I − UNIT INFORMATION
HP29 units are available in 1 -1/2, 2, 2 -1/2, 3, 3 -1/2, 4 and 5
ton capacities.
All major components (indoor blower/coil) must be matched
according to Lennox recommendations for the compressor to
be covered under warranty. Refer to the Engineering
Handbook for approved system matchups. A misapplied
system will cause erratic operation and can result in early
compressor failure.
II − UNIT COMPONENTS
Unit components are illustrated in figure 2.
A − Control Box (Figures 3, 4 and 5)
Electrical openings are provided under the control box
cover. Field thermostat wiring is made to color-coded
pigtail connections as illustrated in figure 1.
