Operating The Instrument - Ametek CHANDLER ENGINEERING 5265 Instruction Manual

Operating the Instrument

1. Install the Model 5270 Data Acquisition Software in accordance with the instructions found in the
software manual.
2. Connect power to the instrument using the cord and twist-lock connector supplied with
the autoclave. It is recommended that each individual autoclave be connected to a
separate circuit breaker or fuse. A 15A fuse or circuit breaker is recommended. A
separate power input exists for the internal electronics. This arrangement permits the use
of an uninterruptible power supply (UPS) to protect the data acquisition electronics and
test data from brief power failures.
3. Connect the coolant to the connector labeled COOLANT INLET on the rear panel of the
instrument as shown previously. The fitting is a 1/4-inch female NPT fitting. If water is
used for cooling, the water must be clean and free of debris that could cause failure of the
pump or relief valve. If in doubt, a water filter is recommended.
4. If the optional chiller is being used, connect the outlet port of the chiller system to the
COOLANT INLET port and the COOLANT DRAIN port to the chiller inlet port.
Configure the chiller to operate at the minimum set point temperature (41 ° F, 5 ° C).
5. Connect the pressurizing water to the connector labeled PUMP WATER INLET on the
rear panel of the instrument as shown previously. The fitting is a 1/4-inch female N.P.T.
fitting. The water must be clean and free of debris that could cause failure of the pump or
relief valve. If in doubt, a water filter is recommended.
6. Connect the water drain line to the connector labeled PUMP WATER DRAIN on the rear
panel of the instrument as shown previously. If water is used as a coolant, the
COOLANT DRAIN may also be connected to the water drain line. If an external chiller
is used, the COOLANT DRAIN is connected to the chiller return. The fittings are 1/4-
inch female NPT fittings.
The drain system must be capable of handling hot water up to 212 ° F (100 ° C) or brief
surges of up to 400 ° F (204 ° C) steam for short periods of time during initial cooling of the
instrument. If two or more autoclaves are connected to a common drain line, it is
recommended that the common drain be 3/8-inch (10mm) inside diameter, minimum. It
is also recommended that the drain system be all metal. Copper tubing with brass fittings
is satisfactory.
7. Connect the air supply to the connector labeled AIR INLET on the rear panel of the
instrument. The fitting is a 1/4-inch female N.P.T. fitting. The air should be dry and
relatively free from dirt and oil. The air should be supplied at a pressure of 50-100 psi
(340-690 kPa). Compressed nitrogen may also be used in place of the compressed air if
necessary.
