1.0 INTRODUCTION
The Liebert Liqui-tect Monitoring System is the ultimate in leak detection and retrofitting capabili-
ties for computer rooms and other large areas. The Liqui-tect Monitoring System provides direct-read
at the control unit location, as well as the ability to communicate with the Liebert SiteScan Web
enterprise monitoring system or a building management system.
The Liqui-tect Monitoring System features an easy-to-use liquid crystal display (LCD) panel with
readout of normal and alarm conditions, as well as leak location. Display and measurement modules
are contained in a single compact package.
The Liqui-tect Monitoring System can monitor up to 10,000 ft. (3048m) of Liebert LT500Y leak detec-
tion cable. Points along the cable may be mapped by one person, making it easy to configure within
the critical space and pinpoint the location of leaks when they occur. The system determines the loca-
tion of the water on the detection cable and reports the distance from the Liqui-tect panel in feet or
meters. To ensure proper protection, the system continuously monitors operation, signaling system
normal, leak detected and cable fault.
The Liqui-tect panel offers these and other features to protect your installation from leak damage:
• audible and visual alarms
• adjustable sensitivity setpoints for leaks and contamination
• continuous scrolling of data
• history logs
• connection to a building management system
• automatic detection of broken cables and contaminated cables
• password protection
• retention of configuration after a power failure
Two interfaces permit easy access and configuration of the Liqui-tect panel:
• LCD on the front of the enclosure
• Liebert’s SiteScan Web enterprise monitoring system through a dedicated connection port
1.1 Equipment Inspection
Upon arrival of the unit, inspect all items for visible and concealed damage. Damage should be imme-
diately reported to the carrier and a damage claim filed with a copy sent to Liebert or to your sales
representative.

1.2 Outside Enclosure Overview
The enclosure for the Liqui-tect panel’s controller board comes in two sizes:
•Thelarge enclosure is designed to accommodate the Transformer Module and future compo-
nents, in addition to the controller board.
•Thesmall enclosure is built to hold the controller board only.
Both enclosures are 2-3/4" deep.
Both enclosures have a built-in liquid crystal display (LCD) and a key lock, as shown in the example
below. The metal enclosures accommodate secure conduit fittings and protect components against
external forces and debris.
Figure 1 Small enclosure—external features
The enclosure must be secured to a wall, either flush-mounted or recessed in the wall, as described in
2.0 - Installation. Knockouts and access slots on the top and bottom allow easy connection of wires
and cables (see 3.0 - Connections and Configuration) with either mounting type.

2.0 INSTALLATION
2.1 Installation Considerations
The Liqui-tect panel must be installed indoors and may be mounted on the surface of a wall or flush-
mounted, depending on the user’s application and the type of wall the unit will be mounted on. The
unit’s location must meet the following criteria:
• The panel must be placed close enough to the areas to be monitored to permit proper connection of
the leak detection cable. The panel will monitor two zones; each zone can accommodate up to
5,000 ft. (1524m) of leak detection cable.
• The Liqui-tect panel should be mounted where it can be easily accessed. Personnel would access
the unit through the LCD on its front cover or through SiteScan.
• The site also must have electrical service and must permit connection of the panel’s four digital
outputs, two inputs for leak detection cables and two analog outputs for connecting to a building
management system or external alarm.
• The wall material must be capable of supporting the weight of the Liqui-tect panel: see 7.0 -
Specifications.
2.1.1 Unpacking and Preliminary Inspection
• Before unpacking the Liqui-tect panel, inspect the shipping carton for damage or signs of mishan-
dling, such as gashes or holes in the carton or severely flattened corners.
• Open the shipping container carefully. Use care to avoid puncturing the container with sharp
objects that might damage the contents.
• Inspect the Liqui-tect panel and all included components for damage.
• If any damage from shipping or mishandling is observed, immediately file a damage claim with
the shipping agency and forward a copy to:
Liebert Corporation
1050 Dearborn Drive
P.O. Box 29186
Columbus, OH 43229

