3. Complete the piping of the hydronic package, includ-
ing field supplied shut off valves and other field supplied
items.
4. Put the installer-supplied threaded rods through the
slots in the brackets
(Figure 6)
, Place a washer and nut
on the threaded rod, and tighten the nut to secure it in
place. The upper end of the threaded rod should be
secured to angle iron or 2” x 4” wood. Make sure that
the rods do not interfere with the chassis plenum or duct
work. These rods will hold the hydronic package in place
when the chassis is removed for maintenance.
IMPORTANT:
System duct work is connected to the
discharge opening on the duct collar or plenum. A flex
collar is advised.
HYDRONIC COIL OPTION
The coil package comes with a sheet metal enclosure.
An optional 2 or 3 way motorized 24V water valve is avail-
able. Verify that the hydronic coil package is either left, right
or front aligned, matching the control section alignment of
the unit on which it is to be installed.
1. The coil package is centered on top of the VPAC/
VPHP chassis. Make sure it is centered over the fan
discharge and that the piping package is in the correct
position.
2. Find the two “Z” brackets used to clamp the hydronic
enclosure to the chassis top. Mount these brackets to
the chassis top using the holes provided. This will allow
the chassis to be pulled out for service/maintenance
without disturbing the hydronic package.
