Manual 2100-665DPage 21 of 26module (CCM) also monitors the high pressure switch,and will allow one automatic retry (after soft lockoutdelay) before disabling the compressor in a hard lockout(requires manual reset). If hard lockout does occur,the ALR terminal on the CCM will become active with24V, which will power the high pressure relay within thewall-mount unit, breaking a digital input to the LC6000controller—signaling a high-pressure situation to thesystem.Pressure Service PortsHigh and low pressure service ports are installed onall units so that the system operating pressures can beobserved. A pressure table covering all models can befound on page 19. It is imperative to match the correctpressure table to the unit by model number.This unit employs high-flow Coremax valves instead ofthe typical Schrader type valves.WARNING! Do NOT use a Schrader valve core removaltool with these valves. Use of such a tool could resultin eye injuries or refrigerant burns!To change a Coremax valve without first removing therefrigerant, a special tool is required which can beobtained at www.fastestinc.com/en/SCCA07H. See thereplacement parts manual for replacement core partnumbers.Outdoor Fan MotorDue to design considerations of the condenser sectionof the wall-mount unit, placement/clearance of themotor/fan blade is critical to heat dispersal. Should achange of motor or fan blade be necessary, please viewFigure 23 for proper clearance adjustment.FIGURE 23Fan Blade Setting"A"AIRFLOWMIS-1724Model Dimension AW18A/W18LW24A/W24L 1.00"W30A/W30LW36A/W36L 1.25"W42A/W42LW48A/W48LW60A/W60LW72A/W72L1.75"
