1.1 General Product Information

1.1.1 Product/System Description

Liebert’s XDP refrigerant distribution unit is an interface between the building chilled water system
and the cooling modules in the Liebert XD system. It is designed to circulate and control refrigerant
to the cooling modules that are in the room with heat-producing equipment. The Liebert XDP is rated
for 160kW (546,000BTU/H) of cooling.

The Liebert XDP consists of a cabinet that includes a heat exchanger, circulating pump(s), control
valve, receiver, controls, valves and piping.

The Liebert XDP monitors room conditions and prevents coil condensation by maintaining the
refrigerant being pumped to the cooling modules at a temperature above the room’s dew point.

All functions, such as switching pumps (if applicable), controlling refrigerant temperature, etc., are
automatic.

Product Description

1.1.2 Minimum Load

1.2 Equipment Inspection

The Liebert XDP's minimum recommended operating load is 30% of system nominal capacity. The
Liebert XDP160 is rated for 160kW (546,000BTU/H) of cooling, therefore the system's minimum
recommended load is 48kW (163,800BTU/H). Loading below this value can unfavorably affect system
operation. Consult the factory for any loading below this recommendation.

To achieve the minimum recommended load, the capacity of all connected modules must total at least
48kW (163,800BTU/H). See

2.4 Remote Sensor Installation—Proper Placement

Placement of the two remote temperature/humidity sensors is critical to effective cooling of the
conditioned space.

The remote sensors must be installed in areas where conditions are representative of the space
conditioned by the Liebert XDP. Emerson recommends installing the sensors in different areas near
the cooling modules served by the Liebert XDP. If the return air side of the primary air mover, such
as a Liebert DS, represents the conditions where the Liebert XD cooling modules are located, one
sensor could be placed there. Emerson suggests placing the other sensor on the wall opposite the heat
load area (see

Do not install the sensors where ambient air might cause false readings, for example, near unsealed
doors or windows, or areas with stagnant air.

1. Unpack the two remote temperature/humidity sensors and cables.
One sensor is labeled Sensor A and the other Sensor B. The sensor cables are interchangeable;

each bears labels indicating Sensor End and Unit End.

2. Connect the Sensor End of one of the supplied sensor cables to P66 on Sensor A (see Figure 14).

3. Connect the Unit End of the sensor cable to P67 on the Liebert iCOM input/output board inside
the Liebert XDP. Secure the ring terminal on the cable shield to the electric box adjacent to P67
(see

4. Connect the Sensor End of the second sensor cable to P66 on Sensor B (see Figure 14).

5. Connect the Unit End of the cable to P67 on the Liebert iCOM display (see Figure 14). Secure the
ring terminal on the cable shield to the grounding screw adjacent to P67.

3.1 European Union Fluorinated Greenhouse Gas Requirements

Stationary air conditioning, refrigeration, heat pump equipment and stationary fire protection
systems in the European Community market and operating with fluorinated greenhouse gases (f­gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F­gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the
atmosphere.

The F-Gas Regulation requires operators to use all measures that are technically feasible and do not
entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to
recover f-gas before disposing of equipment, as well as during service and maintenance.

Refer to the full regulation for additional details.

3.2 Connection Sizes

The copper pipe connections on the Liebert XDP are:

Building Chilled Water Supply 2-5/8" OD

Building Chilled Water Return 2-5/8" OD

Refrigerant Supply 1-1/8" OD

Refrigerant Return 2-1/8" OD

Piping

3.2.1 Recommended Pipe Size

Connect the main pipes between the Liebert XDP and the Liebert XD cooling modules according to
site specific documentation and the configuration guide for the Liebert XD system.

Elbows and restrictions must be minimized to get good fluid flow.

SLOPE—The main supply and return lines to and
from the Liebert XDP must be sloped downward
toward the Liebert XDP at a rate of 1-2" per 20 feet
(25.4-51mm per 6m) of pipe run.

