RPS/RDT Factory Split at Condenser
Reassembly of Split Units
Although RoofPak units typically ship from the factory as
complete units, they may be split at the factory in one of three
possible configurations.
1. The RFS air handler section and RCS condenser section
ship as two separate units, each with its own power supply
and unit nameplate. This configuration is ordered when
the condenser is intended to remain remote from the air
handler because of space or structural constraints.
On all units except the RFS with end discharge, refriger-
ant piping is stubbed out the exterior of the cabinet for
convenient field piping between the RCS and RFS units,
and all necessary refrigeration components are provided.
2. The RPS/RDT unit factory split at the condenser ships as
an air handler section and a condenser section that will be
recoupled together on the roof. This configuration would
be ordered if a packaged RPS unit is desired, but cannot
go to the job site because of shipping length or weight
limitations. A single nameplate is attached to the air han-
dler section and power is fed to both sections through the
main control box, as it would be in a non-split RPS/RDT
unit.
All interconnecting piping and refrigeration components
are provided so that when the sections are coupled
together only field-provided couplings are required to
connect the piping.
3. The RPS/RDT unit factory split at the fan ships as two
pieces, split at the supply fan bulkhead, to be recoupled
together on the roof. Like the RPS/RDT unit factory split
at the condenser, this configuration would be ordered if
shipping length or weight limitation prevented a packaged
RPS/RDT from being ordered. Splitting at the fan has the
advantage of leaving all factory refrigerant piping intact
so field evacuation and charging is not required.
A single nameplate is attached to the air handler section
and power is fed to both sections through the main con-
trol box, as it would be in a non-split RPS/RDT unit.
