2. DESCRIPTION
2.1 General Designed for optimum versatility, the LASERVAC 850 has a variable flow and speed control, ensuring that it can be used in all types of laser or electro surgery, with all medical lasers. Mobile and compact, the LASERVAC 850, is self contained and portable filtration system with built in anti-static castors and handle for full manoeuvrability. The units stand vertically and have a small footprint making them ideal for any surgical setting. The LASERVAC 850 is simple to operate and utilises a soft touch display and user friendly informative control panel. The LASERVAC 850 incorporates several special features:2.2 Membrane control panel The LASERVAC 850 laser smoke evacuator incorporates a user friendly, soft touch membrane control panel. Conveniently situated, at hand level, the membrane control panel allows the operator maximum control and flexibility to suit the exact surgical procedure. The control panel features an ON/OFF button and facilitates variable speed and flow control. 2.2.1 Variable speed control At the touch of a button, the flow can be increased or decreased according to operator requirements. The flow rate is fully adjustable to maintain optimum flow rate and noise level. (See page 2) 2.2.2 Filter monitoring The membrane control panel shows clearly the operating life of the primary and secondary filter. A flashing LED, which gradually increases in scale, illustrates when a filter change is necessary. This assures optimum performance and cost effective filter replacement. (See page 2) 2.2.3 Service indicator A service indicator light provides a clear warning that the LASERVAC 850 is due for a routine annual service (See page 2). Walker Filtration offer a complete service policy. Contact the Medical Sales department, for full details. 2.3 Vacuum pump The vacuum source is a dry running, two stage “by pass” vacuum motor. This high capacity motor can run on a single phase and is available in either 230V-50Hz or 115V-60Hz electrical supply and requires no lubrication. As a protection measure the motor has a thermal cut out to prevent over heating. 2.4 High efficiency filtration All filters are safe, quick and easy to replace and no special equipment, tools or training is required. Each filter utilises high efficiency pleated media, which is housed within a surrounding casing, to ensure thorough capture of debris, particulate matter and noxious odours. The LASERVAC 850 laser smoke evacuator has a unique inter-connecting filter arrangement for complete environmental protection . All filters are disposable and can be incinerated.

Primary Filter LVPF850
Secondary Filter LVSF850
2.4.1 Primary filter LVPF850 The disposable primary filter, consists of a plastic casing containing a pleated, high efficiency, filter element for removal of bulk contamination. The primary filter has an efficiency of 99.999995% at 0.01 micron, to remove debris and particulate matter created during laser surgery. The primary filter seals onto the liquid collection trap and fits directly onto the secondary filter , by a simple quarter turn knob. It is necessary to change the primary filter on a frequent basis for optimum performance. It is recommended that the primary filter is changed after two hours. The control panel has a built in service life indicator, which will flash when the primary filter is to be changed. When the primary filter is replaced the indicator will automatically re-set (see point 9). For specific information, please refer to the instruction leaflet 04 196 001 01 supplied with each new primary filter. 2.4.2 Secondary filter LVSF850 The secondary filter combines a two stage, high efficiency filter to remove viral size particles down to 0.01 micron at 99.9999995% and to adsorb obnoxious odours. The disposable filter, consists of an aluminium casing bonded to a moulded nylon end cap and contains pleated, bacterial ULPA grade and activated carbon filter media for dual purpose performance. The secondary filter is located underneath the primary filter and can be quickly released from it’s position by pressing a spring loaded clip down wards. It is necessary to change the secondary filter at least every six months. The activated carbon has a scavenging effect, which continually adsorbs odours even when the LASERVAC 850 is not in use. It is recommended that stock of the secondary filter is rotated and the “use by date” on the box is observed. (See point 9) The control panel has a built in indicator which will flash when the secondary filter should be changed. When the secondary filter is replaced the indicator will automatically reset. For specification information, please refer to the instruction leaflet 04 185 001 01 supplied with each new secondary filter. 2.5 Liquid trap LVLT850 The liquid trap is a cautionary measure to protect the LASERVAC 850 from the accidental ingress of any potential liquids. The liquid trap inserts directly into the front of the cabinet and is held in place by the primary filter. The transfer tube fits directly into the liquid trap. If the liquid approaches the MAX. level indicated on the collection trap (0.75 Ltrs/1.6 US pints) the LASERVAC 850 should be switched off at the mains immediately and the liquid collection trap replaced. In most cases, the liquid trap should be removed when it begins to show signs of discolouration. If liquids have been present, the primary filter (LVPF850) should be replaced as a matter of course. (See point 9). For specific information, please refer to the instruction leaflet 04 206 001 01, supplied with each new liquid trap.

