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.
• If needed, reserve space for installing external water pump.
• Turn the power off to the unit while filling the water piping.
• Not use Hydro Kit for continuous on demand(instant) water heating application.
Water Piping and Water Circuit Connection
While installing water piping, 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 Teflon tape, plumbers putty
or other thread sealing material.
• 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.
• Wrap all cold surfaces of the pipe system individually with insulation sized to keep condensation
from forming on the pipes in the installed environment. For proper size insulation, use guidelines
provided by the insulation manufacturer.
