See Section
6 for further details on adjusting the Prime speed and
Prime time.
9.
During normal operation, it is recommended that the
Viron XT Series 2 Pump operate on LOW speed for
twelve (12) hours per day. This setting provides the
lowest operating cost with the lowest noise levels.
Should the pool have areas where the water does not
turn over with this setting, increase the speed until the
desired water movement is obtained.

5.3
Pump Lid Removal
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in the
variable-speed pump electrical circuit before starting the
procedure. Failure to comply may cause a shock hazard
resulting in severe personal injury or death.
1.
Make sure that the pump is turned OFF.
2.
Make sure that the switch to the circuit breaker to the
motor is turned OFF.
3.
Make sure all necessary isolation valves are closed to
prevent water from reaching the pump.
4.
Following the markings on the locking ring, turn the
ring counter-clockwise until the ‘START’ markings align
with the ports. See Figures 11.
5.
Carefully remove the lid with locking ring.
