Handling Procedures
OPERATIONAL INSTRUCTIONS
PRELIMINARY PRECAUTIONS (CONT’D)
Checks for Refrigeration Equipment
When replacing electrical components, ensure they are suitable for the intended purpose and meet the correct
specifications. Always follow the manufacturer’s maintenance and service guidelines. For any uncertainty, consult the
manufacturer’s technical support for assistance.
The following checks must be performed on installations using flammable refrigerants:
Refrigerant Charge Size: Ensure that the charge size is appropriate for the room size where refrigerant-containing
parts are installed.
Ventilation: Verify that ventilation equipment and outlets are functioning properly and are unobstructed.
Indirect Refrigeration Circuit: If using an indirect refrigeration circuit, inspect the secondary circuit to confirm the
absence of refrigerant.
Equipment Markings: Ensure that all markings on the equipment remain visible and legible. Replace any illegible
markings or signs.
Corrosion Prevention: Confirm that refrigeration pipes or components are installed in a location where they are
unlikely to be exposed to substances that could corrode refrigerant-containing parts. If exposure is possible, ensure
the components are made from materials resistant to corrosion or are adequately protected.
Checking for Presence of Refrigerant
• Before and during work, use an appropriate refrigerant detector to check the area for potentially flammable
atmospheres.
• Ensure that the leak detection equipment is suitable for flammable refrigerants (i.e., non-sparking, adequately
sealed, or intrinsically safe).
• Presence of Fire Extinguisher
• If any hot work is required on the refrigeration equipment or related parts, have suitable fire extinguishing
equipment readily available.
• A dry powder or CO2 fire extinguisher should be placed near the charging area.
Checks for Electrical Devices
Repair and maintenance of electrical components must include initial safety checks and thorough inspection
procedures. If a fault is identified that could compromise safety, the electrical supply should not be connected until
the issue is resolved. If the fault cannot be immediately corrected but operation must continue, a suitable temporary
solution may be applied. This should be communicated to the equipment owner to ensure all parties are informed.
Initial safety checks should include:
• Ensuring capacitors are safely discharged to prevent any risk of sparking.
• Verifying that no live electrical components or wiring are exposed while charging, recovering, or purging the
system.
• Confirming continuity of earth bonding.

Handling Procedures
OPERATIONAL INSTRUCTIONS
Repairs to Sealed Components
When repairing sealed components, disconnect all electrical supplies from the equipment before removing any
sealed covers or similar parts. If it is absolutely necessary to have an electrical supply during servicing, a continuously
operating leak detection device should be positioned at the most critical point to provide early warning of a
potentially hazardous situation.
Take particular care to ensure that repairs do not compromise the protective casing of electrical components. This
includes avoiding:
• Damage to cables,
• Excessive or improper connections,
• Use of terminals that don’t meet original specifications,
• Damage to seals, or
• Incorrect fitting of cable glands.
Ensure that all components are securely mounted, and that seals or sealing materials have not degraded to the point
where they no longer prevent the ingress of flammable atmospheres. Replacement parts should be consistent with
the original specifications.
Note: Be aware that using silicone sealant may impair the effectiveness of certain types of leak detection equipment.
Exception: Intrinsically safe components do not need to be isolated before working on them.
Repair of Intrinsically Safe Components
Do not apply any permanent inductive or capacitive loads to the circuit without verifying that they do not exceed
the permissible voltage and current limits for the equipment in use. Intrinsically safe components are the only types
that may be worked on while live in the presence of a flammable atmosphere. Ensure that the test apparatus is
correctly rated for the task.
Replace components only with parts specified by the manufacturer, as using non-specified parts may lead to
ignition of refrigerant from a potential leak.
Cabling
Ensure that cabling is protected from potential wear, corrosion, excessive pressure, vibration, sharp edges, or any
other adverse environmental effects. Consider the impact of aging and constant vibration from components like
compressors or fans when assessing cable durability.
Detection of Flammable Refrigerants
Under no circumstances should potential sources of ignition be used to search for or detect refrigerant leaks. Do not
use a halide torch or any other detector that involves an open flame.

