CERTIFIED REFRIGERANT TEST GAS MIXTURES

Some municipalities require the use of a certified test gas to validate the installation

prior to approving the Building Inspection. YELLOW JACKET does not offer certified

test gases but has identified the following source which can ship the gas via UPS. They are small high pressure cylinders which require a special regulator. The test

gases are mixed with dry nitrogen or air depending on the gas under test and are

shipped via UPS ground. MSA Mine Safety Appliances

TIP: A YELLOW JACKET quick coupler gasket (#19020) inserted in the end

of the syringe will help make a seal at the cylinder port. Open the cylinder

valve until a light hiss can be heard. This will purge air from the cylinder port.

Press the syringe against the cylinder port and watch the plunger move as the

syringe fills. Close the cylinder valve when the syringe is full.

MAKING AND USING A REFRIGERANT TEST GAS MIXTURE

Materials:

Procedure: NOTE: Perform these steps in an area away from the refrigerant monitor. 1. Clean the plastic jug by blowing it out with compressed air. Start with the syringe

plunger fully engaged (0cc). Carefully fill the syringe with vapor refrigerant from

the virgin cylinder. This should be done in an area away from the plastic jug.

to obtain the desired volume (4cc for a ~1000ppm mixture, 2cc for a ~500ppm

2. Immediately turn the syringe so the opening is upward. Slowly move the plunger

mixture). If the plunger moves below the desired volume, go back to step 2.

opening of the syringe to contain the measured gas. Place the opening of the

3. Once the proper volume is achieved in the syringe, place your finger over the

syringe into the opening of the plastic jug, remove your finger, and slowly release

the refrigerant sample down into the jug by pressing on the plunger.

4. When the syringe plunger is fully engaged, remove the syringe from the jug, place

the screw cap on the jug, and tighten the screw cap so it seals. Allow the jug to sit

in an upright position for a few minutes. Then turn the jug upside down and allow it

to sit for a few more minutes in this position. This will allow the refrigerant to blend

with the air in the jug.

A NOTE ON TESTING

To test refrigerant monitors, open the jug screw cap and place the opening of the jug

over the sensor, holding it so it seals against the sensor housing. This will minimize the

dissipation of the sample. Once the test is completed, immediately replace the screw

cap. Avoid rapid movement of the jug when it is open, as this will create air currents

that will dissipate the sample. Mix a fresh sample as required.

INSTALLATION INSTRUCTIONS

The controller and its sensors should be positioned carefully to avoid mechanical

damage, i.e. moving product, machinery, doors, etc.. They should also be kept away

from heat sources and should not be placed in strong drafts or in high moisture areas. DO NOT route sensor cables on building exteriors or between buildings via overhead

cables. Also, sensor wiring should be kept a minimum of 1.5 feet (500mm) from

electrical and telephone cables. (See section on sensor location). The controller and sensor must be installed in accordance with these instructions to

protect this equipment and ensure its correct performance.

QUANTITY AND LOCATION OF SENSORS

Sensor cable length must not exceed recommendations for the type of monitor if the

unit is to operate correctly. For one and two sensor models the wires to the sensors

cannot exceed 200 feet (60 meters). For four and six sensor models the sensor wires

cannot exceed 500 feet (160 meters). It is sometimes difficult to determine the number of sensors needed and the best

location of the sensors, as there is no hard and fast rule. However, there are a number

of simple guidelines which help to make the decision easier. Most standards normally

recommend some degree of ‘overkill’ to ensure adequate coverage. The two methods of locating sensors are “Point”, where sensors are located near the

most likely sources of leakage, and “Perimeter”, where sensors completely surround

the hazardous area. The size and nature of the site will help to decide which of these

methods is the most appropriate to use, consider the following:

YELLOW JACKET sensors can be calibrated for a maximum sensitivity to either group

“A” or group “C” refrigerant gases. If not specified ,the default is to Group A gases. Important: Do not try to economize by using the minimum number of sensors

possible. A few extra sensors could make all the difference when a gas leak occurs!

POSITIONING SENSORS

When detecting a refrigerant gas with vapor density greater than 1 (i.e. heavier than

air) the sensors should be located near ground level, approximately 16 –20” (40-50cm)

from the floor. Examples of such gases would be butane, LP Gas, xylene and very cold

ammonia in a deeply refrigerated cold storage. For any lighter than air gases, such as ammonia, methane or hydrogen, the sensor

needs to be located higher, 8-12” (20-30cm) from top of wall.
