Installation eco
8 0 0
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 Eco800 is electrically connected. Ensure that it is isolated from electrical supply during
installation and any subsequent service work.
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).
1. Plan the position of the pump
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.
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.

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.
4. Electrical
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.
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.
5. Equipotential bonding
If equipotential bonding is required (refer to local statutes and regulations), 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.

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
Eco800 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.
a) Before removing trap lid, SWITCH OFF POWER SUPPLY to pump.
b) CLOSE SHUT-OFF VALVES on suction and discharge pipes, if present.
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 Eco 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.

during the normal operation and expected life of the pump.
Once per week Once per month
FREQUENCY
CHECK
Inspect trap basket, and empty of any leaves
and other debris. Leaves and other debris
that collects in basket will choke off water
flow through the pump and reduce efficiency
and performance. See below instructions on
cleaning the trap.
Clean area around pump and ensure there
are no leaves or debris which could become
a fire hazard or choke the motor fan.
Check the pump to ensure no water is leaking
from inlet and outlet joints, whilst pump is
operating. If leaks are noticed, clean and grease
the o-rings or replace if necessary.
Check that there are no leaks from under the
pump. If there are, this could be a sign of a
leaking mechanical seal. Call a Pentair Service
Agent immediately, to prevent damage to the
motor.
Check pump and motor for insects and pest
infestations and ensure that motor fins are clean
of dust and dirt. Clean if necessary.
Follow instructions below to clean trap:
1. Switch off power to pump, close valves in suction and discharge, and release all pressure from system before
proceeding.
2. Remove trap cover (turn counter clockwise). If necessary, tap handles gently with a rubber mallet.
3. Remove strainer basket and clean. Ensure all holes in basket are clear, flush basket with water and replace in trap with
large opening at pipe connection port (between ribs provided). If basket is replaced backwards, the cover will not fit on
trap body.
To clean transparent cover, use water and neutral soap only. Do not use solvents.
4. Clean and inspect lid o-ring; reinstall on trap. Clean O-ring groove on trap body and replace cover. To help keep cover
from sticking, tighten hand tight only.

TROUBLESHOOTING GUIDE
SYMPTOM CAUSE REMEDY
Low water pressure, low flow
from pump.
Suction leaks / lost prime.
Low speed setting.
Clogged pipe / strainer /
impeller / filter system.
Pump must be primed; make sure that
the pump casing and strainer are full of
water. Refer priming instructions.
Make sure there are no leaks in suction
piping and ensure all o-rings are present
and clean.
Make sure suctions pipe inlet is well
below the water level to prevent pump
from sucking air.
Suction lift of 3 to 6 metres will reduce
performance. Suction lift of more than 6
metres will prevent pumping and cause
pump to lose prime. In either instance,
move the pump closer (vertically) to water
source. Ensure that the suction pipe
diameter is large enough.
Check speed setting. Refer to speed
selection section of this manual. Reset to
default if necessary.
Ensure trap is not clogged with debris;
clean basket and/or filter.
Make sure that the impeller is not clogged.