2.2 Surface-Mounting the Liqui-tect Panel
After determining where to place the unit, check to ensure that you have all the hardware required to
install the panel on the surface of a wall. Obtain the needed tools and material.
Required tools
• Electric drill (if surface is too hard to drive screws without pilot holes)
• Screwdriver
• Marker to denote layout of holes
• Four screws, each #10
2.2.1 Mounting the Panel
1. Mark the wall for mounting holes, using the back of the unit as a template (see Figure 4).
2. Drill holes, if required, to install the four #10 screws that will secure the Liqui-tect panel to the
wall. Clean up the debris.
3. If the wall material is not strong enough to hold the screws securely, use wall anchors.
4. Install the top two screws—the screw heads must be small enough to slip through the larger,
bottom portion of the pear-shaped mounting slot in the Liqui-tect panel (see inset in illustration
at right). The screws must also be large enough to extend over the edges of the top of the
mounting slot.
5. Hang the Liqui-tect panel on the screws, letting the panel slip down until the screws are in the
smaller, upper portion of the slot.
6. Tighten the screws until they are snug.
7. Insert the remaining two screws in the bottom holes on the back of the panel and tighten.
Figure 4 Mounting dimensions
NOTE
Removing the conduit knockouts before mounting the Liqui-tect panel on the wall will ease
installation and prevent strain on the mounting hardware and wall. It is imperative to remove
the knockouts if the unit is to be flush-mounted.
!CAUTION
Check building plans and other relevant documents to determine whether mounting the
Liqui-tect panel at the selected location might cause cutting or otherwise damaging electrical

2.3 Flush-Mounting the Liqui-tect Panel
The Liqui-tect panel may be flush mounted according to company practices—either with screws
through the sides of the panel into wall supports or with hanging hardware that attaches to the back
of the panel. After determining how and where to place the unit, check to ensure that you have all the
hardware required to install the panel in the wall. Obtain the needed tools.
Required tools
•Saw
• Electric drill
• Screwdriver
• Marker to denote layout of the hole to accommodate the Liqui-tect panel
• Trim ring and associated hardware
• Mounting hardware
2.3.1 Mounting the Panel
1. Mark the wall for the cutout to accommodate the panel, using the back of the unit as a template.
2. Drill a pilot hole for the saw blade, if required.
3. Use the saw to cut out the marked section of the wall (if not new construction).
4. Rest the Liqui-tect panel in the wall and mark where mounting screws will be inserted into the
wall studs or other support member.
5. Remove the panel and drill the holes for the mounting screws or wall anchors. Clean up the
debris.
6. Reverse the slide direction of the rectangular access doors on the top and bottom of the Liqui-tect
panel. Leaving the access doors as shipped from the factory prevents them from being opened
when the panel is flush mounted in a wall.
7. Attach any field-supplied mounting hardware.
8. Reinsert the assembly into the wall.
9. Insert and tighten the screws or wall anchors.
NOTE
Removing the conduit knockouts before mounting the Liqui-tect panel on the wall will ease
installation and prevent strain on the mounting hardware and wall. It is imperative to remove
the knockouts if the unit is to be flush-mounted.
The rectangular access doors on the top and bottom of the Liqui-tect panel must be removed
from the outside of the panel and reinstalled on the inside of the panel. Leaving the doors as
shipped from the factory prevents them from being opened when the panel is flush mounted in
a wall.
!CAUTION
Check building plans and other relevant documents to determine whether mounting the
Liqui-tect panel at the selected location might cause cutting or otherwise damaging electrical
or communication wiring or pipes.

