LASERVAC 750™
1. GENERAL
The Laservac 750™ Smoke Evacuation System has been designed to remove all smoke plume, particulates and obnoxious odours produced during laser surgery. The Laservac 750™ is a totally self contained, portable machine, very quiet in operation with variable flow capabilities, ideally suited for all types of laser surgery. It is very simple to use with a full range of disposable filters and accessories including a pneumatic foot switch.
The Laservac 750™ Filtration System consists of two High Efficiency Filters connected in series, (one inside the other). The Primary Filter removes bulk contamination whilst the Secondary Filter de-odourises the air and removes down to virus size particles. Due to the direct link between the filters and their location prior to the vacuum motor there is no possibility of contamination reaching other components or the inside of the cabinet. The overall efficiency of the filtration system is >99.9999% at 0.12 microns.
2. STANDARDS
The Laservac 750™ is manufactured to the highest engineering standards incorporating a very strong cabinet moulded from foamed polyurethane. The electrical system conforms to CANCSA C22.2 No 601.1-M90 Category 245 & UL-544 /ETL Product Category 6 for Medical and Dental Equipment.

3. DESCRIPTION
The Laservac 750™ is a portable lightweight system with a ‘built in’ carrying handle and when in operation it sits on two moulded feet. The purpose moulded cabinet has smooth lines with a high quality surface finish to eliminate dust traps and aid in the cleaning of the unit. The cabinet incorporates several special features including: front control panel, rear stowage compartment with latchable lid, louvres for internal cooling and excellent acoustic properties. The Laservac 750™ consists of the following major components. 3.1
Vacuum Pump
The vacuum source is a dry running, two stage ‘by-pass’ vacuum motor. This high capacity motor runs on a single phase 110/120V60Hz or 220/240V-50Hz electrical supply and requires no lubrication. As a protection measure the motor has a thermal cut-out to prevent over-heating.
3.2
Primary Filter
The Primary Filter consists of a two part plastic housing containing a high efficiency filter element for removing bulk contamination. This filter fits directly into the Secondary Filter by means of a simple bayonet connection. The outer portion of the filter housing is made from clear plastic to allow visual monitoring of the element during operation. Lifetime of the Primary Filter depends on usage and the type of surgical procedure performed. Walker Filtration recommends that the Primary Filter is replaced after every operation.
3.3
Secondary Filter
The Secondary Filter consists of a duplex filter element sealed inside an enclosed cannister. This filter which is fitted inside the machine is designed to remove obnoxious odours, fumes, vapours and bacterial sized particles. Lifetime of the Secondary Filter depends on usage and type of surgical procedure performed. Walker Filtration recommends that the Secondary Filter is replaced at least every six months. In cases where unpleasant odours are positively detected from the smoke evacuator earlier than six months, then earlier replacement is required.

3.4
Electrical Control System
The Laservac 750™ can be switched ON and OFF by means of an illuminated rocker switch located on the front control panel. The control panel also has a variable speed control knob. The vacuum level/air flow rate can be set for optimum performance by rotating the speed control.
3.5
Pneumatic Foot Control
The Laservac 750™ has a Pneumatic Foot Switch located in the rear compartment. This can be removed from the compartment and used to operate the machine remotely but only when the rocker switch is in the ON position.
4. ACCESSORIES Each Laservac 750™ is supplied with a Starter Pack containing all the items required to install and operate the unit. The Starter Pack consists of the following items:Walker Filtration Part. No.

5. ELECTRICAL SYSTEM
The electrical schematic diagram is included at the back of this manual, page 11. 5.1
Fuses
The machine is protected by two anti surge line fuses located within the IEC mains inlet socket.
5.2
Thermal Cut out
The machine is further protected by a thermal cut-out switch. If, due to any circumstance this switch trips out, it will reset itself when the machine cools down to the normal operating temperature. WARNING If the thermal cut-out operates, the machine must be disconnected from the mains power supply and allowed to cool down before being switched ON again. The cooling down period will take at least 30 minutes. The obvious cause of the thermal cut-out operating is if the cooling fan inlet filter is blocked or obstructed.
6. OPERATIONAL DATA
6.1
Performance
Under clean conditions the Laservac 750™ will draw 300L/m (10 scfm) with the Speed Control on minimum and 750 L/m (26 scfm) when on maximum through a 22mm (7/8”) dia connection hose. If the performance drops to an unacceptable level the Primary Filter will need replacing.

LASERVAC 750™
6.2
Noise Levels
The use of extensive sound insulation and noise suppression within the cabinet has given the Laservac 750™ a noise level of less than 60 dbA when measured at 1 metre. The Laservac 750™ should be operated at the lowest acceptable speed setting to give the lowest noise level.
7. COMMISSIONING
The LV750™ Smoke Evacuator has been fully tested prior to despatch however, due to possible damage in transit, the following checks and precautions should be taken :1) Check for transport damage and shortages. Advise your Walker Filtration dealer immediately if there are any discrepancies. 2) Check the back panel serial plate to ensure the voltage and frequency are correct. 7.1
Initial Start-Up
The following procedure should be used :1) A two metre long mains lead is supplied in the Starter Pack, an IEC plug is moulded onto one end and a suitable 3-pin mains plug must be connected to the other end. Observe the label attached to the lead for wire identification. The machine must NOT be operated without an earth connection. 2) Ensure the rocker switch is in the OFF position. 3) Rotate the Speed Control anti-clockwise for minimum setting. 4) Fit a Primary Filter into the front aperture and rotate clockwise to lock in position. NOTE - the clear plastic portion to the out side. 5) A standard IEC 320/CEE22 mains inlet socket is located at the rear of the machine. Fit the IEC plug into the socket and connect to the mains supply. Switch the mains ON.
