Introduction

This manual provides general information about the "C"
vintage Daikin RoofPak applied rooftop unit, models RPS,
RDT, RFS and RCS. In addition to an overall description of
the unit, it includes mechanical and electrical installation
procedures, commissioning procedures, sequence of operation
information, and maintenance instructions. For further
information on the optional forced draft gas-fired furnace,
refer to Bulletin No. IM 684 or IM 685.
The MicroTech II applied rooftop unit controller is available
on "C" vintage applied rooftop units. For a detailed description
of the MicroTech II components, input/output configurations,
field wiring options and requirements, and service procedures,
see IM 696. For operation and information on using and
programming the MicroTech II unit controller, refer to the
appropriate operation manual (see Table 1).
For a description of operation and information on using the
keypad to view data and set parameters, refer to the
appropriate program-specific operation manual (see Table 1)
