Vlendo- <br />IF <br />Sffi� <br />REFRI GERA TION INSTALLA TION <br />After the RSC unit is in its final location and leveled, have a qualified refrigeration technician connect the <br />condensing unit to the RSC's refrigeration connection lines. <br />1) Utilizing proper refrigeration practices connect the refrigerant lineset to the RSC stub outs using long <br />radius fittings. Trim the line set length so as to keep from creating oil traps in the lines. <br />LINE PENETRATION AT 36 INCHES <br />2) Connect lineset to the remote mounted condensing unit. <br />3) Turn on power to the RSC to open liquid line solenoid, ALL brazing should be done under a low pressure <br />nitrogen purge. <br />4) After brazing, pressurize system with nitrogen and check brazed joints for leaks. <br />5) After leak checking, release the nitrogen and evacuate the system to 400 microns or below. Verify the <br />system holds this vacuum before weighing in the refrigerant charge. <br />6) Break vacuum with liquid refrigerant through the HIGH side access port at the condensing unit. <br />7) Turn power on to the condensing unit and continue charging through the LOW side port using a metering <br />device such as a "Quik Charge" or Uniweld's "Vapor Vue". Stop charging when sight glass clears and <br />check for required superheat of 10-12 degrees F. <br />8) Weigh in an additional two (2) pounds of refrigerant to insure proper sub cooling. <br />- Evaporator superheat 10 to 12°F. System operates with a controller set point and solenoid valve (pump <br />down). Condensing unit must have low pressure switch. <br />- 6 ft model: 11,800 BTU/hr, evaporating temp: 15°F @ 80°F dry bulb, 68°F wet bulb <br />- 3 & 4 ft models: 6,800 BTU/hr evaporating temp: 15°F @ 80°F dry bulb, 68°F wet bulb <br />20 <br />
