For information
The Breaktank of SEM water treatment B.V.is a universal breaktank that is specially designed for the
supplementation (adding fresh water) of swimming pools. This break tank ensures the necessary
interruption between (drinking) water and swimming pool water. Under no circumstances can water
flow from the pool back into the water supply network, not even when the pressure on the grid
ceases. The SEM Breaktank meets the following standards:
EN1717
Backflow, siphoning and counter pressure are the greatest risks for the quality of drinking water. The
new European standard EN1717 is set up to prevent contaminated water entering the distribution
network of drinking water.
EN1377
A free outlet type "AB" provides a vertical and permanent interruption between the lowest point of
the feed opening and the critical level. The overflow must be non-circular and must be able to
discharge the maximum inlet flow rate under error conditions at positive pressure. Backflow of waste
water (sewage water) into the drinking water network is therefore also excluded

BREAKTANK HA N D B O O K
06/2015 V4.0 3
The SEM Breaktank can be used for the supplementation of a pool. By default, the SEM break tank is
equipped with a universal level control which can measure 1 level. A float switch is supplied to
measure the level in the skimmer or measuring tube. The lift pump has a capacity of 5 to 45 l / min at
11 to 28 m and is protected against dry running. The capacity of the break tank is about 0.8 m³ / hour
with the built-in mechanical float to fill the tank. Optionally, a solenoid valve is available which
increases the filling capacity to 1.5 m³ / hour.
The SEM Breaktank is supplied as standard with a mechanical float to fill the tank and the capacity
is 0.8m³ / hour. See attachment accessories and parts.
This manual contains all information to commission and maintain a SEM Breaktank.
Because the maximum make-up capacity depends on the connection size of the water pipe and the
required head, there may be differences between the capacities mentioned in this manual and the
capacity in your situation.

1. Introduction
The SEM Breaktank has been developed for refilling fresh water (supplementation) in a swimming
pool. The water level of the pool is measured with a level switch in eg the buffer, skimmer or level
pipe. If the level is too low, the pump will start and fresh water will be added. The construction of the
Breaktank is such that swimming pool water can never flow back into the pipeline network
(mandatory by the water company). The water supply network must never be operated by a closed
system connected to the pool. This must always be done by means of an open connection.
Specifications of the Breaktank:
• Complete interruption between pool and tap water according to European standard;
• Built-in level control for 1 pool.
• Switch-on delay 15 sec. and switch-off delay of 10 sec. for the level control. Both are adjustable.
This prevents oscillation of the delivery pump due to wave action in the pool.
• Clear display shows status (Run, Standby, Error);
• Simple menu structure (service and setup menu) with LED display and 3 push buttons;
• High Impact Polystyrene (HIPS) reservoir with a capacity of 15 liters;
• Level measurement of the reservoir by means of a pressure sensor. Level is readable in
millimeters in service menu.
• Mechanical float ½ "(approx. 0.8 m³ / hour) or solenoid valve ½" to fill the reservoir (approx. 1.5
m³ / hour).
• Low level protection to protect the feed pump against dry running.
• The self-priming feed pump (0.37kW) has a capacity of 5-45 l / min
 with a head from 10 to 28m (with a counter pressure of 1 bar approx. 2.5 m³ / hour). The pump
is equipped with a non-return valve and pressure gauge. Pump is switched with an electronic
relay,
 so no danger of sparking or sticking contacts.
• Print is equipped with a relay that switches on water demand. External systems can be
connected to this (max 3A / 230V).
• Glass fuse for electronics (250V / 160mA T) and for pump (250V / 3A T)
• Does not overflow circular, 40x140mm;
• Overflow connection ¾ "F;
• Empty connection with plug ½ ".
• Filling connection 1/2 "F PVC;
• Screw connection for all cabling with removable plugs.
• The Breaktank may only be used for cold water applications, maximum water
temperature 20 ° c.

2. Control
The Breaktank works completely automatically. Once in operation, the make-up can only be stopped
by shutting down the supply tap if necessary, or by switching off the supply voltage. Of course, the
float switch placed in the pool can also be "manually" influenced by placing it higher or lower relative
to the water level. This will shift the switching point and will eventually change the level of the bath.
The level control is equipped with a switch-on and switch-off delay so that the feed pump can never
"shuttle".
It is also important that the feed pump always runs with a back pressure of at least 1 bar. This is
necessary to let the pump run in its Q / H curve and does not suffer any damage due to overload or
cavitation. The pump pressure can be read on the mounted pressure gauge.
2.1 Display and buttons
The SEM Compact Breaktank is equipped with a digital display. The display shows all relevant
information.
Switch on the power supply:
After switching on the mains voltage, the break tank will show the software version on the display for
3 seconds. Changed settings will always be remembered after a power failure.

