SECTION 1 - INTRODUCTION
The SGI SpectraPure Model No. 5300 Room Air Purifier functions as a component of the SpectraPure 5300 Air Purification System. The purifier is intended to remove the toxicity of halogen gases and halogen gas compounds that may be present in laser room air in the event of an accidental release of the excimer laser gas mix. The SpectraPure 5300 Air Purifier was designed to reduce toxic gas contamination to safe levels in the average sized laser surgery room. Should the laser room
air accidentally become contaminated with excimer laser gas mix, all personnel should immediately evacuate the room. The Air Purifier can
be remotely or automatically actuated, depending on the purchase option. The purifier uses a high flow blower to circulate room air through an activated charcoal filter. The purifier draws contaminated air into the lower intake grill and then through the filter compartment. The halogen and halogen compounds are removed by the filter and purified air is exhausted through the top grill on the unit. For proper operation, the
purifier requires unrestricted air flow at the inlet and the outlet.
The purifier is designed for easy operation and can be manually turned On or Off. As an optional configuration, the Air Purifier can be mated to the SGI Model No. 215 Gas Cylinder Storage Cabinet for the purpose of ventilating the cabinet. The SpectraPure 5300 System can also be equipped with the SGI Series 6400 Gas Detector. The detector may be used to automatically turn on the Air Purifier at factory set ppm levels. The detector may also be used to monitor room air quality conditions.

1.2 - IMPORTANT SAFEGUARDS
When using the SpectraPure Model 5300 Room Air Purifier, always
follow these basic safety precautions:
1.Read these instructions completely before installing or using the purifier.
2.Attach the power cords to appropriately rated and grounded plugs. Keep the cords away from hot surfaces. Never ground them to a gas pipe or water pipe.
3.Take precautions to insure that safe and adequate wiring is installed in observance of all pertinent local electrical codes. WARNING: The SpectraPure 5300 must be supplied with uninterrupted wall voltage and left in Standby Mode (see Section 4.2.1) in order to insure activation in the event of an accidental release of excimer laser gas into the laser surgery room air.
4.Do not disassemble the equipment, or try to repair it yourself without first checking with a manufacturer's representative.
CAUTION: Risk of electric shock. Service access panels should be removed only by qualified servicing personnel.
5.Since line voltage is present in the purifier during operation, it is recommended that proper caution is observed and that all panels be mounted on the purifier while operating.
6.Turn OFF the MAIN Circuit Breaker ON/OFF Switch and unplug the purifier power cord when servicing the purifier, (the purifier is shipped from the factory with the MAIN switch turned OFF).
1-2
WARNING: The MAIN Circuit Breaker must be in the "I" (on) position in order to enable a STANDBY ready condition to exist and to allow the air purifier to respond properly in the event of an accidental release of toxic gas into room air.
7.Complete proper installation in accordance with Section 3 of this manual with proper clearances in the rear, in the front, and on top of the equipment.
8.Do not install the Air Purifier in a room larger than 3000 cubic feet without making additional provisions for purifying room air. Maximum recommended room air volume processing capacity of the SpectraPure 5300 Air Purifier is 1750 cubic feet. Room dimensions should be rectilinear or square shaped, see Section 2.4.2.
9.Do not obstruct air flow to Air Purifier intake or exhaust vents.
10.Take precaution to prevent facility supplied HVAC air flow from competing with SpectraPure Purifier air flow during operation. In addition to impeding air purification, HVAC air intake vents may draft toxic fumes into other areas of the medical facility.
11.Install the SpectraPure 5300 in direct proximity of gas storage cylinders and the laser surgery device. Use only properly rated SGI medical laser gas cylinders. Use of any other gas cylinders may nullify warranty coverage and could create a severe safety hazard. Do not re-locate equipment without contacting SGI for technical assistance.
1-3
12.Do not operate the purifier if any part of it is damaged, or if any part has been dropped, until you have it checked by a qualified service technician.
NOTICE OF CAUTION AND WARNING
The Seller herein informs the Buyer that there are hazards associated with the use of compressed halogen gases, and that proper provison must be taken to insure the safe handling of these gases. The SpectraPure 5300 Air Purifier is intended to function only as a component of a halogen gas handling system. This system must include whatever equipment, facilities and procedures as may be necessary to comply with all pertinent ordinances and safety codes.
By installing and using the SpectraPure 5300 Air Purifier, the Buyer accepts full responsibility for the proper installation and use of this product.

SECTION 2 - THEORY OF OPERATION
2.1 - SUMMARY
The SpectraPure Model 5300 Room Air Purifier is an air cleaning device that is specifically designed for use with excimer laser-based
medical equipment. Excimer lasers produce very short wavelength
ultraviolet light by stimulating the emission of radiation from a lasing medium containing a specific mixture of rare gases (such as
Argon, or Xenon) and halogen gases (such as Fluorine, or Chlorine).
