Option 1: Plumbing to drain with
condensate pump.
• Use Hartell A3X-115 condensate pump or equivalent
(212°F temperature rating, > 1 GPM pump flow rate).
• Pump must be powered when TrueSTEAM is operating.
• Use a pump with a built-in overflow sensor or install the pump
in a drip pan with wet switch wired to turn off TrueSTEAM.
• Support rubber hose every 6 in.
• PVC must be schedule 40 or higher rating.
• All plastic pipe joints are welded.
• Drain into a P-trap that will remain wetted at all times.
