7. SERVICE AND MAINTENANCE
ALWAYS bring the light outside the MRI room when performing any service on the
light. This includes any cleaning and/or bulb replacements. The ceiling light balance
arm can be detached and brought out of the MRI room for maintenance or repair.
Assemble the mobile light outside of the MRI room.
The safety guidelines of your MRI facility must NEVER be compromised. If in doubt,
consult with your facilities manager on proper procedures.
While your CELESTIAL STAR light has been designed to provide you many hours of professional
performance, it will benefit from your periodic care and concern. The lamp head is constructed of high
impact polycarbonate which exhibits certain strength and thermal characteristics, offering a protection not
available with metal reflector lamps. One reward is a lack of heat build-up normally experienced with metal
reflectors, thus eliminating the danger of burns from contact made with those hot reflector surfaces, either by
you or your patient.
Detachable parts
Lamp head: Bulb housing, bulb
Light assembly: Joint of vertical pole and balance arm, joint of vertical pole and caster base, caster wheels,
counter weight
Electrical box: Light cord connector and electrical box receptacle
CAUTION! In the event, parts need to be replaced, only Sunnex parts should be used as
replacements, use of other parts or materials can degrade safety. Also, there are no user-serviceable
parts in the Celestial Star series MRI light.
7.1 CLEANING AND DISINFECTION
CAUTION! ALWAYS SHUT OFF THE LIGHT AND LET COOL BEFORE PERFORMING ANY CLEANING.
Good physical characteristics of polycarbonates offer additional advantages. While metal reflectors are
susceptible to denting, which will distort their beam pattern, the frame and covers of the CELESTIAL STAR
provide a safeguard to the lamp/reflector assemblies. In combination with the low voltage circuitry, they offer
a level of “double insulation” against possible current leakage. The covers and frame may easily be cleaned
with a soft damp cloth of a mild soap water solution or mineral spirits. Isopropyl alcohol is another
acceptable cleansing agent. The heat absorbing front glass filters offer a protection between the
lamp/reflector and the patient. They provide a barrier to falling pieces of those assemblies should they
experience a physical failure. In addition, they contribute to a cooler task site by absorbing certain light rays
which could dissipate into heat when incident on the task surface. They can be cleaned with any commercial
glass cleaner. The metal components are powder coated for long life, while providing another layer of
insulation. They too can be cleaned with a damp cloth of mild soap and water solution, mineral spirits or,
isopropyl alcohol.
CAUTION! DO NOT USE EXCESSIVE AMOUNTS OF ANY FLUID WHEN CLEANING.
DO NOT INTRODUCE ANY FLUIDS TO THE INSIDE OF THE LAMP HEAD
HOUSING.
SUGGESTION: Periodically dust the backside louvers to ensure uninterrupted convection of ambient air and
filtered infra red rays through them. This air movement also cools the three lamp/reflector assemblies,
further extending their effectiveness and useful life. A suggested frequency of cleaning and maintenance is
one month.
