Around here we go by the NFPA31. and 211? For chimneys and manufacturer instructions. I think the main issue you will have is if it is running a long way through an unconditioned space it will need...

So what happened? Are you still there or did you get it going?

You can get this at a hardware store also if it is easier. If the supply house is where you end up ask for a Beckett bulkhead adaptor.

You MUST check pump pressure at the nozzle line. This is the proper way of verifying oil flow to the nozzle and you should check it every time. Period. Did you set the z dimension? If the drawer assy...

What started this? Are you there for an annual service or was it out when you arrived?

I didn't see the model or vintage of the unit but we have 85 carriers on this one roof. And 15 of them are 50TJ028600 in the 1996&1997 range. I have probably had this problem with this model 7-8...

You should move to NH. You can do anything you want in your own home as long as it is by the code. The only HVAC requirement to buy parts and refrigerant is a card from the EPA stating that you...

Are those fittings JIC hydraulic flares? If so you should be able to get them anywhere they make hydraulic hoses.

Do you need a license of any kind in India to service equipment with refrigerant in it? Just curious. Thanks

An ultrasonic leak detector might work. Used for diagnosing steam traps and bearing noises etc.

How come the minerals or TDs does not plate out when misted into the air flow? Is it just cooling the air before it goes through the condenser? How do you keep the water from hitting the coil?

...

I agree Condensate definitely would better than spraying hard ground water on warm aluminum coils. How do you distribute the water over the coil? Do you use a condensate pump?

How deep of a vacuum did you have to achieve for this to work and what size pipe did you use?

You should contact the manufacturer about outside venting. Many systems are ul listed and legal for use with PVC pipe whether it is a good idea or not. Some manufacturers have optional concentric...

Just a thought, how about attaching something to the pipe to help dampen the natural resonance? Maybe armaflex sheets or bubble wrap. I would think If either were tightly glued to the surface of the...

That kind of noise will send certain customers right to the nut house huh?
