Section 2 -
Mounting Ropewalker to Building Structure
Please Note:
It is recommended that heavy items be hoisted up to the work area using appropriate machinery, i.e. hoisting lifts, block and tackle, etc.
When locating viewing surface and checking clearance for screen operation, remember surface is centered in the length of the case.
Regardless of mounting method used, the following points apply:
Section 4 -
Removing Shipping Bracket
1.
Remove the electrical access panel
(Section 3)
and locate the
shipping bracket
(shown in
RED
with hangtag, Fig. 3-A)
.
2.
Remove the shipping bracket from the shaft. Discard
(Fig. 3-B)
.
Section 3 -
Electrical Connections
Screen operates on 110-120V, 60 Hz., 7.5A; or 220-240V, 50 Hz., 3A current draw.
Junction box is just above the bottom access panel at the left end of screen lift.
1.
Screen should be lifted into position
ONLY
by end mounting brackets
or hoisting brackets. Keep case level by lifting both end plates at the
same time to prevent surface damage. Using more than one mounting
hole in each end plate ensures a much more stable installation.
NEVER
attempt to lift screen along its length or in the middle.
2.
Entire weight of unit
MUST BE
supported by end plates during
installation.
Please Note:
DO NOT
lift case at the center. Case leveling brackets
are
ONLY
used to reduce visible case deflection. Lift screen
ONLY
by
hoisting brackets. To ensure a safe installation, the entire weight of the
installed unit
MUST BE
supported by the mounting brackets.
3.
Screen should be positively and securely supported so that vibration or abusive
pulling will not weaken installation.
4.
Installer must ensure that fasteners used are of adequate strength and suitable
for mounting surface. Installer must also ensure that structure is of adequate
strength. Supporting hardware
(chains, cables, rods, etc.)
must be essentially vertical.
5.
Entire bottom of case must be readily accessible after installation is complete.
6.
Front, back, and top of case must be straight — not forced to warp or bow.
7.
Do not use case to support adjacent sections of ceiling.
8.
Do not seal unit in ceiling until electrical connections have been made and screen
has been operated successfully.
To access to the junction box
1.
Open left side access panel by removing two
(2)
screws from side of case
(Fig 2)
.
2.
Remove two
(2)
5/16
"
(8mm)
hex head screws that secure cover to junction box
to expose red, brown, black, and white pigtail leads and green ground wire
(see Sec. 5, Ropewalker Wiring)
.
3.
For optional low-voltage control, see Section 11.
4.
Screen lift is shipped with internal wiring complete and control switch
(es)
fully
boxed. Wire to connect screen to switch
(es)
and switch
(es)
to power supply
should be furnished by installer. Connections should be made in accordance
with attached wiring diagram, and wiring should comply with national and
local electrical codes.
CAUTION:
All operating switches should be "off" before connecting power.
