9. EXTERIOR GRILLE
Finish the sleeve exterior with a factory supplied
intake and discharge grille.
10. UNIT TO SLEEVE ATTACHMENT
Lift the unit and place it inside of the wall sleeve.
Then slide the unit forward until the unit contacts
the wall sleeve and makes a seal with the gasket
on the wall sleeve. Make sure unit is centered
inside of the wall sleeve.
The unit is secured to the wall sleeve using two
angles; use of the angles is optional and depends
on field installation conditions. The angles should
be placed on the both sides of the unit using pre-
punched holes to position them. They must be
installed before the unit is put into place.
after the unit is positioned screw the angles to the
front flange of the wall sleeve sides using two #10
x ½ inch self-drilling sheet metal screws on each
end. The required angles and screws are packed
inside the blower compartment of the unit.
11. CONDENSATE DRAIN PIPING
The condensate drain pan is fitted with a ¾” NPT
female pipe fitting which protrudes through the unit
wall sleeve bottom casing. The ¾” drain piping
should have drain trap installed to prevent condi-
tioned air from being blown out of the drain line.
The trap should be at least 2 inches deep with the
outlet a minimum of 1-½ inch below the inlet.
The drain piping on the outlet side of the trap
should be pitched ¼ inch per foot down towards
an open drain. unions should be installed between
the outlet side of the trap to allow for disconnecting
the piping and the trap for cleaning out.
12. HOT WATER PIPING – VPH UNITS ONLY
The vPH models are supplied with a 2 or 3-row
hot water heating coil. The water connections to
the heating coil project through the top of the unit
cabinet, adjacent to the supply air opening. The
orientation of the water in / water out through the
coil is interchangeable (either connection may be
the water in, without affecting heating output).
The maximum design entering water temperature
for these units is 200ºF.
The sweat connection stubs are 7/8” ID copper.
unions should be installed on both the inlet and
outlet piping (as close to the unit as possible), to
allow for disconnecting and removal of the entire
unit.
