*Required filter sizes shown are based on the larger of the ARI (Air conditioning and Refrigeration Institute) rated cooling airflow or the heating airflow velocity of
300 ft/minute for throwaway type or 450 ft/minute for high---capacity type. Air filter pressure drop for non---standard filters must not exceed 0.08 in. wc.

ROUTING POWER LEADS INTO UNIT
Use only copper wire between disconnect and unit. The
highvoltage leads should be in a conduit until they enter the duct
panel; conduit termination at the duct panel must be watertight.
Run the high--voltage leads through the power entry knockout on
the power entry side panel. (See Fig. 2 and 3 for location and
size) When the leads are inside the unit, run leads up the
high--voltage raceway to the line wiring splice box (See Fig. 12
through 16). For singlephase units, connect leads to the black and
yellow wires; for 3--phase units, connect the leads to the black,
yellow, and blue wires.
CONNECTING GROUND LEAD TO GROUND LUG
Refer to Fig. 14 and 15. Connect the ground lead to the chassis
using the ground lug in the wiring splice box.
ROUTING CONTROL POWER WIRES (24--V)
Form a drip--loop with the thermostat leads before routing them
into the unit. Route the thermostat leads through grommeted,
low--voltage hole provided in unit into unit control power splice
box. (See Fig. 2 and 3) Connect thermostat leads to unit control
power leads as shown in Fig. 14.
The unit transformer supplies 24--v power for complete system
including accessory electrical heater. An manual reset circuit
breaker (See Fig. 16) is provided in the 24--v circuit (See Fig. 17).
Transformer is factory wired for 230--v operation. If supply
voltage is 208--v, rewire transformer primary as described in
Special Procedures for 208--v Operation section.
EASY SELECT
t
-- 604D
EASY SELECT CONFIGURATION TAPS FOR 604D
Easy Select taps are used by the installer to configure a system.
The ECM motor uses the selected taps to modify its operation to
a pre--programmed table of airflows. The unit must be configured
to operate properly with system components with which it is
installed. To successfully configure a basic system (see
information printed on circuit board label located next to select
pins), move the 6 select wires to the pins which match the
components used.
a. AUX HEAT kW/CFM--SELECT HEATER RANGE
FOR SIZE OF ELECTRIC HEATER INSTALLED
Installer must select the auxiliary heat airflow
approved for application with kW size heater installed.
If no heater is installed, this step can be skipped. Each
select pin is marked with a range of heaters for which
airflow (also marked), is approved. For increased
comfort, select the narrowest kW range matching the
heater size, for example, 0--10 for 10--kW heater. This
airflow must be greater than the minimum for CFM
for electric heater application with the size system
installed for safe and continuous operation. (See Tables
3, 4, 5, 6 & 7 for airflow delivery and minimum
CFM.) Note that airflow marked is the airflow which
will be supplied in emergency heat mode and heating
mode on air conditioners when electric heat is the
primary heating source. In heat pump heating mode
when electric heaters are energized, the ECM will run
the higher of heat pump heating airflow and electric
heater airflow to ensure safe heater operation. The
factory selection is the largest heater range approved
(See Fig. 18, A as indicated).
