<p>PURPOSE:To contrive to simplify the adjusting of the second valve and obtain the adequate temperature hot-water in a short time at the operation of the titled device by a method wherein the first valve, a pressure indicator and the second valve are connected to a water supplying pipe of a can body having a heat exchanging function. CONSTITUTION:An indicating needle 14 of a pressure indicator 12 is arranged in a housing case 13. The indicating needle 14 is structured to be moved up and down interlocked with the increasing and decreasing of primary water pressure, the primary water pressure receiving part is connected to a communicating pipe 15. A pressure indicator 12 is arranged between the second valve 8 and a can body 1. After the second valve 8 is opened fully, the first valve 7 is adjusted to obtain an adequate pressure, then the fine adjustment is performed by the second valve 8 at the hot-water supplying operation, accordingly, the hot-water temperature adjustment is enabled by the guide of the pressure indicator 12 in a short time.</p> |
