10 Tabl e 2 — El ectrical D ata (co nt) LEG END *Heater capacity (kW) is based on heater v oltage of 208 v , 240 v , 380 v , 480 v , and 575 v . Heaters are rated at 240 v , 380 v , 480 v , or 600 v . If power distribution v olt age to unit v aries from rated heater v oltage, heater kW wil l v ar y accordingly .
11 OP TIONAL N ON-FUSED DIS CONNECT — On unit s with the optional non-fused disconnect, incoming power w ill be wired into the disconnect switch. Refer to Fig. 13 for wiring for 100 and 200 amp disconnect switches. Units with an MOCP under 100 wi ll use the 100 a mp disconnect switch.
12 Table 3 — Heat Anticipator Settings *Heater kW is based on heater voltage of 208 v , 240 v , 380 v , 480 v , and 575 v . Step 8 — Install Outdoor - Air Hood — The sa me type of factory-installed hood is used on units with 25% air ventilation and units wit h an EconoMi$er .
13 CO M M I S SI O N I NG — The EconoMi$er saves energy when it uses outdoor air to provide free cooling instead of mechani- cal air conditioning. The EconoMi$er switchover strategy de- termines if the outdoor air is suitable for free cooling.
14 MECHANICAL COOLING LOCKOUT — D e t e rm i ne th e outdoor-air temperature at which you want the mechanical cooling (compressors) to be disabled. Locate the mechanical cooling lockout (MECH CLG LOCKOUT ) pot entiometer . T o disable this feature, turn the potentiometer countercl ockwise (CCW) to the OFF position.
15 VENTILA TION AIR (Mini mum Positio n Set Up) — If ven- tilation air is not required, skip this section. If ventilation air is required, perform the fol lowing: 1. The indoor fan must be on to set th e ventilation air . Either put the thermostat in the continuo us fan mode or jumper the R and G terminals at the rooftop u nit con- nection board.
16 Install Motormaster I Co ntro ls — Only on e Mo torma ster I control is required per unit. The Motormaster I control must be used in conjunction with the Access ory 0° F Low Ambient Kit (purchased separately). The Mot ormaster I device controls out- door fan no.

22 Table 11 — Accesso ry/FIOP Static Pressur e (in. w g) — 50T J016 LEG END NOTES: 1. T he static pressur e must be added to external static pr essure. The sum and the e v aporator entering-air cfm should then be used in conjunction with the F an P erf ormance tables to deter- mine blo wer rpm and watts.
23 Base Unit Operation COOL ING, UNIT S WIT HOUT E CONOM I$E R — W h en thermostat cal ls for cooli ng, terminals G and Y1 are e nergized. The indoor (evaporator) fan contactor (IFC), and compressor contactor no. 1 (C1) are energized and eva porator-fan motor, compressor no.
24 When t he h umidi stat is s atisf ied, th e hu midis tat inte rnal switch opens, cutting power t o and deenergizing the LLSVs. The refrigerant i s routed back through the evaporators and t he sub-cooler coils are r emoved from the refrige rant loops.
25 the inlet of the compressor . The compressor should then be run for 10 minutes, shut down, a nd the acce ss valve ope ned until no oil flows. This should be repeated twice to ma ke sure the proper oil level has been achie ved. F A N SH A F T B EA RI N GS — For size 016 units, bearings ar e permanently lubricated .
26 Belt T ension Adjustment — T o adjust belt tension: 1. Loosen fan motor bolts. 2. Adjus t be lt te nsio n: a. Size 016 Units: Move motor mounting plate up or down for proper belt tension ( 1 / 2 in.
27 EconoMi$er Adjustment LE D I ND IC A TI O N — The EconoMi$er controller features an onboard diagnostic LED (light-emitting diode) that flashes to indicate its status. See T able 15 for flash codes. The c ontrol- ler also has terminal connec tions (REM LED) for rem otely mounting an LED, if desired.
