4.1 Installing P-traps on header drains

A condensate trap should be installed on the ¾" pipe connection provided
on the bottom of each header. The connection is ¾" male NPT for North
American markets and ¾" male Gas for other markets. Given the minimal
pressure inside the header, a P-trap is generally suitable for the header drains.
The fi ttings and pipe for the P-trap (shown in Fig.3.a) are not included with
the ultimateSAM distributor.
If P-traps are used on the drains, the seal height should be suffi cient such
that the water column creates a pressure at least 500 Pa (50 mm or 2" H2O)
greater than the static pressure in the header. (Refer to the design manual
for more information on static pressure of the header.) While a seal height
of 150mm (6") is adequate for most installations where the condensate trap
drains into a sump inside the duct, check the design manual for details on the
back pressure generated by distributor being installed.
NOTE: Check local requirements regarding the minimum recommended seal
height and drop height for the installation.

Note: The fi ttings and pipe for the condensate drain shown in Fig.7.c are not
included with the ultimateSAM distributor.
If the P-trap empties outside the duct or AHU as shown in Fig.3.a, the seal
height and drop height must allow for the static pressure inside the duct or
AHU in addition to the static pressure in the header. If the space limits the seal
height for the condensate drain, a diff erent type of trap, e.g., F&T trap could
be used, or a distributor having a lower backpressure could be selected.

4.2 Trap, strainer, and separator kits
for distributor inlets connected to
pressurized steam supplies
For installations in which the ultimateSAM distributor is supplied with
pressurized steam, a trap and strainer are required at the inlet of the control
valve. A variety of trap and strainer kits are available as accessories. (Fig.3.b)
