Electrical wiring and connections should be made by a qualified electrician in accordance with all national and
local electrical codes. Check all system specifications provided in this manual when working on the

14.2 Rotation Check
Always turn on (bump) starter and run motor very briefly to check for proper
direction of rotation. A sticker (Figure 33) indicates proper rotation direction. A
directional arrow is also stamped into the fan cover.
Operation in reverse direction for extended periods of time will cause a reciprocating compressor to
run hot and perform poorly and may cause permanent damage.