The halogen gases, though used in very small quantities, are very chemically reactive, and are therefore toxic. Commercial medical laser products are designed to provide safe and reliable means of controlling the containment of the halogen gases that are used to generate excimer laser light output. Typically, the gases are stored in compressed gas cylinders, which are enclosed inside ventilated gas storage cabinets. The possibility of a release of toxic gas into the medical laser environment exists when the gas storage cylinders are handled or replaced. Therefore, despite the very low probability of occurrence, a
properly |
installed |
medical excimer laser |
system should |
include |
emergency |
provisions |
for safely detecting, |
controlling, and |
removing |
any halogen gases that might be accidentally released into the medical environment. The SpectraPure 5300 provides an economical and convenient means of reducing the health hazards that may be associated with an accidental release of toxic gas into the medical laser environment. Alternative toxic gas removal methods may include more expensive facility gas control and fume scrubbing systems which must be
2-1
specifically engineered for the removal of halogen gases at the particular facility in compliance with local air quality codes.
2.2 TOXICITY HAZARD INFORMATION
To reduce toxicity, medical excimer laser gas mixes contain small quantities (less than 1%) of halogen. Also, as an added fail-safe measure, gas storage cylinders are typically equipped with permanent flow restricting orifices to retard the rate of emission of laser gases into the room air in the event of an inadvertent release of gas. For this reason, accidental emissions from the gas cylinder to air, if left uninterrupted, are gradual. Figure 2.1 illustrates a typical rate of emission from a properly flow restricted gas cylinder.
FIGURE 2.1 TYPICAL RATE OF EMISSION OF GAS FROM A FLOW RESTRICTED
GAS CYLINDER
2-2
When exposed to air, halogens react with the air to form compounds such as acid gases (e.g. HF). Health hazards resulting from exposure to halogens and halogen compounds are quantified by OSHA and other health reporting agencies in limits for short term and long term exposures. Long term exposure limits are lower than short term limits. Fortunately, human smell is highly sensitive to the presence of halogens and halogen compounds in the very low ppm range. (e.g. 1-2 ppm fluorine). Long term halogen exposure limits are generally higher than the sensitivity of human smell.
The SpectraPure 5300 is intended to reduce the hazards associated with a short term exposure resulting from an accidental release of laser gas mix into room air. The SpectraPure 5300 cannot immediately eliminate odors that may be caused by the presence of halogen gas in the room air.
The low probability of release of excimer laser gas into room air might exist during a gas cylinder servicing routine. Cylinder servicing should be conducted only by trained and certified personnel during off-hour schedules, i.e. when the medical laser facility is not being used to treat patients. Off-hour scheduling, in addition to other equipment features and handling procedures, can significantly reduce the possible risks that may be associated with an unintended gas emission.
2.3 - AIR PURIFICATION METHOD
The SpectraPure 5300 Air Purifier functions to remove halogens, and halogen compounds from room air by circulating the air through a
2-3
highly absorbent activated charcoal (carbon) filter bed. The air is circulated by a doubleheaded 1000 CFM centrifugal blower. The blower circulates air through the room and mixes purified air with air that may be containing residual halogen gas. The carbon filter element reacts readily with any halogens that may be present in the room air to immediately form non-toxic halo-carbons. Each pass through the filter bed removes most of the halogen in the air that is passed through the filter.
The purifier air intake is located at the lower grill on the front of the unit. The room air is forced through the filter bed and exhausted through the top of the unit. No external duct work is required to install the SpectraPure 5300 Air Purifier. The purifier is designed to purify room air while circulating air through the room in which it is physically located. In order to produce high flow rates and clean the room air as quickly as possible, the purifier is designed for minimal flow restriction and features wide flow cross sections.
IMPORTANT WARNING: The SpectraPure 5300 Air Purifier is designed for easy and reliable operation. However, the unit must be properly installed, and air flow through the intake and exhaust vents cannot be obstructed or performance may be significantly impeded.
2.4 - PRINCIPLES OF AIR MIXING
As the SpectraPure 5300 Air Purifier cleans contaminated room air, it mixes purified air with contaminated air. If the gas leak emission has terminated, this purification process results in an exponential
2-4
dilution of the toxicity level in the air as purified air is mixed with contaminated air. Figure 2.4.0 illustrates the exponential rate of purification of contaminated air.
FIGURE 2.4.0 - EXPONENTIAL DILUTION OF CONTAMINATED AIR AS A FUNCTION
OF MIXING
Several environmental factors may affect the efficiency of air circulation through the SpectraPure 5300 Air Purifier, such as the location of the purifier, the shape of the room, placement of objects in the room, etc. Because these factors may vary according to individual user locations, they are installation specific issues and must be properly addressed during the installation of the SpectraPure 5300 system. Recommendations for optimal installation are provided in Section 3 of this manual.
2-5
2.4.1 - Rate of Contamination vs. Rate of Purification
In the event of an accidental gas leak, the design of the SpectraPure 5300 assumes that toxic gas will continue to be released into the room as the purifier begins to clean the room air. The flow rate through the SpectraPure 5300 Air Purifier is much larger than the flow restricted cylinder leakage rate, so that the average atmospheric halogen and halogen compound concentration levels in the room are maintained at minimally toxic levels. As the cylinder gas level is depleted, the emission flow rate is reduced and the concentrations level of halogens in the room air will then be further reduced. Initially, the halogen and halogen compound concentration in the room will rise to a maximum as cylinder pressure is at a maximum. As the cylinder pressure drops, the halogen and halogen compound concentration in the room will be brought down gradually by the room purifier until the air contamination is brought to the sub ppm range. Figure 2.4.1
illustrates |
the |
combined effects of the competing rates of |
contamination |
and |
purification on halogen concentration in the room |
air. |
