3.
Visual inspection and functional test of the fans; check for free running, check the terminal
boxes for tightness, check for corrosion and noise (bearings)
4.
Check all pipe connections (including pipe clips), electrical components, housings and
attachment parts for tight fit
6.2 Normal operation
For running the unit, the entire plant including the electrical system must be operating. The unit is
integrated in the cooling circuit by opening the corresponding shut-off valves. It is turned on by
activating the electrical system.
After reaching the system-specific operating point the unit is ready for operation.
In case of operating conditions which differ from those stated in the quotation, the manufacturer must
be consulted.
6.3 Cleaning
thermofin® recommends that you periodically carry out certain cleaning measures. The type and
frequency of the measures strongly depend on the respective installation site of the heat exchanger.
When doing any cleaning work, make sure that no electrostatic charge can occur! The
operator must ensure that no explosive atmosphere prevails or arises during cleaning.
Cleaning work on the unit may only be carried out by qualified persons. Under certain
circumstances, the explosion protection could be cancelled. Explosions with fatal or serious
injuries to persons can result.
6.3.1 Cleaning of the fins
Depending on the installation site, mode of operation and the season, the heat exchanger fins are
subject to fouling (varying degree). As this directly affects the performance and thus the current
consumption of the unit, the cleanliness of the finned coil must always be ensured.
Switch off the unit (regarding refrigeration and electricity)! Check that there is no voltage
(safety measurement)!
Dry cleaning: with a vacuum cleaner, broom or a soft brush from the outside towards the
fins
Wet cleaning: with a soft water jet from the inside towards the outside and opposite to the
direction of the air flow of the fans. Prevent bending the fins.
The use of high pressure or steam pressure washers is prohibited!
