Fitting your product and choosing the correct length

Although Frostsafe is simple to fit, it’s important to follow a few key rules to ensure your pipes are safely protected for years to come. We’ve listed the main points below, and full instructions are included with the Frostsafe units.

For pipes up to 22mm in diameter you only need one run of Frostsafe running along the base of the pipe, although you can double-up and have runs of the heater at 4 o’clock and 8 o’clock if desired. You should select a Frostsafe unit between the same length as your pipe, and twice as long.

For larger pipes Frostsafe must be spiralled around the pipe and you should use a length of Frostsafe that is at least 10% longer than the pipe you are looking to protect, and it can be up to twice as long if desired.

• If you have a non-metallic pipe, you should fix aluminium tape along the pipe where the Frostsafe unit will be placed to help conduct the heat into the pipe.
• If you are using a single run of the heating cable you should run this below the pipe at around the 4 o’clock position, and if you are running excess cable back along the pipe this should be secured at around the 8 o’clock position.
• If you are protecting a pipe with a diameter of 23mm and above, you should spiral the heating cable around the pipe as evenly as possible.
• The heating cable should be held in position at regular intervals with cable ties, aluminium, or glass-fibre tape, and it is important to ensure that the heating cable never crosses itself as this could cause it to burn out.
• Frostsafe must not be installed in ambient temperatures below 5°C, or where the pipe temperature is ever expected to exceed 65°C.
• Once the heating cable is secured in place the pipe and heater should be covered with a maximum of 13mm of non-combustible pipe lagging, and the warning stickers supplied with the Frostsafe unit should be stuck to the outside of this lagging.
• All Frostsafe units must be protected by a suitably rated fused spur and a 30mA RCD. We recommend that the installation of these units is carried out by a qualified electrician.
• Care should be taken to protect the system from physical damage, for example by tool damage, animals, or vehicles.