All supply and return
mains must be level
with or above the
top of all Liebert XD
modules

All piping must be ASTM (American Society for Testing and Materials) Type ACR copper pipe.
The Liebert XDP may be connected to Liebert XD cooling modules with either Liebert’s XD

prefabricated piping assembly or with rigid, off-the-shelf piping. In either setup, piping for the Liebert
XD system is arranged in a manner similar to piping for a chilled water system. Liebert XD cooling
modules are connected in parallel between main return and supply pipes going to and from the
Liebert XDP/Liebert XDC.
Liebert’s XD System Design Manual, SL-16655, available at Liebert’s Web site: www.liebert.com. The

guidelines provided for pipe size must be strictly followed. Failure to size the main lines
and connection lines adequately may result in reduced cooling capacity. The critical aspects

of pipe sizing are related to refrigerant volume and pressure drop. Each must be minimized.

Figure 19 Liebert XD system diagram

Figure 19 represents a typical configuration. For piping details, refer to

Piping

3.4 Piping Installation Methods

The assembly and connection means used for piping in the Liebert XD system are similar to those
used for conventional refrigeration systems. All piping should be installed with high-temperature
brazed joints. Soft soldering is not recommended.

During brazing, the lines must be filled with flowing dry nitrogen to prevent excessive oxidation and
scale formation inside the piping. Prevailing good refrigeration practices must be employed for piping
supports, leak testing, dehydration and charging. Failure to use good system practices may result in
damage to the system. Refer to the ASHRAE refrigeration handbook for general good-practice
refrigeration piping.

Insulate all piping lines to prevent condensation in applications where the dew point approaches the
R-134a refrigerant temperature.

Emerson recommends venting the pressure relief valve for the R-134a outside the conditioned space
where it is open to the atmosphere. The R-134a side relief valve is inside the Liebert XDP unit at the
top of the receiver.

3.4.1 Piping Installation—R-134a Pumped Circuit

Emerson recommends venting the relief pressure valve of the Liebert XDP (located at the top of the
receiver) outside of the conditioned space where it is open to the atmosphere.

3.4.2 Piping Mains

7/8

"

(22mm) ID

4"(102mm)

All refrigeration piping mains connected to the Liebert XD cooling module, both supply and return,
should be installed with a downward pitch toward the Liebert XDP of 1-2" for every 20 feet
(25.4-51mm per 6m) of pipe run.

Install a 20-40 mesh strainer on the chilled water supply to the Liebert XDP. The strainer is required
to prevent particles in the chilled water from entering the Liebert XDP’s heat exchanger. The
maximum distance from the strainer to the Liebert XDP is 10 feet (3m).

NOTICE

Risk of particles in chilled water. Can cause equipment damage and reduced cooling.
Failure to install a strainer in the supply line to the Liebert XDP can result in damage to the

unit’s heat exchanger.

3.4.3 Bypass Flow Controller

Three bypass flow controllers are required to ensure that the Liebert XDP pumps operate within the
optimum range. These devices are added to the field piping and simulate the flow of additional cooling
modules.

Each bypass flow controller must be installed with one shutoff valve to allow the controller to be
disabled when cooling modules are added to a Liebert XD system.

Bypass flow controllers should be connected between the main supply and the main return lines of the
field piping. The connection points to the main supply and return lines should be in a convenient and
accessible location between the Liebert XDP/Liebert XDC and the first Liebert XD module in the
circuit. See

Figures 20 and 21 for piping details of the bypass flow controller.

Piping

Refer to Table 5 to determine the number of bypass flow controllers that must be open to provide
proper refrigerant flow based on the total nominal cooling capacity of the cooling modules in each
Liebert XD system.

Piping

3.5.1 Evacuation and Leak Check—R-134a Pumped Circuit

1. Open all service valves, including those outside the Liebert XDP.

2. Attach a jumper hose from one of the Schrader valve fittings on a pump outlet before the check
valve to a Schrader valve fittings after the check valve.

3. Place 150psig (1034kPa; 10.34 bars) of dry nitrogen with a tracer of R-134a in the system.

NOTICE

Risk of overpressurization. Can cause equipment damage.
Do not exceed 150 psig (1034 kPa; 10.34 bars) in the R-134a circuit.

4. Check the system for leaks with a suitable leak finder on the pumps’ suctions lines.

5. After completion of the leak testing, release the test pressure (per local code) and connect to
vacuum pump(s) at the Schrader valves.

6. After pulling a deep vacuum for four hours, check the vacuum level and, if it has not changed,

3.5.2 Insulation

break the vacuum with dry nitrogen.

