Atricle Dump - Heater And Air Conditioning System Precautions
There is a great misconception about telemarketing. Say that word and people conjure images of having their day interrupted by machine-like individuals only interested in making a sale. This image is why so many have refused to list their number or have even gone as far to put themselves on a 'no-call' sheet. Is this wrong?Yes and no.There are, of course, going to be times when you do not want to chat with a persistent telemarketer. Everyone has received that long call during dinner, after having to deal with hard hours at work. When you want to relax, listening to a sales pitch is not the idea that comes to mind. So, yes, you give an abrupt goodbye or just forgo that formality all-together and hang up.But... is this right? Should you simply refuse to listen to a telemarketer? Many would give a resounding "Yes!". That is too hasty an answer, however. Sometimes, you have to listen to what is being offered--it may just be something you need.Telemarketing, as an idea, works. It is the execution that people object to. That does not change the fact, however, that products and services (that you may need) are being offered. Yes, talking on the phone can be a hassle and, yes, you are not going to always be up for it. This should not force you into a phone-seclusion, though. Telemarketing could be a way for you to discover products that you would have otherwise
PLACING SYSTEM IN OPERATION
1. Evacuate the system using a vacuum pump.
2. Charge the system with new R-12 according to each individual vehicle to Refrigerant Capacity.
3. Leak test the system, with particular attention to all new connections and components.
4. Make a performance test of the system.
COMPRESSOR REMOVAL INFORMATION
On systems which have compressors equipped with stem-type service valves, it is possible to isolate the compressor for removal.
Turn both high and low pressure manual valves to extreme clockwise position. Loosen cap on high pressure manual valve connection to compressor and allow gas to escape until compressor is relieved of pressure.
COMPRESSOR REMOVAL INFORMATION - DISCHARGE METHOD
This procedure is to be used on vehicles which have compressor equipped with Schrader valves. In these cases, the compressor cannot be isolated and the system must be discharged, using approved refrigerant recycling equipment.
USING R-12 REFRIGERANT.
1. Always wear eye protection when around air conditioning systems and R-12. The system's high pressure can cause severe injury to eyes and skin if a hose were to burst. R-12 evaporates quickly when exposed to atmosphere, freezing anything it contacts.
2. Use care when handling refrigerant containers. DO NOT drop or strike containers or expose refrigerant containers
Landlords and tenants alike just want a pleasant relationship, so that each can live in peace. No landlord should ever allow a tenant to move into their rental property without first requiring the prospective tenant to completely fill out a rental application.Among the important questions that should be answered on the application are:- Place of current employment? - Length of employment? - Name of bank? - Social Security number? - Do they have pets, if so what kind? - Number of vehicles? - How many occupants will live on the property? - Ages of occupants? - Name and address of current and prior landlords? - Have you been convicted of a felony? - Have you ever been evicted? - Are you currently engaged in criminal activity? - Have you been arrested and charged with a crime, but not yet convicted? - Are you in bankruptcy or plan to file for bankruptcy?A bold notice on your rental application form should read: Falsification of this information is grounds for a ten day Notice to Move if discovered later by the landlord or management.With the information found on the rental application the landlord can begin the screening process. It is the landlord's responsibility to be sure the tenant is the right person to occupy the home or apartment... and that the home or apartment is right for the app
Beware
When discharging air conditioning system, use only approved refrigerant recovery recycling equipment make sure you make every attempt to avoid discharging refrigerant into the atmosphere.
DISCHARGING THE A/C SYSTEM
The EPA indicates that R-11, R-12 and R-113 are very harmful to the Earths Ozone layer. Make sure you make every attempt possible to avoid discharging R-11, R-12 or R-113 into the atmosphere.
1. Remove service valve and install gauges. For high side gauge hose, Adapter must be used to connect to high side service valve.
2. Slightly open low side gauge valve and let refrigerant escape slowly without loosing refrigerant oil.
3. When system is nearly discharged, using approved refrigerant recovery recycling equipment, open high side gauge valve to release any pressure trapped in compressor. Close valves immediately after discharging to prevent entry of moisture.
DISCONNECTING LINES & FITTINGS
1. After system is discharged, using approved refrigerant recovery recycling equipment, carefully clean entire area around coupling nut to prevent dirt entering system. Always use two wrenches to avoid twisting or distorting lines and fittings
2. Cap or plug all LINES and FITTINGS immediately to prevent entry of air and moisture into system. Do not remove these caps until connections are being made make sure you make every attempt to avoid discharging refrigerant into the atmosphere.
COMPONENT REPLACEMENT
When components are replaced, system oil level must be adjusted. Add refrigeration oil to replacement component. See Compressor oil Check article, as well as, Component Oil Replacement Quantities" chart under "A/C SYSTEM SPECS" article in this HEATER AND AIR CONDITIONING

