44 PRE-ST ART -UP Proceed as follows to inspect and prepa re the unit for initial start-up: 1. Remove all acces s panels. 2. Read and follow instructions on all W ARNING , CAU- TION, and INFORM A TIO N labels attached t o or shipped with unit. 3. Make the following inspections: a.
45 Heating — T o start the unit, turn on the main pow er supply . Set the thermostat at HEA T position at a setting above room temperature, the fan at AU TO position. The first stage of the thermostat energizes the indoor -fan motor , compressor , and out door fan; the second stage energizes electric heater el ements, if i nstalled.
46 • If SA T > SASP + 5 and economizer position >80% , economizer will go to m inimum positio n for 3 m inutes or until SA T > 6 8 F . • If compressor no. 1 is on then second stage of mechani- cal cooling will be ener gized. Other wise the first stage will be ener gized.
47 HEA T ING , U NIT WITH E CONOMI$ ER2, PRE MIERLINK ™ CO NTRO L AND A R OOM S ENS OR — Every 40 seconds the contro ller will calculat e the required heat stage s (maximum of 3) to maintain supply air t emperature (SA T) if the following qualifying conditions are met: • Indoor fan h as been on fo r at least 30 seconds.
48 FI L T E R S — C lean or repla ce at the st art of each hea ting and cooling season, or more often if operat ing conditions require it. Replacem ent filter s must be the same dime nsions as original filters. OUTDOOR-AIR INLET SCREEN — Cl e an t he s c re en wi th steam or hot water and a mild detergent.
