Disassembly of Sections
If units are ordered for modular construction, they may be
easily disassembled into three sections. The figures below
illustrate the main cooling/heating, filter/waterside econo-
mizer, and fan sections. The thick lines in the figures show
where the sections are disassembled. The section are secured
by connection plates and screws. The following information
describes the location of the connecting points.
Fan section — base sections disassembly
The fan section sits on the base sections and is secured with
four steel plates. Each plate has two screws in the base sec-
tions and two screws in the fan section. Two of the plates are
shown in Figure 3. The connection plates are also the rigging
plates for the fan section only. They must not be used for rig-
ging the entire unit.
Main cooling/heating — filter/waterside economizer
sections disassembly
The following information is for units ordered for modular
construction (code 32=1). Note: The disassembly of units
not ordered for modular construction (code 32=Y) will
require field modification. Units not ordered for modular
construction do not have victaulic couplings on the water
pipes and the various control sensors are mounted in the unit.
●
Two steel plates the height of the sections connect the
main cooling/heating and the filter/waterside econo-
mizer sections. The plates are secured with multiple
screws on the right and left side of the base sections.
The connection plate and screws are illustrated in Sect
A-A.
●
The filter/waterside economizer section overlaps the
main cooling/heating sections along the bottom and top
adjoining rails. Multiple screws connect the two sec-
tions along these bottom and top overlaps.
●
Victaulic couplings connect the water pipes between the
filter/waterside and main cooling/heating sections. Each
victaulic coupling is secured with two bolts
●
.The condensate drain pipe between the two sections is
connected by a flexible PVC tube with pipe clamps.