Leak Detection Methods
The following methods are acceptable for detecting leaks in systems containing flammable refrigerants:
Electronic Leak Detectors: Use electronic detectors to identify flammable refrigerants; however, ensure that the
sensitivity is sufficient and recalibrate as necessary. Calibration should be performed in a refrigerant-free area.
Confirm that the detector is not a potential ignition source and is compatible with the refrigerant in use.
Calibration Settings: Set the leak detection equipment to a percentage of the refrigerant’s Lower Flammability
Limit (LFL) and calibrate it to the specific refrigerant being used. Verify that the gas concentration does not exceed
25% of the LFL.
Leak Detection Fluids: Most refrigerants are compatible with leak detection fluids, but avoid detergents containing
chlorine, as chlorine can react with the refrigerant and corrode copper piping.
Safety Precautions: If a leak is suspected, extinguish all open flames in the area.
Brazing Leaks: If a refrigerant leak requiring brazing is detected, recover all refrigerant from the system or isolate it
in a section of the system away from the leak using shut-off valves. Purge the system with oxygen-free nitrogen
(OFN) before and during the brazing process.
Removal and Evacuation
When accessing the refrigerant circuit for repairs or other purposes, use conventional procedures, but adhere to best
practices due to flammability considerations. The following steps should be followed:
Remove the Refrigerant: Recover the refrigerant into appropriate recovery cylinders.
Purge with Inert Gas: Purge the circuit with an inert gas such as oxygen-free nitrogen (OFN).
Evacuate the System: Evacuate the system to remove any remaining gases.
Purge Again: Perform a second purge with inert gas.
Open the Circuit: Open the circuit by cutting or brazing as needed.
The system should be “flushed” with OFN to ensure it is safe. This flushing process may need to be repeated several
times. Do not use compressed air or oxygen for this purpose.
To flush the system, break the vacuum with OFN until the working pressure is reached, vent to the atmosphere,
then pull down to a vacuum. Repeat this process until no refrigerant remains in the system. When applying the final
OFN charge, vent the system down to atmospheric pressure to allow for safe work, especially if brazing operations
are required on the pipework.
Ensure the outlet of the vacuum pump is kept away from any ignition sources and that the area is well-ventilated.

MAINTENANCE, SERVICING, & REPAIRS (CONT’D)
Charging Procedures
In addition to standard charging procedures, observe the following requirements:
Prevent Contamination: Take care to prevent cross-contamination of different refrigerants when using charging
equipment. Hoses or lines should be kept as short as possible to minimize the refrigerant volume they contain.
Cylinder Position: Always keep cylinders upright.
Earthing: Ensure the refrigeration system is properly grounded before charging it with refrigerant.
Labeling: Label the system once charging is complete, if it hasn’t already been labeled.
Avoid Overfilling: Take extreme care not to overfill the refrigeration system.
Before recharging, perform a pressure test on the system with oxygen-free nitrogen (OFN). After charging, but
before commissioning, conduct a leak test. A follow-up leak test should be performed before leaving the site.
Decommissioning
Before starting the decommissioning process, the technician must be thoroughly familiar with the equipment and all
its details. It is recommended to safely recover all refrigerants. Prior to beginning the task, collect an oil and
refrigerant sample in case analysis is needed before reusing reclaimed refrigerant. Ensure that electrical power is
available before starting.
Preparation:
• Review equipment and its operation to ensure familiarity.
• Electrically isolate the system.
Verify the following before beginning:
• Mechanical Handling: Mechanical handling equipment is available if needed for refrigerant cylinders.
• Personal Protective Equipment (PPE): All necessary PPE is available and used correctly.
• Supervision: The recovery process is monitored at all times by a qualified person.
• Standards Compliance: Ensure recovery equipment and cylinders meet appropriate standards.
Recovery Process:
• Pump down the refrigerant system, if possible.
• If a vacuum cannot be achieved, set up a manifold to remove refrigerant from different parts of the system.
Place the recovery cylinder on a scale before starting recovery.
Operation:
• Start the recovery machine and follow the manufacturer's instructions.
• Avoid overfilling cylinders; limit the liquid charge to no more than 80% of the cylinder’s volume.
• Do not exceed the cylinder's maximum working pressure, even temporarily.

