DECOMMISSIONING
8.1. Seasonal Shutdown
•
The Aegis heat pump water heater is designed for year-round operation. In the case
that prolonged shutdown is expected, be sure to follow these steps
•
Disconnect the voltage using the machine master switch/main isolating switch
.
•
Drain the hydraulic system (unless it contains glycol water).
•
Repeat the procedure outlined in Section 6 on successive start-ups.
8.2. Emergency Stop
To stop in an emergency, turn OFF the main switch to power off the entire machine.
I M P O R T A N T
Never modify the internal electrical connections, otherwise the warranty is immediately
rendered null and void.
Disconnect voltage from the unit only in the case of prolonged shutdowns, to leave the
compressors guard heating resistances powered.
W A R N I N G
Do not use the main power switch to enable or disable the heat pump: this device should be
used to isolate the unit from the power supply when the unit is OFF. Removing voltage
entirely depowers the guard resistances, jeopardizing the integrity of the compressor.

PERIODIC MAINTENANCE AND INSPECTIONS
W A R N I N G
Before performing any service on the unit or accessing internal parts, make sure that the
power supply has been disconnected.
The inverter of the compressor contains various parts that remain live for a few minutes after
the power supply has been disconnected at the main switch.
Before any maintenance:
•
turn off the machine at the main switch;
•
wait at least 5 minutes;
•
use a multimeter to make sure there is no voltage at the heads of the clamps;
•
make sure the motor has completely stopped;
•
check that the dissipator is not hot: contact with the dissipator can cause burns.
Pay special attention when operating near the finned coils as the aluminum fins are particularly
sharp. The compressors, the flow pipes and the dissipator of the inverter are hot.
