61 T hermostat 2-P ipe T otal E le ctric H eat with V alve C on- trol — W ith this system, the complete heating requirement for the space is provided by the electric heater; the water system is never changed over for heating. It is therefore poss ible, just as with 4-pipe systems, to have heating or cooling at any time of the year .

66 Step 4 — Make Duct Connections — Install all ductwork to and from unit in accordance with all applicable codes. Duct construction must a llow unit to operate within duct external static pressure limits as shown on job submittals. Units designed to operate with ductwor k may be damaged if operated without intended ductwork attached.
67 Step 6 — Cut out Openings f or Grilles and Thermostats — On all units with optional supply-air or return-air grilles, dampers, thermostats, and switch plates, cut out openings where specified on the job plans. Be careful not to cut wires, piping or structural supports.
68 Standard motors are permanently sealed and lubricated. No lubrication is required unles s special motors have been supplied or unusual operating conditions exist. Clean Fa n Wheel — Lock open and tag unit electrical service switch. For access to fan assembly , remove front or bottom panel.
