First Co WHSC Series Condensing Units - Manual (Page 2)

INSTALLING WHSC/WHHP
INTO SLEEVE
(1) After the sleeve is secured, install
the WHSC or WHHP unit into the
sleeve. Set the bottom edge of the
unit on the opening edge of the
sleeve. With the top of the unit
tilted slightly backwards, apply
primary force towards the bottom
of the unit while pushing forward
until the unit comes to a stop on
the sleeve face. The mounting
flange on the WHSC or WHHP
should then mate up flush with the
sleeve flange.
NOTE: Make sure isolation
grommets are installed on sleeve
flange (see. fig. 2).
(2) Before bolting the unit to the
sleeve apply a bead of silicone
sealant approved for exterior use
between the sleeve and the unit
top and both sides. The flange on
top of the unit may be temporarily
removed to facilitate ease of
applying sealant on top of unit.
(3) Using the 1/4" - 20 hex bolts and
washers, secure the unit at the
flange while the sealant is still
tacky.
NOTE: Check one last time for
complete seal around the unit and
sleeve and the sleeve and wall.
