How To Add Freon To Camper Ac Unit

How to put freon in rv rooftop air conditioner

RVs are the ultimate choice for those who honey to get on vacations. With an RV, you can basically have your domicile with you lot even if yous are abroad from home. Of course, your trips will never exist comfy without your RV's Air-conditioning. This is why learning how to put Freon in an RV rooftop air conditioner will help you enjoy the full benefits of the unit of measurement during your travels.

Steps for putting freon in your RV rooftop Air-conditioning

The AC works by passing air over the evaporator coil that is cooled using a refrigerant. Freon is the most common and popular refrigerant. This make proper name is really under the ownership of DuPont and is universal although incorrectly used ass a generic term.

Lower refrigerant levels will pb to reduced efficiency of the machine. Rooftop units don't often come with user-serviceable ports since most of the time, the systems are already sealed right at the manufactory. In order to put in Freon, an expert must weld a charging port to the system.

Below are the steps you demand to follow for putting in Freon in the rooftop Air-conditioning of your RV.

Elevator and release the outer shroud of the rooftop AC. A serial of fasteners surrounding the lower rim holds this shroud in place. Utilise a socket, wrench, or screwdriver depending on the specific fasteners that the manufacturer used. Be sure that you don't become into contact with the fragile equipment within as you lift the example away.
Cheque the machinery to determine if a refrigerant port is present. If ever there is one, you can notice this on the side of the car containing the bigger of the ii copper tubes running from the compressor to the interior of the RV and its evaporator curl. It is referred to equally the arrangement's suction side.
Consult the machine'southward data tag or manufacturer's literature to know the specific blazon of required refrigerant. Older vehicles oft employ R22 that has at present become difficult and expensive to source. The newer vehicle models use another types. Be sure to get a recharge kit of the suitable refrigerant.
Utilise the thermostat for measuring the ambience temperature in the RV's interior. Look for the Ac'due south chart that is often fixed inside the shroud. This chart indicates a series of temperatures that are noted together with a series of the ideal refrigerant pressures, with ane for every specific temperature.
Connect the manifold gauge hose visibly labeled to exist for the port's suction side, often the left-hand hose. Screw the female person hose stop to attach information technology in clockwise direction to the port'due south male threads.
Switch on the AC to activate information technology through going for the thermostat's coldest setting.
Bank check the approximate clearly indicated to be for the suction side to verify the need for a recharge or summit-up. Read the force per unit area of the refrigerant within the Air conditioning and compare it to the ambient temperature effigy in the chart that matches the reading from the RV's interior. If the pressure of the refrigerant is lower than optimum for the measured temperature inside the RV, a recharge or top up of the organization is necessary.
Adhere the recommended refrigerant's container to the hose visibly labeled to be for this specific purpose that is frequently the central hose. The gauges can be purged through a cursory opening and closing of the valve visibly labeled for that purpose, typically the right paw valve.

This clearly labeled charge valve should be opened to allow the Freon get inside the Air-conditioning for a minute. Be sure to shut the valve and so wait for another infinitesimal earlier you lot recheck the gauge. You lot tin exercise this process again as needed until you reach the refrigerant pressure level level indicated as optimum for the measured temperature inside the RV.

Do RV air conditioners need freon?

Every ac unit uses a dissimilar type of coolant to reduce the air temperature. It is important to bank check the owner's manual to know the exact specifications of the coolant beingness used by your RV's Ac unit earlier you lot buy Freon.

Still, there are instances when RV ACs are meant to be a single-use system. It means that most of the time, these don't come up with ports too every bit other attachments required for recharging them with coolant.

When recharging your RV in many instances, at that place is a demand to install valves. The RV air conditioner is often hermetically sealed. Information technology ways that the seal must be broken to recharge it. This tin be a bit expensive and the unit may demand to exist replaced if the technician has no thought about how to do it.

Dissimilar types of freon for RV air conditioners

Almost RVs take sealed air-conditioning units. It indicates that the coolant within is meant to last for as long every bit the aircon lifespan. Information technology is not the example all the fourth dimension since things tin can happen and some leaks may class.

If you need to supplant or add together Freon in the Air-conditioning unit of measurement of your RV, Freon R22 should be used. Thankfully, it is a mutual Freon although there are stringent regulations when it comes to handling it. You will need one of the iii licenses to handle and buy R22 coolant.

2 other Freon types used in RVs include R-410A and R-134a. How often to top up aircon gas?

Other pointers to remember when putting freon in an RV rooftop air conditioner

Yous accept to be extra careful when you put Freon in the air-conditioning unit of your RV. This is non the kind of task for people who don't really have the patience too every bit those who are not that careful with the work they exercise. Being extra careful is necessary since there are lots of frail parts and equipment found inside.

If you are not confident with your mechanical skills, information technology is not advisable that you effort to do this task on your own. Exist sure to take your RV to a professional mechanic with the noesis and feel in doing a practiced task.
