IMPORTANT!
While venting the exchanger you should pay special attention to securing the device against accidental penetration of water into electrical elements.
IMPORTANT!
Follow the instruction below, when draining the heating medium:
●
Close the shut-off valves before and after the device;
●
Close the control valve;
●
Unscrew the vent;
●
Unscrew the drain;
●
Wait until the exchanger has been completely emptied;
●
Connect compressed air to the exchanger and blow away the remaining water;
●
Close the drain and vent.
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 assembly).
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 passes are located on the back side of the curtain : (1) – control wire packing , (2) – power
wire packing. The access to the terminal strip is obtained by means of removing the side cover (3) from the motor's side.

IMPORTANT!
The specification of cables and protections refers to unbounded arrangement of cables (basic execution of the E installation according to the PN-IEC 60364-5-523 standard). One
should always abide by the local laws and recommendations concerning device connection.
DEFENDER 100-200 is equipped with a terminal strip adjusted to an appropriate thickness of wires.

IMPORTANT!
●
It is recommended to connect wires to the terminal strip with previously clamped appropriate clip ends.
●
Make sure that the space around the place where the air is sucked in by the curtains, as well as around the exhaust grid, is free of any structural elements of the building, which might
hamper the flow of air (e.g. suspended ceilings, covering development, ventilating ducts etc.).