air conditioning systems and R-12. The system's high pressure can cause severe injury to eyes and skin if a hose were to burst. R-12 evaporates quickly when exposed to atmosphere, freezing anything it contacts.
2. Use care when handling refrigerant containers. DO NOT drop or strike containers or expose refrigerant containers to excessive heat. Containers must never be heated more than (52°C) 125°F. Never expose R-12 directly to open flame.
CAUTION: When R-12 is exposed to an open flame, drawn into a running engine, or detected with a Halide leak tester, poisonous phosgene gas is formed. Keep work areas ventilated.
INDIVIDUAL R-12 CANS
Disposable refrigerant cans have a flat type seal or a screw type seal, and proper can tap must be used for each type. Be sure sealing gasket on can tap is in good condition. A proper safety can tap will prevent refrigerant from flowing back into open can, as tap has a one-way flow control.
MULTI-CAN DISPENSING VALVES
A multi-can dispensing valve allows attachment of several cans of refrigerant, and is a good substitute when a bulk container is not available each leg has its own can tap cans are installed onto each leg of multi-can dispensing valve in the same manner as the individual cans.
CAN TAP INSTALLATION FLAT TYPE SEAL CANS
Recent findings by the EPA indicate that refrigerant is harmful to the Earth's protective Ozone layer. When discharging refrigerant avoid allowing refrigerant to enter the atmosphere. Refrigerant recovery system should be used when discharging the system.
First turn the handle outward to the fully open position. Securely engage locking lugs over the can flange, and lock them in place by turning cam lock or locking nut screw tap assembly into adapter so sealing gasket is fully seated against the can top.
Turn tap inward to pierce the can and close the tap. DO NOT open tap until ready to purge the service hose or dispense refrigerant into the system. Be certain tap handle is turned fully inward to the closed position. Check that locking base is turned to its outer limit. Securely engage locking lugs over the can flange. Turn entire tap assembly downward into the locking base to pierce the can. DO NOT open tap until ready to dispense into system.
DO NOT open high side hand valve while air conditioning system is in operation. This high pressure could rupture can or fitting at safety can valve, resulting in damage and personal injury.

The new trend in our society is working from home. Many women are leaving the corporate world to come home and care for their families, but they still desire to contribute financially. It can be challenging to work from home, especially for women who have children to care for as well.Is your wife is one of the growing number of work at home moms? Here are ten key tips on supporting her:1. Encouragement is keySometimes all that your wife needs in order to be successful with whatever she is working on is a little encouragement. Often times she won’t have anyone else around to give her the encouragement that she needs and you may be the only person that can give her the encouragement she needs.2. Help with whatever she is doingDepending on the business there may be extra work that could be done by you. For example, with my wife’s website, Christian Work at Home Moms (www.cwahm.com), she will often need someone to write a script, setup an email account, or proofread a document. Some of the tasks aren’t going to be the most glamorous but 5 minutes could save your partner hours of time and added stress.3. Be positiveIt's easy to be a positive influence on your wife and her business. Listen to her when she talks about her business. Don't put down her ideas for business growth - help her think of new ideas to help her business grow. Rememb

The variety of dog treat recipes available can be overwhelming. Even if you previously were unaware that dog treat recipes were even available, you may find that once you start looking for dog treat recipes, you find more recipes than you thought possible. There are a few tips for simplifying your search though that should make choosing a few dog treat recipes an accomplishable task.Before searching for dog treat recipes, it is advisable to do some preliminary research to compile a list of ingredients that you wish to avoid. This list could include ingredients that are harmful to dogs in general such as grapes, raisins, onions and cocoa, ingredients that your dog has a known allergy to and ingredients that have proven to be harsh on your dog’s stomach in the past. Compiling this list can help you to eliminate many dog treat recipes that contain these ingredients.You can also make the list of dog treat recipes more manageable by focusing on those that feature ingredients that your dog is particularly fond of. For example if your dog loves peanut butter or drools over bananas you might want to focus your dog treat recipe search on recipes that include these ingredients.There are so many dog treat recipes available that you may have difficulty settling on one recipe to try first. Tips such as eliminating recipes with certain ingredients and focusing on those with o

Treating ourselves to massage is one of the many gifts we can give ourselves; and one we fail to give often enough. It has been shown time and time again that massage holds strong physical and emotional healing properties; the likes of which can relieve stress, induce calm, and speed physical healing. But too often, we have neither the time nor the money to treat ourselves to a full body massage. Fortunately for the time-deprived among us, the massage chair has made the power of the healing massage both affordable and accessible.When people speak of a massage chair they are generally speaking about one of two things: the first is a portable chair that professional massage therapists use to stabilize their clients and provide full access to the back, neck, and head; the other is a vibrating chair that is controlled by the user to provide stimulus to particular areas of the body.The massage chair used by therapists is generally a collapsible piece that can be folded and taken along with the therapist to different appointments. Such a chair is often used in the workplace where the professional fifteen minute chair massage has become a popular perk to offer stressed out employees in the corporate world. The chair is designed in such a way that the client sits backwards on it. There is a seat on which the client straddles; a face cradle – a donut shaped cushion that allows
