Introduction

The Holten LaminAir Sterile series are thoroughly tested products designed to protect the work process and the handled product against particle or microbiological contamination.

The HV series comply with I.E.S. Recommended Practice: IES-RP-002-86. January 1986. Laminar Flow Clean Air Devices and the Nordiska R3-foreningenns Norm for oppna LAF-enheter.
In order to avoid unintended wrong attendance, please read this instruction manual carefully

Description

A confined workspace in which stable vertical unidirectional flow (laminar flow) provides protection for the product handled against particulate contamination from the surroundings and the operator.

All operations take place through the front opening. Pressure in the work chamber keeps the clean air flowing from the work chamber to the surroundings, avoiding the introduction of particulate contamination to the work chamber

Technical description

Airflow in the work chamber Through the perforated opening in the top of the bench air from the surrounding room is drawn into the bench. The air is pre- filtered through a filter with medium efficiency.

Prefilter

The prefilter efficiency is 83 % Ashrae 52/76 (gray.) corresponding to EUROVENT 4/5 classification EU 3. The air is then led to the fan.

Fan

The air is led to the fan at the top of the bench where the air i3 pressurized. The fen is of self-compensating type and has only an insignificant drop in supplied air volume by an increase in backpressure. By means of a built-in transformer, the fan can be made to operate with increased power. From the pressure plenum, the air passes the main filter.

Main filter

The filtering efficiency of the main filter is 99.999 % of particles 0.3 pm (D.O.P.test). Air flows from the main filter through the work chamber in a vertical unidirectional flow of clean air. Immediately before reaching the tabletop the air separates and partly flows out through the perforated hack wall, partly flows out through the work opening. The air returns to the suction opening of the bench passing through the surrounding space.

  • The fan is built into the upper part of the bench and is accessible from the top through the cover at the back of the bench or from the back.
  • The electronic control panel is built into the lamp cover. Main connections, fuses, and transformers are placed underneath the cover at the top of the bench.
  • The window is fixed.
  • The hinged window, which is made of polycarbonate, can be opened and kept open by means of damped gas pressure springs.
  • The sash window is made of polycarbonate. It is adjustable in height and keeps itself in place.
  • The lighting of the work chamber is placed outside the work chamber behind the lamp cover.
  • The lighting is glare-free and causes neither turbulence nor undesired heating of the work chamber.
  • All switches, pushbuttons, and signal lights for operation are together with the hour counter gathered in a control panel on the front of the lamp cover.

Installation

Placement: Check that the dimensions of the bench (see figure 2, page 5) make free access to the wanted site possible. The lamp cover can be demounted for obtaining a minimum width of 650 mm.

| NOTE
The demounting should be carried out by a qualified service technician (Contact your local dealer for further information).
---|---

The place of installation should be a place without draught and a place where passing-by of persons is avoided.

On existing tabletop:
Before placing the bench, make sure that the existing tabletop is able to carry the load of the bench. (See section 4 technical data).

Floor stand:

• Place the table stand on the wanted place of installation.
• Lift the bench onto the floor stand in such a way that the aluminum plugs slide into the floor stand.
• Use the fastening screws to fasten the stand to the bench.
• Adjust the leveling screws on the stand so that the tabletop is horizontal.

| WARNING
Prior to electric connection, it must be checked that the mains supply corresponds to what is stated on the type plate. For increased safety, the connection can be carried out as a fixed installation.

D. Pushbutton with signal light (blue) for switching the light in the work chamber on/off.
E. Push button for start/stop of fan and signal light (green) for normal fan speed.
F. Hour counter.

Re Red alarms light for insufficient flow. The velocity in the laminar flow is below the wanted minimum value. The green lamp E turns off when the alarm is on.

Re B Yellow lamp for UV-light can only be activated when the main light is off.
Re C With the yellow switch it is possible to choose between normal and reduced fan speed. By operation at reduced speed, the effectiveness of the product protection is also reduced.

When a product is handled in the unit it is therefore essential that the unit is operated at normal fan speed. Operation at reduced speed is only to take place when the unit is not in use. The use of reduced speed reduces the risk of contamination of the work chamber between the handling of products. Re D the work chamber lighting can be switched on and off.

Working rules

8.1. Working rules before work is started

• About 15 minutes before work has started the fan of the bench is switched on for operation at normal speed. A green control light indicates proper operation.
• The work chamber is to be carefully cleaned and/or disinfected. Use 70 % ethanol or the like. It is recommended to use special lint-free wipes. Use preferably aqueous detergents on the front window and on the side windows – never use detergents containing chloride. Use mainly a soft cloth in order not to scratch the windows.
• Objects and remedies must be carefully cleaned and/or disinfected before being brought it du LI le walk utuarribei.
• Necessary remedies for use during work must be placed within reach.
• Put on necessary personal clothing for reducing particle emission from the operator (e.g. gloves, masks, and general cleanroom clothing). Special attention should be focused on hands and lower parts of arms, as these are the parts of the person most likely to emit particles near the product.

8.2. Important in order to work under clean conditions

• Never perform any work with the fan at reduced speed.
• Work with tranquil movements.
• Never overload the work chamber.
• Reduce the number of transports into the work chamber.
• Avoid remedies with strong emission of heat.
• Do not place the bench on places with direct draught towards the work opening.
• Avoid placing the bench where many persons pass by.
• For reliable operation, it is important that the airflow conditions are as undisturbed as possible. Therefore, never overload the work chamber – only remedies necessary for the actual work should be placed in the work chamber.

8.3. Working rules during work

• All work on the bench must be performed with tranquil movements. Quick arm movements in Ole wuni, the chamber may cause slips Ueams Mat will thdWlifItileti ail into the work chamber.
• The number of transports into the work chamber must be minimized. Transport of possibly contaminated material may in addition to the mechanical transport also cause the formation of airflow’s which create a connection between the product and the contaminated surroundings.
• Heat-emitting products or remedies in the work chamber may disturb the wanted air movements. Around sources with strong emission of heat. The air is hand thus creating an up-current that will cause unstable conditions in the unidirectional flow. The protective effect of the bench may then disappear.
• Use preferably bunsen burners with possible hand or foot-operated reduction of the effect.
• Draught towards the work opening can destroy the protective effect of the unidirectional flow.
• Passing-by of persons in front of the bench should be minimized. An onward movement in front of the work opening will create a pressure wave in front of the person Passino-hy of a person might therefore cause air from the surrounding space to be pressed into the work chamber The effect is intensified the faster the person is moving and the closer to the opening the passing takes place.

Maintenance

9.1. Recommended maintenance

Daily
The work area is cleaned. Be especially careful when cleaning the work surface.

Weekly
Wipe the exterior of the bench with a mild detergent of household type. Antistatic spray can be used for cleaning the front window.

Regularly
The reliable operation of the bench is based on the following conditions:

1. Correct air velocities.
2. The efficiency of the installed HEPA filter.

| NOTE
These parameters should be tested by a qualified technician after approx. 5000 hours of operation or at least once a year.
