The larger system capacities (ESP-4860D) are effected
more by higher system static pressure than the smaller
systems. The four and five ton system should be
considered and handled as two separate smaller units.
Installation of the plenum tee closer than the minimum
indicated in Fig. 1.3 will reduce performance of the
system. No supply runs should be installed between unit
outlet and this tee. Static readings on system should be
taken before tee.
Supply Tubing
In the case of two-story or split-level applications, supply
tubing may run from one story to another. It is small
enough to go in stud spaces, but this is often difficult in
older homes because of hidden obstructions in stud
spaces. It is more common to run the supply tubing from
the attic down through second story closets to the first
story terminators.
Supply tubing runs in the corners of the second story
rooms can be boxed in and are hardly noticeable since
overall diameter is only 3
1
⁄
4
".
Room Terminators
Terminators should be located only in the ceiling or floor
for vertical discharge. Horizontal discharge is acceptable,
but is sometimes more difficult to install. Two excellent
spots for horizontal discharge are in the soffit area above
kitchen cabinets (see Figure 1.4) and in the top portion
of closets (see Figure 1.5).
Terminators should always be out of normal traffic
patterns to prevent discharge air from blowing directly on
occupants. And they should not be located directly above
shelves or large pieces of furniture. Outside wall or
corner locations are recommended if the room has more
than one outside wall. Locating terminators away from
interior doors prevents short cycling of air to the return air
box.
