1.6 Installation

Warning

1.6.1 Unpacking

Unpack the HLD5000 immediately after delivery, even if it is to be installed later on.
Examine the shipping container for any external damage. Completely remove the

packaging materials.

Notice Retain the shipping container and the packaging materials in the event of

complaints about damage.
Check that the HLD5000 is complete and carefully examine the HLD5000 visually.
If any damage is discovered, report it immediately to the forwarding agent and

insurer. If the damaged part has to be replaced, please contact the orders
department.

Remove the protection foil from the display.
After switching on the HLD5000 the programmed type of gas has to appear in the

upper left corner of the display and has to match with the sticker on the probe.

1.6.2 Mechanical Connections

In order to operate the HLD5000, a sniffer line must be connected. The connection
(Fig. 2-1/2) is located on the left side on the front of the main unit. Insert the plug into
the opening until it engages. For this the red ma rk o n the p l ug must cor re spon d with
the mark on the main unit.

To disconnect the plug, retract the coupling and remove the probe’s line.

1.6.3 Electrical Connection

The HLD5000 is equipped with a wide voltage ra nge power supply unit cover ing 100
V to 230 V (± 10 %, 50/60 Hz). The mains cord is connected to the mains socket (Fig.

2-1/7) on the rear of the main unit. A fuse (Fig. 2-1/8) for each conductor of the mains

cord has been integrated in the mains socket (Fig. 2-1/7) of the main unit.

Only mains cords having three conductors with a protective ground conductor may
be used. The HLD5000 must never be operated with a disconnected protective
ground conductor.

1.6.4 Wall Mounting

kina40e 01.fm technical handbook(1007)

A fixture at the bottom of the HLD5000 (Fig. 2-2/7) allows mounting the leak detector
on walls, (for example due to space restrictions). It is recommended to place the
HLD5000 high enough (at least 2 m) so that the display points down wards.

General 1-9

1.6.5 RS232 Interface

Caution

The HLD5000 is equipped with a RS232 in terface which is located on the rear of the
main unit under the mains connection (Fig. 1-2). This interface is of the DCE type
(Data Communications Equipment) and allows the connection of a PC for mo nitoring
and data logging. The connection is provided through a commercially available Sub­D plug. For further information see "Interface Description HLD5000” (kins40e1).

1.6.6 The Sniffer Tip

1.6.6.1 Changing the sniffer tip

To change the complete sniffer tip (see Fig. 1-3) loosen the nut connection (Fig. 1-3 )
and pull off the sniffer tip. Insert the new sniffer tip with the guide pin (Fig. 1-3/2)
running in the groove, and firmly retighten the nut.

Ensure, that the filter cartridge (Fig. 1-3/1) is clean, and replace it as required.

Before loosening the connecting nut, you must switch off the HLD5000 first. When
exchanging the sniffer tip make sure th at no dust or particles of dirt enter into the
opening.

1.6.6.2 Use of the flexible sniffer tip

In addition to the rigid sniffer tip included with th e HLD5000, also a 400 mm long
flexible tip (Cat. No. 511-024) may be used. By correspondingly bendin g the flexible
tip, areas which are hard to access can be reached.

1.6.6.3 Use of the sniffer tip extension

For the purpose of measuring refrigerant concentrations (e.g. in the case of already
packaged test objects in the package), for reaching points which are difficult to
access or for finding large leaks quickly a flexible extension (Cat. No. 511-020) may
be screwed onto the filter holder (see Fig. Fig. 1- 3/5). Make sure that the plastic hose
surrounds holder and filter holder. The 400 mm long extension (Fig. 1-3/6) may be
pulled out after pressing down the ring of th e h older ( Fig . 1- 3/8) ; if required , you ca n
cut the extension down to the required length. The tip facing the test object must
always be cut at an angle of approximately 45°.

1.6.6.4 Use of water protection tip

In order to avoid sucking in liquids, the water protection tip (Fig. 1- 3/7) (Cat. No. 511-

025) may be screwed onto the filter holder. The water protection tip will prevent
liquids in up to about 3 mm in he ight (the e.g. puddles of condensed water) fr om
being sucked.

kina40e 01.fm technical handbook(1007)

Fig. 1-4 Water protection tip fitted

General 1-11

In order to prevent the entry of liquids when working on moist test objects, the handle
should not be held vertically with the sniffer tip facing up, this avoids liquids in the
water protection tip from flowing back into the sensor. If, even so, liquid has been

2 Principle of Operation

2.1 Description

The HLD5000 is capable of detecting, measuring and displaying quantitatively the
refrigerant, C0
analyzer.

