6.0 CONDENSATE DRAIN TUBING
Consult local codes or ordinances for specific requirements that may apply.
• The coil door is shipped from the factory with the condensate drain knockout
attached. Knockout must be removed and the condensate block-off plate (included in
parts bag, see Figure 11) must be installed to access the front drain.
• Vertical units (vertical drain pan) are supplied with a 3/4” female pipe thread primary
drain connection and a 3/4” female pipe thread auxiliary drain connection. (See unit
dimensions figures for drain locations.)
IMPORTANT: Side drain connections on vertical drain pans have a plastic web
covering opening. Connection(s) used must be broken out before connection(s)
are made. Break out only connection(s) to be used. Front drain connections have
removable threaded plastic plugs factory installed. Plugs must be removed before
connections are made; do not remove plugs if these connections are not used.
• Horizontal units (horizontal drain pan) are supplied with a 3/4” female pipe thread pri-
mary drain connection and a 3/4” female pipe thread auxiliary drain connection. (See
unit dimensions and position figures for drain locations).
IMPORTANT: All horizontal pans have plastic web over the secondary drain con-
nection. Plastic web covering secondary connection must be broken out if used.
Secondary connection is lowered by 3/8”. Do not get primary and secondary con-
nections interchanged.
• Removal of door knockouts required for drain connections can be made much easier
with the door removed from the cabinet.
• Install drain lines so they do not block service access to front of unit. 24 in. clearance
is required for filter, coil or blower removal and service access.
• Make sure unit is level or pitched slightly toward primary drain connection so that
drain pan will drain completely without water standing in pan.
IMPORTANT: 2-6" PVC lengths are provided for making drain connection. When
making drain fitting connections to drain pan, use a thin layer of teflon paste, sili-
cone or teflon tape and install hand tight.
IMPORTANT: When making drain fitting connections to drain pan, do not over
torque. Overtorquing fittings can split pipe connections on drain pan.
• Do not reduce drain line size less than connection size provided on condensate drain
pan.
• All drain lines must be pitched downward away from the unit a minimum of 1/8 in. per
foot of line to ensure proper drainage.
• Do not connect condensate drain line to a closed or open sewer pipe. Run conden-
sate to an open drain or outdoors.
• The drain line should be insulated where necessary to prevent sweating and damage
due to condensate forming on the outside surface of the line.
