5) Anti-freezing
The water in the unit may freeze when the unit is left unused in winter.
Drain the water system when appropriate if it is not used over a long period. Or you can simply add proper amount of antifreeze
into the water system of the unit.
Mixing water with glycol will affect the unit performance.
Please pay attention to the safety instructions attached to the glycol container.
5.5 Electrical connection
Make sure that the power supply falls within the range of 220-240V~1ph 50Hz/60Hz and is able to provide enough
wattage for the unit. The power supply system must comply with the current national safety regulations.
The electrical connection must be completed by qualified professionals and must comply with local laws and
regulations. The company is not responsible for personal or property damage resulting from any incorrect electrical
connections.
Provide dedicated and suitable leakage protection device for the unit, with a minimum distance of 3 mm among the
wiring contacts. The unit must be grounded reliably.
Make sure that the power cord has a large-enough cross section to withstand the maximum current required. Never
use a damaged cable.
Perform electrical connections according to the wiring nameplate (Figure 5-20 or Figure 5-22) of the unit.
Secure the cable using clamps in the electric control box to ensure the safety of the power supply cable and the
connection cable.
Do not pull, step on or squeeze the cable. Do not use nails or staples to secure the power cord.
The cable must be passed through the knockout hole at the foundation.
An AC contact switch (with contact separation of at least 3mm) must be installed on the fixed wiring to disconnect
the machine from the electrical mains and the omnipolar switch.