7. Pull a second vacuum to 250 microns or less. Recheck the vacuum level after 2 hours.

NOTE

Do not insulate piping before checking it for leaks. Insulating pipes before checking them for
leaks would prevent easy detection of leaks.

Insulate all piping between the Liebert XDP and its connected cooling modules to prevent
condensation where the piping passes through non-conditioned areas.

22

3.6 Filling the Pumped Circuit—R-134a

Using a refrigerant pump or cylinder heater pads will speed the charging process.

1. Connect a charging manifold to the service port of the receiver outlet valve or to the suction and
discharge side of the pump.

2. Purge the hoses.

3. Calculate the amount of R-134a refrigerant needed to charge the system, using the values in

Tables 6, 7, 8 and 9; for assistance, refer to 3.6.1 - Calculating Refrigerant Charge—
Example. The section includes a worksheet to calculate system refrigerant charge requirements.

4. Weigh in the calculated charge.

5. After adding the calculated charge, allow the system to sit 15 to 30 minutes to reach equilibrium.
Observe the refrigerant level through the sight glasses of the receiver. The level should be above
the second sight glass at a minimum when the Liebert XDP is off.

6. If the refrigerant level is improper, the charge must be adjusted.
If the level is too high or too low, recalculate the required charge and reduce or increase the

amount as needed to reach the proper level.

NOTE

All lengths in Tables 6, 7 and 8 are actual pipe lengths, not equivalent pipe lengths.

NOTE

System refrigerant volume calculations derived from Tables 6, 7, 8 and 9 are based on a fully
loaded system. Additional charge may be required for lightly loaded systems.

Figure 31 Setpoints screen

Liebert iCOM Control—Firmware Version XP1.00.010.STD

Min Room Temperature Setpoint—Sets the minimum room temperature the unit will attempt to
maintain. If the temperature falls below this point, the unit will raise the refrigerant temperature to
reduce the amount of cooling.

The setting is intended to keep the room temperature above the setpoint. Without a proper setpoint,
the Liebert XDP can lower the room temperature too much, depending on the room dew point and
load. This setpoint will reduce the cooling to keep the room temperature above this desired
temperature.

NOTE

This is not a true room temperature setpoint. The Liebert XDP has no heaters; it will try to cool
as much as possible. If the Liebert XDP is able to cool the room to this setpoint, it will reduce its
cooling action to try to keep the room temperature at or above this setpoint.

The default setting is 60°F (15.6°C). The range is 50-80°F (10-27°C).
For optimal cooling performance, the minimum temperature setpoint should be 1-2° below the

expected temperature at the remote sensors, which may affect placement of the remote sensors. If the
minimum temperature setpoint is set above the typical remote temperature sensor reading, it will
reduce the Liebert XD cooling output and, in extreme cases, cause erratic Liebert XD performance.

Spare Parts

Spare Parts—The spare parts lists contains a detailed description and part number that can be used
to order parts for the unit. These part numbers are specific to each model and option installed on the
unit.

Event Log

Event Log—The event log displays all events and actions that have been generated by the unit.
When multiple units are networked you will see the event log of the whole system. Each event shows

temperature is from the Liebert XDP to the modules. The range for the high supply refrigerant
temperature alarm is from 33.8 to 95°F (1 to 35°C); the default is 80°F (26.7°C).

High Chilled Water Temperature—Sets the threshold where a high chilled water temperature
alarm will occur based on the actual reading from the supply chilled water sensor. The range for the
high chilled water temperature is from 33.8 to 95°F (1 to 35°C); the default is 60°F (15.6°C).

4.10 Liebert iCOM Service Menu Screens

Service menus allow customized settings for site operations. Service Menu screens employ a coding
that begins with “S” and is followed by parameters and information, such as settings. Gaining access
to most Service Menus requires entering a password; the Service Menu password is 5010; see
Entering the Password for assistance.

The Liebert iCOM control firmware is being updated constantly. As a result, the Service Menu
parameters in this manual may be slightly different from what is shown on a cooling unit’s display.

4.3.3 -

42

Liebert iCOM Control—Firmware Version XP1.00.010.STD

Min Room Temperature Setpoint—Sets the minimum room temperature the unit will attempt to
maintain. If the temperature falls below this point, unit will raise the refrigerant temperature to
reduce the amount of cooling. Adjustable from 50 to 80°F (10.0 to 26.7°C), the factory default setting
is 60°F (15.6°C).

