!!!

The SmarTech Digital Manifold is extremely accurate and can be used to pressure test the hoses and manifold valves for leaks. Note: The POE oil used in R410A is very aggressive and causes the rubber seals in the hoses and manifold valve stems to wear rapidly; they may need replacing every couple of months depending on usage. It is recommended to check your manifold and hoses regularly for leaks due to normal wear on rubber gaskets and seats.

1. Connect (C) Blue EZ Turn Hose to manifold 45º hose holder tting.

2. Connect (E) Red EZ Turn Hose to manifold 45º hose holder tting.

3. Connect (D) Black 3/8” Hose with Ball Valve open to nitrogen regulator

using the 3/8”x1/4” adaptor.

4. Open (A) Low Side and (B) High Side manifold valves.

5. Open nitrogen tank valve and set delivery pressure between 400 to 500 psi.

6. Close (D) Black 3/8” Hose Ball Valve. A slight pressure drop is normal as the hoses

stretch under pressure but will stabilize after a couple of minutes.

7. Close (A) Low Side and (B) High Side manifold valves.

8. If digital pressure readings are stable the hoses and manifold are

functioning properly.

9. If the pressure reading continues to decrease there is a leak in the hoses or manifold that must be repaired. Determine origin of the leak and replace the gaskets and O-rings as needed. Repeat pressure test.

Manifold and Hoses Leak Test

Prior to purging the hoses with the refrigerant needed for service it may be necessary to discharge unwanted refrigerant or nitrogen from the hoses.

1. Open (A) Low Side and (B) High Side manifold valves.

2. Aim the (D) Black 3/8” Hose Ball Valve in a safe direction and open

the ball valve to discharge the unwanted refrigerant or nitrogen from the hoses.

3. The digital pressure readings for both Hi and Lo should read zero before continuing to the next step of purging the hoses with refrigerant.

4. Connect (E) Red EZ Turn Hose to (T) Blue Hose EZ Access “T” tting.

5. Connect (C) Blue EZ Turn Hose to refrigerant cylinder.

6. Close (D) Black 3/8” Hose Ball Valve.

7. Open refrigerant cylinder valve.

8. Aim the (D) Black 3/8” Hose Ball Valve in a safe direction, open ball valve and begin purging non-condensable gases.

9. Close (D) Black 3/8” Hose Ball Valve when all non-condensable gases have

been purged.

The SmarTech Digital Manifold is extremely accurate and can be used to pressure test the system for leaks. Prior to pressure testing with nitrogen it may be necessary to discharge unwanted refrigerant from the hoses.

1. Open (A) Low Side and (B) High Side manifold valves.

2. Aim the (D) Black 3/8” Hose Ball Valve in a safe direction and open

the ball valve to discharge the unwanted refrigerant from the hoses.

3. The digital pressure readings for both Hi and Lo should read zero before continuing to the next step.

4. Connect (E) Red EZ Turn Hose to (F) High Side service tting.

5. Connect (C) Blue EZ Turn Hose to (G) Low Side service tting.

6. Connect (D) Black 3/8” Hose with Ball Valve open to nitrogen regulator

using the 3/8”x1/4” adaptor.

7. Open nitrogen tank valve and set delivery pressure to system manufacturer’s recommended test pressure.

8. Close (D) Black 3/8” Hose Ball Valve. A slight pressure drop is normal as the hoses stretch under pressure but will stabilize after a couple of minutes.

9. Close (A) Low Side and (B) High Side manifold valves.

10. If after a few minutes the pressure reading continues to decrease there

is a system leak. The leak must be repaired then repeat the system pressure test.

11. If after a few minutes the digital pressure readings are stable the system is leak-free.

12. Close the nitrogen cylinder valve.

13. Disconnect (D) Black 3/8” Hose from the nitrogen regulator.

14. Open (A) Low Side and (B) High Side manifold valves.

15. Aim the (D) Black 3/8” Hose Ball Valve in a safe direction and open

the ball valve to discharge the nitrogen from the system and hoses.

16. Proceed with evacuating the system.

Prior to charging a system with refrigerant the hoses must be evacuated or purged with the refrigerant needed for service, see Discharge and Purge Hoses before proceeding.

1. Turn system o and connect (E) Red EZ Turn Hose to (F) High Side service tting.

2. Attach (H) Red Temperature Clamp to (F) High Side copper tubing.

3. Connect (C) Blue EZ Turn Hose to (G) Low Side service tting.

4. Attach (J) Blue Temperature Clamp to (G) Low Side copper tubing.

5. Connect (D) Black 3/8” Hose with Ball Valve closed to refrigerant cylinder.

to properly charge the system for maximum eciency and optimal performance.

9. To add refrigerant open (A) Low Side manifold valve.

10. Close (A) Low Side manifold valve and let the system temperatures and pressures

stabilize. Check Superheat and Subcooling “Smart Charge Zone”, if additional refrigerant is needed repeat steps 9 and 10 until the “Smart Charge Zone” is “Green” .

11. Close (A) Low Side manifold valve when desired amount of refrigerant has been added.

12. Close (D) Black 3/8” Hose Ball Valve and refrigerant cylinder valve.

13. Disconnect (D) Black 3/8” Hose with Ball Valve from refrigerant cylinder and

connect to manifold hose holder tting.

14. Disconnect (E) Red EZ Turn Hose and (C) Blue EZ Turn Hose from system and connect to manifold hose holder ttings.

Prior to evacuating the system it may be necessary to discharge unwanted nitrogen or refrigerant from the hoses, see Discharge & Purge Hoses steps 1-2 before proceeding.

1. Connect (E) Red EZ Turn Hose to (F) High Side service tting.

2. Connect (C) Blue EZ Turn Hose to (G) Low Side service tting.

3. Optional: Connect (Uniweld Part# UVG) Digital Vacuum Gauge

to (T) Blue Hose EZ Access “T” tting.
