Unit Location heights Height at which unit heaters are installed is critical Maximum mounting heights for all units are listed in Table 4 1 and the height dimensions are shown in Figures 4 3 through 4 7 Maximum mounting heights for vertical models are given for units with or without optional air deflectors The data in Table 4 1 is based on operating conditions of 2 lbs steam or 220 F entering water with 60 F entering air When operating conditions are other than those above refer to Figure 4 2 for maximum mounting height correction factor To obtain the maximum mounting at actual operating conditions multiply the appropriate factor from Figure 4 2 by the mounting height in Table 4 1 The maximum mounting height for all units is that height above which the unit heater will not deliver heated air to the floor at standard rating conditions Figure 3 2 Deflector Mounting Unit Locations of Vertical Units In Narrow Buildings If an optional air deflector has been furnished for vertical units itis always shipped separately and can be attached to the unit before suspension Vertical louvers for horizontal units and horizontal louvers for Power Throw units can also be added and positioned before installation Cone jet and louver type deflectors must be attached with angle brackets and machine screws to the bottom cover of the unit Refer to mounting instructions which are furnished with each de

16. to catch dirt and scale the strainer should have a screen perforation size smaller than the trap orifices 6 Onsystems where the steam supply to the unit heater is modulated or controlled by a motorized valve a vacuum breaker should be installed between unit outlet and the trap If a vacuum breaker is used it should be in conjunction with a float and thermostatic trap 7 Install a scale pocket at bottom of unit heater to collect dirt and scale as shown in illustrations Pipe diameter must be the same size as unit connections and about six inches long 8 Provide adequate pipe hangers supports or anchors to secure the piping system independently of the unit heater Electrical Connections A WARNING Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage All appliances must be wired strictly in accordance with wiring diagram furnished with the appliance Any wiring different from the wiring diagram could result in a hazard to persons and property Any original factory wiring that requires replacement must be replaced with wiring material having a temperature rating of at least 105 C Ensure that the supply voltage to the appliance as indicated on the serial plate is not 5 greater than the rated voltage A CAUTION Do not install units below 8 feet measured from the bottom of the unit to the floor Do not reuse any electrical component which has been wet Such co