NOTE

This is not a true room temperature setpoint. The Liebert XDP has no heaters; it will try to cool
as much as possible. If the Liebert XDP is able to cool the room to this setpoint, it will reduce its
cooling action to try to keep the room temperature at or above this setpoint.

Temperature Control Type—Selects the type of control the system will use to activate cooling. The
Liebert iCOM control has three temperature control types: Proportional, PI and Intelligent. The
factory default is Intelligent.

Proportional—If Proportional Control is selected, the percent cooling requirement is
determined by the difference between the air temperature sensor reading and the temperature
setpoint. As the air temperature rises above the temperature setpoint, the percent cooling
required increases proportionally (from 0 to 100%) over half the programmable temperature
proportional band. The percent heating requirement (0 to 100%) is determined the same way
when the air temperature falls below the setpoint.

PI—If PI Control is selected, the percent cooling requirement is calculated by adding together two
individual terms, proportional and integral. The proportional term is calculated in a manner
similar to the previously described Proportional control. The integral term (sometimes called
reset action) is calculated by measuring how much and for how long the air temperature has been
above or below the setpoint. If the actual air temperature is above the setpoint, the percent
requirement is slowly but continuously increased until the total is sufficient to bring the return
room air back to the setpoint.

Intelligent—If Intelligent Control is selected, the air temperature is controlled at or near the
setpoint. The percent temperature adjustment required is calculated based on logic that is
programmed into the control. These rules simulate the actions that would be taken by a human
operator manually controlling the system.

Temperature Proportional Band—Adjusts the activation points of compressors or rate of change
based on the actual sensor values deviation from setpoint. The smaller this number the faster the
compressors and valve(s) will increase capacity. Too small of a number may cause the unit to short
cycle the compressors or excessively reposition the valve. This parameter is adjustable from 1.8 to

54.0°F (1.0 to 30.0°C). The factory default setting is 7.0°F (3.9°C).

Temperature Integration Time—Temperature integration takes into consideration the amount of
time the actual temperature has deviated from the setpoint. The larger this deviation is the longer
the unit will wait before corrective action is taken to achieve the setpoint. This parameter is
adjustable from 0 to 15 minutes. The factory default is 0.

Temperature Derivative Time—Monitors the rate of change and will reduce or increase the
amount of corrective action based on the actual temperature increasing or decreasing toward the
temperature setpoint. This parameter is adjustable from 0-900 seconds. The factory default is 0.

Dewpoint Margin—Selects the difference between the room dew point and the refrigerant
temperature control point. This parameter is adjustable from 4.0 to 10.0°F (2.2 to 6.0°C). The factory
default setting is 4.0°F (2.2°C).

Minimum Control Point—Sets the minimum supply refrigerant temperature the Liebert XDP will
maintain. This parameter is adjustable from 40 to 80°F (4.4 to 27.0°C). The factory default is 55°F
(12.8°C).

Min Percent Cooling Setpoint—Selects the lowest percent call for cooling during normal
operations. Whenever the unit is not in startup mode or OFF, the percent call for cooling cannot go
below this value. The parameter is adjustable from 5 to 30%. The factory default is 15%.

!

5.1 Checklist for Liebert XDP Startup

CAUTION

Risk of piping and component rupture. May cause equipment damage or injury.

Closing service valves may isolate liquid refrigerant, causing high pressure and rupture of
piping. Do not close valves without following recommended procedures for repair,
maintenance and replacement of components. Install pressure relief valves in field piping
that may become isolated by service valves.

NOTE

The Liebert XDP160 requires a minimum load of 48kW (163,800BTU/H) before the system can
be commissioned. This load can be supplied by actual user load in racks, by independent load
banks or by the “Load Bank Testing” service of Emerson Network Power Liebert Services. To
achieve the minimum load requirements, the capacity of all connected modules must total at
least 48kW (163,800BTU/H). See

NOTE

Before any action that could cause a disturbance in the Liebert XD system’s cooling function is
begun, the facility manager MUST be informed. In addition, after the action is taken and the
work is finished, the facility manager MUST be informed

1. Verify that bypass flow controllers were installed (if applicable), see Table 5.

2. Verify that the minimum load level of 48kW (163,800BTU/H) is present.

3. Check all isolation ball valves in the Liebert XDP and Liebert XD cooling module and verify that
all are open.

4. Check rotation of the Liebert XDP’s pumps.
On 460V units only—Hold the rotation device provided against the pump housing at the

inspection screw prior to energizing the pumps. Counterclockwise indicates proper rotation;
clockwise indicates incorrect rotation.

