摘要： An exteriorly installed therapeutic spa has a water circulation loop, including an electric heater for heating the water, an electric motor-driven pump for circulating the water at low and high speeds and electric motor-operated blower for injecting air into the water. Control is effected by an in-house control panel within a residence, a spa side control unit mounted on the spa shell for access by the spa occupant and a main control panel at an equipment area. The control system incorporates a low voltage transformer and rectifier to provide low voltage DC. The spa side control unit utilizes a plurality of low voltage hermetically sealed switches under manual knob control, acting in parallel with in-house control panel low voltage switches. Low voltage relays responsive to low voltage switch operation control operation of the equipment within the equipment area under thermostat control with high voltage override manual switches at the main control panel. Vacation switches within the house and at the main control panel selectively disable at least the in-house switches and insures low flow velocity circulation of the water and heating of the same responsive to freeze thermostat switch closure.
摘要翻译：外部安装的治疗温泉具有水循环回路，包括用于加热水的电加热器，用于以低速和高速循环水的电动马达泵和用于将空气注入水中的电动鼓风机。控制由住宅内的内部控制面板，安装在温泉外壳上的温泉侧面控制单元进行，由spa乘客进入，设备区域设有主控制面板。控制系统采用低压变压器和整流器来提供低压直流电。温泉侧控制单元在手动旋钮控制下使用多个低压气密密封开关，与内部控制面板低压开关并联起作用。低电压继电器响应低电压开关操作，在主控制面板的高压超驰手动开关的恒温控制下，对设备区域内的设备进行控制。房屋内和主控制板上的休假开关至少选择性地禁用内部开关，并确保水的低流速循环和对冷冻恒温器开关闭合的响应的加热。

摘要： A job site formed double sealed, double wall insulated spa pipe coupling is effected between two axially connected coupling components each having a plastic inner pipe and a concentric plastic outer pipe of considerably larger diameter with the pipes being connected by in situ foam insulation filing the space between the pipes. One component has the outer pipe and the foam insulation severed to expose the bare outer periphery of the inner pipe over a short length. The second component similarly formed includes a radially enlarged section over a short length to define a radially enlarged hub. An annular cylindrical collar of a length equal to the length of the hub is adhesively fixed on its inner periphery to the outer diameter of the outer pipe of the first component. The bare inner pipe is adhesively coated and fixed insertably into the interior of the radially enlarged inner pipe at said hub and an annular cylindrical coupler having a length equal to the combined axial length of the collar and the hub and having an inner diameter equal to the outer diameter of the collar and hub is adhesively sealed concentrically about the collar and hub to complete the double sealed pipe coupling.
摘要翻译：工作现场形成双重密封，双壁隔热水疗管接头在两个轴向连接的联接部件之间进行，每个连接部件均具有相当大直径的塑料内管和同心塑料外管，管道通过原位泡沫绝缘连接空间管道之间。一个部件具有外管，并且泡沫绝缘体被切断以在较短的长度上露出内管的裸露外周。类似地形成的第二部件包括在较短长度上的径向扩大部分以限定径向扩大的轮毂。长度等于轮毂长度的环形圆柱形套环的内周与第一部件外管的外径粘接固定。裸内管被粘合地涂覆并固定在所述毂处的径向放大的内管的内部，以及环形圆柱形联接器，其长度等于套环和毂的组合轴向长度，并具有等于轴环和轮毂的外径以套筒和轮毂相同的方式被密封地密封以完成双重密封的管接头。
