Beaten by Biarritz in last year's quarter-finals, Munster will travel to Edgeley Park to open their Pool 1 account in the autumn, after the ERC today confirmed the early fixture lists.
Kidney's charges then take on Castres (home) and Newport-Gwent Dragons (away-and-home) pre-Christmas, before wrapping up their pool campaign in January with a visit to Castres and lastly, a Thomond Park tussle against Sale.
Leinster, also beaten quarter-finalists in 2004/05, kick-off their Pool 5 charge against familiar foes Bath, whom they defeated twice last season (30-11 and 27-23), at Lansdowne Road.
Michael Cheika's lot then travel to Glasgow before taking on Bourgoin in home-and-away ties before the end of the year. January will see Leinster welcome Glasgow back to Dublin, and the men in blue end the pool stages with a trip to Bath's famous Rec ground.
Ulster, meanwhile, should start with a Ravenhill win against Italian Super 10 side Benetton Treviso in October.
Tough fixtures against Biarritz (away) and Saracens (home-and-away) follow before the festive break. Mark McCall's men, who have each year failed to make the quarter-finals since their tournament win back in 1999, then take on Biarritz at Ravenhill, and travel to Treviso for the sixth round over the weekend of January 20-22.
The precise dates and kick-off times for all the Pool matches in the early rounds will be confirmed as soon as possible with the broadcaster partners in the UK, Ireland, France and Italy.
