4700 Refrigerated Sampler
the line to drain, thereby reducing the
possibility of sample cross-contamination. Refer
to Table 1-2 for maximum suction line lengths
and suction head heights.
Security – The location may need to provide
some degree of security to prevent tampering or
vandalism.
Accessibility – The sampler must be installed
in a location where personnel can easily
exchange bottles and perform routine service.
The sampler requires about 2600 square
2
centimeters (925 in ) of floor space. Additional
space must be allowed in front of the sampler,
at its left and right sides, and above the
sampler. Do not block access to these areas.
Obstructions will make routine servicing
activities difficult or impossible.
The back of the sampler may be placed against
a wall as long as air at the bottom of the
refrigerator can flow freely to surrounding air.
Unrestricted air flow behind and around the
sampler will keep the refrigeration system
working efficiently.
Level surface – The sampler should be placed
on a level surface and the feet on the
refrigerator body should be adjusted to prevent
tipping or spills. If the sampler is not level, the
sample liquid may miss the bottle mouth.
To level the sampler, place a bubble level on the
bottle rack or locating base, then adjust the
feet. For one-bottle configurations, place the
bubble level on the side rails of the refrigerated
compartment.
