Check overall working of the
flow controller (only for
rooftops with water
condensation function)
Cut-off the compressors, stop the water circulation, then start
the unit, wait for the water flow failing signal in the controller.
|
Check the water flow ( only
for rooftops with water
condensation function )
Measure the water flow and compare it to the initial value set
in the command selection
|
Check the blower plug fans (
freewheel)
Check the rotation of the fan (free rotation, detection of
vibration or bearing noises)
Check for the Amps consumed on all three phases; compare
with the nominal value given in the electrical wiring diagram.
•
Check the axial extractor fan (
if the unit is equipped with )
Check the rotation of the fan (free rotation, detection of
vibration or bearing noises)
Check for the Amps consumed on all three phases; compare
with the nominal value given in the electrical wiring diagram.
|
Check the well working of the
energy recovering wheels Check the rotation of the wheel; Check the strap tension;
Replace the components in case of malfunctioning
|
Check Airflow rate safety
switch (if equipped). Shut down supply fan. The fault must be detected within 5
seconds.
•
Check freeze protection on
HWC (if applicable) Test antifreeze function (leakage rate, frost protection
thermostat)
|
Check economizer actuator
operation
Check all fixings and transmission. Stop the unit using the
control. The fresh air damper must close. Start the unit, the
fresh air damper should open.
Make a forced opening and closure of the motorized dampers.
|
Check tightness of all
electrical connections
Power down the unit and check and tighten all screws, terminal
and electric connections (including the terminal boxes)
When turning on the unit, check the deterioration of the
electrical components with a thermal camera, with the unit
working at 100% of its power.
|
Check HP safety switches
Install a pressure gauge HP and check if the safety switches
overall working.
|
Check the value of the analog
sensors
Install the pressure gauge calibrated to check the analog sensors.
Install a thermometer calibrated to control the sensors.
Check with a calibrated anemometer the flow rate displayed by
CLIMATIC
|
Check the position of all
sensors Check the position and fastening of all sensors and their
accessories (pressure tapping tube).
•
Check and clean if necessary
all fresh air grids
Check the fresh air grilles (if fitted). If dirty or damaged, remove
them from unit and clean with high pressure water cleaner.
Refit on unit once clean and dry.
•
Check electric heater element
for excessive corrosion
Turn off the unit; Pull the electric heater out of the heater
module box and check the resistances of traces of corrosion;
Replace resistance as required;
|
Check anti-vibration
mountings, for wear and tear. Visually check anti-vibration mountings on compressors and
centrifugal fan. Replace if damaged.
