9k btu liquid pipe can use hand to bend. For Gas pipe, recommended to use bender.
And for G22 piping, it's thick. Bending if use hand and not skillful enough, the pipe will suddenly bend inwards and instead of a nice curve, it will be a dent. This is also one of the possible cause of condensation as gas flow is reduced @ that portion and it will be very cold @ that area.
My advice, get a good installer (which comes @ a higher price). Leave it to them to do the job. Cos if you watch them install and "teach" or "request" them what to do. This might make them very uncomfortable to work. There are many ways for them to sabo u.

The installers are just workers or contractors of the company. Treat them a bit nice, like buying lunch for them. Tell them that this aircon system might last you for 5-10 years and hope they can do their best to lay the pipings nicely so that it can last you through the years w/o much problems.

No person in the service line wants a demanding/"smart alec" customer. Treat them nice and the serviceman might be willing to go the extra mile for you.

Juz my views...
Hi, chunlianghere, terumo, thesingingbard,

Thanks for all your advices.

I also don't wish to be a demanding/"smart alec" customer "teach a father how to corpulate".

I will be there just to over-see the renovations and not give them too much troubles.

I understand what terumo is saying. Yes, if we nasty with them (be it the air-con installers, the carpenters doing my kitchen cabinets), there are many many ways that they can sabo the renovations.

Yes, I understand too, that we have to treat them nicer so that they might be willing to go the extra mile for us.

I have already make up my mind to buy some drinks or snacks up for them when I go "visiting" the renovations.

I know that if we treat them nice, they will do a nice job for us.

I don't mind spending a little bit of money to buy drinks for them in exchange for a trouble-free renovations.

Thanks very much for all your advices.

Really appreciate it very much.

Cheers.
