Cleaning the Air Filter
The air filter should be cleaned as described below at intervals of approximately 100 hours. When
the filter is used for approximately 100 hours, the message "CLEAN THE AIR FILTER" appears
when the projector is switched on.
1 Switch the projector power supply OFF, and remove the power cord from the power outlet.
2 Clean the air filter with a vacuum cleaner.
3 Reset the Filter Timer using the function of the FILTER TIME on the OPTION Menu. Please
refer to the description of the "FILTER TIME" on the Table 9: MAIN Menu.
Replacing the Air Filter
Replace the air filter if contamination cannot be removed, or if it is damaged. To order a new air
filter see page 26 for contact information.
1 Switch the projector power OFF, and remove the power cord from the power outlet.
2 Remove the filter cover and the filter.
3 Replace the new air-filter and the filter cover.
4 Reset the Filter Timer using the function of the FILTER TIME on the OPTION Menu. Refer to
the description of the "FILTER TIME" on Table 9: MAIN Menu.

To get proper cool, keep the tips as follows:
1. Check air filter is cleaned. 2. Check indoor coil is cleaned. 3. Check indoor blower motor is working. 4. Keep in cool mode. 5. Set temp minimum 3 degrees less than room temp.6.Check compressor is working with correct pressure.

Thanks. Helpful?

Good luck.

The de coming back into the pump isnt anything serious, there may be a small air leak causing the water in the filter to drain into the pump.

As far as having to bump every couple of hours... is the pool really dirty?

Is your pressure gauge broken? Turn off the pump, does the gauge drop to zero? Alot of times they dont drop to zero, so when you hit 25psi it may really only be 15. Happens alot actually.

If pool is clean and clear and the gauge is fine... have you ever taken apart the filter and cleaned the de fingers? If not, i would take it apart, rinse all of the fingers and then let them soak over night in a filter cleaner solution. This cleans them much better then a plain garden hose spray. After they soak, spray them down again, add new de and you should be good to go....

When the pressure goes up, try this. Pour some muriatic acid in the skimmer. (about 1/2 bottle) Let pump run for a little bit,(long enough for acid to get into filter)then shut off pump for 5 minutes or so. If pressure goes down to where it should be when it's turned back on, it needs to be disassembled and cleaned and then acid washed.

Certainly sounds like a filter problem. Here's a couple of things to try.#1. i don't know how you cleaned the filters but clean them again with a good filter cleaner/degreaser.#2. After a good cleaning, get a bucket large enough to hold the filter fingers in and give them an acid bath. They recommend a 20 to 1 ratio of water to acid (muriatic) but I personally don' think thats strong enough. Use a good amount of acid and let the fingers soak for a good ten or fifteen minutes. (always add acid to water, not water to acid) Rinse and reassemble filter. If that does'nt solve problem, I think it's time to replace filter.

Tune Time.
1)new spark plugs properly gapped.
2)new air filter (check every 35000 miles)
3)new fuel filter (every 35000 miles)
4)1 bottle of STP fuel treatment (red bottle) 4x a year.
5) oil and filter change (castrol or another good quality oil every 3-4000 miles.
6)proper air pressure in tires (check every 2 months
7) service transmission every 40000 miles or less.

New oil and filter
8) new plug wires every 80000 miles.

Gas cap has no bearing,lol. Check the wiring under the battery tray. They're notorious for corroding through the wiring & cause a short to the ecm. This results in retarded timing & wierd stuff going on. Write back if you need more. Old car,lots to check.

You must set the pressure! If the heater runs with your compressor connected, but won't when the pressure is disconnected, well.......

Setting the pressure is easy!
