Glycol systems

6.1

Installation instructions (only to be carried out by an expert)

Please bear in mind that the internal unit and the outer part of the system are matched to one another
technically. All warranty claims will be rendered null and void if third-party components are used. Ensure
that there is optimal and draught-free air distribution and there are minimum clearances. Ensure that the
electrical connections in the terminals are attached properly. Take the weight of the external unit into
account and select a location where noise and vibration are reasonable.
10. The unit contains a glycol pump. Observe the maximum lift height of 15 m and the pipe length
of 80 metres (maximum distance from unit to heat exchanger is 40 m).
The connection of the units is best achieved with PA tube, OD 15 mm / ID 12 mm, P/N 22-0092-035
as this tube is suitable for both glycol and for plug connectors with a diameter of 15 mm. You will require
a total of 6 plug-in connectors, 2 of 15 x 15 mm, P/N 14-9816-014 and 4 15 x 12 mm connectors,
P/N 14-9816-015.
11. The glycol pump is connected to the refrigeration circuit via an internal pipe-in-pipe heat exchanger
in the unit.
12. Install the tube connection from the outlet of the unit heat exchanger to the inlet of the external heat
exchanger. A 3-core 3 x 0.75 mm cable must also be laid from the pump unit to the external heat
exchanger in order to control the fan motor.
13. Lay the tube connection from the external heat exchanger to the pump unit. Make sure that the tubes
are laid free of kinks for all connection lines.
14. Attach the cable to the external heat exchanger on the terminal block on the heat exchanger and attach
the other end of the cable to the terminals on the unit.
15. Make a mixture of 30% glycol and 70% water (approx. 5l) and put approx. 2l into the pump's storage tank.
16. Fill the water basin of the refrigerating unit and start the refrigeration process. The carbonator pump and
circulating pump must remain switched off during this process. The glycol pump and the internal and
external fans start up when the compressor starts.
17. Top up the glycol mixture in the pump's storage tank until air bubbles no longer appear on the pump's
return tube.
18. Check whether the fan of the external heat exchanger is also working in parallel with the pump.