On 208V and 400V units only, view the LED indicator on the pump. Green indicates proper
rotation; Green and Red indicate incorrect rotation.

5.2 Starting the Liebert XDP with Liebert iCOM Controller

Operation above sight glass #3 can
make the system operate erratically
and reduce cooling capacity. Reduce
charge to recommended level.

Recommended operating level

Acceptable operating level

Operation below sight glass #1 may
cause loss of flow or cooling. Add
charge to reach recommended level.

For lightly loaded systems,
the recommended operating
level is sight glass #2.

Sight Glasses 1, 2 & 3

The Liebert XDP is started, stopped and controlled through the Liebert iCOM controller. Figure 24
shows the Liebert iCOM keypad.

1. Turn the Liebert XDP On with the user interface (I/O button). The factory-setting defaults
Liebert XD module fans to On. When the Liebert XDP is turned On, the Liebert XD modules’ fans
will turn On. Allow the system to attempt to start for at least 2 minutes.

If the Liebert XDP pump cannot maintain flow and continues to switch over due to starting
difficulties, refer to

2. If constant flow is established, wait until the Liebert XDP has been operating for 10-15 minutes,
then verify that the refrigerant level in the receiver sight glass is between the second and third
level (see

Figure 71). Add or remove charge, if necessary.

3. Check pressure differential functionality:
The Liebert XDP system should be On. If it is Off:
a. Turn the Liebert XDP On via user interface (I/O button). The factory-setting defaults Liebert

XD module fans to On. When the Liebert XDP is turned On, the Liebert XD modules’ fans will
turn On.

If no “Loss of Flow” alarm is present—This suggests that there is flow. Test the pressure
differential by closing the ball valve on either the suction line or discharge line to stop the
flow.

This should prompt an alarm for “loss of flow on P1.” This alarm confirms that the switch has
opened on low pressure (below 6 psi; 41kPa; 0.41 bars).

If a “Loss of Flow” alarm is present—This suggests that there is no flow. Verify that this
is correctly annunciated by looking at the sight glass in the receiver. If a true no-flow condi
tion exists, the level will not move.

However, if there is flow, but the differential reading is faulty, the level will slowly
drop, indicating flow, while the loss of flow alarm is annunciated.

Check the pressure differential physically by making sure that the electrical connections are
properly connected. Then check the pressure differential electrically by making sure that the
unit has 24VAC across it.

7.0 - Troubleshooting. After remedying the problem, proceed to Step 2.

signal from the supply refrigerant sensor. This alarm will reset when the signal is returned.

UNIT CODE MISSING—Activated when a valid unit code has not been entered and saved. To reset,
enter valid unit code, save and execute.

WATER UNDER FLOOR—Activated when Customer Input 1 is configured for “Water Alarm” and
24VAC is applied to the input. This alarm is reset when the 24VAC is removed.

6.2 Warning Descriptions

LOSS OF POWER—Activated when the unit is On and operational and 24VAC power to the control
is lost. This alarm will be emitted when power is restored to the control. The Liebert XDP will restart
at a user-defined time delay after power is restored. Once activated, the alarm will remain activated
for 30 minutes.

PUMP 1 HRS EXCEED—Activated when the Pump 1 Actual Hours exceeds the user-specified limit.
To reset, Actual Hours must be reset to 0.

Alarm Descriptions and Solutions

PUMP 2 HRS EXCEED—Activated when the Pump 2 Actual Hours exceeds the user-specified limit.
To reset, Actual Hours must be reset to 0.

6.3 System Shutdown Causes

Unit Is Off By Refrig Sens Fail

The control has lost its signal from the refrigerant temperature sensor. The control has no way of
controlling the refrigerant temperature, so the unit is shut off. Main power (disconnect switch) must be
turned Off, then back On to clear this alarm.

Unit Is Off By High CW Temp

The entering chilled water temperature is too high to keep the refrigerant pump(s) running normally. If
a HIGH CW TEMP alarm occurs and the refrigerant pump loses flow (differential pressure), then the
Liebert XDP will go into a pre-chill mode. The Liebert XDP can attempt to start again only if the
entering chilled water temperature drops below the HIGH CW TEMP setpoint.

