UNHv is supplied with two ½" I.D. flexible PvC hoses for
connection to copper or plastic condensate drain pipe work.
• Each drain line is labeled and plugged at the factory.
• Unplug appropriate line and connect to condensate
drain.
• Consider following information when installing UNHv:
A.
Install with highest point in condensate hose at
unit’s drain pan. Insures proper drainage.
B.
Slope condensate hose down in the direction of
water flow with minimum gradient of 1” (5mm) per
10’ (1m). There must not be any uphill gradients.
C.
When multiple units are connected to common
condensate drain, insure drain is large enough
to handle volume of condensate from all units.
Recommend having air vent in condensate hose to
prevent air locks.
D.
If using accessory condensate pump, follow pump
manufacturer instructions.
Use condensate hose tie downs in ceiling mount
applications.
