Whale pump help

[Foeboy]

Hi can anyone help? I have taken out a very old waste pump to a wet room and am attempting to install a new whale pump with a mira advanced. What I would like to know is do I have to install the whale transformer or will it work with the old set up?
Cheers

i would fit the new transformer. the reason being as soon as the job is finished the customer will ring up and say the pump isn't working and you will have to fit the new tranny any way so do it now.

oh and welcome to the forums
