York Predator ZH, ZJ and ZR (Sun Pro)
York's ZH, ZJ and ZR packaged rooftops, 3 to 12.5 tons, sold as Sun Pro from 2020 and as Predator before that. They share the 18-character model number with the ZF, so it tells you efficiency line, tonnage, heat type and size, blower, voltage, economizer, controls and generation.
Packaged rooftop: cooling only, gas heat or electric heat, with a reheat version · 3–12.5 tons · R-410A

- Age from the serial number
We haven’t found a York (Johnson Controls) document that explains how to date this family’s serial number, so we don’t decode it. Other ways to tell a rooftop unit’s age

Notes and limits
- Covers ZH, ZJ and ZR units, sizes 037–150 (3–12.5 tons), in the 18-character model number. ZH is the standard-efficiency line at 3–5 tons and the high-efficiency line at 6.5–12.5 tons; it is not a heat pump. ZJ is high efficiency; ZR is standard efficiency with reheat.
- The January 2020 guide (Rev. O) covers all three lines and product generations 1 and 2. The June 2020 revision (Rev. Q) drops ZH and the single-stage gas heat types and adds generation 3 for ZJ and ZR.
- Single-stage gas heat (heat type H, J, K or L) is shown only on the 3–5 ton physical data; 2-stage gas (N, S, P or Q) runs across all sizes. The heat type (digit 6) and heat size (digits 7–8) are decoded together because the same size code means gas input for gas heat and kilowatts for electric heat.
- Filters are the factory 2 in. throwaway filters (MERV 3) from the physical data tables. The optional 2 in. pleated MERV 8 filters are the same size; the optional 4 in. pleated MERV 13 filters have the same face size, 4 in. deep. At 6.5 and 7.5 tons the ZJ takes 24 x 20 filters while the ZH and ZR take 24 x 16. Confirm against the rack in the unit.
- Older Predator ZH, ZJ and ZR units (for example York's 2014 seventh-generation technical guide, 528150-YTG-V-1014) use a different 19-character model number with the gas heat code given as output MBH and an airflow code in position 9. If the heat code reads N10, N15, N20, S10, S15, S20 or starts with A or B (for example A07), you are looking at that older format: this decoder does not cover it and the positions after the heat code will not line up.
- York's sample model on the nomenclature page shows A in the blower position, which its blower table does not list; the example here uses B (standard static).
- The 15–25 ton ZJ and ZR Series 20 units (sizes 180–300) use a different York document and are not decoded here. Neither are the York Sun Core ZX, ZY, ZQ and ZL lines.
- No serial-number date decoder: we found no York or Johnson Controls document that states the serial format for these units.
