DITRA-HEAT-E-HK - How to install

Electrical installation must be carried out by a qualified electrician in accordance with BS7671. Heating cables must have a multi-pole circuit breaker with a contact distance of at least 3 mm per pole. To protect against inadvertent contact, an RCD (IF circuit breaker) with trip current of IΔN ≤ 30 mA must be installed.

More information about installing the heating cables and installing and configuring the thermostat can be found in the respective installation instructions.

Heating cable installation

1. 1. For floor installation, the heating cables can be installed immediately after gluing the DITRA-HEAT uncoupling mat, using a float or roller.
      For wall installation, heating cables are installed as soon as a suitable adhesive bond is achieved.
      Heating cables must never overlap or touch each other.
   2. Create a corresponding recess in the sealed end area of ​​the cable.
      Note: Use the Schlüter-DITRA-HEAT-E-CT cable tester to continuously measure the resistance of DITRA-HEAT-E-HK electric heating cables. The device monitors the resistance of the heating cables throughout the installation phase and alerts the installer with an acoustic signal in the event of damage.
2. Floor areas:
   The pin spacing on the decoupling mat is 3 cm. Installation spacing in the floor area must be

• at least 9 cm (about every third pin – equivalent to 136 W/m²) One
  Closer installation spacing – especially in floor areas – can cause overheating and cause damage to building structures.
  Avoid stepping directly on heating cables during installation work.

3. Wall areas:
   Depending on available space, desired surface temperature and required thermal power, installation spacing in wall areas can be

• 6 cm (around every second pin – equivalent to 200 W/m²) or
• 9 cm (about every third pin – equivalent to 136 W/m²)

4. The transition from the heating cable to the connecting cable (sleeve) is indicated by a label. The 'cold leg' (4 m) must be connected directly to a junction box or thermostat. The 'cold leg' can be shortened as much as possible. length of 1 m before assembly. Heating cables must not be shortened.

Thermostat:

DITRA-HEAT system heating cables can only be operated with DITRA-HEAT-E thermostats.
