SPECIFICATIONS (1)
Model: M1-15AF![]()
Specification Notes:
1. Since product innovation and improvement is our constant goal, all features and specifications are subject to change without notice or liabililty.
Selection of certain optional features may change listed specifications.
2. 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.
3. Design ambient conditions. Loss of capacity and/or difficulty operating will occur at higher ambients. Minimum recommended ambient is 60°F.
4. Full load amps are higher than run load amps and must be used for sizing disconnects and supply wiring.
5. Approximate unit weight crated for shipment.
6. See Warranty Statement #W-700 for details.
