Wood Floor

Initially remove any dust and debris from the floor surface and follow the notes on preparing

the surface in section 3. Then check the flexi-fast mat or cable resistance against the figures

given in section 2, also check the temperature probe resistance (approx 110kΩ at 20°C for

RAMSES 714 A and TPT88, 10kΩ at 20°C for TPT1 and TPT44, decreasing with increasing

temperature). If the readings are okay proceed with laying the flexi-fast mat or cable:-

a. Cable.

During the installation wear soft soled shoes and avoid treading on the probe or any

of the cables. Working to the planned layout make grooves for the cold cable and the probe

with flying lead to give the same overall height above floor level as the heating cable then

remove debris. Tape the temperature probe and flying lead as well as the cold cable into their

respective grooves using the tape provided. When positioning the heating cable ensure that

it is well clear of the temperature probe (see figure 3). Tape the cable to the floor according

to the plan developed in section 4 with an 82mm cable spacing as shown in figure 1.

The cable should be taped at every bend and also five times along the runs between bends

as shown in figure 6.
Check the cable and probe resistance and then coat the cables and adjacent floor with a thin

layer of adhesive with the essential flexible additive.
The cable and probe resistance should be checked again after the adhesive has set.
If the cable and probe resistance is okay the adhesive with the essential flexible additive should

now be spread evenly over a section of the floor until the cable is completely covered, then slab

laying or tiling is carried out over this section. The process is repeated section by section until

the floor is completed.
When grouting it is essential to use a flexible additive mixed with the grout. The cable and

probe resistance should be checked again on completion of the grouting.
NOW ALLOW 10 DAYS FOR THE SCREED TO COMPLETELY SET AT A NORMAL ROOM

TEMPERATURE BEFORE COMMISSIONING.

b. Flexi-Fast Mat

During the installation wear soft soled shoes and avoid treading on the probe or any

of the cables. Working to the planned layout make grooves for the cold cable and the probe

with flying lead to give the same overall height above floor level as the heating cable then

remove debris. Tape the temperature probe and flying lead as well as the cold cable into their

respective grooves using duct tape. When positioning the flexi-fast mat ensure that the heating

cable is well clear of the temperature probe (see figure 3). Drill two holes 6mm dia. at least

17mm deep close to the ends of each run of flexi-fast mat. These are to locate the push-fit

plugs supplied. They should engage with each of the two outer runs of webbing within the

flexi-fast mat (not the cable). The start of each run of flexi-fast mat should be placed in position

smooth side down and the plugs pushed home hard trapping the webbing under the heads of

the plugs. The mat should be stretched to close to its maximum length to give 133W/m

2

and

two more plugs pushed home into the pre-drilled holes at the end of the run. Cut the webbing

(avoiding damage to the heating cable) to reverse direction or avoid obstacles using the

techniques shown in figures 4 and 5 whilst continuing to fix further runs of the flexi-fast mat.

When reaching the last two or three runs the stretch can be adjusted to use up the complete

cable (count the cable loops on one side of the remaining mat length to do this).
Check the cable and probe resistance and then coat the cables and adjacent floor with a thin

layer of adhesive with the essential flexible additive.
The cable and probe resistance should be checked again after the adhesive has set.
If the cable and probe resistance are okay the adhesive with the essential flexible additive

should now be spread evenly over a section of the floor until the flexi-fast mat is completely

covered, then slab laying or tiling is carried out over this section. The process is repeated section

by section until the floor is completed.
When grouting it is essential to use a flexible additive mixed with the grout. The cable and

probe resistance should be checked again on completion of the grouting.
NOW ALLOW 10 DAYS FOR THE SCREED TO COMPLETELY SET AT A NORMAL ROOM

TEMPERATURE BEFORE COMMISSIONING.

Concrete or Screed Floor

Initially remove any dust and debris from the floor surface and follow the notes on preparing

the surface in section 3. Then check the flexi-fast mat or cable resistance against the figures

given in section 2, also check the temperature probe resistance (approx 110kΩ at 20°C for

RAMSES 714 A and TPT88, 10kΩ at 20°C for TPT1 and TPT44, decreasing with increasing

temperature). If the readings are okay proceed with laying the flexi-fast mat or cable:-

a. Cable

Proceed as for wood floor (a) except use a cable spacing of 62mm (see figure 1).

b. Mat

During the installation wear soft soled shoes and avoid treading on the probe or any

of the cables. Working to the planned layout make grooves for the cold cable and the probe

with flying lead to give the same overall height above floor level as the heating cable then

remove debris. Tape the temperature probe and flying lead as well as the cold cable into their

respective grooves using duct tape. When positioning the mat ensure that the heating cable is

well clear of the temperature probe (see figure 3). Fix the matting smooth side down using the

three runs of adhesive tape already fixed to it. This is best achieved by removing the backing on

this tape over a short length then fixing the mat down before moving to the next section. Cut

the webbing (avoiding damage to the heating cable) to reverse direction or to avoid obstacles

using the techniques shown in figures 4 and 5.
Check the cable and probe resistance and then coat the cables and adjacent floor with a thin

layer of adhesive with the essential flexible additive.
The cable and probe resistance should be checked again after the adhesive has set.
If these are both okay the adhesive with the essential flexible additive should now be spread

evenly over a section of the floor until the mat is completely covered then slab laying or tiling is

carried out over this section. This process is repeated section by section until the floor is

completed.
When grouting it is essential to use a flexible additive mixed with the grout. The cable and

probe resistance should be checked again on completion of the grouting.
NOW ALLOW 10 DAYS FOR THE SCREED TO COMPLETELY SET AT A NORMAL ROOM

TEMPERATURE BEFORE COMMISSIONING.

c. Flexi-Fast Mat

Proceed as for wood floor (b) except the degree of stretch is low to give 200W/m

9. Guarantees

Figure 6

Note: The 10 year guarantee cover of mats and cables as components is not effective

unless the installation is protected by an RCD.

The installation of the Controller and RCD must be carried out according to their

respective instructions and the installation must comply with the current I.E.E. Wiring

Regulations. If there is any doubt about how to proceed please contact the Helpline

on 020 8450 0515 or a competent professional person.
Fix the controller and RCD in the required positions. We suggest the controller is mounted

around head height for ease of programming. Terminate the incoming supply leads to the RCD

in accordance with its instructions. Connect the RCD output to the incoming supply terminals of

the controller in accordance with its instructions. After measuring and recording the overall

cable resistance the cold cable may now be connected to the output terminals of the controller,

shortening the cold cable as necessary. After measuring and recording the temperature probe

resistance and the approximate room temperature the probe flying lead may now be connected

to the probe terminals on the controller, shortening the flying lead as necessary.

Referring to the appropriate instructions turn the RCD on and set the controller to the

maximum temperature in continuous operation. There should be a noticeable change in the

floor surface temperature after one hour with a wood floor and up to five hours with a

concrete floor.
The controller should now be adjusted to a temperature giving the required comfort and the

timing (if incorporated) set as required.
We recommend a temperature setting of 28°C

Do not cut the heating cable.

Do not leave surplus matting or cable rolled up under units or fixtures – use the right size.

Do not cross any cables.

Do not switch mat or cable on until 10 days after fitting.

Do not cut or prepare tiles etc on top of the finished area.

Do consult the Helpline or a competent professional person if you are unsure how to proceed.

Do use an approved flexible additive mixed with screed/adhesive.

Do use an approved flexible additive mixed with the grout.

Do cover the area where mats or cables have been laid for protection.
