Assembly of KOMPAKT 300HB heater
Consecutive steps.
a. Remove the heater from the wooden pallet by unscrewing 3 safety bolts located on the pallet's back, using S19
wrench.
b. Connect the heater with solar collectors and tap water piping installation, as shown in the schematic diagram of the
installation (Fig. 3), or the schematic diagram of the installation in a warranty card.
c. Connect the wire to the terminal block in place designated for solar collector temperature sensor.
ATTENTION!!! The heater is featured with a safety valve and tap water circuit expansion vessel.
Filling and starting the installation.
The installation should be filled with a proper heat transfer fluid which is a water solution of propylene glycol, with a
solidification temperature of -25°C with an addition of an inhibitor pack, protecting the installation from corrosion.
ATTENTION!!! TERMSOL EKO should not be diluted with water.
System filling with heating medium, with the use of a rotary pump unit.
Consecutive steps.
a. Unit pipes: connect supply pipe to the lower discharge valve (9), and overflow pipe to the upper discharge valve (4).
Fill the unit tank with the heating medium, open discharge valves (4 and 9) and start up the rotary pump.
b. After pumping the heating medium for about 30 seconds, close the ball valve (8) inside the pump control unit (open
valve causes the liquid to flow through the inner element of the pump control unit).
c. Do not switch off the rotary pump until full deaeration of the system –that is, till air bubbles stop appearing in the
overflow pipe.
d. When air bubbles stop appearing in the overflow pipe, close the upper discharge valve (4) and continue pumping
heating medium to the system, to reach system overpressure of p = 2.5 bar, which is measured by pressure gage
(12). When required overpressure is reached, close lower discharge valve (9), switch off rotary pump and open the
ball valve (8).
e. Insert the controller plug into the ~230V mains socket and switch on the solar collector pump in the manual mode. In
order to switch on the pump in a manual mode, one should:
Switch on the controller with the button - CAUTION!! this will calibrate temperature detectors.
Go to MENU pressing the button.
Using the arrow buttons or choose the option „Manual control” and confirm pressing button.
Switch off the pump P manually replacing the option „On” with „Off”.
f. Remaining air should be removed automatically by opening the manual valve (3).
