Planning
1 Based on screen location and projector specifications, determine proper
position for projector installation.
2 Confirm that there is adequate space for installation and operation.
Minimum clearance above ceiling level varies according to Micro Projector
Lift plus height of projector, optional projector mounting bracket, optional
ceiling closure, and optional environmental air space rated housing.
3 Arrange to provide service access to the unit.
As Soon As Micro Projector Lift 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
Micro Projector Lift by Draper
Hanging Unit
The Micro Projector Lift is provided with four (4) holes, spaced 18" apart
center to center (Fig 1), with
5
/ 16 " clinch nuts provided for suspending or direct
mounting the unit. 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 Micro Projector
Lift and projector.
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.
Electrical Connections
Unit operates on 110-120V AC, 60 Hz. current.
The Micro Projector Lift 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.
Caution: Make sure electrical supply has been disconnected before
attempting to connect MPL to electricity.
Junction box for field connections is located inside the unit on the left (as
seen from front, or non-scissored end). Unit is shipped with internal wiring
complete to the junction box. Once the unit has been lowered, turn off power,
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, and wiring should comply with national and
local electrical codes. All operating switches should be “off” before power is
connected.
Micro Projector Lift should be operated and checked prior to installing
projector and/or optional ceiling closure.
Caution:
1 Read instructions completely before proceeding.
2 Follow instructions carefully. Installation contrary to instructions invalidates
warranty.
3 Do not obstruct operation of Micro Projector Lift with fingers or any object.
Serious injury or damage could result.
4 It is not uncommon to overheat the motor during initial installation when
setting limits. The motor is thermally protected and will stop working until
it has cooled to a safe temperature before it will start operating again.
5 The Micro Projector Lift 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 Maximum lifting capacity 35 lbs.
9 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.
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.
110v Single Station Control — 3-position up-off-down switch permits
operation to be stopped at any point. Factory adjusted limit switches
automatically stop Micro Projector Lift when fully down or fully up.
Optional 110v Multiple Station Control—Switches are similar in
appearance to 110v Single Station Control. Micro Projector Lift stops when
switch is released and may be restarted in either direction. Factory adjusted
limit switches stop Micro Projector Lift automatically 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 Micro Projector Lift 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 MPL 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 MPL 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 Micro Projector Lift, call
your dealer or Draper, Inc. in Spiceland, Indiana, 765-987-7999, or fax [phone].
Please Note: MPL 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. An appropriate disconnect device shall
be provided as part of the building installation.

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 We recommend that safety cables be attached to the Micro Projector Lift for
added security (a sound installation practice with overhead equipment).
7 When the MPL is to be installed in “other space used for environmental
air” the optional environmental air space rated housing must be installed
per instructions to isolate the lift from the “other space used for
environmental air.”
