of this surgical lighting system. All operators and department heads

are urged to carefully review and become familiar with the warnings,

cautions and instructions contained herein. Your new surgical

lighting fixture features an advanced, state-of-the-art design, with

cool, shadow-reduced light and ease of maneuverability. It produces

light of a quality necessary for the most demanding and complex of

surgical procedures.

A thorough preventive maintenance program is essential for safe

and proper operation of your surgical light. You are encouraged to

contact STERIS concerning annual maintenance agreements. Under

the terms of this agreement, preventive maintenance, adjustments

and replacement of worn parts are done on a scheduled basis to

verify lighting fixture performance according to its specifications and

to help avoid untimely or costly downtime. STERIS maintains a

nationwide staff of well-equipped, factory-trained technicians to

provide this service, as well as expert repair services. Contact

STERIS for details.

Indications for Use The HarmonyAIR® Surgical Lighting System E Series is a variable

pattern, variable intensity surgical lighting fixture designed to

provide visible illumination of the surgical field for the operating room

staff.

Advisory The following is an important message from STERIS about the

advantages and limitations associated with the use of high

intensity surgical lighting systems.

Because of the variety of surgical procedures performed and the

wide range of individual preferences of surgical staffs, it is desirable

that a surgical lighting system be capable of selective control across

a wide range of illumination intensities. The Illuminating Engineering

Society (IES) stresses that in addition to providing control of

intensity, surgical lighting systems should provide shadow control,

correct color rendition, and a suitable depth of field to provide sharp,

consistent lighting into deep body cavities. As illumination levels

increase, however, radiant heat also increases. Therefore, the IES

cautions that for most operations, radiant heat should be kept to a

minimum. The user of surgical lights should utilize the lowest

possible illumination level suitable for the procedure, especially in

certain neurological or intestinal procedures on delicate, thin, dry or

abnormal tissue. Furthermore, for the protection of surgically

exposed tissues and for the comfort and efficiency of the surgeon

and assistants, radiant energy can be effectively controlled by

limiting the time of exposure at higher illumination levels. Extra care

must be taken when the light fields from multiple lightheads are

overlapped on the surgical site, since this condition creates a risk of

too much heat and excessive UV irradiance.

ii

10099907 Operating Instructions Introduction

An international standard for the safety of surgical lights established

by the International Electrotechnical Commission (IEC) sets minimum

and maximum levels of illumination and maximum levels of radiant

heat that can be emitted from a single surgical luminaire. The

HarmonyAIR E Series has been designed to comply with this

international standard and to provide a wide range of illumination

levels while minimizing the potentially damaging infrared heat in the

surgical field.

The illumination level of the HarmonyAIR E Series Lights can be

adjusted through several intensity settings via conveniently located

controls on either the wall-mounted control center or the lighthead

handle. The illumination level also decreases as the pattern size

increases. Maximum illuminance can reach 160 klx for the smallest

pattern size of HarmonyAIR lighthead, and can be adjusted by

intensity control or pattern size control throughout the entire range

specified by the IEC.
