5. સ્થાપન અને સેટઅપ
5.1 Orifice Selection
The nominal capacity of the TS2 valve is determined by the orifice size, which is sold separately. To select the correct orifice, use one of the following methods:
- System Characteristics: Select the orifice using appropriate refrigerant, evaporator temperature, and system capacity requirements.
- Nominal Capacity of Installed Valve: Match the nominal capacity of the originally installed valve with the capacity chart provided. If an exact match is not found, use the next larger orifice size.

5.2 કનેક્શન
The valve body features flare inlet and outlet connections. Ensure proper sealing and torque when connecting to refrigeration lines. Flare/solder adapters are available as optional accessories if needed for your system.
6. Operation and Adjustment
6.1 Superheat Adjustment
The superheat setting can be adjusted to optimize system performance. Make adjustments in small increments to avoid over-correction:
- Adjust superheat 1/4 turn at a time. Each 1/4 turn typically equals approximately 1.75°F (1°C) change in superheat.
- Turning the adjustment screw clockwise increases superheat.
- Turning the adjustment screw counter-clockwise decreases superheat.
Allow the system to stabilize after each adjustment before making further changes.

7. જાળવણી
The Danfoss TS2 Expansion Valve is designed for long-term reliability. Key maintenance considerations include:
- ઓરિફિસ એસેમ્બલી: The valve features a replaceable orifice assembly with a dirt-protection filter. Regular inspection and replacement of the orifice and filter, as needed, can help maintain optimal performance and prevent system contamination.
- લીક તપાસ: Periodically check all connections for refrigerant leaks using appropriate leak detection methods.
- સિસ્ટમ સ્વચ્છતા: Ensure the refrigeration system remains clean and free of contaminants to prevent blockages and damage to the valve.
8. મુશ્કેલીનિવારણ
If the refrigeration system is not performing as expected, consider the following general troubleshooting steps:
- Incorrect Superheat: Verify and adjust the superheat setting as described in Section 6.1.
- Orifice Blockage: A clogged orifice or filter can restrict refrigerant flow. Inspect and clean or replace the orifice assembly if necessary.
- રેફ્રિજન્ટ ચાર્જ: Ensure the system has the correct refrigerant charge. Both undercharge and overcharge can affect valve performance.
- External Equalization Line (if applicable): For valves with external equalization, ensure the equalization line is properly connected and free of obstructions. (Note: This specific model has internal equalization).
- Sensing Bulb Placement: Ensure the sensing bulb is securely attached to the suction line in the correct position and insulated properly.
For complex issues, consult a qualified HVAC/R technician.
