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 for 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 metres however refer to your pumps
data plate for actual achievable pressure.
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 35C degrees.
H. Pumps must be either
a. Supplied by an isolated transformer, or
b. Supplied through a residual current device (RCD) with a rated residual operating current not exceeding
30mA.
OPERATION
1. Switch on power to pump, motor to start.
2. If some flow of water does not establish within on 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.
3. 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.
4. The eCombi EE2 has 2 set speed settings –Low and High. High should be used when backwashing, manually vacuuming
the pool or operating spa jets or some water features such as waterfalls. Low 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.
5. The eCombi EE2 will automatically start on High 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.
6. 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 Astral Pool, or its service agent or a suitably
qualified person.
The eCombi EE2 pump is designed to operate in ambient temperatures of 2°C to 40°C.
Hours of Operation
On low speed your eCombi EE2 pump makes very little noise and is unlikely to be intrusive to you or your neighbours.
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 sanitise your pool.
Greater energy savings occur when operating the pump for longer periods at the low speed instead of operating for shorter
periods at the high 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 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.
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. Other purpose flow rates may include but are not limited to: operating spa jets,
operating water falls or water features, operating a suction pool cleaner.
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.

Some Tips:
The eCombi EE2 will provide around 29,000 litres per hour on high speed, depending on pipework, valves, filter size and other
equipment installed on your pool. On low speed the flow rate is approximately 14,000 litres per hour, therefore, operating
the pump 4 hours per day will provide a 56,000 litre pool one complete turn over. Low speed will use approximately 20% of
the power consumption that high speed will use.
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 HIGH medium speed to achieve full circulation and good surface skimming 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
time on high speed 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.

OPERATION OF CONTROL PANEL
The eCombi EE2 pump incorporates a user panel that allows you to select between low speed and high speed simply by
pressing the desired button. The selected speed will be highlighted by a green LED light above the button.
When plugged into power the pump will automatically start and run on High Speed for 5 minutes. It will then revert to the
speed it was previously set on.
To turn the pump off switch it off at the power point.
USE WITH SUCTION CLEANERS
When connecting a suction cleaner to the eCombi EE2, it is 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 High speed button.
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 Ecombi EE2 Pump.
4. When cleaner is no longer required, disconnect and remove hose/cleaner plate from system. Select the lowest filtration
speed that keeps your pool clean.
5. If replacing or selecting a new cleaner, AstralPool recommend an AstralPool Robot Cleaner which operates 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
the eCombi EE2 pump operates on low speed the water pressure produced is generally insufficient to activate the pressure
switch and control circuit within the heater.
If using a compatible AstralPool Gas Heater you can select the High Speed on your eCombi EE2 pump to ensure the water
pressure switch is activated and the heater obtains enough water flow to operate correctly.

MAINTENANCE
Maintenance Schedule: Your 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.
