Rechargeable Factory Direct Professional Grade Refrigerant And Blend Leak Detector (Johnson Controls

Rechargeable Factory Direct Professional Grade Refrigerant And Blend Leak Detector (Johnson Controls)

Overview
This is a professional grade leak detector for use by refrigeration
and air conditioning technicians. This detector senses all CFC, HCFC,
and HFC refrigerants and blends, such as R12, R502, R22, R404a, R507
and R134a, among others. This is self-powered with a rechargeable
battery and provides both manual and automatic compensation for
background levels of refrigerant. A full line of accessories and
maintenance kits are also available, including replacement sensors,
tune-up kits, probe extensions, battery chargers, and leak vial bottles.

Features and Benefits
• Positive Ion Emission Heated Diode Sensor: Provides the most sensitivity available today, while still detecting all halogenated refrigerant gases
• Rechargeable Battery Enhances portability--no external power required
• High Quality Air Pump Supplies constant air flow to sensor so it responds quickly to leaks; also helps sensor recover quickly after exposure to refrigerant so leak can be verified
• Auto Balance Circuit Compensates for background refrigerant levels
• Visual and Audible Signal Facilitates sensing in noisy equipment rooms with 360° visibility and piercing tone; Frequency of noise/light indicates magnitude of leak
• Exceeds SAE J1627 Moving Probe Specification Minimizes call-backs because the leak is found the first time, is verifiable, and the fix can be confirmed
• External Calibration Source Indicates when the sensor is working properly and serves as a reference point to judge leak size

Application Overview
Growing concern over the effects of certain
refrigerants on the atmosphere has generated a strong
motive to eliminate system leaks and to develop safer
refrigerants. With the RLD-H10P, you can be
confident that your instrument will provide the
sensitivity and capabilities to meet your service needs
today and for the years to come.
The RLD-H10P is intended principally as a service
technician’s tool. This detector has the capability to
detect small amounts of halogenated gases, including
chlorine and fluorine based refrigerants and blends.

Theory of Operation
The leak detector consists of a control unit with an
auto balancing circuit, a probe with a 4.5 ft cable, a
rechargeable battery, and a battery charger housed in
a shock resistant molded polyethylene case. The
sensor uses positive ion emission technology, which is
based on the ionization characteristics of alkali metals.
The alkali metals act as the cathode of a diode, and
the anode is heated by a DC voltage. Air from the
area being leak checked is pumped from the probe
and into the space between the cathode and anode. If
halogen gas is present, it creates an ionized current
between the cathode and the anode, which is amplified
to sound a speaker and light a neon lamp in the probe.
Sensitivity can be controlled by adjusting the current
(temperature) through the sensor.

Calibration and Verification
The leak vial may be used as often as necessary to
assure proper operation of the RLD-H10P, and to
assist in determining the size of the leak. When using
the small leak range position, a leak of HFC causing
an audible signal equal to that produced by the
leak vial has a leak rate of approximately
one-half ounce/year. When using the medium leak
range position on a CFC or HCFC system, this leak
rate would also be approximately one-half ounce/year.
Proper response during the calibration test verifies
sensitivity and operation for all three test positions.
1. Ensure that the range switch is in the small (“SM”)
position.
2. Remove the black, sticky-label disc from the cap of
the leak vial and discard. Allow a few minutes for
the leak rate to stabilize. Do not attempt to
unscrew the cap, as you may damage the bottle.
It is filled with enough refrigerant to last
approximately six months.
3. Test operation by briefly moving the probe tip over
the opening of the leak vial as if you are trying to
locate this leak. It is not necessary to hold the
probe over the leak, as this does not simulate field
conditions.
The RLD-H10P should respond with an increase in
flash rate and sound, verifying operation and
indicating the location of the leak.
4. If the RLD-H10P does not respond to the leak vial,
make sure there is liquid in the bottle. If the unit
still does not respond to the leak, increase the
sensor heat slightly by turning the sensor heat
control knob 1/16th of a turn clockwise.
5. Allow a minute for the sensor to heat, then repeat
the calibration procedure.

Charging the Batteries
The RLD-H10P will run continuously for approximately
1.5 hours on a fully charged battery. When the battery
light is lit, the unit should be recharged.
IMPORTANT: The RLD-H10P contains a gel-cell
battery. To prolong the life of this
type of battery: recharge the battery
frequently (before it is fully
discharged); do not recharge the
battery for more than eight
consecutive hours. Do not allow the
battery to freeze.
