9 Table 1 — P hysical D ata LEGEND *The ZRU140KC compressor is a tandem compre ssor , consisting of a ZR72K C (25% to tal capacity) and a ZR68KC (24% total capacity). †Circuit 1 uses the lower portion of the condenser coil and lower p or tion of the ev aporator coils; and Circuit 2 uses t he upper por tion of both coils .
10 Table 1 — Physical Data (cont) LEGEND *The ZRU140KC compressor is a tandem compre ssor , consisting of a ZR72K C (25% to tal capacity) and a Z R68KC (24% t otal capacity). †Circuit 1 uses the lower portion of the condenser coil and lower p or tion of the ev aporator coils; and Circuit 2 uses t he upper por tion of both coils .
11 Step 3 — Field F abricate Ductwor k — Secure all ducts to building structure. U se flexible duct c onnectors be- tween unit and ducts as required. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in acc ordance with applicable code s.
12 Step 7 — Orifice Change — This unit i s factory as- sembled for heating operation using natural gas at an elevation from sea level to 2000 ft. This unit uses orifice type LH32RFnnn, where “nnn” indicates the orifice size based on drill size diameter in thousands of an i nch.
13 Step 8 — Install Gas Pi ping — Unit is equipped for use with natural ga s. Installation must conform with l ocal building codes or , in the absence of l ocal codes, with t he National Fuel Gas Code, ANSI Z223.1. Install field-supplied m anual gas shutoff valve with a 1 / 8 -in.
14 OP TIONAL NON-F USED DISCONNEC T — On unit s with the optional non-fused disconnect, incoming power w ill be wired into the disconnect switch. Refer to Fig. 17 for wiring for 100 and 200 amp disconnect swi tches. Units with an MOCP (maximum overcurrent protect ion) under 100 will use the 100 amp disconnect switch.
15 Table 5 — E lectrical Data LEGEND *Fuse or HACR ci rcuit br eaker . NO TES: 1. In compliance with NEC r equirements for multimotor and combin ation load equ ipment ( refer to NEC Ar ti cles 430 a nd 440) , the overcurrent p ro- tective de vice for the unit shall be fuse or HA CR breaker .
16 Step 10 — Make Outdoor -Air Inlet Adjust- ments MANUAL OUTDOOR-AIR DAMPER — All un i ts (ex c ep t those equipped with a fac tory-installed economizer) ha ve a manual outdoor-air damper to provide ventilation air . Damper can be preset to admit up to 25% outdoor air into return-air compar tment.
17 Step 12 — Install All Accessori es — After all th e factory-installed opt ions have been adj usted, install all f ield- installed acc essories .
18 MOTORMASTER® V CONTROL INST ALLA TION (48TM025 On ly) Install Field-Fabricated W i nd Baffles — Wind baffles must be field-fabricated for a ll units to ensure prope r cooling cycl e operation at low ambi ent temperatures. See Fig. 22 for baffle details.

23 DIFFERENTIAL ENTHALPY CONTRO L (Fig. 30) — Differential enthalpy control requires both an enthalpy switch/ receiver (33CSENTHSW) and an e nthalpy sensor (33CSENTSEN). The enthalpy switch/ receiver i s mounted in the outdoor air inlet and calculates outdoor air e nthalpy .
24 The mode jumper should be set to M3 for 4 to 20 mA output. The factory test jumper should remain on OFF or the enthalpy sensor will not calculate enthalpy . ENTH ALP Y SENS ORS AN D CONT ROL — T he en t ha lpy control (HH57AC077) is suppl ied as a field-installed accessory to be used w ith the EconoMi$er2 damper control option.

27 ECONOMI$ERIV CONTROL MOD ES Determine the EconoMi$erIV c ontrol mode before set up of the control. Some modes of operation may requi re different sen- sors.
28 Outdoor Enthal py Changeover — F or enthalpy control, ac - cessory enthalpy sensor (part number H H57AC078) is required. Replace the standard out door dry bulb temperatur e sensor with the accessory enthalpy sensor in the same mount- ing location.
29 T ypically the maximum ventilation rate will be about 5 to 10% more than the typica l cfm required per person, using normal outside air desi gn criteria.
30 In order to have the CO 2 sensor control the ec onomizer damper in this manner, first determine the damper voltage out- put for minimum or base ventilation. Base ventilation is the ventilation require d to remove cont aminants duri ng unoccu- pied periods.
