1) Drill four fixing holes (refer to drilling spacings) into the load-bearing ceiling, insert
dowels and fit the appropriate M8 threaded rods.
2) Using M8 fender washers and nuts, fix the threaded rods to the four corresponding fix-
ing brackets on the unit and secure them in place (with self-locking nuts or locknuts).
3) Then dismantle the design panel from the supply lines:
4) open the design panel by pulling on the notches.
5) Push the securing panel inwards to unlock the design panel and open it fully. CAU-
TION: When opening/removing the design panel, do NOT allow the opening angle to
exceed 90° to prevent damage!
6) Unlock the hinges on the right and left by pulling on them and remove the design
panel.

Pre-commissioning checks
During initial commissioning, it must be ensured that all necessary requirements are met so that
the appliance can function safely and as intended.
Electrical tests
Check whether all lines have been properly laid.
Check whether all lines have the necessary cross-section.
Are all wires connected in accordance with the electric wiring diagrams?
Is the earth wire connected and wired throughout?
Check whether the fault signal contacts of the EC fans have been correctly connected
(break contacts in series with multiple units).
Check all external electrical connections and terminal connections are fixed in place and
tighten if necessary.
Water-side checks
Check whether all supply and drainage lines have been properly connected.
Fill pipes and unit with water and bleed.
Check whether all bleed screws are closed.
Check leak tightness (pressure test and visual inspection).
Check whether the parts carrying water have been flushed through.
Check whether any shut-off valves fitted on site are open.
Check whether any electrically actuated shut-off valves have been properly connected.
Check whether all valves and actuators are working properly (note permitted mounting pos-
ition).
Condensation water connection
Check whether the condensation tray is free of building rubble.
Check the condensation drain and operation of the alarm signal on the condensation pump.
Check whether the cooling valve switches off in the event of an alarm signal.
Check whether the unit is connected leak-free to the on-site condensation connection.
Check whether the waste water lines are clean and have a sufficient gradient.
Check whether the condensation pump has a working power supply.
