Unit booklet
Foresee a unit schedule to keep trace of the interventions made
on the unit.
In this way, it will be easier to adequately schedule the various
interventions and facilitate any troubleshooting.
On the schedule note:

date
 intervention description

carried out measures etc.
Standby mode
If foreseen a long period of inactivity:

turn off the power
 Prevent the risk of freezing (use glycol or empty the system)
disconnect voltage to avoid electric risks or damages following
lightning
With lower temperatures keep heaters turned on in of the
electrical panel (option).
It is recommended to have a qualified technician start the system
after a period of inactivity, especially after seasonal stops or for
seasonal switch-overs.
When starting, follow the instructions in the “start-up” section.
Schedule technical assistance in advance to avoid hitches and to
guarantee that the system can be used when required.
System drain
The system must be drained only if necessary.
Avoid draining the system periodically; corrosive phenomena can
be generated.
1 Empty the system
2 empty the exchanger, use all shut-off valves and grub screws
3 blow the exchanger with compressed air
4 dry the exchanger with hot air; for greater safety, fill the
exchanger with glycol solution
5 protect the exchanger from air
6 take the drain caps off the pumps
Any anti-freeze liquid contained in the system should not be
discharged freely as it is a pollutant. It must be collected and
reused.
Before start-up, wash the system.