2.4 Connect Power to the Liqui-tect Panel
The Liqui-tect panel requires 24VAC for proper operation. Liebert recommends using the optional
Transformer Module manufactured by Liebert or another UL-approved Class 2 power unit to obtain
proper voltage. If the power unit is not a Class 2 circuit, it must be protected with an IEC 5 x 20mm
time lag 2A fuse. For information, consult your local dealer, Liebert representative or the Liebert
Worldwide Support Group.
2.4.1 Input Power Connections - Small Enclosure
To connect electrical power:
1. Run conduit and electrical wiring from building to the Liqui-tect panel.
2. Use copper wires only; proper wiring to use for 24VAC power is 18-22 AWG stranded and shielded
(18 AWG is recommended—see Table 4). Strip wires 1/2".
Figure 5 Electrical connections to panel
3. Secure the incoming electrical service wires to the Liqui-tect panel’s 24VAC input by sliding the
wires into TB1, the 24VAC input terminal block. There is no polarity requirement when
connecting to TB1. The ground wire must be connected to the earth ground terminal located on
the side of the panel (see Figure 5).
!WARNING
Check that power is removed from wires prior to installation.
!CAUTION
The Liqui-tect panel is designed for use on properly grounded (earthed) 24VAC power, 50Hz
or 60Hz. The ground wire for the power lead must be wired to the earth ground terminal (stud
located next to the 24VAC terminal block).
This equipment is intended to be installed by a qualified and certified electrician who must
review and approve customer supplied wiring and circuit breakers, verify correct input and
grounded (earthed) connections to ensure compliance with technical standards and national
and local electrical codes.
!WARNING

3.1 Connecting Leak Detection Cable Inputs
The leak detection cable inputs are found on the lower right side of the Liqui-tect panel’s printed wir-
ing assembly board. There are two terminal blocks for the inputs; the lower terminal block is for the
Zone 1 cable and the terminal block above it is for a second leak detection cable, Zone 2.
To determine the proper wire size, see Table 4 - Wiring specifications.
3.1.1 Attaching Leak Detection Connection Cable to the Panel
To attach a leak detection connection cable:
1. Disconnect electrical power to the Liqui-tect
panel.
2. Locate the Zone 1 and Zone 2 cable connectors
on the controller board. They can be found on
the lower right corner of the board (see 1.4 -
Controller Board Overview). The Zone 1
connector is Cable 1 or TB9. The Zone 2
connector (Cable 2 or TB6) is just above it.
3. If necessary, remove a conduit knockout to
permit wire entry into the Liqui-tect panel
enclosure.
4. Bring the white connection cable
(CONNECT10) into the Liqui-tect panel
enclosure through a conduit knockout or
access slot.
5. Loosen a screw on the terminal block and slip
the stripped end of the appropriate wire into
the terminal block according to the color-coded
wiring key (see illustration at right).
Note that the WHITE wire connects to the “Y”
slot. The red wire connects to the “R” slot, the
green wire connects to the “G” slot and the black wire to the “B” slot.
6. Tighten the screw until it holds the wire snugly.
7. Repeat for each of the four wire strands in the connection cable.
NOTE
Each terminal block is a removable, two-part assembly to permit easier connection of more
than one input at a time. If making multiple connections, grasp the upper portion of a block
and pull firmly to the right until the assembly pulls apart.
After making the connections, push the removed piece back into the portion attached to the
printed wiring assembly until the terminal block pieces lock together.

3.1.2 Connecting Leak Detection Cable to the Connection Cable
The connection cable has a black fitting on one end that will fasten securely to the fitting on one end
of the leak detection cable—see Figure 8. Push these ends together, being careful to insert the pro-
truding ends of the leak detection cable into the holes in the connection cable connector. Twist the
connector ring to securely link the cables.
Figure 8 Fittings on leak detection cable (LT500Y) and connection cable (CONNECT10)
After making this connection, lay the leak detection cable around the area to be monitored.
The monitored area would include any equipment or objects that might be damaged by water.
Figure 9 shows one possible layout. In the example, the detection cable crosses between air condi-
tioning units and computers to alert personnel when the electronic equipment is threatened by a leak.
If there is a liquid source in the ceiling, the cable can be placed there. If a raised floor is used for cool-
ing, the cable can be placed underneath the raised surface.
Figure 9 Typical leak detection cable layout
Follow these steps in laying the detection cable:
1. Attach the end terminator to the last length of leak detection cable required to monitor the
selected area.
2. Verify power is connected and test the detection cable by touching the detection cable with a
clean, moist cloth or paper towel.
If the cables are connected properly, the audible horn should sound and the LCD screen should
flash. Dry the detection cable to remove the alarm condition. (A hair dryer can be used to speed up
the drying.)
Note: Do not try to saturate the detection cable for testing! It requires only a small amount of
water to alarm. The detection cable will have to dry for the alarm condition to clear.
NOTE
Make sure the male end of the LT500Y leak detection cable is installed close enough to the
Liqui-tect panel to reach the fitting on the CONNECT10 connection cable.

