Operator Training And Handover Of The Unit - Mandik CPV Installation, Commissioning And Maintenance

MANDÍK CPV Installation, commissioning, and maintenance
All dampers must be in the maximum open position when changing settings.
If the required air output cannot be achieved, this indicates an inspection of the unit (internal
clogging, foreign local pressure resistances) or ductwork (foreign local pressure resistances,
design external pressure loss does not match the actually installed ductwork), etc. is
required.
An entry on the changes to unit settings must be recorded in the corresponding protocol.
The measured values are considered suitable if the deviation between the measured values
and the values in the technical specifications of the unit do not exceed +-10%.
Changes to air output must be conducted per the pressure conditions specified in the project
or by the type of operation inside the conditioned space: equalized pressure, positive-
pressure or negative-pressure ventilation.
The control protocol must specify the following information:
• Identification of the equipment (order number, serial number, position in the project)
• Details as to the person making control changes, including their signature and stamp
• Nominal parameters of the equipment (air output, fan motor current ratings –
nameplate values)
• Measuring instruments in use
• Functional schematic of the equipment, including a schematic of the ductwork with
dimensions and specification of components (inserted elements – attenuators, filters,
etc., control dampers, tees, elbows, etc.)
• A list and the values of measurement points
• Schedule of the control process (start-up of the unit and shut-down of the unit)
• Climactic conditions during operation of the unit (initial and final temperatures and
humidity of the supply and return air)
• A record of operation and the status of individual parts of the unit specified in
subsection 7.1
• A record of any identified defects
• A record from evaluation testing (results, date, etc.
• A table of measured and set values for the individual fans (air output, currents, etc.)

8.5 OPERATOR TRAINING AND HANDOVER OF THE UNIT

The following steps must be performed during training:
• User training for operation and maintenance of the unit
