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.
