INTRODUCTION

The SWIFTLOCK range are modern, functional general - purpose laboratory

STERILIZERS designed with ease of use in mind . They feature the proven

SWIFTLOCK CLOSURE PAT system to give easy and rapid opening of the chamber,

together with an easy-to use Single- or Multi-program control system, to facilitate a

variety of uses.

GENERAL OPERATION AND LOG-BOOK

Although the historical safety record of laboratory STERILIZERS is good, remember

at all times that they store considerable potential energy, and should be treated with

respect and care. If correctly used and cared for, your ASTELL STERILIZER will

provide long, reliable & safe service.

Pay proper attention to regular maintenance. Never force the locking mechanism, or

operate the machine with any leaks, or incorrectly operating parts.

Report any defects to your Engineering/Supervisor. If deterioration or defects are

noticed, record them in a log book and contact our Service Department .

Record also the results of annual and periodic inspections. Every 4 to 6 weeks is

recommended for periodic checks. Check the logbook before you start using the

machine, as someone else may have recorded a fault of which you are not aware.

MACHINE SPECIFICATION AND CONTROL OPTIONS

The Control System Display will show various items of information when the Mains

Power is turned on , for example...

"SWIFTCLAVE STERILIZER" denotes STERILIZER Type

"ELECTRICAL HEATING" or "STEAM HEATING" "SOFTWARE ISSUE No. xyz"

WATER & STEAM SERVICES &

DRAINAGE PIPEWORK CONNECTIONS.

• The TANK DRAIN outlet must be connected to a suitable Building Drain to carry away

waste water.

• The Safety Valve exhausts into the room.

• A supply of cold Mains water is required

• The Autofill tank Overflow / Warning Pipe must be correctly arranged.

• Electrically heated models are provided with a Chamber Cleaning Drain which may be

connected to the Building Drain .

• Steam heated models require a supply of steam .The Condensate Drain should be

connected to the building drain .

PIPEWORK CONNECTIONS. and installation details

TANK DRAIN OUTLET

This is a 35 mm plastic drainage outlet pipe projecting from the rear of the machine.

It must be plumbed into a building drain , and carries water with a temperature of up to 60C, but

normally ambient-40C. The outlet pipework should be free-draining and have a downward slope of a

min. of 1- in 50 and should not be reduced in diameter. If the length is to exceed 10 metres the whole

of the length of drain pipework should be increased in diameter by at least one size.

MAINS WATER INLET

This is a Plastic Coloured Hose with a 3/4 BSP Female Threaded tap connector similar to a Washing

Machine Inlet Hose. This should be connected to a Cold Water Mains Supply , Minimum 0.5 Bar ,

Maximum 6 Bar pressure. This supply Must be provided with a Shutoff Valve ( a Washing-Machine-

Isolator Valve is suitable ). The supply must provide for a Maximum Flow-rate of 10 litres/minute.

DRIP-TRAY DRAIN

There is no separate driptray drain this is incorporated with the Tank Outlet.

TANK OVERFLOW / WARNING PIPE

This is a White Polypropylene 20mm pipe which projects from the rear of the machine and will carry

overflow water if the Level in the Autofill tank is too high. It should be fed to an open Tundish or drain.;-

U.K. Water Research Council and the U.K. water byelaws require Warning pipe outlets to be visible to

the operator.

SAFETY VALVE

The Safety-Valve exhausts vertically downwards at the rear of the machine close to the floor. When it

operates a large volume of low-velocity steam will be produced .

It must not be connected to any other pipework or altered .

Please see other references in this manual to SAFETY-VALVE TESTING.

AIR INLET

This is a screwed inlet socket fitted inline with a 1-way valve. An optional bacteriological filter is

available which may be-fitted to allow clean air- into the chamber as it cools. Consult your Supplier for

details of suitable filters.

DRAIN VALVE - Electric Heated Models ONLY

The Drain valve permits the Chamber to be drained for cleaning purposes. This is at the rear of the

STERILIZER fitted with a lever action hand-valve. The valve is shut when the handle is at RIGHT-

ANGLES to the pipe. This should be arranged to allow the chamber to be drained regularly. It may be

plumbed into a drain or tundish.