Handling Procedures
OPERATIONAL INSTRUCTIONS
MAINTENANCE, SERVICING, & REPAIRS (CONT’D)
Completion:
• Once cylinders are filled correctly and the recovery process is complete, remove the cylinders and equipment from
the site promptly.
• Close all isolation valves on the equipment.
• Recovered refrigerant must not be charged into another refrigeration system unless it has been properly cleaned
and inspected.
Recovery
When removing refrigerant from a system for servicing or decommissioning, it is best practice to ensure that all
refrigerants are safely removed. When transferring refrigerant to cylinders, only use appropriate refrigerant recovery
cylinders. Ensure that the correct number of cylinders is available to hold the total system charge. All cylinders used
must be designated and clearly labeled for the specific refrigerant being recovered. They should also be equipped
with pressure relief valves and functional shut-off valves. Empty recovery cylinders should be evacuated and, if
possible, cooled prior to use.
The recovery equipment must be in good working condition, suitable for use with flammable refrigerants, and
accompanied by operating instructions. Additionally, calibrated weighing scales should be available and in proper
working order. All hoses should have leak-free disconnect couplings and be in good condition. Before using the
recovery machine, verify that it is in proper working condition, well-maintained, and that all electrical components
are sealed to prevent ignition in the event of a refrigerant leak. Consult the manufacturer if there is any doubt.
Recovered refrigerant should be returned to the refrigerant supplier using the appropriate recovery cylinder, and a
relevant Waste Transfer Note must be arranged. Do not mix refrigerants in recovery units or cylinders.
If compressors or compressor oils need to be removed, ensure they are evacuated to a safe level to prevent residual
flammable refrigerant from remaining in the lubricant. This evacuation must be done before returning the
compressor to the supplier. To speed up the process, only use electric heating to warm the compressor body. Oil
drained from the system must be handled safely.
INSTALLATION ENVIRONMENT OF THE AIR CONDITIONER
The air conditioner can be installed either during the production phase of the RV or after its completion. It must be
installed horizontally on the top of the RV.
• The minimum spacing between rafters and joists on the roof structure should be 15-3/4 inches.
• The roof thickness of the RV must be at least 1 inch and no more than 4 inches.
• If the roof thickness exceeds 4 inches, an additional air duct connection is required.
Intended Purpose of the Air Conditioner
This air conditioner is designed specifically for RVs to enhance internal temperature control and create a
comfortable environment. It provides cooling during hot weather and heating during cold weather, along with
adjustable temperature settings for both conditions.

Usage Information
OPERATIONAL INSTRUCTIONS
9
OPERATIONAL CHARACTERISTICS
The performance of the air conditioner is influenced by the insulation properties of the RV itself. Users can take
preventive measures to minimize heat entry, thereby enhancing the cooling efficiency of the air conditioning system.
When the outdoor temperature is high, consider the following steps to reduce heat penetration into the RV and
improve system performance:
• Park the RV in a shaded or cool area.
• Enhance the thermal insulation of the compartment, block openings in the vehicle, and use shade curtains,
shutters, or hanging curtains over windows.
• Keep doors and windows closed and limit their opening and closing as much as possible.
• Avoid using heat-generating devices inside the vehicle.
• Turn on the air conditioner in advance for optimal cooling performance.
When indoor or outdoor temperatures are high, setting the air conditioner to cooling mode and using the high fan
speed setting can maximize its performance.
Note: Due to significant changes in air temperature within the vehicle, rapid cooling may cause some condensation to form
on surfaces near the air outlet. This is a normal occurrence. As the air conditioner operates for a longer period, the
condensate will typically dry out and detach from surfaces. To reduce condensation, keep doors and windows closed as much
as possible while the air conditioner is in use. The manufacturer is not liable for any damage resulting from condensation
on the ceiling or other surfaces due to the air conditioner’s operation.
Note:
• Please use connecting wires that comply with national regulations.
• When selecting a generator, consider the total power consumption of the RV.
• Generators may experience power loss at high altitudes or due to insufficient maintenance.
• Circuit Protection: Always use a leakage circuit breaker for safety.

walls and roof.
• Geographical Location: e climate and conditions of the location where the RV is used can impact cooling
requirements.
Factors for Installation
is product is intended to be installed on an existing roof
vent. Typically, a 14-1/4" x 14-1/4" ± 1/8" opening will be
available on the roof after the vent is removed.
If there is no vent on the roof, or if this product needs to be
installed in another position, it is recommended to follow
these guidelines:
1. When installing a single air conditioner, it should be
positioned slightly ahead of the center point (as viewed
from the front of the vehicle) and centered between the left
and right sides, as shown in the following gure.
2. When installing two air conditioners, they should be
positioned at the 1/3 and 2/3 points from the front end
