Fixing Bracket
Note:
•Fixing Bracket height will be critical in kitchen cupboard.
•There should be no movement once correctly located and the lters should be accessible
from easily removing the panels on the front of the unit. (See Section 4.1.8, and 4.2.0,
Homeowner Guide).

andhasfourxingpointslocatedatequalintervals.Itisrecommendedthatsixscrewsperbracketareused
tosecuretheunit.Screwsandxingsarenotsupplied.
WARNING: Ensure that the ceiling board can support 20kg (Vireo HR155CM)
or reinforcement may be required.
2.4.6 Proceedtoalignandsecuretherstceilingbrackettakingintoaccounttheavailableceilingspacetomount
theunit.Locatesecondbracketposition(See Figure 1) andlooselytfourscrewswithineachslotattheinner

2.6 Condensate Drain
2.6.1 ItisimportantthatanycondensateMUSTbedrainedaway.
•TheVireoHR155WM/HR185WMunitisprovidedwithacondensatedrainlocatedatthebaseofthe
unitunderneath(See Figures 6-10).
•TheVireoHR155CMunitisprovidedwithacondensatedrainlocatedatthesideoftheunit
(See Figures 11-13) andcanberotatedforeaseofconnection.
  Thedrainplugallowsacondensatedrainhose(21.5mmdiameter)tobepushconnectedandsolvent
welded/sealed.Pleaseensureawatertightsealisachieved.
2.6.2 Thedrainmusthaveacontinuousminimumfallof6mmper1mrunandcaneitherbechasedintothewallor
rundownwardsfromtheunitintothenearestwastewaternetwork.Ensurethatstepsaretakentominimise
theriskofmechanicaldamagetothedrainagepipework.
IMPORTANT NOTE: The condensate drain must incorporate a U bend to
create an air block and avoid leakage of smells back into the unit. If the unit
is installed within a loft space, please ensure that the condensate drain is
insulated to prevent against freezing.
2.6.3 Insomeinstances,acondensateconnectingpointwillalreadybeprovidedaspartofthebuildingdesign.
Thepositionofthispoint,relativetowheretheunitistobeinstalledshouldbecheckedforanyconnection
misalignmentandanynecessaryadjustmentmadebeforeproceedinganyfurther.
