9.3 Unit booklet
It’s advisable to create a unit booklet to take notes of the unit interventions.
In this way it will be easier to adequately note the various interventions and aid any troubleshooting.
Report on the booklet:
•
date
•
intervention description
•
carried out measures etc.
9.4 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.
9.5 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
9.6 Outdoor 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.
9.7 Outdoor air coil
Contact with the exchanger ns can cause cuts: wear protective gloves to perform the above described operations.
The nned surfaces of the cooling coils and, in particular, the condense collection bowls constitute places where microorganisms and moulds
greatly ourish.
It is very important to foresee periodical cleaning with suitable detergents and, eventually, disinfect with sanitising products.
