Installation/Operating Instructions
AeroLift 25 by Draper
Hanging Unit
The AeroLift 25 is provided with four (4) mounting angles for suspending or direct
mounting the unit from above or direct mounting from the sides. These angles
provide up to 1½" of adjustment (front to back). The AeroLift 25 is designed to fit
between joists spaced 16" apart on center (assuming 2" joists), and to close to
aproximately 4", not including the projector, bracket or closure. The unit should
be guy wired or blocked to prevent swinging. All installations should observe the
following guidelines:
1 Installer must ensure that all fasteners and supports are of adequate strength to
securely support AeroLift 25 and projector. It is recommended that hardware
structure be able to hold at least four times the combined weight of the lift,
projector, housing, closure and ceiling material attached to closure.
Caution: DO NOT hang from, "ride" or pull down on the unit.
This could create a failure and cause damage and/or injury.
2 Fastening methods must be suitable for mounting surface, and securely
anchored so that vibration or abusive pulling on unit will not weaken installation.
3 Bottom of unit must be unobstructed after installation. Sufficient clearance must
be allowed below projector or optional ceiling closure.
4 Do not use unit to support adjacent ceiling, light fixtures, etc.
5 Do not complete the ceiling below unit until electrical connections have been
completed and unit has been operated successfully.
6 Use slots on the projector plate and on the closure to adjust the unit to ensure
proper alignment of ceiling closure relative to ceiling opening.
Electrical Connections
Unit operates on 110-120V AC, 60 Hz. current.
The AeroLift 25 is shipped closed, with a temporary field connection provided in
the form of a pigtail temporarily wired to the unit. After hanging the unit, make sure
power is off and use this pigtail to temporarily connect the unit to power and to a
switch, so the unit can be lowered to allow access inside.
AeroLift must be installed in accordance with the requirements of the Local
Building Codes, the Canadian Electrical Code (CEC), CAN/CSA C22.1 and the
National Electric Code(NEC), NFPA 70. All operating switches should be “off”
before power is connected.
Caution:
1 Read instructions completely before proceeding.
2 Follow instructions carefully. Installation contrary to instructions invalidates
warranty.
3 Do not obstruct operation of AeroLift 25 with fingers or any object. Serious
injury or damage could result.
4 It is not uncommon to overheat the motor during initial installation when set-
ting limits. The motor is thermally protected and will stop working temporarily.
DO NOT physically pull the unit down when this occurs. Once it has cooled
to a safe temperature, it will begin operating again.
5 The AeroLift 25 is designed to accommodate ceiling suspended equipment.
Equipment should not be allowed to rest on ceiling closure during operation.
(Refer to section titled “Installing Projector.”)
6 Entire bottom of unit must be unobstructed to permit proper operation.
7 Unit must be installed level (use a carpenter’s level).
8 Unit operates on 110-120V AC 60 Hz. current.
Note: Unit has been thoroughly inspected and tested at factory and found to be
operating properly prior to shipment.
Please note: Make sure electrical supply has been disconnected before
attempting to connect AeroLift 25 to electricity.
Terminal strip for field connections is located inside a junction box on the end
of the unit. Unit is shipped with internal wiring complete to the terminal strip.
Once the unit has been lowered, turn off power and remove the J-box cover. The
terminal strip is attached to the cover. Disconnect temporary pigtail from unit, then
complete permanent wiring to electricity and to switches. Wire to connect unit to
power supply and to switches should be furnished by installer. Connections should
be made in accordance with wiring diagram. AeroLift 25 should be operated and
checked prior to installing projector and/or optional ceiling closure.
Operation
When unit is first operated, be cautious! If unit fails to operate when the switch
is flipped “down”, return switch to “off” and recheck electrical connections
before proceeding. Cycle unit down and up several times to confirm satisfactory
operation.
110-120V Single Station Control — 3-position up-off-down switch permits
operation to be stopped at any point. Factory adjusted limit switches automatically
stop AeroLift 25 when fully down or fully up.
Optional 110-120V Multiple Station Control—Switches are similar in
appearance to 110-120V Single Station Control. AeroLift 25 stops when switch is
released and may be restarted in either direction. Factory adjusted limit switches
automatically stop AeroLift 25 when up or fully down.
Optional 24V Control — Three-button up-stop-down switches stop at any point
desired, operate in any sequence. Factory adjusted limit switches automatically
stop AeroLift 25 when fully up or fully down.
Optional Infrared or Radio Frequency Remote Control—If ordered, a three-
button transmitter is provided, with “up”, “down”, and “stop” buttons. Unit starts up
or down when appropriate button is pressed, and may be stopped by pressing
“off” button. Factory set limit switches stop unit automatically when projector is in
“show” position.
Optional RS232/Ethernet—Serial communication and network communication
optionally available with wall switches, RF or IR remote.
Optional Key Operated Switching — Two kinds of key-operated switches
are optionally available with this unit. 1 The key-operated power supply switch
controls power to the AeroLift 25 and switches. When it is “off”, the switches will
not operate lift. Key may be removed from the switch in either “on” or “off” position.
2 A three-position key switch permits the AeroLift 25 to be operated directly by
key. In this case, the screen’s operator must always have a key.
If you encounter any difficulties installing or servicing your AeroLift 25, call your
dealer or Draper, Inc. in Spiceland, Indiana, 765-987-7999, or fax [phone].
AeroLift 25 Mounting Hole Dimensions
Please Note: As weight is applied to the AeroLift 25, the projector plate may
shift slightly. If this occurs, use setscrews on bottom of fabric roller brackets
to compensate for shift and level projector plate.

Testing the Safety Limit Switches
The AeroLift 25 is equipped with a Safety Limit Switch (see "AeroLift 25—Limit
Switch Adjustment (Bottom View)" diagram on page 3). This switch may be dam
-
aged during shipping or by rough handling on the job site. Once the AeroLift 25
has been installed in the ceiling, but before the projector and closure are attached,
the Safety Limit must be tested. Use a screwdriver or other tool to press and
hold the switch. While holding down the switch, have someone operate the unit. If
the unit works while the switch is depressed, the limit switch is broken and
must be replaced. Operating the unit without a functioning Safety Limit Switch
could cause the unit's motor to continue operating after the lift is closed, leading to
a failure and the possibility of damage or injury.
