Safety Measures
The blocks with built-in assemblies which can generate
certain injury hazards (electric shock, rotating parts, etc.)
and connection points (heating water inlets/outlets, air flow
direction, etc.) are always labelled with warning or informa-
tion labels.
It is forbidden to start the fans of the air-handling unit if
the panels are open or removed, or without fixed protecting
guard covers. The hazard of trapping by movable parts is
indicated by a label situated on the service door of the air-
handling unit. Service doors must always be closed during
air-handling unit operation.
Before starting any work on the fan block, the main
switch must always be turned off and secured to avoid
accidental starting of the motor during service work on the
fan block.
When emptying the heat exchanger, the water tempe-
rature must be below +60 °C. The connecting piping of the
heater must be insulated so its surface temperature will not
exceed +60 °C.
It is forbidden to remove the service panel of the
electric heater if energized.
It is forbidden to operate the electric heater without the
outlet air temperature control and without ensuring a stea-
dy flow of transported air.
Controlled run-down of the fans must be ensured
upon gas heater burner shutdown to avoid the exchanger
overheating, and simultaneously, the outlet air temperature
behind the gas heater, respectively the ambient temperatu-
re of the burner, must not exceed 40 °C.
After being set by an expert, the parameters of the gas
heater block must stay unchanged to maintain safe and
trouble-free operation.
Protection against Dangerous Contact with
Non-Live Parts
The protection against dangerous contact of non-live parts
is performed by design measures ensuring electrical con-
ductivity: spot-welds, screw joints with fan washers, inter-
connection with protective conductor (PE) in accordance
with ČSN EN 60439-1.
Inspection Prior to First Start-Up
The service panels are provided with hinges and external
closures. The closure simultaneously serves as a handle.
A special tool – a wrench - is needed to open/close the
closure.
This wrench is delivered with each fan section and can
also be delivered as a spare part (code Z03410058).

Air Handling Units
General Routines and Checks
Check alignment of the air-handling unit.
Check whether all components of the air-handling unit
are installed and connected to the air distributing ducting.
Check whether all cooling and heating circuits are co-
nnected, and whether energy media are available.
Check whether all electrical appliances are connected.
Check whether all condensate drainage kits are conne-
cted.
Check whether all M&C components are installed and
connected
Electrical Wiring
