NOTICE

I

NTRODUCTION

This booklet contains the installation and operating instruc-
tions for your modular blower cabinet.  All warnings and pre-
cautions within this booklet must be observed.  Improper in-
stallation can result in unsatisfactory operation or dangerous
conditions and void the warranty.  Read this booklet and any
instructions packaged with accessories prior to installation.
Give this booklet to the user and explain its provisions. The
user should retain this booklet for future reference.

NOTE:

 Upon start up in communicating mode the

 

circuit

board will display a “1 Flash” error code on the diagnostic
LED and an “Ec” HTR TO LARGE error at the communi-
cating display. This is an indication that the dip switches on
the control board need to be configured in accordance
with the Electric Heating Airflow Table on page 7 of this
manual. Configuring the dip switches and resetting power
to the unit will clear the error code.

RECAUTIONS

NOTE:

  Discharge body’s static electricity before touching

unit.  An electrostatic discharge can adversely affect electrical
components.

Use the following precautions during modular blower instal-
lation and servicing to protect the integrated control module
from damage.  By putting the modular blower, the control,
and the person at the same electrostatic potential, these steps
will help avoid exposing the integrated control module to elec-
trostatic discharge.  This procedure is applicable to both in-
stalled and uninstalled (ungrounded) blowers.

1. Disconnect all power to the blower.  Do not touch the

integrated control module or any wire connected to the
control prior to discharging your body’s electrostatic
charge to ground.

2. Firmly touch a clean, unpainted, metal surface of the

modular blower near the control.  Any tools held in a
person’s hand during grounding will be discharged.

3. Service integrated control module or connecting wiring

following the discharge process in step 2.  Use caution
not to recharge your body with static electricity; (i.e.,
do not move or shuffle your feet, do not touch
ungrounded objects, etc.).  If you come in contact with
an ungrounded object, repeat step 2 before touching
control or wires.

4. Discharge your body to ground before removing a new

control from its container.  Follow steps 1 through 3 if
installing the control on a blower.  Return any old or
new controls to their containers before touching any
ungrounded object.
