HORIZONTAL ASSEMBLY

OPTION I: Assembling handles with their arms faced downwards.

In this option you should fi rst screw the installation handles to the wall (1) and then at regular intervals (for a 1m curtain it is 2 installation hanles every 700mm, for 1.5m – three , 2m - four installation handles every 600mm) so that the handles' arms are levelled. Then slide 2 (DR -1m), 3 (DR-1.5m) or 4 (DR-2m) assembly screws (2) M10x20 in each of the two guide bars. Lift the curtain with the screw faced upwards and assemble them in the handles. Put backing straps (3), tighten the nuts (4) and close the handle's covers (5).
ATTENTION! The minimum distance between the unit and the ceiling should be 0.3m.

OPTION II: Assembling handles with their arms faced upwards.

The assembly consists in attaching the installation handles to the unit (1) at regular intervals as in OPTION I In order to do so you should slide 2 (DR -1m), 3 (DR-1.5m) or 4 (DR-2m) assembly screws (2') M10x80 in each of the two guide bars and knock out holes (6) on the outside of covers (5) with the use of a hammer and a screw and then close the handles' covers (1). Put the handles on the screws, put backing straps (3) and tighten the nuts (4).
In this assembly option you can fi rst assemble the handles to the curtain and than screw the whole down to a wall.
ATTENTION! The minimum distance between the unit and the ceiling should be 0.3m.

VERTICAL ASSEMBLY

It is possible to assemble Defender to a wall vertically on both sides of the gate (with the motor on the bottom or on the top).
For this option it is not important if you screw the handles down to the unit fi rst and then screw the whole down to the wall or fi rst attach the handles to the wall and then screw the curtain down to the handles. In the case of vertical assembly you should use the provided screws M10x80 and M8x80. 1, 2, or 3 handles should be attached with the use of screws (2) M8x80, through a backing strap (3) to the threaded sleeve (7) installed in the unit's guide bar (zoom A). The handle on the side of the exchanger's connection pins should be mounted on screws (2’) M10x80 slid in guide bars (as in the case of horizontal assembly), put a backing strap (3') and tighten the nut (4) (zoom B).
IMPORTANT: In case of vertical assembly the minimal distance between the device and the fl oor (150mm) for access to the water coil blowdown connection and the cable terminal should be
provide.

VENTING OF DEVICE/DRAINING OF HEATING MEDIUM

The access to air vents / agent escapes is obtained by means of removing covers / hole plugs 1, 2 or 3 depending on the way of assembling Defender. When using a 13 mm fork spanner or
screwdriver you should loose the screw of an appropriate service valve:
- venting: position A and B – service valve II with the fl exible pipe, position C – service valve III,
- escape: position A – service valve I, position B – service valve III, position C – service valve II.

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 fi ling the hydraulic system. Make sure that the water fl owing from a leaky connection does not leak to the
electric engine (at the vertical assembly).