Unit Is Off By Pump Short Cycle

The control was unable to get a pump started upon startup or after a loss of differential pressure. The
control looks at the SHORT CYCLE time delay. If it cannot establish differential pressure within that
amount of time, the unit is shut down. Main power (disconnect switch) must be turned Off, then back
On to clear this alarm.

Unit Is Off By Low Refrig Temp

The control was unable to raise the refrigerant temperature to the calculated refrigerant temperature
control point. The unit is shut down because if the control cannot raise the refrigerant temperature to
the calculated refrigerant temperature control point, water may condense on the refrigerant piping and
receiving coils. Main power (disconnect switch) must be turned Off, then back On to clear this alarm.

Motor not operating

Check and verify that there is supply chilled water to the
Liebert XDP.

Open all isolation valves completely during normal operation.

Check and verify that the chilled water temperature setpoint is
at 50°F (10°C) or lower and that there is flow on the chilled
water side.

Check Liebert XD cooling modules to make sure that they are
On prior to starting the Liebert XDP.

Check alarm(s) history on Liebert XDP. The Liebert XDP was
operating below the dew point for a significant amount of time.
Check humidity in conditioned space, lower humidity if
necessary to allow Liebert XDP to operate at a lower
temperature. (Disconnect must be switched to Off then back
On to allow Liebert XDP to reset itself).

Check both differential pressure settings. If not within 6 psi, ± 1
psi (41kPa, ±7kPa; 0.41 bars, ±0.07bars) then manually
change accordingly.

Wait at least 10 minutes before calibrating. Access the
Advanced Menu>Factory Settings>Calibrate Actuator.
Contact Liebert Services for assistance, 1-800-543-2778.

Check for adequate charge in system, refer to the User's
Manual. 5.1 - Checklist for Liebert XDP Startup

1. Check humidity of the room along with the location of
remote sensors. Make sure that the sensors are not in a cold
area where there is insufficient air flow for accurate,
representative readings.

2. Chilled Water temperature is too cold.

3. Load is too light.

When power is restored, the Liebert XDP will automatically
restart.

Check the entire system for leaks with a refrigerant sniffer.
Repair as necessary.

Check supply chilled water temperature.

Check wiring.

Call service.

Replace.

Check linkage for adjustment and be sure that it is tight on the
valve.

Unplug P22 from the board. Jumper P22-5 to P52-4 for
grounding, then jumper P22-1 to P52-1 to drive close. Remove
jumper to close and then jumper P22-3 to P52-1 to drive open.
If motor fails to work, replace it.

RH setpoint if necessary to lower dew point. At normal room
temperature of 68°F (20°C), the RH should be set to 50% or
lower.

Check Liebert XD cooling modules to make sure that they are
On before starting the Liebert XDP.

Check the setpoint in the User Setpoints menu (see
Figure 43).

Place the sensor on the return air side of the primary air mover
(eg., Liebert DS). Do not install the sensor near unsealed
doors, windows or similar areas.

8.0 MAINTENANCE

The Liebert XD system components require little maintenance when proper fluid levels are
maintained and proper startup and operation procedures are followed. The following tasks should be
performed at the intervals stated:

1. Clean or replace chilled water strainer annually. Adjust accordingly based on purity of chilled
water.

2. Check sight glass level of receiver every 4-6 weeks. During normal operation, the level should be
at or above the second sight glass.

3. Check system for leaks every 4-6 weeks.

8.1 Fluorinated Greenhouse Gas Requirements

Stationary air conditioning, refrigeration, heat pump equipment and stationary fire protection
systems in the European Community market and operating with fluorinated greenhouse gases (f­gas), such as R407C, R134a, R410A, must comply with the F-Gas Regulation: (EC) No. 842/2006 (F­gas). The regulation prohibits, among other actions, venting fluorinated greenhouse gases to the
atmosphere.

The F-Gas Regulation requires operators to use all measures that are technically feasible and do not
entail disproportionate cost to prevent leakage of these gases, to test for leakage regularly and to
recover f-gas during equipment service and maintenance and before disposing of equipment.

Refer to the full regulation for additional details.