Caution : 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. 5.1 Performance Under clean conditions the LASERVAC 850 will draw 850 Lm-1 (30 cfm) through a 22 mm transfer tube. When the performance level of the machine falls to an unacceptable level, the primary filter should be replaced. (Also see problem solving). For optimum performance:- ● Ensure that transfer tubes are no longer than required ● Ensure that there are no kinks in the transfer tube ● Ensure that the collection device is as close to the smoke plume source as possible
6. COMMISSIONING
5.2 Noise Levels The use of a quiet vacuum pump and acoustic cabinet provides a noise level in order of 59 dBA, measured at 1 metre. This ensures that the LASERVAC 850 can be used in close proximity to the operator and patient without any inconvenience. The Laservac 850 should be operated at the lowest acceptable speed setting to give the lowest noise level. 6.1 Check procedures The LASERVAC 850 machine has been fully tested prior to despatch, but due to possible damage in transit, the following precautions should be taken :6.1.1 Check for transport damage and shortages. Check the contents is as stated on the box label. Advise Walker Filtration, or authorised dealer, if there are any discrepancies. 00 PAGE 09
6.1.2 Check the incoming supply voltage and frequency correspond to the specifications shown on the serial plate, fixed to the reverse of the machine. 6.2 Initial Start Up CAUTION - Ensure the unit is not operated without filters installed The following procedure should be adopted :6.2.1 A 2.0 metre long mains lead is supplied in the starter pack. An IEC plug is moulded onto one end and a suitable medical grade mains plug must be connected to the other end by a competent person. Observe the label attached to the lead for wire identification. The machine must not operate without an earth connection. 6.2.2 The LASERVAC 850 should arrive assembled with a liquid trap, primary and secondary filter. (See section 2 for replacement instructions.) 6.2.3 Connect the transfer tube by pushing it firmly into the liquid trap. 6.2.4 Switch the unit on at the IEC mains socket at the rear of the unit. This will illuminate the display and the speed control will default to zero. Press the ON/OFF button, on the control panel. The adjacent LED will illuminate to indicate the unit is now on. 6.2.5 The arrow buttons above and below the numeric display panel, indicate increase and decrease of flow rate. To start the motor press the “arrow up” button. With each depression of the arrow-up button the flow rate and digital display will increase up to a maximum level of 9. To slow the motor down, press the arrow-down button below the display and, the flow will reduce in a similar manner. 6.2.6 Depressing the on-line button on the LASERVAC 850 control panel will stop the unit from running. 6.2.7 If the smoke evacuator is required to be operated remotely, the pneumatic foot switch should be connected into the rear of the unit. Once the desired flow rate has been set, the foot switch can be used to turn the unit on and off as required. When the foot switch is not required it can be stored in the rear stowage compartment.
7. SAFETY PRECAUTIONS
6.2.7 The display will remain at the speed it is set at until it is switched off at the mains switch. ENSURE THESE INSTRUCTIONS ARE FOLLOWED. 7.1 Do not use the LASERVAC 850 within the “Zone of Risk” this being an area extended from 25 cm around any part of the anaesthetic circuitry and the gas paths of any anaesthetic apparatus. Within this area, full precautions must be taken with respect to flames, hot surfaces or sparks from all causes. 7.2 Always switch the machine OFF when not in use and remove mains lead. The unit must always be switched OFF for maintenance and consumable part replacement.
