DANGER
Risk of electric shock and injury due to moving parts .
Working with the power supply switched on can result in serious injury . Ensure you follow the
personnel requirements outlined in the section titled Safety .
Before performing the winterisation procedure, ensure the unit is switched off and isolated
from the mains power supply .
As the heat pump contains electrical and moving parts, it is strongly recommended that only
a competent person carries out the winterisation procedure for your safety .
Drain Down Procedure for Frost Protection and Corrosion Prevention:
1 . Isolate the mains power supply to the heat pump .
2 . Remove external fuses from the heat pump mains supply and store them safely away from
the heat pump to prevent accidental operation .
3 . Ensure the water circulation pump is switched off .
4 . Drain the water from the heat pump by disconnecting the pool water pipework to and
from the heat pump .
5 . Flush the heat pump's water circuit using clean tap water (do not use pool water) . Use a
hose connected to the water outlet connection and flush for at least ten minutes . If available,
use a spray nozzle for more effective cleaning .
6 . Allow any remaining water in the heat pump's water circuit to drain, then cover both the
inlet and outlet water connections with plastic bags secured by elastic bands .
7 . Uncover the heat pump connection terminals (refer to the section titled Power Connec-
tion) and spray the interior of the enclosure with a moisture-repellent aerosol, such as WD-40 .
Once done, reseal the enclosure .
8 . If the heat pump is installed outdoors, protect it from the weather by covering it with a
vented winterisation cover . Do not use plastic sheeting, as condensation can form inside the
heat pump . .
NOTICE
If the winterisation procedure is not adopted and frost or corrosion damage results then the
warranty will become invalid .
