> If the manifold falls or another comparable mechanical load
occurs, the pipe sections of the refrigerant hoses may break.
The valve stem shutoff may also be damaged, whereby further
damage to the interior of the manifold may occur that cannot be
identified from the outside. The refrigerant hoses must therefore
be replaced with new, undamaged refrigerant hoses every time
the manifold falls or following any other comparable mechanical
load. Send the manifold to Testo Customer Service for a
technical check for your own safety.

Testo 549 and testo 550 are digital manifolds for maintenance and
service work on refrigeration systems and heat pumps. They are
intended for use by qualified personnel only.
The functions of the testo 549 and testo 550 are designed to
replace analog manifolds, thermometers and pressure/temperature
charts. Pressures and temperatures can be applied, adapted,
tested and monitored.
Testo 549 and testo 550 are compatible with most non-corrosive
refrigerants, water and glycol. Testo 549 and testo 550 are not
compatible with refrigerants containing ammonia.
The instruments must not be used in explosive environments!

Operating the valve stem shutoffs
The digital manifold acts like a conventional two-way manifold with
regard to the refrigerant path: The passages are opened by
opening the valves. The adjacent pressure is measured with valves
closed as well as with them open.
> Open valve: Turn valve positioner counterclockwise.
> Close valve: Turn valve positioner clockwise.
WARNING
Over tightening the valve stem shutoffs may cause:
• Damage to the PTFE seal.
• Mechanical deformation of the valve piston leading to the
PTFE seal falling out.
• Damage to the thread of the threaded spindle and the valve
screw.
• valve knobs to brake.
Lightly tighten the valve knob. Do not use tools to tighten the valve
stem shutoffs.

5.1.
Preparing for measurement
5.1.1.
Switching the instrument on
> Press [
].
Zero the pressure sensors before every measurement.
✓ All connections must be at ambient pressure.
> Press [P=0] key for 3 seconds to execute zeroing.
Connecting the refrigerant hoses
Before each measurement check whether the refrigerant
hoses are in flawless condition.
✓ Make sure the valve stem shutoffs are closed.
1. Connect the refrigerant hoses to the low-pressure side (blue)
and high-pressure side (red).
2. Connect the refrigerant hoses to the AC/R system.
WARNING
Dropping this instrument or any other comparable mechanical
shock can damage the refrigerant pipes and hoses. The valve
actuators may also suffer damage, which in turn could result in
further damage inside the instrument and may not be
detectable from outside.
> For your own safety you should return the manifold to the
Testo Service Department for technical inspection.
> You should therefore always replace the refrigerant hoses with
new ones after an accidental drop has occurred or after any
visible wear and tear.
Choosing the refrigerant

Connecting the temperature sensor
Surface temperature sensor
At least one NTC temperature probe must be connected to
measure the pipe temperature, for automatic calculation of
superheating and subcooling.
Deactivating the surface compensation factor for insertion and
air temperature sensor
A surface compensation factor has been set in the measuring
instrument to improve the measuring accuracy of surface
temperature readings.
If the manifold is used in combination with insertion or air
temperature probe (optional), this factor must be deactivated:
1. Press [Set] repeatedly until Tfac is displayed.
2. Press [▲] or [▼] to set Tfac to Off.
3. Press [Set] to continue through the settings menu until the
measurement/home view is displayed.
- Tfac is shown on the display if Tfac is disabled.

Performing the measurement
WARNING
Risk of injury caused by refrigerant that is at high pressure,
hot, cold, or poisonous!
> Wear safety goggles and protective gloves..
> Before pressurizing the measuring instrument: Always fasten
the measuring instrument at the hanging hook in order to
prevent it from falling (risk of breakage)
> Check if the refrigerant hoses are intact and connected
correctly before each measurement. Do not use a tool to
connect the hoses. Only tighten the hoses by hand (max.
torque 5.0 Nm/3.7 ft*lb).
> Do not exceed the permissible measuring range (0 to 870 psi /
0 to 60 bar). Pay particular attention with systems with
refrigerant R744, as these are often operated with higher
pressures.
Measuring
1. Connect and apply pressure to the manifold.
2. See readings.
Note: With refrigerants that have a temperature glide,
“Zeotropes” the evaporation temperature Ev/to and
13
5 Using the manifold
condensation temperature Co/tc are displayed after
evaporation and condensation are complete.
Zeotropes (refrigerants blends mix together) can separate
from each other, unlike azeotropes which mix together to
become one. Zeoptropes often blend refrigerants with
different boiling points (saturation temps), where one will
change from liquid to vapor before the other as they go
through the evaporator. The glide is the difference between
the lowest boiling point and the highest boiling point. If they
are 3 degrees apart, for example, the blend has a 3 degree
glide..
The display illumination will flash if:
• The critical pressure of the refrigerant is within 15 psi (1 bar)
of the highest pressure (and temperature) where the
refrigerant can still condense.
• The maximum. permissible pressure of 870 psi (60 bar) is
exceeded.

Leak test / pressure drop test
Systems can be tested for tightness with the temperaturecompensated leak test. The system pressure and the
ambient temperature are measured over a defined period of
time, typically with an inert gas such as Nitrogen. A
temperature probe can be connected that measures the
ambient temperature. : Optional air temperature probe,
part. no. 0613 1712) is recommended.
Measurement data of the temperature-compensated
differential pressure and temperature, from start to the end
of the test, is displayed. It is possible to perform a leak test
without connecting a temperature probe.
1. Press [Mode] ΔP is displayed.
2. Start the leak test: Press [R, ►, ■]. ΔP is now flashing and

2. Start the vacuum pump.
- Once the measuring range 0 to 20,000 microns is reached, the
current vacuum value is shown on the instrument display. The
instrument also displays the current ambient temperature, the
water evaporation temperature, which corresponds to the
vacuum reading, and the delta between these two
temperatures.

Keeping connections clean
> Keep screw connections clean and free of grease and other
deposits, clean with a moist cloth as required.
Removing oil residues
> Carefully blow out oil residues in valve block using compressed
air.
To ensure measuring accuracy
> Check instrument regularly for leaks (recommended: annually).
Keep to the permissible pressure range!
> Calibrate instrument regularly (recommended: annually).
Changing batteries/rechargeable batteries
✓ Instrument is switched off.
1. Fold out the hook, loosen the clip and remove the cover of the
battery compartment.

7 Maintaining the product
2. Remove discharged batteries/rechargeable batteries and insert
new batteries/rechargeable batteries (4x 1.5 V, type AA,
Mignon, LR6) in the battery compartment. Observe the polarity!
3. Set on and close cover of the battery compartment (clip must
engage).
4. Switch the instrument on.
Changing the valve or valve stem shutoff
DO NOT ATTEMPT to change the valve stems. Changing the valve
stem shutoff or valves themselves will void the warranty.
Send the measuring instrument to Testo Customer Service.
Cleaning the vacuum probe
Contaminants such as oil may impair the accuracy of the vacuum
sensor.
CAUTION
Carrying out cleaning with the probe connected may result in
damage to the probe!
> Remove the vacuum probe from the testo 557!
CAUTION
Damage to the sensor due to sharp objects!
> Do not insert any sharp objects into the probe!
1. Remove the vacuum probe from the testo 557.
2. Put a few drops of rubbing alcohol into the sensor opening.
3. Seal the opening by placing your finger on it and shake the
vacuum probe briefly.
4. Remove all the alcohol from the probe.
5. Repeat this process at least twice.
6. Leave the probe to dry for at least 1 hour. To dry the sensor
faster, you can connect the probe directly to a vacuum pump
and draw vacuum.
