Panels and Doors
Panel Removal
Destiny air handlers have pocket pull handles in alternate
sections that allow side panels to be easily removed and
handled. To gain access through a side panel, remove the
fasteners along the sides of the panel and lift the panel off
using the pocket pull handle. If the panel you are accessing
does not have a pocket pull handle, remove an adjoining panel
with a pocket pull handle and push the panel out from inside
the unit.

Fan Section Doors
1 Use a flat head screwdriver and rotate the screw 1/4 turn
as shown in Figure 6.
2 Rotate door handle 1/4 turn and open the door.

Actuators
The factory-mounted actuator has been initially adjusted in the
factory. Power and control wiring, as well as fine-tuning
adjustment, is to be performed in the field.
The installing contractor is responsible for the mounting of all
field-installed actuators. An actuator mounting plate is
provided on the shaft side of the damper frame to
accommodate many actuators. However, due to the number of
options, size variations, and arrangements available, some
actuators may require alternate field provided mounting
hardware. Provide proper support for the actuator to avoid
excessive stress in the cabinet, linkage, or damper shafts.
Fresh air and return air dampers can be linked together and
driven from the same actuator if the dampers are the same size.
If the dampers are different sizes, they must be driven by
separate actuators and controlled appropriately.
A typical rotary electric actuator can handle up to 40 square
feet of damper. For pneumatic actuators, allow 5 in.-lb. per
square foot of damper area.
DANGER
Hazardous moving parts, high static pressure, and/or high
voltage. Can cause severe injury or death.
Disconnect and lock ALL electric power off before entering or
servicing unit. Unit may employ multiple power supplies and/or
remote disconnects.
Secure drive sheaves to prevent motors and fan from free
wheeling.
When leaving the unit, use screw or door handle locking
mechanism provided to secure access panel closed and
prevent unintentional entry.
DANGER
Pieces mobiles dangereuses, haute pression statique et/ou
de hautes tensions. Risques de blessures graves, voire
mortelles.
Débranchez et verrouillez toutes les alimentation électriques
avant de pénétrer ou d’intervenir sur cet appareil. Cet appareil
peut étre alimenté par plusieurs sources etlou par
l’intermédiaire de plusieurs disjoncteurs éloignés.
Attachez les disques d’entrainement afin d’éviter que les
moteurs et le ventilateur ne tournent librement.
A Ia sortie de l’appareil, fermer le panneau d’accès avec Ia vis
ou avec le mécanisme de verrouillage de Ia poignée de porte
qui sont founis pour éviter toute entrée inopinée.
CAUTION
Maximum damper rotation is 70°. Maximum shaft torque is 205
in.-lb. Greater rotation or torque can cause equipment damage.
ATTENTION
La rotation maimale des volets est de 70°. Le couple (torque)
maximum de l’arbre est de 205 in./lb. Une plus grande rotation
(ou torque) peut endommager l’équipement.