3. Installation guidelines
When unpacking, check the Breaktank for damage, visible defects, etc. caused by transport. Contact
SEM Water Treatment within 4 working days.
3.1 Hydronic installation
• Place the Breaktank on a flat surface or use the optional wall mounting bracket. Preferably in
the vicinity of a wall socket (230V), a cold water faucet and a sewer connection.
• It is recommended to provide the water supply with a shut-off valve and 500u filter. The
connection size of the water supply is 1/2 "F.
• The connection dimension on the discharge side of the break tank is 25 mm F Glue sleeve.
• The rectangular overflow opening may not be closed.
• The free outlet connection ¾ "F can be connected to a sewer with a 32 mm pipe.
• The drain (drain) connection has a ½ "plug. This allows the tank to be emptied.
• The installation example below gives a good idea of how the break tank can be connected to
the circulation system. Always ensure that fresh water is added to the filter, but after the
measuring point of the automation (W.H.V.B.Z requirement)
The overflow must always have a free range. The overflow may never be closed. The
breaktank will no longer function properly when the overflow is closed.

!
3.2 Electrical installation
The SEM Breaktank works on 230V / 50Hz. This tension is life-threatening. Leave the work on
the electrical installation to the professional.
• Provide a wall socket near the Breaktank. Since the break tank is often located in a damp room
(such as boiler houses and engine rooms), it is wise to choose a spray-free type. It is
recommended to connect the Breaktank behind an earth leakage switch.
• If necessary, the wall socket can be switched off by means of protection contacts of, for
example, flowmeters and / or thermal contacts of the swimming pool pumps, etc.
• Use signal cable of at least 2x0.22 mm for the control signal of the float switch. The maximum
cable length may be 50m.
• A connection for two solenoid valves (24Vdc / 8W) has been prepared on the terminal block, for
example:
• 1x solenoid valve: option large capacity (connect to terminal VALVE 1 + 24V and OUT)
• 1x solenoid valve: option n.t. with this model (connection to terminal KLEP2 + 24V and OUT)
• 1x relay contact that switches on water demand, ie as soon as the pump is switched on.

3.3 Commissioning
• Check the level of measuring hose that is placed in the reservoir. This can be shifted by
transport. The hose must be placed at the bottom.
• The pump is below water level and does not need to be filled manually. However, the filler cap
can be loosened for a moment to allow the air to escape. The pump will then self-aspirate.
• Switch on the mains voltage. The display shows the software version for 3 seconds.
• Open the water supply to the tank, the tank will fill up until the high level is reached.
• Check in the service menu whether the tank is filled to 210mm (+/- 5mm). If the level
measurement does not indicate 210mm (+/- 5mm) for a filled container, the measuring hose
must be pulled fully upwards, above the water level and re-inserted into the holder. This is a
calibration of the measuring system. If the level is still not 210mm (+/- 5mm), please contact
SEM Waterbehandeling B.V. After this check the break tank is ready for use.
• If the level switch in the pool is "interrogative" (float down, contact closed) then after a delay
of 15 sec. the pump will start running. If the float of the level switch goes up (float up, contact
open), the pump will switch off after a switch-off delay of 10 seconds. stop. (factory settings)
• If the reservoir is empty, the pump will also switch off (low level reservoir, Lb = 8cm). Only
after the level has risen again above La = 14cm, it will be released again for use, making sure
that the pump is not damaged by running dry.
• Adjust the flow of the pump until the pressure gauge indicates at least 1 bar.
Pay attention:
- Never allow the pump to run dry, always bleed when commissioning.
- It is best to adjust the tap on the pump so that the tank is barely emptied faster by the
pump than that it is filled by the filling connection.
- In the event of frost, the tank and the pump must be completely drained to prevent
damage due to freezing.Let op:

4. Maintenance and service
In normal use, the break tank requires little maintenance. A few points of interest:
• After being installed or drained, the delivery pump must be vented. To do this, remove the drain
plug from the filler opening at the top of the pump housing. After the pump housing has been
completely filled, the pump can be switched on. Never let the pump run dry!
• Make sure that the feed pump always works with a minimum back pressure of 1 bar. This is to
keep the pump running in its Q / H curve and to prevent damage to seal and impeller.
• The float switch is in a R.V.S. basket built. This is to prevent faults from pollution. However,
grease deposits and small dirt particles can still affect the operation of the float switch
(especially when mounting in a skimmer, for example). From time to time the float should
therefore be inspected.
• Spare parts are always available at SEM Water Treatment.
• The operating hours of the pump can be read in the service menu.
