1. Common faults: Heating overall not hot. Remedy: Turn into the backwater valve. 2. Common faults: Heating is not hot (the valve has been opened). Heating is not half hot. Heating the water within the sound. Remedy: Heating in air may be required to release gas. Method 1: Put the water valve closed. Wind up running the exhaust valve opens, water overflow, close the release valve. Method 2: Close the inlet valve 3 / 4, then backwater valve closed, exhaust valve opening play, when the semi-closed water overflow release valve. Note: It is done, the fault can not be eliminated, notify maintenance staff. 3. Common faults: inadequate heating pipe temperature, room temperature is too low. Remedy: water temperature is low, raise water temperature. By the property inspection system. 4. Fault: into the backwater valve to inside (near the heating direction) leakage. Remedy: Turn off into the backwater valves. Notify the maintenance team to install. 5. Frequently failure: backwater valve into the outside (near the head of Road) leakage. Remedy: notification of property semi-closed system valves; notice installation team for maintenance.
