Installation Tests

At the time of installation, before the autoclave can be okayed for

daily operation the service technician needs to perform the

following preliminary checks:

♦

Integrity check:

perform a visual check to verify that there are no

dents, scratches or broken components on the autoclave

♦

The leakage current check:

test the precise operation of the earth

leakage relay

♦

Ground check:

test the continuity of the grounding connection

♦

Power supply check:

check that proper power is being supplied to

the machine. See sec. 3.4.

♦

Pitch check:

confirm that the autoclave has a downward pitch back

to front of 1/8" per foot. (see sec. 3.5)

♦

Exhaust and Feed hose check:

ensure that all hoses are free

flowing and not restricted.

♦

Water Pressure Check:

verify that the city water pressure into the

unit is between 15 - 58 psi. Verify that the mineral free water

pressure into the unit is between 7 - 30 psi.

♦

Door check:

ensure that the door locking mechanism is

functioning properly

♦

Reset the Unit:

turn power off using the green power button at the

bottom of the front panel, press and hold the Sel. Cycle button on

the keypad, turn power on, continue to hold the Sel. Cycle button

until the message

Program Wait

appears on the screen.

♦

Atmospheric Pressure check:

the unit is set from the factory at

14.5 psia, this is atmospheric pressure at sea level. If the unit is

located more that 500 ft above or below sea level then the Atmos.

Press parameter must be set, see sec 8.2.17

♦

Safety Valve check:

test the safety valve as per the instructions in

sec 8.6 of the Operator's Manual

♦

Cycle check:

run a B&D Test to ensure that all systems in the unit

are functioning properly.

After the above steps are performed, the autoclave is ready for

daily operation
