outlet of water tank with PPR pipe.
Notes.
(1) For safe use of water, water outlet/inlet of water tank must connect with a certain length of PPR pipe ,L ≥70×R2(cm,
R is inside radius of the pipe). Moreover, heat preservation should be conducted and metal pipe cannot be used.
For the first use, water tank must be full of water before the power is on.
(2) The water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left open to the
