HOW TO : Resun MD55

[erictck]

Guys, i'm at wits with the MD55

Currently, how do you guys induce the water intake so that the MD55 can run ? currently, the crude way, I use another pump to "feed" the water inlet of the md-55. Once it's capable of "######" it's own supply of water, i'll then pull the 2nd pump hose out of the md-55 water inlet.

I feel that this is very troublesome. Is there proper technic that i can apply ?

thanks heaps.

Regards,

Eric

I thought MD55 is pressurated and can suck water in a siphoning mode for people who don't drill hole in the sump. Isn't this true?

[weileong]

You still need to start the siphoning.

[patrick123]

How do you do that?

[weileong]

erictck has already explained the process in his first mail. Either you use a pump or you take the tubing out and slowly pour water in or use something to suck the air out. Once you start the siphoning then usually no problem with loosing it.

make sure your md55 is lower than your sump's water level, once u connect the pipings it pump will not empty even when it is switched off....

TRY this

step 2,b4 u restart,remove endcap and pour water in.then u switch on..like this..

[moron_clown]

but pls replace endcap before u switch on..

[typrobin]

wah.....good idea....

REMEMBER TO REPLACE THE END CAP....IF NOT WILL BECOME A FOUNTAIN!!!

it will not become a fountain lahz...dun scare ppl lahz...if u fail to replace endcap,the suction of air will eventually kill the siphon..

I think typrobin mistook it as a discharge.......:-P

hey guys,

fyi, i've already done what MC have recommended before i create this thread. Fyi, the air(pipe to the sump) will still cause problem. not able to suck the water. Pump is not strong enough to create a suction effect.

Eric,

Thats strange.

I just got myself MD55.

I did exactly as the diagram shown by mc.

and i do not encounter any problem.

The end cap of the T pipe need to be very tight.

there are a few things u need to take note of

1)all joints must be airtight.(i use a layer of silicon outside every joint)

2)endcap must be closed tightly.(i use pvc whitetape to wind around the diameter of the pvc pipe and then add a layer of pvc glue over.so my endcap will fit very tightly into the pvc pipe.)

3)u need to close the endcap BEFORE u switch on the pump

hope this helps

[erictck]

ok lah guys,

will give it another shot later when i'm free... will try to silicon all the joints.

thanks for the input. appreciate it...

guys,

was wondering if any of you happen to know if md-55 has thermal/fault protection circuit on board ? just incase the pump became over-heated due to loss of water pressure, will it shutdown ?
