Pre-installation requirements
Planning
Before installing MHP panels ensure you have planned out the
positioning of the required panels avoiding all other services such
as electrics, gas and water supply.
You will not need to do any specific preparation for the
installation in a new build property as there will be no ceilings
or floors in place.
For existing room refurbishment, you will need to take up your
floor if fitting from above or take down the ceiling if fitting from
below. Ensure that the area where the MHP panels are to be
positioned is free from any debris before commencing installation.
Installation
Installation from above
To install MHP panels from above simply fit support bearers to
each side of the joists. These support bearers should be positioned
30mm from the top of the joist and the MHP panel is then simply
laid on to these supports.
Installation from below
When installing MHP panels from below you will need to mark
out the positioning of the panels to ensure you have them
situated in the correct places for heating the room above.
Once you have checked the marked out positioning, the MHP
panels can be slotted into place and fixed to the underside
of the floor using 1¾” x 8 woodscrews with M6 x 30 dia washers.
It is advisable to use 6 fixings per panel ensuring you avoid the
moulded pipe marking on the underside of the panel and fix
each panel securely.
IMPORTANT NOTE:
Polystyrene can cause deterioration to cable
insulation when it comes into direct contact with it.
Always ensure that electrical cables are not in physical contact
with the MHP panels using tape or a polythene strip.
Finishing
Once you have connected your system up to the manifold and
tested it you can then finish the room by fitting the floor or ceiling
in the normal way depending on whether you have installed MHP
from above or below.
Testing
Where possible installations should be tested at 20°C to
18 bar pressure. Any installations once connected to the manifold
have a maximum test pressure of 6 bar.
