Instruction manual

Units are equipped with primary and secondary 3/4-in. FPT drain connections. To prevent property damage and achieve optimum drainage
performance, BOTH primary and secondary drain lines should be installed and include properly sized condensate traps. Factory approved
condensate traps are available. It is recommended that PVC fittings be used on the plastic condensate pan. Finger-tighten plus 1-1/2 turns. Do not
over-tighten. Use Pipe dope.
CAUTION: Shallow, running traps are inadequate and DO NOT allow proper drainage. Failure to follow this CAUTION
could result in minor personal injury or product and property damage.
NOTE: When connecting condensate drain lines, avoid blocking filter access panel, thus preventing filter removal. After connection, prime both
primary and secondary condensate traps.
NOTE: If unit is located in or above a living space where damage may result from condensate overflow, a field-supplied, external condensate
pan should be installed underneath the entire unit, and a secondary, condensate line (with appropriate trap) should be run from the unit into the
pan. Any condensate in the external condensate pan should be drained to a noticeable place. As an alternative to using an external condensate pan,
some localities may allow the use of a separate 3/4-inch cndensate line (with appropriate trap) to a place where the condensate will be noticeable.
The owner of the structure must be informed that when condensate flows from the secondary drain or external condensate pan, the unit requires
servicing or water damage will occur.
Install traps in the condensate lines as close to the coil as possible. Make sure that the outlet of each trap is below its connection to the condensate
pan to prevent condensate from overflowing the drain pan. Prime all traps, test for leaks, and insulate traps if located above a living area.
Condensate drain lines should be pitched downward at a minimum of 1 in. for every 10 ft. of length.
Consult local codes for additional restricitons or precautions.
23. Reconnect liquid and vapor refrigerant lines and condensate drain line. Install filter drier(s) if necessary.
NOTE: If a torch is used to unbraze the line set, protect the fitting panel with a wet cloth or braze shield as necessary.
24. Evacuate line set and indoor coil.
25. Back seat (open) liquid and vapor service valves.
26. Turn on electrical supplies to indoor and outdoor units.
27. Check system refrigerant charge and operation. See Split-System Residential Air Conditioners and Heat Pump Service Manual for further
information.
