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

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 .

Neutral. The three pairs of Heater wires are brought to the terminal block in the POWER INPUT BOX ,
labelled as follows:
Wires No 04, 05, 06 or red, yellow, blue group [0] =Heater (NEUTRAL)#1,2,3
Wires No 01,02,03or red,yellow, blue group [3] = Heater (FEED)#1,2,3
POWER SUPPLY CONNECTIONS 380-440 Volt 3-Phase:
16Kw & 12 Kw models with Red-Yellow-Blue power wiring
Power Supply is connected as shown in Appendix 1, Fig.6.
NOTE..THE NEUTRAL LINE MUST NOT BE FUSED.
MODELS FOR 200/240 VOLT 3-PHASE SUPPLY
Export Models For Countries Where Domestic Supply Is 110v Line - Neutral
This Voltage Operation is denoted by Order Code AAN110 or AAN111. These models are not
normally supplied with a fitted power supply cable.
Connect the Power Supply as shown in Appendix 1, Fig.6.
In these models the heaters are the standard (240 volt), 3.3, 4 or 5.2 KW types, wired to operate in 3-
phase DELTA formation. The heater wires are brought to the Contactor in the Power Input Box and
are labelled:-
Wire No. 04, 05, 06 or Red,Yellow,Blue Group [3]= LINE B for Heater #1,2,3

A BALANCED NEUTRAL SUPPLY MUST BE PROVIDED
The internal electronics and control actuators operate from 240 volts supplied by a step-up internal
transformer between Phase 1 and Neutral.
3-Phase Motors are normally dual voltage, wired in delta formation for 200-220v.
Single-phase motors are normally 230V motors wired between two phases. These have fuses in each
supply line.
200-220v 3-PHASE SUPPLIES WITHOUT NEUTRAL
This is option AAN111 . It is electrically as option AAN110 , but requires no Neutral supply.
Connect as described above but omit the Neutral connection.
The internal electronics uses a 220V supply derived from two Phases @ 200-220v via an internal
Isolating Transformer.
CONVERSION
It is possible to convert a SWIFTCLAVE from 380-440 v to 200-220 v supplies or in
reverse. This requires the fitting of a special transformer unit and detailed wiring
changes, and requires the services of a factory-trained qualified engineer.
