Installation Info

The below information is a general guide and not for any specific air con system.

The installation will require the services of an F-GAS registered engineer, who will be trained and have experience of installing these systems

Indoor Unit - Pre-checks

  • Ensure there is no source of heat or steam nearby.
  • Ensure there is nothing stopping the installation of the unit before drilling holes.
  • Do not mount above a shelf or a cupboard that could restrict air circulation.
  • For the unit to work effectively in cooling mode, it must be mounted 2m off the ground or above head height.
  • Make sure the installation wall is suitably secure.

Outdoor Unit – Pre-Checks

  • If you erect a canopy to protect the unit from rain and sun, DO NOT obstruct the heating dispersion for the condenser.
  • Don't keep animals or plants near the outdoor unit as the hot and cold air discharge will cause discomfort.
  • Make sure to have the distance specified in the installation manual (provided by each manufacturer) between ceiling, wall, furniture and other obstacles.
  • Do not mount near flammable gas tanks.
  • The mounting brackets/mounting plate or mounting feet for the unit must be secure, flat and level.
  • The outdoor unit must be secure, flat and level.

Installation Of The Air Conditioning System

Your chosen F-GAS registered engineer will aid you to select the best location for the indoor unit (Evaporator) and outdoor unit (Condenser) to be positioned.

You may also need to employ the services of an electrician, to supply mains power to the outdoor unit’s location. If in doubt, discuss this with your chosen air conditioning engineer.

The engineer will likely book the installation in as a half day or full day job, depending on the chosen locations and complexities of the installation.

They will usually supply all parts and sundries required to complete the job, as most systems available are only supplied with an indoor unit, an outdoor unit and a remote control. There are various extra parts required to install an air conditioning system, this can include:

  1. Brackets or Feet
  2. Pipework and Lagging
  3. Electrical Cable
  4. Trunking
  5. Condensate Pumps
  6. Fixings and Fasteners
  7. Additional Refrigerant
  8. Plus many more items, depending on the type of system(s) being installed

It is best to speak with the engineer when discussing the quote given to carry out the installation, to see what is included.

Specialist tools are required to commission an air con system which your engineer will bring with them to install you system. Systems must be strength and pressure tested and held on a vacuum for long periods of time, to ensure they are going to operate effectively as possible and eliminate the risk of leaking refrigerant into the atmosphere.

Upon completion of the installation the engineer should issue you an F-GAS Commission Certificate.
