Warning: In order to ensure the normal use of your unit, please follow the following tips during the use of (winter, spring): 1. Frequent shutdown, the unit's main power switch and the single-pole air switch in the electronic control box must be kept closed and energized.

2. When the ambient temperature is low, the water temperature is correspondingly low and there is a danger of freezing, the unit will automatically start the anti-freezing program to prevent the occurrence of the accident, but at this time, if you turn off the water pump and the unit power supply, then the anti-freezing program fails, the water temperature will continue to fall to the point that the water system is frozen or even frozen heat exchanger pipe, etc. In order to avoid such accidents, please you must do the following two:

1, the water pump must be linked with the unit, the unit to control the start and stop of the water pump, rather than manual control.

2, the pump and unit main circuit and control loop must be kept energized, if you can not keep the energized state. It is necessary to release the water in the water system in time.

The company's products in the installation and commissioning, if the user needs, can first communicate with the company's technical staff to confirm the site service.
