Plumbing
4.6. The Power Pack should be fitted as close as possible to the point to be
supplied, ideally within 4/5 feet as the length of the outlet pipe affects the initial
temperature from the outlet. If used to supply a shower, the Power Pack must be
installedoutsidetheshowercubicleorshowerroom.
4.7. Decide where to connect to the water mains for your feed to the Power Pack.