The important subassemblies of the HLD5000 are:

• the sensor system subassembly located in the probe

• the pump system together with the electric and electronic subassemblies

accommodated in the main unit

Infrared light from a corresponding source is made to pass through a cell through
which also the gas taken in by the HLD5000 flows. This light is filtered so that only
light having a specific wavelength is allowed to pass on to an infrared light detector.

If in the presence of a leak, refrigerant, SF
cell, the infrared light is partly absorbed by the refrigerant. The intensity of the light
arriving at the detector is thus reduced.

The change in the intensity of the light is amplified electronically, converted from
analogue to digital and is displayed visually and audibly after processing by the
microprocessor in the main unit. By means of a reference measurement based on
the ambient air, the background concentration of the test gas or other interfering
gases is taken into account when processing the measured data.

3.1 Start-up

Put the HLD5000 in place (see also chapter wall installation), connect the sniffer line
and the mains cord.

The HLD5000 will only operate after having connected the sniffer line first.

Do not place the HLD5000 on hot surfaces.

Notice In the default setting the serial numbers of the main unit and the probe has

to match.
Press the mains switch (Fig. 3-2/6) to switch on the HLD5000. The HLD5000 will take

about 30 seconds to warm up as indicated by the display.

During warm-up the sniffer tip must not be inserted in the test leak opening.
Otherwise, the internal calibration will be disabled and an error message will be
displayed.

In the default setting, the HLD5000 uses English menu text. To switch to another
language press the keys
the chosen language and confirm with “OK”.

After the warm-up phase of the HLD5000, an audible signal is produced and the leak
detector will be ready to make measurements. The green LED (Fig. 3-3/2) in the
probe indicates that the HLD5000 is ready to make measurements. The type of gas
to which the HLD5000 has been programmed as well as the un it of measurement for
the leak rate (factory default: g/a) is indicated on the display (Fig. 3-2/4). Moreover,
the type of probe (detectable gas) to which the HLD5000 has been set up is indicate d
on the sticker on the probe.

The main unit is usable for all refrigerants, the detectable refrigerant is determined
by the probe.

3.2 Working with the HLD5000

Warning

Caution

Provided the HLD5000 has been adapted to the specific requirements of the
application (see Chapter 4) and calibrate d accordingly, a le ak test can be per formed
as follows:

Lead the probe tip as close as possible to the locations that are to be tested. If
needed, the tip may even touch the unit under test.

Danger of electric shock.

• Do not touch live parts with the sniffer tip.

• Test samples need to be disconnected from electricity before leak testing.

Under all circumstances the intake of liquids which may still be present on the
surface of the test object has to be avoided.

In the case of moist test objects (e.g. condensed water) the use of the water
protection tip is recommended (see Chapter 1.6.6).

If a welded seam or a joint needs to be tested, the tip of the probe should be moved
no faster than 2.5 cm/s (1 inch/s) across the location which is to be tested. The
distance between probe tip and unit under test should be kept as small as possible.
In the case of probing a specific location, the tip should remain in place briefly (at
least 1 s).

The HLD5000 compares the measured leak rates with the rejection leak rates
(trigger levels) set up as described in Chapter 4.1. If the measured leak rate exceed s
the rejection leak rate, then more than half of the yellow lamps (LED) on the arc­shaped display (Fig. 3-2/5) will come on and an audible alarm is released.

Due to its working principle (see Chapter 2.1) background concentrations in the
environment are suppressed and do not cause an alarm. Refrigerant clouds in front
of large leaks will also be considered a background concentration. Different from the
behavior of its predecessor HLD4000, the HLD5000 will not alarm when only
approaching leaks from a larger distance. Larger leaks will also only be detected
when close to the leak and thus, can be localized reliably.

Notice If you can not guarantee getting close enough to the leak (as described

above) larger leaks may be missed. In this case, please use the flexible
sniffer tip extension (Cat. no. 511-020) which is delivered with the
HLD5000. For this application the extension tip can be cut down to 100 mm
(4 in.) length for easier handling. (see Chapter 1.6.6.3)

Depending on the measurement mode (see Chapter 4.1) the test should be repeated
with the key of the probe pres sed to precis ely pinpoint the location of the leak or to
double check the rejection leak rate.

