Installation - Mira Zest 7.5 Installation, Operation And Maintenance Manual

Mira Zest 7.5 and 8.5
WARNING! Isolate the electrical and water supplies before proceeding with the installation
of the appliance.
1. Decide on a suitable position for the appliance (minimum distance of 200 mm from
the ceiling to allow for cover fit and removal). The position of the appliance and the
shower fittings must provide a minimum gap of 25 mm between the spill-over level
of the shower tray/bath and the handset. This is to prevent backsiphonage (refer to
Figure 1).
2. Remove the three cover retaining screws.
3. Remove the cover.
4.
Remove the service tunnel.
5. Determine the direction of the inlet water supply: top (falling), bottom (rising), or
back inlet .
Note! Make sure that the back inlet does not go directly back into the wall and that
you use a suitable compression fitting.
6. Remove as appropriate, the thinned sections of the appliance case, to allow the
supplies to enter the product.
7. Thoroughly flush the mains-fed cold water supply pipe. The supply must be
clean and free from debris BEFORE connecting the appliance.
8. Offer the appliance up to the wall and make sure that sufficient electrical supply
cable is available for terminal block connection. Temporarily connect the mains-fed
cold water supply pipe. Mark through the casing the position of the three fixing
holes. Remove the appliance from the wall.
9. Drill and plug the three fixing holes. Secure the appliance to the wall with the screws
provided. Alternative fixings (not supplied) may be necessary for some wall structures.
10. Install the mains-fed cold water supply pipe.
11. Make the connection to the mains-fed cold water supply pipe.
12. Bring the electrical supply cable into the case through one of the cable entry points.
13. Strip back sufficient of the outer cable insulation to enable routing to terminal block.
14. Fit an earth sleeve to the earth conductor. Connect the conductors firmly into the
terminal block. Make sure that the bare cores of each conductor are securely trapped
within each conductor clamp.
