Humboldt HM-4160 FlexPanels - Manual (Page 13)

Installation and Configuration
The contents of this section will guide the user through the proper steps
required to safely install and hook up the Panel. This section should be read in
its entirety for first-time installers and reviewed during the installation process.
Equipment Set-up
The first thing, after taking the panel out of the carton, is to place the panel(s)
on a level work surface capable of supporting the unit(s) and providing sufficient
room in which to work and service the panels later. It is advantageous to be able
to walk behind the panel(s) to perform maintenance and check for leaks. Service
lines will need to be run to the rear of the panel and the work space in front of
the panel(s) will need to supply sufficient room for permeability or triaxial cells,
as well as the tubing connecting the cells to the panel(s).
Required Utilities
All panels need the following utilities for operation.
Compressed Air Supply
FlexPanels require a reliable source of clean, dry air of sufficient volume
to supply the Panels‘ bleeding regulators. The minimum requirement is a
compressor that can supply 3cfm at 125 or 150psi with a 30-gallon tank.
As more units are added the capacity of the compressor should be increased
(Some installations may require a 15cfm compressor with a 60-gallon tank).
The air coming from the compressor should pass through a filter system to
remove dirt and entrained liquid in the air line.
Tap Water Supply
Tap water is used to fill the de-aired water tank and run Triaxial quick tests. It is
connected to one of the control panels (HM-4140, HM-4150 or HM-4160) on
the Lower Service Connector Plate. HM-4150A and HM-4160A Add-On Panels
do not have a Tap Water Connector.
De-Aired Water Supply
A source of De-Aired water is required to perform most triaxial permeability
tests. This is usually supplied by the use of a De-Airing tank
Vacuum Supply
FlexPanels need a source of vacuum. This is usually supplied by a small vacuum
pump. Control Panels have a vacuum regulator that regulates vacuum
between 0 and –14.7 PSI (29 in hg, 101 kpa, 760 mm hg). Add-on Panels, which
do not have a vacuum regulator can be a supplied with regulated vacuum from a
Control Panel or unregulated vacuum from the vacuum pump.
Water Drain
FlexPanel operation requires a drain for water used in operation. The Lower
Service Connector Plate has a connector for attaching a drain line to carry away
the liquids released.
