Condensate Drain
The SH package unit is equipped with a 3/4" FPT cou- pling for condensate line connection. Plumbing must conform to local codes. Use a sealing compound on male pipe threads.
The condensate drain line must be properly trapped and routed to a suitable drain. See Figure 3 for proper
drain arrangement.The drain line must pitch to an open drain or pump to prevent clogging of the line. Seal around the drain connection with suitable material to prevent air leakage into the return air system.
