2.3.3 Housekeeping Pad Requirements
To ensure proper condensate drainage, the unit must be installed on a level concrete
“housekeeping” pad. The unit must be positioned on the pad such that the condensate
assembly is
not
located over the pad, as shown below.
The minimum thickness of the concrete pad depends on two factors:
•
Which CENTURION
model you’re installing
•
Whether the unit will connect to a Condensate Neutralizer tank.
The minimum pad thickness for installations
without
a Condensate Neutralizer tank is
4 to 8
inches
(10.2 to 20.3 cm)
If you are using the Condensate Neutralizer Tank (P/N
89030C
), you must ensure enough
height for the condensate to drain into the condensate trap, then into the neutralizer tank, and
then to the drain. This may require that a pit be dug for the Neutralizer Tank. For more
information on the Condensate Neutralizer Tank, see Technical Instruction Document TID-0074.
The following table specifies the minimum pit depth for the Condensate Neutralizer Tank (P/N
89030C
) if the unit is installed on a
4" pad
, and the pad height if the Neutralizer Tank must be
installed on the floor; note, in all cases a
6” pad
eliminates the need to a pit.
