4.32 CEILING MOUNT
HRV systems generate considerable amounts of moisture due to their high Heat
Recovery Efficiency; this moisture must be drained from the system to a suitable
discharge location.
The aircycle 1.3 Ceiling mount drainage connection is
21.5mm
.
Brookvent recommend the use of a 32mm “Waterless Dry Trap” on HRV systems (
as
shown above) to prevent the back flow of air into the HRV unit from the waste discharge
system.
It is imperative that there is a gravitational fall from the unit to the discharge point
ensuring that the water drains from the unit. A minimum fall of
5 Degrees
should be
ensured throughout. Drainage piping/ connections should be insulated if located in cold
roof spaces. NB. Dry trap (Not Incl.) must be fitted with a minimum
10 Degree
fall at
that point with a minimum of 5 degree fall in the condensate pipe thereafter.
Drainage piping/ connections should be insulated if located in cold roof spaces.
DO NOT connect other condensate pipes from the system or other systems BEFORE the
“Waterless Dry Trap”
