Putting device in operation

Only a person with necessary qualification may put the
unit in operation. Before the first start a qualified worker
must perform a revision of electric installation of all con-
nected components of air handling device.
Safety precautions
Sections with accident risk (by electric current,

rotating elements etc.) or with connecting points (inlet
- outlet of heating water, air flow direction etc.) have
always warning or informative label.
It is prohibited to operate unit fans when the door

is opened or when the panels are removed. Service
panels must be during operation always closed.

Air handling units
Before work on fan part is started, make sure that the

main switch is off and make such moves which will pre-
vent unintentional switching of the motor during mainte-
nance.
When emptying the exchanger the water temperature

must be lower than 60°C. Temperature of connecting
piping must also be lower than 60°C.
Removal of life electric heater service panel is prohi-

bited and changing production setting of safety thermo-
stat is prohibited as well.
Operate electric heater without outlet air temperature

control and without providing steady speed of air flow is
prohibited.
Putting unit in operation at not adjusted installation can
only be done with closed control damper at the inlet to
the unit. Operation of a unit at not adjusted installation
could lead to overloading the motor and to its perma-
nent damage. If second stage of filtration is part of the
unit we recommend to perform a trial operation without
inserts of second filtration degree.
Check during first start-up of unit
rightness of fan rotation direction according to an

arrow on the impeller.
current consumption of all connected devices (may

not exceed value mentioned on the label)
whether the water in the seal-pipe has not been suc-

ked off. The height of the seal-pipe must be raised
state of filter attachment

During trial operation try to notice presence of impro-
per noises and abnormal unit vibrations for at least
30 minutes. Sources must be detected and removed.
During the trial operation perform the adjustment of unit.
Before starting permanent operation we recommend to
regenerate or change filtration inserts. Detailed check
description of a device that is being put in operation is
included in the Service book for REMAK devices, where
according to guaranty requirements the first operation
of the device must be mentioned.
