Hi Guys,

Ive just bought this pump from RO Man and its supplied with no power lead and a worrying lack of instructions. 

http://www.ro-man.com/shop/product_info.php?cPath=28&products_id=245

The instructions are so bad that I about to construct it using only the picture on the website - the only thing Im unsure of is which end is water in and what end is water out?

If anyone has any experience of this or a similiar pump your input would be appreciated

Regards

Alistair

Would have thought there was an arrow on the base of the pump showing which direction the water flows

I have the same pump the water inlet is the bottom one, mine also came without a power lead I just cut the end off an extension lead and used that. use plenty of ptfe tape on the fittings otherwise it leaks like a seive.

Thanks Chris's 


Chris@c.m.s for once I am actually using the PTFE tape, they sent 4 rolls of the stuff so I thought I best take the hint 

It mentions somewhere in what they call instructions that you should fill the body of the pump with water before using it, can you tell me what to disconnect to fill it up

Cheers

I hadnt a clue what they ment by that because if its all connected up before you turn it on then surely the mains pressure will purge it when you run water through it, thats all I did anyway, saying that mine is noisy but I think there all like that.
 

[Alistair@AWC]

Well yeah its only gonna run dry for a second or so, so I dont see what damage thats gonna do, its probably so they can say you've invalidated the warranty if anything does go wrong.

Well ive got it all connected but to be truthful im quite scared of turning it on 

[chris@c.m.s]

Run the ro through it first without turning the mains on that way at least you find leaks at low pressure, good luck I was worried about flicking the mains switch too .

[Alistair@AWC]

Cheers Chris,

Just one final question before I flick the switch and run 

The optimal and maximum running pressure for the Merlin is 70psi, now this pump can work upto 95psi but as far as I can see there is no dial/switch to adjust the pressure - what have you done if anything about this.

I havent needed to tackle that problem because I have a 4040 Ro.   

[Alistair@AWC]

Cheers Chris,

Im starting to wish that was the route I took.

Well I was getting water at about 58 TDS then ive flushed the system about 5 times and got it down to about 30 TDS and after giving the pump a quick run tested the water again and its still about 30 TDS but im sure I havent given it enough time to make an effect.

Although your right it is bloody noisey dont think the neighbours will be to happy if I start running it overnight
