DAIKIN MULTI-SPLIT
Up to five rooms on one outdoor unit
The Daikin 5MXM90A9 is the largest multi-split outdoor unit we stock, for up to five indoor units: a whole house, a guest house or a set of offices on one condenser.
It is the only one of the three that takes the 7.1 kW FTXM71A, so a large open-plan living area can share the system with the bedrooms.
It runs on R32 and is rated up to A+++ in cooling and A++ in heating, depending on the indoor units connected.
INDOOR UNITS
Choose an indoor unit for each room
Each room gets its own Perfera wall unit, sized to that room: the FTXM25A or FTXM35A for bedrooms, the FTXM50A, FTXM60A or FTXM71A for living areas.
The 5MXM90A9 takes indoor units from 1.5 to 7.1 kW, and delivers up to 9.0 kW of cooling in total, shared between the rooms in use. We check the combination against Daikin’s tables before you order.
Every indoor unit has its own controls and built-in Wi-Fi, so rooms are switched on and set separately. All units on one outdoor unit run in the same mode: one room cannot heat while another cools.
MADE FOR SOUTH AFRICAN POWER
One condenser outside, Daikin South Africa stock
One outdoor unit instead of one per room means less wall space taken up outside, fewer units to hide, and less outdoor noise than several condensers running together.
This unit is supplied through Daikin South Africa for a 220–240 V single-phase supply, so the local Daikin warranty applies and parts come through Daikin’s South African network. Auto-restart brings the system back to its previous settings when the power returns after load-shedding.
A multi-split system has to be designed and installed by a qualified installer. Our installers cover the major South African cities and quote separately; send us the room sizes and we will match the indoor units to the outdoor unit.

Figures from Daikin’s published data for the 5MXM90A9. Capacity in use depends on the indoor units connected and how many run at once.
How the 5MXM90A9 sits against the alternatives
For three or four rooms, the 3MXM68A9 or 4MXM80A9 is smaller and costs less.
Five rooms on one outdoor unit share 9.0 kW between them. If most rooms will run at full output at the same time, for example in a guest house on a hot afternoon, two smaller systems or a mix of multi and single splits may cool better.
