Operating Checks and Service Regulations

Checking During the First Start-Up
 Check the proper direction of the impeller rotation following the
direction of the arrow on the impeller or fan casing.
 Check the proper direction of the rotary heat exchanger rotation
following the direction of the arrow on the rotor situated under
the service panel.
 Check the input current of connected equipment (it must not
exceed the maximum permissible value stated on the rating plate).
 Check the proper direction of the rotary heat exchanger rotation
following the direction of the arrow on the rotor (from the service
panel side always upwards) and free rotation without dragging.
 After 5 minutes of operation, stop the air-handling unit and check
the temperature of bearings and the tension of belts (belt-driven
fans only). This check may only be performed if the fan is switched
off!
 Check the water level in the condensate draining kit. If the water
has been sucked off, it will be necessary to increase the height of
the siphon.
 Check the mounting of the filters
During the testing operation, it is necessary to check the air-handling
unit for unusual noises and excessive vibrations. The testing operation
must last at least 30 minutes. After the test operation has finished,
the air-handling unit must be inspected. Pay special attention to
filters and check them for damage, the fan section and check the belt
tension, the tightening torques of threaded pins of Taper-Lock collets
(refer to the Table of Taper-Lock collet tightening torques), and proper
functioning of the condensate draining kit.
If the unit vibrates too much, it is necessary to check again the fan
assembly and perform vibration intensity measuring,
if necessary. If vibration intensity of the fan assembly with an
overhung impeller (XPAP section, XPVP assembly) exceeds 2.8 mm/s,
measured at the motor bearing shield on the impeller side, the fan
must be checked and balanced by professional staff. During the
testing operation it is necessary to adjust (regulate) the entire air-
handling system. Before putting the air-handling unit into permanent
operation, it is recommended to replace or regenerate the filter
inserts.
Service Regulations
Before putting the air-handling device into permanent operation, the
supplier (installing company) in collaboration with the designer must
issue service regulations in accordance with local legal regulations.
We recommend including the following in these service regulations:
 Air-handling device assembly description, its intended use and a
description of its activities in all operating modes.

Description of all safety and protective elements and their
functioning.
 Health protection principles, safety and operating rules to be
observed when operating the air-handling device.
 Requirements for operating staff qualifications and training, a
nomenclature list of personnel authorized to operate the air-
handling device.
 Detailed emergency and accident instructions to be followed by
the operating staff.
 Operating particularities during different climatic conditions (e.g.
summer or winter operation).
 Inspection, checking and maintenance schedule, including a list of
checking steps, and their recording
 Records of operating staff training, operation, inspections and
cleaning of the rotary heat exchanger (subject to guarantee
validity).

Unit Operation Screening Checks

Průběžné provozní kontroly klimatizační jednotky se provádí vizuální
a poslechovou kontrolou jedenkrát týdně (denně) bez narušení chodu
jednotky.
The operating staff checking activities must be focused on the following :
 Check the operation and functionality of the air-handling unit.
 By listening, check proper operation of the fans (strange noises
and excessive vibrations of the unit) and, if needed, balance the
fan, refer to the section Unit First Start Inspection.
 Check the casing, doors and service panels for leakage.
 Check the temperature of the media and transported air

Check the condition and operation of the control and sensing
systems associated with the air-handling unit, whose proper
functioning is necessary for proper operation of the air-handling
unit as well as for operation of the entire air-handling system.
These are:
 Electric wiring
 Measuring & control system (M&C)

Heating system - circuit leak-tightness, pump operation
 Water filter fouling (also in SUMX)
 Cooling system - circuit leak-tightness and function
 Condition of piping insulation
 Sanitary installation - condensate drainage
 Gas heater system

Regular Inspections

The user will determine the intervals for regular inspections of the air-
handling unit according to the operating conditions, however, at least:
a) Once every three months
Check for contamination and possible damage to the basic functional
groups of the air-handling unit:
 Filters (hygiene condition, fouling, unacceptable damage or
perforation)
 Heat recovery, heat-exchangers (functionality, fouling, leakage or
damage)
 Humidification system (hygiene condition, functionality, circuit
tightness, fouling of jet nozzles)
 Condensate drainage (for stagnant water in the tray or elsewhere
in the equipment)
b) Once every six months
 Check all the functional groups of the air-handling unit for
functionality, failure-free state, corrosion, cleanness and hygiene,
including necessary maintenance, cleaning and repair and/or
replacement of damaged parts.
 This inspection is usually carried out in the spring and autumn
months, i.e., before the winter and summer season during a short
downtime of the equipment
c) Once a year
 General service inspection of the air-handling unit for functionality,
failure-free state, corrosion, cleanness and hygiene, including
casing and covering roofs, and necessary maintenance, cleaning
and repair and/or replacement of damaged parts.
 It is carried out mainly in the summer months during a longer
downtime of the air-handling unit.
