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. Pos: 28 /TD/Üb erschriften/6. Prod ukt verwend en @ 0\mo d_1173774928554_ 79.docx @ 3 28 @ 1 @ 1

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.

This automatic change occurs when the pressure on the low-pressure side is 1 bar (15 psi) higher than the pressure on the high-pressure side. During the change, Load (2 s) is shown in the display. This mode is especially suited to air conditioning systems which cool and heat (heat pumps).

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
5 Using the manifold 14 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. Key functions > Press [▲] or [▼] to change the reading in the display.
