Installation Instructions
[] INSTALL THE DRAIN
An external or an internal chain must
|xe attached
to
the ch"ain connector.
External Drain
Attach a 90 ° PV(: elbow to tile unit's fbmale 3/4" NPI'
drain connectol: Lse the other end of the dbow to
1/111 a 3/4" Sch.40 PVC pipe through the knockout
holes ot both the wall plmmm and the archimctural
louver 1o the outside. Seal the gap between th_
plenum hole and PVC ulbe. S_e the Installation

[] DUCTWORK
Prepare
tile closet ductwork {be later connection to
the case.
The total flow role (CF*[) and exlernal static pres,,ure
(ESP) awilable can be esthnamd from tile chart below.
[ 7s*! t hese charts to select x_mr thn speed setting. Th_
,v
collar on top of th_ ca_ a(cepts standaM 10 duct.
Pull all duct tight. Extra duct slack can gl>atly increase
slatic pressur(.
CAUTION: Flex duct can collapse and cause airflow
re_tricfion_ Do not rtse flex duct for 90 ° bends or
unsupported runs of 5 fL or more.

Y*_ur airflow should be balanc(d based on many
thctors, such as available ESP, room CFM, and
ductwork. Consuh all I l_:\C engineer
fi'w proper
applications. External static pressure
(ESP)
can be
measm-ed with a manolneter or pitot tube. Once this
ESP is esta])lished, }ou can calculate tile CFM using
tile above chalt.
