 | 1. Can a liquid line solenoid be sized by knowing the connection size? |
|
No, a solenoid must be sized by knowing system flow and capacity in tons.
|
| 2. What is wrong if the outlet of a liquid line drier is frosted? |
|
The drier is restricted and needs to be replaced.
|
| 3. If system refrigerant charge is changed from R-12 to R-22 will a different distributor be required? |
|
Yes.
|
| 4. Does Flow Controls have a bi-flow suction line drier? |
|
No, a standard suction line drier installed in the common suction line of the heat pump is recommended.
|
| 5. How do you know if the liquid line drier should be changed? |
|
Change the drier if there is a wet reading in the sight glass.
|
| 6. Why does the sensing bulb on a TXV make a rattling noise? |
|
There is solid ballast in the bulb which will rattle if shaken under abnormal circumstances.
|
| 7. Can Flow Controls solenoids be exposed to rain and snow? |
|
No, all of Flow Controls solenoid coils are NEMA rated not weather proof.
|
| 8. Can I replace a TXV which has a bleed hole with a TXV which does not? |
|
Yes, if you add a hard start kit which contains capacitors and relays.
|
| 9. Will the AC system operate if the liquid line drier is installed backwards? |
|
No, there will be too much pressure drop.
|
| 10. Does an external equalizer line on a TXV balance system pressure? |
|
No, you need a bleed hole for that purpose.
|
| 11. What is the tonnage of an XB1019HC1B? |
|
This is a replacement power assembly number which cannot determine tonnage without also knowing the cage port number.
|
| 12. Can a BFK drier be installed in the suction line? |
|
No, there is too much pressure drop.
|
| 13. Is a 200RB solenoid bi-flow? |
|
Only if the bi-flow kit (KS30293) is installed.
|
| 14. Which way do you turn the superheat adjustment screw on a TXV? |
|
Turn the adjustment screws Clockwise to increase superheat Counter-Clockwise to decrease superheat.
