VENTING OF DEVICE/DRAINING OF HEATING MEDIUM
Venting of the curtain water coil followed by loosening the union connection on the outlet connection. In case of the vertical installation with the coils connection on the bottom side, the access
to the vent valve is by removing the side cover. To do it one should remove the screws (1) around the cover and lift the cover. There is a valve (2) with a hose.

IMPORTANT! While venting the exchanger you should pay special attention to securing the device against accidental penetration of water into electrical elements.
IMPORTANT! Remember to vent the heater, if it has been activated after a prior draining of the heating medium.
IMPORTANT! Pay particular attention to the leak-tightness of connections, when filing the hydraulic system. Make sure that the water flowing from a leaky connection does not leak to the
electric engine (at the vertical instaallation).
CONNECTING OF POWER SUPPLY
IMPORTANT! The system must be equipped with protective equipment that guarantees the disconnecting of the device on all poles of the power source.
Connection to the electric system must be performed by a duly authorized and qualified person. Wire grommets are located on the back side of the curtain, a per drawing below.
CABLES CROSSING BETWEEN THE GLANDS AND TERMINAL BLOCK
To ensure proper separation between high and low voltage cables, follow below wiring instruction:
Power supply cable (high voltage)
• Cross the cables through the central gland (No. 1 on the drawing above).
• Cross the cable through the central mounting point and tight the strain relief.
• Gently pull the cable from outside to make it straight between the gland and mounting point. Then tighten the
gland.
• Connect the wires to the relevant high-voltage terminals.
Heating stages control H & H (High voltage)
1 2
• Cross the cables through the gland no. 2 on the drawing above.
• Cross the cable through its mounting point (see diagram on the right) and tight the strain relief.
• Gently pull the cable from outside to make it straight between the gland and mounting point. Then tight the
gland.
• Connect the wires to the relevant high-voltage terminals.
Low voltage cable (0-10 volts fan revolutions control (low voltage)
• Cross the cable between the small gland no 3 on the drawing above.
• Mount the cable to the top mounting arm of the motor using cable tie (supplied with the curtain kit) – auxiliary
mounting point no 1.
• Cross the cable through its mounting point (see diagram on the right) tighten the strain relief.
• Cross the cable through auxiliary mounting points no 2 and 3.
• Connect the wires to the relevant low-voltage terminals.
• Gently pull the cable from outside to make it straight between the gland and mounting point. Then tighten the
gland.
