Water Piping and Water Circuit Connection

General Considerations
Followings should be considered before beginning water circuit connection.
• Service space should be secured.
• Water pipes and connections should be cleaned using water.
• Space for installing external water pump should be provided.
• Never connect electric power while proceeding water charging.
Water Piping and Water Circuit Connection
While installing water pipes, followings should be considered :
• While inserting or putting water pipes, close the end of the pipe with pipe cap to avoid dust entering.
• When cutting or welding the pipe, always be careful that inner section of the pipe should not be
defective. For example, no weldments or no burrs are found inside the pipe.
• Pipe fittings (e.g. L-shape elbow, T-shape tee, diameter reducer, etc) should be tightened
strongly to be free from water leakage.
• Connected sections should be leakage-proof treatment by applying tefron tape, rubber bushing,
sealant solution, etc.
• Appropriate tools and tooling methods should be applied to prevent mechanical breakage of the connections.
• Operation time of flow valve(e.g. 3way valve or 2way valve) should be less than 90 seconds.
• Pipe is insulated to prevent heat loss to external environment.
