Anexplanation of the alphanumeric identifi-cation code is provided below. Its usewill enable the owner/operator, install-ing contractors, and service engineersto define the Operation , specific compo-nents, and other options for any spe-cific ordering replacement parts orrequesting service, be sure to refer tothe specific model number and serialnumber printed on the unit InformationUnit NameplateA Mylar unit nameplate is located onthe unit s corner support next to the fil-ter access panel.

The acronym RTRM is usedextensively throughout this documentwhen referring to the control module through Proportional/Inte-gral control algorithms perform specificunit functions that governs unit opera-tion in response to; zone temperature,supply air temperature, and/or humid-ity conditions depending on the appli-cation. The stages of capacity controlfor these units are achieved by startingand stopping the RTRM is mounted in the controlpanel and is factory wired to the re-spective internal components.

8 TheRTRM receives and interprets informa-tion from other unit modules, sensors,remote panels, and customer binarycontacts to satisfy the applicable re-quest for Refrigerant!System contains oil and refrigerant under high pressure. Recover refrigerantto relieve pressure before opening the system. See unit nameplate for refrig-erant type. Do not use non-approved refrigerants, refrigerant substitutes, orrefrigerant to follow proper procedures or the use of non-approved refrigerants,refrigerant substitutes, or refrigerant additives could result in death or seri-ous injury or equipment Voltage w/Capacitors!Disconnect all electric power, including remote disconnects and discharge allmotor start/run capacitors before servicing. Follow proper lockout/tagout pro-cedures to ensure the power cannot be inadvertently energized. Verify with anappropriate voltmeter that all capacitors have discharged. Failure to discon-nect power and discharge capacitors before servicing could result in death orserious : For additional information regarding the safe discharge of capacitors,see PROD-SVB06A-EN or PROD-SVB06A-FRCAUTIONE quipment Damage From Ultraviolet (UV) Lights!

9 The manufacturer does not recommend field Installation of ultraviolet lights inits equipment for the intended purpose of improving indoor air quality. High in-tensity C-band ultraviolet light is known to severely damage polymer (plastic)materials and poses a personal safety risk to anyone exposed to the lightwithout proper personal protective equipment. Polymer materials commonlyfound in HVAC equipment that may be susceptible include insulation on elec-trical wiring, fan belts, thermal insulation, various fasteners and of these materials can result in serious damage to the manufacturer accepts no responsibility for the performance or operationof our equipment in which ultraviolet devices were installed outside of themanufacturer s factory or its approved InformationEconomizer Control ActuatorReliaTel ControlThe ECA monitors the mixed air tem-perature, return air temperature, mini-mum position setpoint (local or re-mote), power exhaust setpoint, CO2setpoint, CO2, and ambient dry bulb/enthalpy sensor or comparative humid-ity (return air humidity against ambienthumidity) sensors, if selected, to con-trol dampers to an accuracy of +/- 5%of stroke.
