There is a hazard of electrical shock from crushing, cutting or heat damage.Remove all packing items applied to space heater for shipment. Remove all items from carton. Check items for any shipping damage. If space heater is damaged, promptly inform dealer where you bought space heater.SERVICE SPACE HEATER SAFELYBefore servicing the space heater, disconnect all equipment and battery (if equipped) and allow unit to cool down.Service space heater in a clean dry flat area.Operator’s Manual 9A -- Hot Air Outlet (Front)B -- Upper ShellC -- HandleD -- Fan GuardE -- Power CordF -- Thermostat KnobG -- Hose / Regulator Assembly H -- Inlet Connector I -- On / Off Switch J -- Lower Shell10 Operator’s ManualOperationOPERATION5. Plug extension cord into a 120 volt/60 hertz, 3-hole, grounded outlet.6. Open propane supply valve on Propane / L.P. tank(s) slowly.Note:If not opened slowly, excess-flow check valve on Propane / L.P. tank will stop gas flow. You may hear a click from the excess-flow check valve closing. If this happens, reset the excess-flow check valve by closing propane supply valve and open again slowly.7. Turn thermostat control knob fully counterclockwise to the "cooler" position. Turn ON/OFF switch to the ON position. Turn thermostat control knob slowly clockwise until electric motor and fan begin to run. Heater will start in approximately 3 seconds. Adjust thermostat control knob to warmer or cooler setting as needed.Note: If heater does not start after 3 seconds, the ignition control will automatically attempt to start heater one time. If heater fails to start on this attempt, the safety control will "lock out" and no further automatic restarts will be attempted. This could occur if air remains in fuel line. If heater fails to start on this attempt, turn ON/OFF switch to OFF position. Wait ten seconds for safety control to reset, then turn ON/OFF switch back to ON position and try to start heater again.8. Thermostat Operation Only: During normal thermostat operation, heater will cycle off when air temperature rises to thermostat setting. When air temperature drops sufficiently below thermostat setting, the electric motor and fan will begin to run. After 15 to 60 seconds, heater burner should automatically ignite and provide heat to maintain temperature setting.STOP SPACE HEATER:1. Tightly close propane supply valve on Propane / L.P. tank(s).2. Wait a few seconds. Heater will burn gas left in supply hoses.3. Turn ON/OFF switch to the OFF position.4.

1.5比例阀调整方法
首先,打开比例阀电路板的盒盖(使用2.5号六方扳手),可以看到如上图中所看到的电路板的大致形状。
(要注意不要损坏了连接电缆)
如果,在作常规流量测试时( test REGULACIÓN ),比例阀的值不再规定的范围内,需要调整A,B电位器的值,A用于正值,B用于负值,顺时针增加,逆时针减少。
一般调整1/4--1/2圈。
如果,在作快速流量测试时(flow test),比例阀的值不再规定的范围内,需要调整c,d电位器的值,C用于正值,D用于负值,顺时针增加,逆时针减少。
一般调整1/4--1/2圈。
调整完之后,要重新测试,进行检查。

凝结水系统讲座主凝结水系统指由凝汽器至除氧器之间相关的管道与设备。
主凝结水系统主要作用是加热凝结水,并加凝结从凝结器热井送至除氧器。
作为超临界机组,对锅炉给水的品质很高,因此主凝结水系统还要对凝结水系统进行除盐净化,此外,主凝结水系统还对凝结器热井水位和除氧器水位进行必要的调节,以保证整个系统的安全运行。
一系统的组成主凝结系统包括两台100%容量立式凝结水泵(型号:C720III-4,)、凝结水精处理装置、一台轴封加热器,四台低压加热器,一台凝结水补充水箱和两台凝结水补充水泵。
为保证系统在启动、停机、低负荷和设备故障时运行时安全可靠,系统设置了众多的阀门和阀门组。
主凝结水的流程为:凝结器热井→凝结水泵→凝结水精处理装置→轴封加热器→8号低压加热器→7低压加热器→6低压加热器→5低压加热器→除氧器。
1 凝结水泵及系统凝结水泵用途:凝结水泵在高度真空的条件下将凝汽器的热井中的凝结水抽出,输送接近于凝汽器压力的饱和温度的水。
1台变频运行1台工频备用。
离心泵的工作原理:在泵内充满水的情况下,叶轮旋转使叶轮内的内也跟着旋转,叶轮内的水在离心力的作用下获得能量,叶轮林槽道内的水在离心力的作用下甩向外围流进泵壳,于是在叶轮中心压力降低,这个压力低于进水管压力,水就在这个压力差的作用下由吸水池流入叶轮,这样水泵就可以不断的吸水,不断的供水了。
具有结构简单、不易磨损,运行平稳、噪声小、出水均匀,可以制造各种参数的水泵,效率高等优点,因此离心泵可以广大的应用。
凝结水泵轴封有良好的密封性能,不允许发生漏泄现象。
凝结水泵轴封采用机械密封。
泵能在出口阀关闭的情况下启动,而后开启出口阀门。
泵能承受短时间的反转。
2 凝结水精处理装置为确保锅炉给水品质,防止由于铜管泄漏或其它原因造成凝结水中的含盐量增大。
(大机组特有)。
3 轴封加热器及凝结水最小流量再循环在汽轮机级内,主要是在隔板和主轴的间隙处,以及动叶顶部与汽缸(或隔板套)的间隙处存在漏汽。
