8.4 Standby mode
If a long period of inactivity is foreseen:
•
turn o the power
•
avoid the risk of frost (empty the system or add glycol)
Turn o the power to avoid electrical risks or damages by lightning strikes.
With lower temperatures keep heaters turned on in of the electrical panel (option).
It’s recommended that the re-start after the stopping period is performed by a qualied technician, especially after seasonal stops or seasonal
switching.
When restarting, refer to what is indicated in the “start-up” section.
Schedule technical assistance in advance to avoid hitches and to guarantee that the system can be used when required.
8.5 Water side exchanger
It is very important for the exchanger to be able to provide the maximum thermal exchange, therefore it is essential for the inner surfaces to
be clean of dirt and incrustations.
Periodically check the dierence between the temperature of the supply water and the condensation temperature: if the dierence is greater
than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be eected:
•
with circulation opposite to the usual one
•
with a speed at least 1,5 times higher than the nominal one
•
with an appropriate product moderately acid (95% water + 5% phosphoric acid)
•
after the cleaning rinse with water to inhibit the action of any residual product
8.6 Water lter
Check that no impurities prevent the correct passage of water.
8.7 Circulating pumps
Check:
•
no leaks
•
bearing status (anomalies are highlighted by abnormal noise and vibration)
•
the terminal protection covers are closed and the cable holders are properly positioned
8.8 Flow Switch
•
controls the operations
•
remove incrustations from the palette
8.9 Electric fans
Check:
•
the fans and the relative protection gridsare well xed
•
the fan bearings (evident by noise and anomalous vibrations)
•
the terminal protection covers are closed and the cable holders are properly positioned
8.10 Air coil
Contact with the exchanger ns can cause cuts: wear protective gloves to perform the above described operations.
It is extremely important that the battery gives the maximum thermal exchange; therefore, its surface must be cleaned from dust and deposits.
Remove all impurities from the surface.
Using an air pressure gun, clean the aluminum surface of the battery; be careful to direct the air in the opposite direction of the fan air
movement.
Hold the gun parallel to the ns to avoid damages.
As an alternative, vacumn cleaner can be used to suck impurities from the air input side.
Verify that the aluminum ns are not bent or damaged, in the event of damages contact the authorized assistance center and get the ns
straightened in order to restore the initial condition for an optimal air ow.
