®
RTU, snap in
Category 5 plenum rated patch cables with RJ- 45 ends into the FFU
controller. It does not matter which RJ- 45 jack on the controller you go
into and out of. These whips follow a daisy-chain pattern with one whip
going into one RJ-45 and the other whip coming out of the other RJ-45
in each controller. Refer to the layout specific drawing for the job.
Control can be via an ACC console or the building management
system.
- ACC console: Refer to ACC Console section in the back of this
manual.
- Building Management System: For this option, all hardware,
gateways and software are supplied and installed by others. Refer to
the ACM1015 networking advanced manual in the back of this
manual.
FFU ON TOP-LOAD FILTER
For the FFU on top-load filter option, place filter onto grid with the
appropriate gel or gasket seal pre-applied to the grid members. Place
FFU atop filter. If latches are provided on the side of the FFU, clip those
on to the side of the filter extrusion.
FFU ON BOTTOM-LOAD FILTER
A. De-energize the electric circuit to the install area.
B. Follow the original filter manufacturer’s handling instructions at
all times. Do not rack or twist the filter frame or put pressure (even
hand pressure) on the filter media at any time. It is recommended
that two people handle each filter install and that lifts/jigs be used
where appropriate to facilitate a safe install.
C. Set DIP switches in the FFU and prepare the power flexible
connection.
D. For bottom load grid, prepare the upper area inside of the grid. Rotate
the clip tabs away to be next to the grid member so that the filter can
be pushed up as shown in Figure 1. The nut on the clip may need to
be loosened a bit to rotate the clip tab. Also remove the triangular
plates and two screws as indicated in Figure 3. The plates and screws
will be used for reinstall later.
E. Place the filter assembly on top of the FFU hoist. Make sure the filter
is seated correctly upon the hoist. There should be minimal movement when attempting the slide the filter while on the
hoist. The outer catches should be engaged and preventing the filter components from falling off of the lift. It is
important to make sure no part of the filter media is in contact with the hoist.
F. Inspect the gel in the filter channel to see that it is not damaged.
