7. Construct and fix forerun and return travel of collector (4). If for winter a drain cook is needed
glue a reducing tee with reducing piece 1/2" for the drain cook.
8. Regulation: Pleas e take a look at the instruction for installation and oper ating for the
difference-temperature regulation and the thr ee-way motor ball valve respectively the pump.
Attention should be paid to the ac complishment of electrical installation. Swimming pools
systems have to be equipped with a ear th leakage circuit breaker.
Fasten collector sensor (6) to absorber with clamp. Glue reducing tee with nipple 1/2" f or swimming
pool sensor (7) into pipe coming from the pool and s crew in sensor. Fix the difference-temperature
regulator and fasten it like the wiring diagram.
Use wires with cross-section 2 x 1 mm² to lengthen sensor adaptors.
If you take a pump with mor e than 600 W charging rate or three-phase pumps, you have to install a

Operating Instruction
To start the system adjust the difference temperature to approx. 3 or 4 °C and plac e the hand switch on
automatic. In systems working with filter pumps adjust the filter cycle to the hours of sunshine.
Installations with own pump wor ks independent f rom the filter circuit.
If after a few minutes the system works still with air in it, close the stop cock (downdraft brake) a little until
the water escape at the intak e nozzle is majority free of air. The stop cock now always stay this way.
Additionally you can close the cover cap of the vent valve.
Operating the system in winter
OKU-Absorbers are frost resistant. Due to the pipes the system must be emptied in winter nevertheless.
Usually systems which emptied when they´ re switched off, don´t need any precaution.
Advice to glue pvc pipes
Glue pvc pipes only if they´re absolutely dry. Water, condensates and humidity pr event a good connection.
Don´t glue under a Temperature of 5°C. The time f or drying is circa 24 hours, do not use it
with pressure before.
Clean ends and fittings with a cleaner. Glue both par ts the same way. Take a flat brush.
It´s important to disperse the glue lengthwis e from the inside to the outside.
Directly after apply the glue you hav e to plug ends and fittings together.
Take of the surplus glue. Clean the br ush with cleaner.
