THE FOLLOWING INSTRUCTIONS ARE REQUIRED
TO BE MET TO AVOID PERFORMANCE FAILURE.
• Do not use anything other than the specified items such
as twin tubes, and rubber hoses etc.
Use flexible stainless pipes that are 50 cm or less only
when position adjustments of the connection are
necessary.
(Otherwise, it may cause problems such as heat pump
unit failure, increased water leakage, and foreign
matter entering the tank etc.)
• Pipe according to the requirements of the piping
material.
2
• The height difference of the inverted U-shaped piping
should be up to a+b<3 m with only 1 inverted U-shaped
piping.
• Cover the tips of the pipes until they are connected to
prevent foreign matter from entering.
• Make sure to connect the piping without mistaking the
hot water side and cold-water inlet side. (Otherwise,
operation will stop)
• For the heat pump unit pipes and connecting parts, use
gaskets that can withstand a water quality containing
high temperature chlorine.
Only use materials that the manufacturer approved as
suitable.
• A 20 Nm (15 to 25 Nm) pipe fastening torque is used for
the work example, but use the torque recommended by
the manufacturer of the gasket you are using.
(Otherwise, it may cause water leakage over time)
1 Remove the piping cover. [Refer to section 2.3.4]
2 Set the gasket onto the pipe.
3 Hand-tighten the screw part straight until it is
properly fastened.
4 Lightly pull the pipe, and check that the flange tip of
the pipe and the nuts are closely attached and are
not wobbling. (Otherwise, it may cause damage to
the screws or water leakage)
5 Fasten with 20 Nm (15 to 25 Nm) using a
torque wrench.
• Make sure to use a spanner to hold it in place
as you fasten with the torque wrench.
6 After confirming that there are no water leaks,
perform insulation.
• Prevent heat loss and freezing by installing insulation
material in a way so that the connecting parts are
not exposed.
• Use weather resistant materials for the insulation
material.
