WARNING!!

• Wear Safety Glasses / Wear Gloves

• Keep the manifold in a dry place. Do not allow moisture to enter the unit.

• Do not vent refrigerant into the atmosphere.

• If eyes come in contact with refrigerant, immediately ﬂush with plenty of water.

Seek medical attention immediately.

• Do not set manifold on top of an A/C system. This will result in incorrect temperature probe

readings.

• STATIC DISCHARGE: Climates in some parts of the world are conducive to creating static

electric build up (ESD). Your digital manifold has been designed to eliminate the damaging

effects of ESD. In some extreme cases, ESD will be apparent on your digital manifold by a

lack of response or an inability to turn off the unit. In the rare case that this occurs, simply

disconnect the battery, wait 1 minute and reconnect the battery. The digital manifold will

“reboot” itself and operate normally once the unit is turned on.

• The display will show zero (0) whenever the measurement falls below the following

readings: 3 PSI, 0.2 Kg/cm, 0.2 BAR, 0.02 mPA or 6 in-Hg

• The digital manifold is normally shipped with vacuum and temperature sensors that are

calibrated with the companion manifold. In the event the other sensors are provided by

another source, please contact Mastercool Inc. for calibration instructions.

BATTERY CARE

When the battery is connected to the unit but not in use it will last six months.

NOTE: In order to prolong the life of the 9V battery;

a.) keep auto-off function enabled

b.) if pressure, temperature or deep vacuum is being used for an extended period of time turn the

unit off and turn back on again when reading is required. (Allow 30-45 seconds for the correct

reading to appear.)

BATTERY INSTALLATION

IMPORTANT NOTES FOR SERVICING AC/R SYSTEM

A system that has been opened or one that is found to be excessively low on refrigerant pressure as a

result of a leak, must be fully evacuated by means of recovery/recycling and deep vacuum. A system

that has been evacuated must be repaired, leak tested and evacuated again before charging.

DIAGNOSING THE SYSTEM PRESSURE AND TEMPERATURE

1. Make sure all valves on the manifold are closed.

2. Connect the blue and red hose from the low and high side of the manifold to the system.

3. Start the system and allow some time for the true pressure reading on the manifold to appear and

stabilize.

CHARGING

1. Verify that all valves on the manifold are shut completely.

2. Turn the A/C system and manifold ON.

3. Connect the other end of the yellow hose to Refrigerant Gas supply.

4. Open refrigerant valve and low side valve slowly and start charging. (Follow refrigerant

manufacturer’s instructions for proper dispensing. Use an electronic scale for accurate charging

(Mastercool #98210-A)

5. When charging is ﬁnished, close the valve on the tank and allow some time for the refrigerant to be

evacuated from the hoses and manifold.

6. Close the low side & refrigerant valve and disconnect the hose(s) from the system.

VACUUM GAUGE OPERATION (SEE FIG.B)

• Press the POWER button to turn the unit ON. Allow 10 seconds for the unit to initialize.

• Close all valves.

• Connect the high side and low side hoses to the system and the yellow or black hose to the vacuum

pump.

• Connect the vacuum cable to the manifold. Connect the other end of the vacuum gauge to the system.

(An additional TEE ﬁtting (Mastercool #99333) or an isolation valve may be required.)

Press the VACUUM button and select the desired unit.

Press ENTER to conﬁrm.

• Start the vacuum pump and open high, low and vacuum valves. The vacuum countdown will start

from atmospheric pressure 00000. Depending on the size of the system, the lines on the LCD

display will disappear one by one. Once all

lines have disappeared, the numerical reading will appear on the LCD. The numbers descend

from 25000 MICRONS or corresponding units.

5www.mastercool.com

NOTE: The unit will shut down after 15 minutes automatically. Press the POWER button again. Allow

30-45 seconds for initializing and the correct vacuum reading to appear. Once the target vacuum is

reached, close the vacuum valve and disconnect the vacuum gauge port from the system. Press the

POWER button to turn the unit off. (If pressure, temperature or deep vacuum is being used for an

extended period of time turn the unit off and turn back on again when reading is required.)

WARNING!! Never stop the vacuum pump unless the vacuum gauge is disconnected.

Failure to do so may cause oil to enter the sensor chamber.

IMPORTANT: When checking a system for leaks under high vacuum (less than 1000 microns),

connect the vacuum gauge directly to the system. If additional connections are required use

copper tubing (do not use rubber hoses) and high vacuum shut-off valves. Standard hoses and

manifold gauge set shut-off valves may have a small amount of leakage under high vacuum.

When initiating a high vacuum test, the vacuum gauge reading may “drift” higher until the sys-

tem has equalized. After this short stabilization period (5 minutes) the vacuum reading should

hold steady. An upward “drift” of the vacuum gauge reading may indicate a leaking system.

MEASURING ACTUAL SUPERHEAT AND SUBCOOLING (SEE FIG. C)

Superheat is the difference between the actual temperature (sensor temperature) of the refrigerant

(gas) as it leaves the evaporator and the boiling point temperature of the refrigerant in the evaporator

coil (saturated temperature). After boiling, the refrigerant continues to warm up. The number of

degrees it “warmed up” after boiling is called the superheat. Under worst-case conditions (low load

for ﬁxed oriﬁce systems), the refrigerant in the evaporator boils off near the end of the evaporator

coil. To make sure liquid doesn’t enter the compressor under the worst case condition, the AC

manufacturers publish charts. The charts indicate what the superheat should be at a given indoor wet

bulb measurement and outdoor air temperature. Measuring superheat is your best indication on a ﬁxed

oriﬁce system of the proper refrigerant charge and operating conditions. If everything else is working

properly and the actual superheat is too high, add refrigerant. If it’s too low, remove refrigerant.

Subcooling is the difference between the boiling point of the refrigerant in the condenser (saturated

temperature) and the actual temperature (sensor temperature) of the refrigerant as it leaves the

condenser. The degrees that the refrigerant “cools down” below the boiling point is the sub-cooling.

Under worst case scenario low load for thermostatic expansion valve systems (TXV) the subcooling will

continue to rise. If the subcooling rises too high, liquid may be backed into the compressor causing

damage and failure.

On TXV systems, the subcooling is the best indication of the state of the charge in the refrigerant system

since these systems are designed to maintain constant superheat. Properly charging a system ensures

maximum efﬁciency and longer equipment life.

Use caution whenever working with electricity and high-pressure liquid or gas.

Always wear safety glasses.

Follow all instructions provided with equipment being serviced or installed.

TARGET SUPERHEAT AND SUBCOOLING

Follow all equipment manufacturer’s speciﬁcations, warnings and suggestions. To determine the target

superheat (ﬁxed oriﬁce system) or subcooling (charts vary dramatically from one system to another),

you will typically need three things. Outdoor dry bulb (outdoor air temperature), indoor wet bulb, and the

manufacturers target superheat chart or subcooling chart.

You can use Mastercool part number 52232 Humidity Temperature Meter for both indoor wet bulb and

outdoor dry bulb. (Refer to diagram.)

6www.mastercool.com

GENERIC TARGET SUPERHEAT & SUBCOOLING CHARTS*

*The required superheat chart is an example of a generic superheat chart of a typical ﬁxed oriﬁce,

split residential system. The required subcooling chart is an example of a typical chart for a TXV, split

residential system. These charts should not be used for charging. They are only examples to show what

the manufacturer’s charts may look like. Follow all manufacturer’s indications, instructions and warnings

above those in this manual.

The indoor wet bulb measurement should be taken as close to the evaporator coil inlet as

possible. The outdoor dry bulb reading should be taken as close to the condenser air inlet as

possible.