KEEP CLOSED DURING USE & DO NOT OPEN WHEN HOT OR PRESSURIZED.

STEAM HEATED MODELS ONLY

STEAM INLET..

STEAM SUPPLY

This is a 3/8" BSP Screwed Gun-Metal Union. The steam supply should be connected to the gunmetal

union. The STERILIZER may be factory-fitted internally with a pressure reducing valve, .Where fitted

supply pressure should be between 4 and 7 Bar If a Pressure reducing valve is NOT factory- fitted,

steam supply pressure must be reduced to 4 Bar, +0 /- 0.5 Bar with a suitable Pressure Reducing

Valve before reaching the STERILIZER. Please refer to the Rating plate at the rear of the machine for

It is important to fit a pressure gauge into this supply line, after the pressure reduction valve, which will

indicate actual steam pressure available to the machine . A condensate draining steam trap must be

fitted immediately upstream of the STERILIZER, to remove all condensate as Free Water will stop

Sterilizing action.

Steam Supply Problems;-A common fault with installations is that long pipe runs, poor layout or poor

steam quality fill the STERILIZER Chamber up with water. This will be avoided if attention is paid to

Condensate separation. Ensure that the steam supply flow is adequate to feed the machine when

operating - The steam pressure in the line will fall when the machine is HEATING UP .

SUPPLY CONDENSATE RETURN SYSTEM

The steam Supply line must be properly installed. If provision is not made to automatically drain off the

condensate that forms in the supply line the STERILIZER will draw in large quantities of water. this will

stop the Sterilising action, and may cause damage.

Warning ; On new steam systems or those that have cooled beware condensate build-up in lines

which may cause water hammer & damage valves and instruments.

Correct installation and Steam Trap arrangements will avoid this.

STEAM DRAIN OUTLET ( Chamber Condensate )

On Steam Heated Models the Chamber is fitted with an Automatic Chamber Drain. The outlet from

this is the small diameter COPPER pipe at the bottom rear of the machine. It should be connected to a

suitable building drain capable of carrying steam condensate ( at up to 134C ) Connection into the

boiler-house condensate return is not advisable due to the possible bacteriological contamination of

returned condensate if any of the load contaminates the inside of the machine.

This outlet should be connected via an air-break to prevent back-suction.

POWER SUPPLY INLET CABLE

SWIFTCLAVE STERILIZERS are supplied as standard with a fitted Power Supply Cable. Steam heated

Machines have a CEE22 type Power Inlet cable and plug. Electrically heated machines are supplied with

a 5-core or 3-core ready-fitted mains supply cable provided with a standard -type Industrial High-Current

plug. The Cable is of the heavy-duty SY type, Double-Vinyl covered and protected by a woven metal

braid. (Models for 220V 3-phase supplies may have alternative arrangements.)

The STERILIZER has been tested in the configuration in which it is delivered from the factory. Details of

the Supply Voltage and the Current rating, etc are given on the Serial-Number / Rating Plate attached to

the machine.

Cable Alteration

Should it be necessary to alter the supply cable to suit local regulations or arrangements , the new power

supply cable should be arranged in flexible conduit or use similar suitably protected power cable rated to

carry the Maximum Current per Phase for 3-phase machines, and 5 Amps {Single Phase} for Steam

Heated machines. The connections are made to Terminals in the Power Input Box. The Cable should

pass under the lower edge of the rear panel, or through the cutout provided below the Power Input Box,

allowing the panel to be removed for access.

This machine must be wired with a protective earth.

RECORDER POWER FEED

The recorder options include an automatically controlled 240 Volts 1 Amp power outlet via a CEE22

Outlet connector. This is intended to power ONLY an Astell approved Recorder System. Instructions for

use are provided with the Recorder option. Some versions may use a different connector and the output

may also include remote control low-voltage signals.

Do Not Connect Any Other Equipment To This Outlet .
