Series Installation Type
Many installations of these fixtures are in continuous rows. The ML series is
unique in that it is designed to be used in this manner though it is standard as
an individual fixture. Kurtzon provides a layout guide to facilitate the planning and installation of CRM option fixtures. See facing page.

ML-F Operating Room Planning and Layout Guide
ML04
1. Layout
This guide is provided in order to help our users plan proper
installation of the complete Surgical lighting system.
The electrical plans contain information required to determine the configuration and quantity of each system component. Please provide the plan or complete this information
sheet and return it to the Kurtzon Customer Service Department.
There are three pieces of information needed before production of your order.
ML-F Series fixtures are designed to join together without
overlapping flanges and seams. For example; the end fixtures are flanged on one end and two sides; middle fixtures
are flanged on two sides. The complete housing is hole free,
silicone sealed and mates with adjoining housings using a
multi-point fastening and gasket system. This method creates
a sealed plenum.
The layouts below are the most common found within surgical suites. Please indicate which layout is used within your
plans. If a different design is required or none at all, please
specify your layout by sending us ceiling plan drawings or
sketches of your requirements. To assist you in your planning
we provide cad drawings from our website. This allows the
user to assemble nearly any layout selecting from eight different flange arrangements.

2. Electrical
The electrical plans will indicate the number and configuration
of circuits controlling the fixture. A RFI filter is required per
switched circuit to comply with Mil Std. 461e. Please address
the following:
accommodate up to two circuits and a high lumen emergency
lighting ballast.
B. Emergency Lighting
Maintaining safe lighting levels in the surgical suite during a
power outage is possible using a self contained battery powered
emergency lighting ballast. Emergency lighting ballasts are
available in two general types. Standard NFPA 101 egress
lighting type and generator backup type. The two differ in the
amount of light generated and running time. The generator
backup type can drive up to three lamps at nearly full output
for a short duration, usually less than five minutes. Egress
lighting types will drive one or two lamps at a greatly reduced
output for 90 minutes. Please advise the type of emergency
lighting required for your project.
A. The number of switched circuits per fixture.
The standard fixture is provided with one switched circuit and
therefore one RFI. Additional switched circuits are specified
by the appropriate option suffix additions to the catalog number such as; 2/CIR or 3/CIR. Keep in mind; there is a physical limit to the number of ballasts RFI filters and emergency
lighting ballasts a fixture can contain. Our 2x4 fixture allows
up to four circuits or 3 circuits and one high lumen emergency
lighting ballast without modifications. Consult factory for
arrangements in excess of this. The smaller 2x2 fixture can

3. Ceiling Cutout
This series is intended for recessed installation in a plaster or
drywall (GWB) ceiling system. The sizing of the ceiling finished
opening or "cutout" is important to a successful installation. We
provide detailed drawings showing the ceiling cutout size with
each order. Also available are cad drawings showing examples
and templates in 2D and 3D on our website. If you still need
to calculate your own finished ceiling openings please consider
the following. The ceiling cutout is always spaced 0.50 inches
from the housing body. This gives proper spacing and tolerance
to create a cutout and seal the plenum. Cutouts are calculated
using the following formulas.
Row Cutout Formulas:
#1(L1 x Qty in Row) +1= CL
#2 W1 +1= CW

#4a. CL1 -2(W1)-2 = CW1 = 95*
#4b. CL2-2(W1)-2 = CW2 =49"*
When calculating the cutout for a rectangle with closed corners you must determine
the row length CL in both directions and offset the cutout by the result of W1+1 to
obtain result CW1 & CW2 dimension.
