b Pliant
These instructions are to be used in con­
junction with the basic instructions for the
Model 516 Fan Coil Unit. Section II of this
instruction describes the installation of the
electric duct heater package with other than
the Model 516 air handlers .
SECTION I
The electric duct heater is designed to be
used with the Models 18- and 24-516 Fan Coil
Units. Refer to Table I, Ratings and Capaci­
ties, for sizes and power inputs. Refer also
to the Dimensional Drawing.
The package, as shipped from the factory,
contains heater coils, a rating plate, a
sequencing relay (for 11- through 14,4-KW
size units), automatic temperature control,
and a manual temperature control switch.
Each heater has both sides of the power line
broken by a main contactor and a backup
contactor, and has an open set of contacts for
fan control.
Before Starting Installation:
1. Check local codes and ordinances for ad­
ditional requirements.
2. Check the incoming power supply to be
sure that the rated voltage, frequency, and
phase correspond to that stamped on the unit
ratirig plate.
3 . Check the building power supply to be sure
that it is sufficient to handle the additional
electrical load imposed by this equipment.
Installing the Electric Duct Heater Package
The duct heater package is designed for zero
clearance from combustible material. There
must be a 7 -1 /2 inch clearance in front of the
control box cover.
A collar for mounting the duct heater is pro­
vided with each Fan Coil Unit. Use this collar

if the heater is to be installed within 6 inches
downstream from the Fan Coil. Mount the
collar on the duct flanges of the Fan Coil so
that the opening for the duct heater is on the
same side of the Fan Coil as the coil con­
nections and rating plate. Make certain that
the flange is at the bottom of the duct heater
opening. This will insure that the heater is
placed at the correct depth.
Now, place the heater into the collar and
attach it to the collar with four sheet metal
screws.
If the application does not provide adequate
space for the duct heater to be installed
6 inches from the Fan Coil, then the duct
heater must be installed 48 inches down­
stream from the Fgyj-Coil Unit-.
