WhisperFlo VS 800 Owner’s Manual
INSTALLATION
The pump must be installed and serviced by a suitably qualified person in order
to avoid hazard. Incorrectly installed or tested equipment may fail, causing
severe injury or property damage.
These instructions are a guide only. Should you the installer or owner of the
product be unfamiliar with the correct installation or operation of this product
you should contact a suitably qualified person for advice.
Do not connect system to high pressure or mains water system.
This pump is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the pump.
The WhisperFlo VS 800 is electrically connected. Ensure that it is isolated from
electrical supply during installation and any subsequent service work.
1. Plan the position of the pump
For best performance, allow pump suction inlet height to be as far below
water level as possible and allow the use of short, direct suction pipe with
minimum bends (to reduce friction losses).
a. Have enough ventilation to keep ambient temperature below the motor’s rated ambient
temperature whenever the pump is running. If installed in an enclosure/pump house,
the enclosure must have adequate ventilation (200sq.cm min, inlet & outlet) and air
circulation Allow 200mm to keep rear of motor clear.
b. Have adequate floor drainage to prevent flooding and be protected from excess
moisture.
c. Be solid, level, rigid and vibration free.
d. To reduce vibration and pipe stress, bolt pump to mount. Fixing holes accept 12mm
fasteners.
e. Be within 2m of a power outlet for electrical connection (refer to AS/NZS 3000 for rules
regarding connection of electrical equipment in pool zones).
f. Allow adequate access for servicing pump and piping.

8WhisperFlo VS 800 Owner’s Manual
3. Pool Outlets
a. The pump suction system must provide protection against hazard
of suction entrapment or hair entrapment/entanglement. The
pool outlet piping must be in accordance with the latest AS1926.3
standard.
b. Suction outlet covers and skimmers must have been tested and
found to comply with the latest AS1926.3 standard or ASME/ANSI
specification for Suction Fittings.
2. Piping
For best performance, allow pump suction inlet height to be as far below
water level as possible and allow the use of short, direct suction pipe with
minimum bends (to reduce friction losses).
a. Use only Australian Standard PVC pressure pipe. For best performance use at least
50mm diameter pipe for all connections to the pump. Never use a suction pipe smaller
than pump suction connections (50mm) and use larger pipe for long suction distances.
b. To avoid stress on the pump, support both suction and discharge pipes independently.
Place these supports as close to the pump as possible.
c. To avoid a strain left by a gap at the last connection, start all piping at the pump and run
pipe away from the pump.
INSTALLATION

WhisperFlo VS 800 Owner’s Manual
INSTALLATION
Do not use extension leads as they are unsafe in and around the Pool Zone.
Hazardous voltage. Can shock, burn or cause death.
To avoid dangerous or fatal electrical shock, turn OFF power to pump and
remove plug from outlet before working on electrical connections.
4. Electrical
5. Equipotential bonding
If equipotential bonding is required, connect all metal parts of the swimming pool or spa
structure and to all electrical equipment, metal conduit, and metal piping in accordance with
the wiring rules. Run a wire from the equipotential bonding terminal on the pump (bottom,
left motor bolt with serrated washer) to the pool bonding structure.
a. Electrical installation shall be in accordance with the national wiring rules (AS/NZS
3000) taking into account its ratings (Class I, IPX5). The pump is supplied with a standard
Australian 10 amp plug and 2 metres of cord. Select the correct Pool Zone for installation.
b. An RCD with maximum rated residual current of 30mA is required for the power supply
to the pump. Additionally, if a suitable socket outlet is not available a weatherproof
socket must be installed by an electrician in a suitable location. RCD tripping indicates an
electrical problem. If RCD trips and will not reset have a qualified electrician inspect and
repair electrical system.
c. Incorrect voltage can cause fire or seriously damage pump and voids warranty.
d. Voltage at pump must not be more than 6% above or 10% below motor nameplate rated
voltage or pump may overheat, causing overload tripping and reduced component life. If
voltage is less than 90% or more than 106% of rated voltage when pump is running at full
load, consult the power company.

OPERATION
1. Priming the pump
NEVER run pump dry. Running pump dry may damage seals, causing leakage and
flooding. Fill pump with water before starting motor.
Freezing conditions will damage the unit, as water expands as it freezes. Ensure that
the WhisperFlo VS 800 is located so that it is not prone to freezing, or ensure that the
product is disconnected and dried of water during cold conditions.
Trapped air in system can cause explosion. Ensure all air is out of the system before
operating or testing equipment.
Fire and burn hazard. Modern motors run at high temperatures. To reduce the risk of
fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. To
avoid burns when handling the motor, let it cool for at least 20 minutes before trying to
work on it.
Small children using pool must ALWAYS have close adult supervision.
Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use
or operate pump, pool/spas if a suction outlet cover is missing, broken, or loose. Follow
the guidelines below for a pump installation which minimises risk to users of pool and
spas.
NEVER tighten or loosen trap lid while pump is operating.
It is not necessary to lubricate the
o-ring. The original equipment
O-ring contains a permanent
internal lubricant.
c. Remove the trap lid (turn anti-clockwise).
d. Fill trap tank with water.
e. Check the lid o-ring and sealing surface, ensure there is no dust or debris on either, and replace
the lid (turn clockwise to tighten by hand only - no wrenches!).
f. Open the shut-off valves on the suction and discharge pipes, if present.
g. Release all air from filter, pump and piping system (refer filter owner’s manual). In a flooded
suction system (water source higher than pump), pump will prime itself when suction and
discharge valves are opened and air is released.
h. Switch on power to the pump to start.
i. Pump should start to prime now. Priming time will depend on vertical height of suction lift and
horizontal length of suction piping but is generally between 30 seconds to 3 minutes under
normal installation conditions.
j. The WhisperFlo VS 800 will start slowly but ramp up to high speed for the first 2 minutes to assist
priming. It will then switch to the selected speed.
*Should the pump not prime, ensure that all valves are open, lint trap is clear of debris and suctions and suction
pipe end is submersed in water, and that there are no leaks in suction pipe. See troubleshooting guide.
a. Before removing trap lid, SWITCH OFF
POWER SUPPLY to pump.
b. CLOSE SHUT-OFF VALVES on suction and
discharge pipes, if present.
