18. Observe the display on the cold water unit. The
fan of the cold water unit starts up at a water
temperature of 15 °C. The fan cuts out again at a
water temperature of 11 °C.

If a fault message (e.g.
cancel this by simultaneously pressing (for approx. 5
seconds) the two "Clear" buttons (Pos. 1 and 2).

19. Once the fan of the cold water unit has started up,
check the direction of the air flow. To do so, hold a
sheet of paper in front of the cooling fins of the cold
water unit. The air must flow outwards. If this is not
the case, the rotating field direction of the voltage
network is incorrectly set. The electrical connection
of the EPS 708 must then be checked.
20. Check whether the tank and inlet temperatures drop
to 30 °C on the monitor. If this is not the case, check
the valves at the cold water unit (refer to Section
4.11.2).
