My wall split a/c 24000 btu work about 1 hours or more after no cooling and u can see frost in the indoor coil and on the coppers on out door unit and i have low pressure 40

Low pressure and frost on your indoor coil with the copper pipe to your outdoor unit is almost guaranteed a low refrigerant charge. It can also be a bad metering device. You will need to check you high and low side pressures to be sure and make sure you let the frost thaw before checking pressures.

Gree 18000 Btu Air Conditioner , f2 appears on display

F2 is an indoor pipe sensor fault. You will need an air con tech or electrician to do this as the sensor is wired into the indoor board. Gree parts can be a bit difficult to obtain but a similar sized pipe sensor from an LG or Teco unit will work. You may have to "splice" the new sensor onto the existing pipe sensor wiring as the connection to the indoor board will likely be different. Contact LG or Teco for your colsest parts outlet or buy direct from them.

What diameter size galvanized pipe do i use for installing my new Raypak 266,000 btu gas heater?

Refer to the owners manual as the pipe size is dependent upon the length of run the pipe will be, the pressure your fuel system operates at and the fuel you'll be using. If you do not have the manual you can find a copy here. Refer to page 20.

What size gas line for 400,000 btu water heater

Thank you for posting your question here on

Is it Natural gas or LP gas?
What pressure does your gas provider supply it with? (It will usually be low pressure, ~14"WC if NG)
How far from the access point you will get gas from to the heater?

Once you have answers for these three questions use the installation guide found on pages 13-14 of this manual to determine the proper gas line size. Be sure if you use a different material pipe, like CSST, you adjust the pipe size based on manufacturer's recommendations. 1" copper and 1" CSST are NOT equivalent!

If this answer does not fix your problem, please comment with additional details prior to rating the answer. You may also contact me thru our website at Positive feedback is appreciated once your problem is solved!

Wansa split a\c outdoor unit both pipe size

It depends on the make model of your unit , the capacity of the unit. It will be best to check the pipe sizes that are on the outdoor unit and the indoor unit that needs to be connected.
The copper pipes can then be decided after checking the length of your fitment.

Oil trap for 2 ton split unit

Pipe size is okay, not that I know any better than the manufacturer, but I would recommend at least two and possibly even three oil traps in the vapor line on the way back up.
