10.1. Pre-Controls
10.1.1. Control of Power Supply Connection
It should be made sure that 3 phases are provided with neutral and grounding connections correctly.
It should be checked whether the electric supply connection is at ±%5 tension tolerance.
It should be ensured that a supply cable in the right cable diameter is spanned to the device panel.
A “double stranded”, 2x0,8 mm2 knx transmission cable should be spanned between the device’s electric
panel and room control unit.
10.1.2. Control of Additional Heater Connections
It should be checked that hot water connections and gas connections are provided as explained in the
instruction manual and on the right inlet and outlet points.
It should be checked whether manual control valves were placed at inlet and outlet of hot water coil.
It should be ensured that there are no valves or counter slopes on drainages.
It should be ensured that human exposure to drainages connected to waste water installation isn’t
possible.
10.1.3. Control of Air Duct Connections and Air Filters
It should be checked that all air duct connections (exhaust, fresh air, absorption ducts from the ambient,
blow ducts to the ambient) are made to the right connection parts.
It should be ensured that flexible material (tarpaulin) is used especially in connections of absorption duct
from the ambient, blow duct to the ambient.
It should be made sure that probable sound absorbers are connected.
It should be ensured that blow and absorption ducts were isolated.
It should be checked whether blow part and filters at the area are attached at the first operation. These
filters should be mounted to their places after the first operation. Otherwise, filters may get dirty early.
