Winterizing 2019 Isata 3 FWM

LaWR - LongAndWindingRoad · 10-24-2018, 07:54 PM

We are winterizing and have watched the Truma video on the Dynamax website. We performed that task and did empty water out of the (Yellow) Easy Drain Lever (without getting the shower-haha!). Now we are going to use the "blow out the lines" method instead of pumping antifreeze through the lines. Antifreeze is only going down the drains to get to the P-traps/tanks/Valves. Should the Easy drain lever remain open or closed during the process of blowing?

Truma doesn't want you to use air pressure. If you have a water heater bi-pass valve, close it before using the air.

The valve mentioned above is behind the drawer under the kitchen cooktop.

You can close it....BUT leave the filter out. The filter is the seal. So if you close the yellow lever without the seal, water can still get out, but you can put the door back on.

There is room to store the Truma filter on the right side and still allow the door to close.
That way you won't have to look for it in the spring.

HELP! ASAP - So we pulled out the drawer and we see two shut off valves. One shut off valve is connected to a red tube and is labeled Hot water outlet and another shut off valve is connected to a blue tube and is labeled Cold water inlet.

Is there another single hot water heater bypass valve?? OR is it one or both of these valves mentioned above that we should shut off. Can you send a photo of this bypass valve if it is different from the two mentioned above. Need a visual because we are seeing no other valves besides those two behind the kitchen drawer.

Newbies here, We greatly appreciate everyone's help!!!!!

Ok, I don't think I have a bypass valve installed. I am also looking at the Truma manual and reading the Winterization section. I am not seeing anything that states we should NOT use the blow method. ??? I also read that winterizing with winterizing fluid is only possible with the bypass valve. We do not seem to have this valve so the only other way is to blow the lines free. I did read that you should not use more than 65 of water pressure through the city line but nothing about air and when blowing we have read not to use more than 40 as per the Dynamax website. I would think it would be OK. Thoughts???

The water by-pass valve is located behind the kitchen drawer, it's the valve on the left

Is that valve/hose going to the truma labeled "Cold Water Inlet"?

You only have the 2 levers, correct? Not the 3. We only have the 2. Just trying to get this straight.

Yes. There are only two valves. One valve is a shut off valve. I believe that is on the hot water outlet side of the water heater. The other valve redirects the incoming cold water away from the hot water heater but is not a true "shut off" valve.

It just has 2 shut off valves. Does not need the 3rd by-pass valve because it’s tankless.
