mounting bracket, optional ceiling closure and optional Environmental Air
Space Housing.
3 Arrange to provide service access to the unit.
4 Total maximum capacity of AeroLift 50 is 50 lbs.; capacity for AeroLift 150 is 150
lbs. (including closure, projector and bracket).
As Soon As AeroLift Arrives
1 Open carton and inspect for damage.
2 Locate the following parts:
A. The unit itself
B. Controls
C. Any optional equipment

Installation/Operating Instructions
AeroLift 50/150 by Draper
Hanging Unit
The AeroLift 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 (side to side). 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 50/150 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 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 the 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, 60 Hz. AC current. The AeroLift 50 and 150 are
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.
Please note: Make sure electrical supply has been disconnected before
attempting to connect AeroLift 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
Caution:
1 Read instructions completely before proceeding. Follow instructions carefully.
Installation contrary to instructions invalidates warranty.
2 Do not obstruct operation of AeroLift 50 or 150 with fingers or any other
object. Serious injury or damage could result.
3 It is not uncommon to overheat the motor during initial installation when
setting 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.
4 The AeroLift 50 and 150 are designed to accommodate ceiling suspended
equipment. Equipment should not be allowed to rest on ceiling closures
during operation (see “Installing Projector”).
5 Entire bottom of unit must be unobstructed to permit proper operation.
6 Unit must be installed level (use a carpenter’s level).
7 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.
to power supply and to switches should be furnished by installer. Connections
should be made in accordance with wiring diagram, and wiring should comply with
national and local electrical codes. All operating switches should be “off” before
power is connected. AeroLift 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 re-check 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 when fully down or fully up.
Optional 110-120V Multiple Station Control—Switches are similar in
appearance to 110-120V Single Station Control. AeroLift stops when switch is
released and may be restarted in either direction. Factory adjusted limit switches
automatically stop AeroLift 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 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. Multiple Station Control required for this option.
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 50 or 150, call
your dealer or Draper, Inc. in Spiceland, Indiana, 765-987-7999 or fax [phone].
AeroLift Mounting Hole Dimensions
Please Note: As weight is applied to the AeroLift, 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 (see page 3).

Testing the Safety Limit Switches
The AeroLift 50 and 150 are equipped with two Safety Limit Switches (see "Aero-
Lift—Limit Switch Adjustment (Bottom View)" diagram on page 3). These switches
may be damaged during shipping or by rough handling on the job site. Once the
AeroLift has been installed in the ceiling, but before the projector and closure are
attached, the Safety Limits must be tested. Use a screwdriver or other tool to
press and hold the limit switch. While holding down the limit switch, have someone
operate the unit. If the unit runs up while the limit switch is depressed, the
limit switch is broken and must be replaced. Operating the unit without a func
-
tioning 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. Make
sure to test BOTH switches.
