Specification Notes:
1. Tons capacity at 12,000 BTU/ton per hour @ 50°F LWT @ 115°F condensing temperature. Capacities may be +/5% as reserved by
the compressor manufacturer. Capacity multipliers are 50°F - 1.00 ; 40°F - .80 ; 30°F - .60 ; 20°F - .40.
The minimum recommended operating temperature when no glycol is used is 48°F.
2. Consult pump curve for exact pump performance.
3. Selection of optional pumps for higher flow rates will raise the minimum recommended operating temperature when no glycol is used.
4. Full load amps are higher than run load amps and must be used for sizing disconnects and supply wiring. Not for construction. Consult factory for power requirements of unit as configured and on selected options.
5. PE = polyethylene; SS = stainless steel; MS = epoxy coated mild steel.
6. Approximate dimensions. Not for construction purposes.
7. See Warranty Statement #W-700 for details.