A calibration can be checked by inserting the probe tip into the calibration port
without depressing the button on the probe. A message will be displayed indicating
whether or not the calibration is still OK (refer also to Chapter 4.1.4, manual
calibration).

On the leak rate display, two LEDs to the left and right of the 100% mark will flash. If
the measured value is outside this mark, a recalibration will be required. The
currently measured value is indicated by two moving LEDs just like during the
calibration process. Moreover, the calibration status is indicated on the display.

A recalibration can be started immediately by pressing the button, and the probe tip
does not have to be removed from the calibration port.

If a recalibration is required, this is indicated on the display and by an audible tone.
During the check, the probe must be held still and straight.

4.5.2 Calibrating the HLD5000 with the COOL-Check

To calibrate the HLD5000, press the button on the probe and insert the sniffer tip into
the calibration port at the front of the main unit. The HLD5000 will then start the
calibration process automatically. During the calibration process it is not necessary
to keep the button on the probe pressed. The individual phases of the calibration
process are indicated on the display which also informs the user about a successful
calibration.

Notice During the calibration process, the probe must be held still and straight,

otherwise no calibration will be possible.

Notice During the calibration, the opening for the calibrated leak should not be

exposed to strong air flows (from air-conditioning units, for example).

Notice When performing the calibration using the extension tip Cat. No. 511-020

the insert should be used in the opening of the calib r at ed leak so as to
ensure that the tip is properly centered in the opening.

How to replace the COOL-Check is described in Chapter 6.2.5.

Notice Replacement leaks should not be purchased in advance of their need as

they have a limited lifetime.

4.6 Shutting Down

The HLD5000 may be switched off at any time by operating the mains switch
independently of the operating mode it is in.

All parameters are saved when the HLD5000 is powered down.

4.7 Switching probes

To convert the HLD5000 to a different probe shut down the HLD5000, unplug the
current sniffer line and connect a different sniffer line with a different probe. The
probe type will be indicated in the upper left corner of the display after restarting the
HLD5000.

While operating in the leak detection mode, the display will provide information which
will support the operator using the HLD5000. Besides messages relating to leak
detector settings also warnings and error messages may be displayed.

The HLD5000 is equipped with comprehensive self-diagnostic means. If a fault
condition is detected by the controller board this is indicated via the display to the
operator.

Errors are events which force an interruption to the measurement sequence and
which the HLD5000 is not capable of remedying on its own. Errors are displayed in
plain text on the display. The error sound is a two-tone sound.

The error message can be erased by pressing the "OK” key.
As long as an error status exists, a warning triangle comes up in the lower line of the

display.
An overview over the error messages which may occur while the machine is in use

and possible remedies are listed below.
A list of all error messages as well a notes for troubleshooting is provided in the

Repair Instructions (kipa40e1).

6 Maintenance

6.1 INFICON Service

If an the HLD5000 is returned to INFICON, please indicate whether it is free of
substances damaging to hea lth or whether it is contamin ated. If it is contaminated
also indicate the nature of the hazard. For this you must use a form pre-prepared,
which we will send to you upon request or which you may copy from this manual.

The form is called: "Declaration of Contamination of Vacuum Equipment and
Components”.

Affix this form to the HLD5000 or enclose it with the leak detector. This Declaration
of Contamination is required by us to meet the requirements of the laws and to
protect our staff.

INFICON will return any leak detectors without a "Declaration of Contamination" to
the sender’s address.

6.2 Maintenance Work

No fixed maintenance intervals have been specified for the HLD5000. The work
described in the following will only have to be done as required.

6.2.1 Replacing the Filters

The filters serve the purpose of filtering the air taken in. In order not to obstruct the
airflow and to prevent the HLD5000 from being contaminated all filters should be
exchanged preventatively.

There are three filters in the HLD5000, two within the sniffer tip filtering the air intake
through the sniffer line and one air filter at the bottom of the housing.

6.2.1.1 Exchanging the filters in the sniffer line

We recommend to exchange the filter holder at the probe tip preventatively at least
once a week and the filter cartridg e at the bottom of the sniffer tip at least once a
month.

