Note: Comply with all the items in this section prior to operation.
CoreLok
Bags.
Use only bags that are provided by InstroTek,
Inc. Polymer bags should be handled with
care. Small holes can develop in bags that are
mistreated and render them useless for
effective sealing. During transportation, store
the bags in a safe, protected place. Bag sizes
are critical for optimum vacuum operation.
Two different size puncture-resistant bags are
provided for use with both small and large
cores.
For all 4” cores and for 6” cores up to 2”
thick, use the small bags (10” X 14”).
For all other large sizes, use the large
bags (15” X 18”).
For special sample types and shapes,
contact InstroTek, Inc.
Bag color may vary depending on the date of
manufacture.
SEAL
The SEAL time is set at the factory for 1.0
seconds, however, this may be adjusted by
the user if there is evidence that bags are not
sealing completely or the bags are melting
beyond the needed SEAL time. To change this
setting press the MENU button until “SEAL 1.0” is
displayed on the screen, use the UP or DOWN
arrow buttons to extend or shorten the SEAL
time, finally press the MENU button to return to
the PROGRAM# screen
Stop
Before operating, check proper oil level. See
Illustration on page 39. Oil level should register
between ½ and ¾ level on the pump sight
glass visible by removing the stainless steel
housing. Operation of the pump, even for a
few seconds, without oil can cause extensive
wear and damage. If oil needs to be added,
refer to the Maintenance section of the
Operator’s Guide.
