DRAWING NOTES:
THE PIPEWORK SIZE IS GENERIC AND NOT THAT OF A PARTICULAR MANUFACTURERS
RANGE, UNLESS SPECIFIED.
PRESSURE TESTING SHOULD BE CARRIED AFTER LAYING THE PIPEWORK. ALL UFH PIPE
TO FLOOR FIXING / SCREEDING. PRESSURE TEST SHOULD BE LEFT UNTIL CONNECTION TO
THE UNDERFLOOR HEATING PIPEWORK SHOULD NOT BE LAID BELOW A ROOM TEMPERATURE
OF 0`C. WE WOULD ALSO NOT RECOMMNED THAT SCREEDS ARE LAID WHERE THE ROOM
TEMPERATURE IS BELOW 5 degC.
CURING TIMES OF ALL SCREEDS SHOULD BE ON THE RECOMMENDATIONS OF THE SCREEDER.
ONCE THE CURING PERIOD HAS BEEN ACHIEVED, THE FLOW WATER SHOULD BE SET
AT APPROX 25 degC AND RAISED 5`C EVERY OTHER DAY UNTIL THE DESIGN FLOW
TEMPERATURE IS REACHED.. THIS PROCESS THEN SHOULD BE REPEATED BY REDUCING
THE FLOW TEMPERATURE BACK DOWN TO 25`C.
IF TIMBER FLOORING IS TO BE LAID UPON HEATED SCREEDS, THESCREED MUST BE CURED
AND CONDITIONED PREVIOUSLY TO MANUFACTURER'S SPECIFICATIONS. IT IS NOT
RECOMMENDED TO LAY NATURAL WOOD FLOOR COVERINGS THAT MAY HAVE A MOSITURE
CONTENT EXCEEDING 8-9% (BY VOLUME) AS THE RISK OF WARPING AND SHRINKAGE
DAMAGE WILL BECOME UNACCEPTABLE.
IF CARPET IS TO BE USED AS THE FINAL FLOOR COVERING IT IS IMPORTANT THAT
THE THERMAL RESISTANCE OF THE UNDERLAY DOES NOT EXCEEDA TOG RATING OF 1 - 1.5.
ANYTHING ABOVE THIS RATING WILL AFFECT THE HEAT OUTPUT FROM THE UNDERFLOOR
FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN THE DESIGN NOT
BEING MET OR EVEN DAMAGE TO THE FLOOR COVERINGS
FLOW RATES AND PRESSURE DROPS ON DRAWING GIVEN PRIOR TO INSTALLATION OF
SYSTEM ARE BASED UPON STANDARD DESIGNS AND CIBSE GUIDELINES..
AIR TEMPERATURE THERMOSTATS ARE TO BE POSITIONED APPROXIMATELY 1.6M FFL,
AND SHOULD AVOID DIRECT SUNLIGHT IF POSSIBLE..POSITIONS ON DRAWINGS ARE ONLY
ALL HOLES TO BE CUT PRIOR TO START OF UFH INSTALLATION. ALL HOLES TO BE
CUT ACCORDING TO DIMENSIONS SHOWN ON SCHEDULE, AND 50MM (OR THICKNESS OF
INSULATION) FROM BASE OF WALL.
THE TEST HAS BEEN COMPLETED.
SHOULD NOT EXCEED 1 BAR (AIR) OR BETWEEN 3 AND 4 BAR (WATER) PRIOR

SCREED FLOORS:
WE WOULD RECOMMEND THAT SCREEDS SHOULD BE COVERED IF HEAVY EQUIPMENT IS
TO BE USED, SUCH AS MOBILE TOWERS, OR VEHICLED TRAFFIC.

CARPETS AND UNDERLAYS:
HEATING SYSTEM.. CONFIRMATION FROM THE MANUCTURER / INSTALLER SHOULD IS
RECOMMENDED.
UNDERFLOOR HEATING :
ALL UNDERFLOOR CIRCUITS ARE INDICATIVE LAYOUTS AND WILL BE SUBJECT TO SITE
CONDITIONS. IT IS HIGHLY RECOMMENDED THAT SHOULD FIXINGS BE REQUIRED WITHIN THE
SCREED, THAT THEY ARE MARKED OUT PRIOR TO THE UNDERFLOOR HEATING.
INSTALLATION.
BUILDERS WORK:
CONTROLS:
INDICATIVE AND EXACT MARKING OUT SHOULD BE CARRIED OUT ON SITE.
ALL FITTING AND WIRING SHOULD BE THE RESPONSIBILITY OF THE SITE ELECTRICIAN.
ALL WIRING DIAGRAMS ARE CORRECT AT TIME OF DRAWING ISSUE, BUT IT IS THE
RESPONSIBILITY OF THE ELECTRICIAN TO MAKE SURE ALL ITEMS ARE CORRECTLY INSTALLED.