3. Once the cable passes the test, lay it in the pattern desired. Pay special attention to the following
cable placement precautions.
4. Install the hold-down clips in pairs, as shown in Figure 10, with the following considerations:
a. The adhesive used to install the hold-down clips must NOT come in contact with the detection
cable.
b. One pair every 6 to 8 ft. (1.8-2.4m) in straight patterns (see Figure 11).
c. One pair every 3 to 4 ft. (0.9-1.2m) in circular patterns (see Figure 12).
d. One pair at the beginning and end of the arc when turning 90 degrees (see Figure 13).
e. One pair as needed to maintain consistent uniform contact between the floor and detection
cable.
5. Once adhesive is completely dry, snap the cable into each hold-down clip.
6. Check that there are no gaps between the floor and detection cable. (Add clips as required.)
7. Be certain there are no alarms present on the module.
8. Do final testing as per instruction in Step 2.
DETECTION CABLE PLACEMENT PRECAUTIONS
• Do not use detection cable that is damaged or dirty—for example, from plaster, spackle or debris.
• Detection cable should not be dragged through contaminants (dirty or greasy areas). Floor must be clean
for the detection cable to function properly and for the hold-down clips to adhere to the floor surface.
• Careful consideration should be taken to place detection cable out of the direct discharge airflow path of
environmental equipment. This type of equipment can discharge moisture into the airflow. Place cable
6 ft. (1.8m) from discharge to avoid nuisance alarms during humidification.
• Tools or heavy objects can do permanent damage when dropped, rolled, or set on the detection cable.
Avoid foot traffic on the detection cable as well.
• Do not use any type of adhesive tape to secure the detection cable.
• Do not allow soldering or welding near the detection cable without providing protection from heat and
contaminants. (Also avoid installing the detection cable in or near these type of areas.)
• Mild dishwashing liquid can be used to clean the detection cable of many contaminants.

3.2 Connecting Alarm Outputs
The Zone 1 and Zone 2 alarm outputs, found in the top right corner
of the Liqui-tect panel, provide a contact output for a leak and a
cable break for each zone. As an example, the outputs may provide
alarms to an auxiliary alarm panel or building management sys-
tem. To determine the proper wire size, see Table 4 - Wiring spec-
ifications.
A wiring key beside each terminal block indicates whether the con-
nected output is wired for Normally Open (NO) or Normally Closed
(NC).
An alarm relay wired as an unsupervised point (energized for
alarm) must be wired to the Normally Open (NO) and Common (C)
contacts.
An alarm relay wired as a supervised point (de-energized for alarm)
must be wired to the Normally Closed (NC) and Common (C) con-
tacts.
To connect an output:
1. Disconnect electrical power to the Liqui-tect panel.
2. If necessary, remove a conduit knockout to permit wire entry into the Liqui-tect panel enclosure.
3. Bring the wire(s) into the Liqui-tect panel enclosure through a conduit knockout or access slot.
4. Loosen the appropriate screw and slip the stripped end of the wire into the terminal block.
5. Tighten the screw until it holds the wire snugly.
3.3 Connecting to a Building Maintenance System or External Alarm System
Two analog output connector blocks permit the user to connect aux-
iliary notification equipment to monitor the distance of the leak and
cable fault alarms. The terminal blocks are on the right side of the
Liqui-tect panel printed circuit board, just above the leak detection
cable connectors. To determine the proper wire size, see Table 4 -
Wiring specifications.
To connect an input:
1. Disconnect electrical power to the Liqui-tect panel.
2. If necessary, remove a conduit knockout to permit wire entry
into the Liqui-tect panel enclosure.
3. Bring the wire(s) into the Liqui-tect panel enclosure through a conduit knockout or access slot.
4. Loosen the appropriate screw and slip the stripped end of the wire into the terminal block.
5. Tighten the screw until it holds the wire snugly.