If the function “Request for filter replacement“ is enabled, the message „Please
replace filter holder!“ will be displayed every 40 hours of operation. After replacing
the filter holder and acknowledging the message the internal counter for this function
will be reset and the message will pop up after another 40 hours of operation. Any
dirty or clogged filter in the sniffer line will lead to the same error message as a dirty
tip filter holder. In dirty conditions the error message “flow at measuring line too low”
or “flow at reference line too low” may occur before expiration of these time limits. On
occurrence of these error messages please exchange the tip filter holder first. If this
does not fix the problem, please also exchange the filter cartridge.

kina40e 06.fm technical handbook(1007)

Maintenance 6-1

Caution

Before exchanging any of the sniffer line filters please switch off the HLD5000.

Caution

When replacing filters please make sure that no particles enter into the intake
opening.

The fine filters at the probe tip are firmly built into the filter holder. To replace the filter
holder please:

1 Unscrew the filter holder from the probe tip
2 Screw on a new filter holder.

Replacement filter holders are available for order in sets of 20 pieces as
Cat. No. 511-027.

The fine filters at the bottom of the sniffer tip are firmly built into the filter cartridge.
To exchange the filter cartridge please:

1 Loosen the screw at the bottom of the sniffer tip and detach the sniffer tip from the

probe handle

2 Take off the filter cartridge from the bottom of the sniffer tip
3 Place a new one on the two ends of the measurement and reference line
4 Attach the sniffer tip back onto the probe handle and retighten the screw at the

bottom of the sniffer tip.

Replacement filter cartridges are available for order in sets of 20 pieces as Cat. No.
511-018.

5 Exchanging the air filter at the bottom of the housing.

The air filter at the bottom of the housing sh ould be replaced once it has turned dark
gray or deposits of dirt are clearly visible on the filter.

Before replacing the air filter at the bottom of the housing please disconnect the
HLD5000.

1 Switch off the HLD5000 off and pull the mains plug
2 Unscrew the screws in the middle of the filter
3 Remove the filter and depending on how dirty it is either replace it or clean it (for

example with compressed air or a brush)

4 Insert the filter once more
5 Tighten the screw

Replacement air filters are available for order as Cat.No. 200 000 086.

6-2 Maintenance

6.2.2 Cleaning the Opening of the Calibrated Leak

Warning

In order to prevent the light barrier in the opening of the calibrated leak from being
interrupted by dirt, the opening should be blown out with clean compressed air
regularly.

6.2.3 Cleaning

The housing of the HLD5000 is made of plastic. Therefore to clean the housing use
cleaning only agents which are recommended to clean plastic surfaces (for example
mild household cleaning agents). Do not use any solvents which attack plastic
materials.

6.2.4 Replacing Fuses

To replace the fuses remove the mains cord first.

The fuse holder (Fig. 2-2/8) of the HLD5000 is located below the ma ins socket on the
rear of the main unit. To replace the fuses proceed as follows:

1 Press down the pin in center and pull the fuse holder out.
2 Pull the fuses out and check these.
3 If required insert a new fuse. In any case two fuses of the same rating will have to be

inserted. The mains fuses required are slow-blow T 1 A (Ø 5 x 20 mm).

4 Insert the fuse holder once more and press it home until the securing pin engages.

After having replaced the fuses, reconnect the mains cord to the HLD5000 and
switch on the leak detector.

6.2.5 Replacing the Calibrated Leak (not for SF6 / CO2 version)

The calibrated leak should be rep laced two to three months at the latest after the
message " Leak nearly empty. Please replace!” has been displayed. The calibrated
leak is replaced as follows:

1 Switch off the HLD5000 off and pull the mains plug.
2 Turn the main unit on its side to expose the base.
3 Turn the yellow plastic screw back completely.
4 Carefully remove the calibrated leak. Don’t damage the cable.
5 Pull off the plug (blue) from the calibrated leak’s printed circuit board.

kina40e 06.fm technical handbook(1007)

6 Take a new calibrated leak and insert the plug into the socket.

Maintenance 6-3

7 Insert the new calibrated leak and feed the cable with the plug through the hole.
8 Secure with the screw. Please make sure that the rubber seal is firmly in place and

that the outlet opening of the calibrated leak is positioned approximately at the
middle of the opening for the calibrated leak.

9 Switch off the HLD5000 on and run a new calibration after about 5 minutes.

A residual amount of refrigerant might be left un der pressure (more than 5 bar) in the
canister of the empty leak standard. Therefore the COOL-Check must be disposed
PROPERLY - following the local, state and national regulations - or must be sent
back to INFICON / your supplier.
