CAN I USE CLEANER FOR SERVICE THE INDOOR AND OUT DOOR UNIT, CLEANER HAS CHEMICAL SENSITIVITY THIS WILL BE GOOD FOR UNIT OR NOT?


find an air conditioner service shop in your area as there are non caustic products available to use to clean the fins on the evaporator and condenser
places that sell compressors , driers, evaporators condensers to the air con trade will be the best place to go to
I use a product called viper E+ enzyme power which you spray into the fins of the units and it actively cleans for hours
it is a non rinsing cleaner made by refrigeration technologies part no rt350g
site www.refrigtech.com
not cheap but very effective

What would be causing Reverse cycle Inverter split system to leak? I have checked filters are clean and that there is no blockages of outdoor drainage hose?


The accumulated water has no drain to flow through, and is backing up in the indoor unit. Find the source of the clogged drain, and your problem will disappear. If you are lucky, you can pour a little bleach or peroxide in the indoor unit's cooling coil and the chemical will eat your clog. Otherwise, mechanical cleaning may be necessary. Check your installation manual to see how your unit is supposed to be plumbed.

Air con dead


Larger split system air con gets power from the external unit while smaller air con gets power from the internal unit. Can you find any power switch or power socket/plug around the external or internal units?

We have a msz-ga80va split cycle, indoor unit runs for about 5 minutes without cooling then cuts out, outside unit doesn't kick in at all


Just had the same thing happen to us with the same model (right on Xmas day).
Checked the circuit breaker is on in the fuse box. Power is on to the external unit. Filters are clean.
Internal unit activates... both indicator lights on. After 5 minutes blowing air it stops and the right indicator light goes out and the left indicator light blinks constantly.
The troubleshooting guide inside the internal unit (under the outer cover you open to clean the filters) suggests that 14 blinks is an abnormality with the external unit and refer to service manual.
Think we'll be calling a technician.

5 ton split LG UNIT brand new about 1 year old.


Look up the term BLACK DEATH.


90-100 psi is very high on the low side.

Without spending too much time,I would pull a vacuum to -28 inch of mercury and let it sit over night.

Monitor the manifold garage for leak. (rise of inch of mercury)

My bet is the low quality LG compressor's worn out metal part is in the condenser.

Blockage will increase the low side PSI.

You can buy HVAC blow out can/chemical to clean line before you vac and fill the refrigerant.

Please let me know what's you founding is on reply.

How to clean the filters in split airconditioners


Check on top of the indoor unit. On some models, the filter will slide out from there without having to open the cabinet. On others you will need to pull on the top front and the panel will swing down (it will be hinged) and the filter will be behind that panel.

Hey traboH - thanks and we do need to get a chemical supplier - but this machine does not have automatic dispensers - how else might I add soap? Thanks, robin879


It's acceptable to just pour the proper amount of detergent right into the unit every time you wash a load. However, there are two things to consider.

1. Without pumps, it is important to ensure that your final rinse temperature is, at minimum, 180 degrees for proper sanitation of your dishware. If you have a LXiGC, as you've indicated, you'll have trouble doing this because that unit does not have it's own booster heater to maintain such high temps. Usually, sterilization is achieved through the use of a chemical sanitizer, delivered via a pump during the rinse cycle, on that particular model.

2. Also, it will be impossible to properly deliver rinse aid (jet-dry) to the machine without pumps. This may lead to noticeable "spotting" of your glassware.

Adding pumps to the unit is an option I would seriously consider. Your most economical route would be to have your chemical company install their pumps externally. Your local Hobart office can offer you the addition of chemical pumps, as well, but you'll pay a premium price for them.

I'll add, if you do decide to get the pumps, insist that the proper ratio of chemical is being delivered (achieved via pump programming). It's not uncommon for the pumps to be improperly programmed and excessive amounts of chemicals consumed. These guys are, after all, in the chemical SALES business.
