Normally  the  fresh  air  system  is  designed  to  deliver 

air  across  the  pool  room  windows  as  illustrated  in 

Sample duct Layout #1 and #2.
The  designer  and  installer  should  be  aware  of  local 

codes  that  may  require  smoke  detectors  and/or 

firestats  in  the  HVAC  or  HRV  ductwork.  A  supply 

voltage interrupt may be  required  to  shut  the  system 

down  when  triggered  by  smoke,  flame  or  a  central 

fore alarm. Check with your local building authority.
Supply  air  grilles  may  be  ceiling  or  high  wall 

mounted. Avoid locating incoming fresh air grilles that 

could  cause  a  direct  draft  on  the  occupants  as  the 

incoming  air  may  be  below  room  temperature.  A 

reheat  duct  heater  can  be  installed  to  improve 

occupant comfort.
The  use  of  balancing  dampers  or  adjustable  grilles 

to balance the flow rates into various rooms is 

recommended.

Handler/Furnace

The  fresh  air  supply  ductwork  from  the  HRV  may 

be directly  connected  to  the  furnace  return  air  duct 

when  a  dedicated  forced  air  system  is  present  for 

the  pool  room. Check the air flow balance of the HRV 

with  the  air  handler blower  both  "ON"  and  "OFF"  to 

determine  that  it  does  not imbalance  the  HRV  more 

than  10%.  Also,  it  is  advisable  to  include  a  short 

length  of  flex  duct  or  other  non-metallic connector in 

this  hard  ducted  line  in  order  to  keep  the  HRV 

acoustically  isolated  and  separately  grounded 

(electrically) from  the  air  handler.  This  will  avoid  a 

possible  shock  hazard  to  service  people  if  a  short  to 

ground develops in one of the devices.

Grilles

The  stale  air  return  system  is  used  to  draw  air  from 

the points  in  the  building  where  the  highest  humidity 

levels  exist.  Balancing  dampers  and/or  adjustable 

grilles  are recommended  on  all  return  air  lines  which 

are  used  during  installation  to  help  balance  the 

“draw” from different areas of the pool room.
Alternately,  the  stale  air  may  be  drawn  directly  from 

the  return  air  duct  in  situations  where  a  dedicated 

pool room air handler or forced air furnace is present. 

The  air  handler  or  furnace  blower  motor  must 

constantly  operate  when  this system is used.
The exhaust takeoff connection must be at least a 3 ft 

(1  m) from  a  directly  connected  HRV  supply  duct  if 

both  are  connected  to  the  same  duct  run.  Static 

pressure  of  the  air handlers  return  system  should  be 

noted  and  compensated for  if,  it  is  apparent  that  the 

static  pressure  of  the  return  in  the  air  handler  will 

exceed 0.1 to 0.15” W.C.

A  damper  located  just  prior  to  the  HRV  is  required 

to balance  the  stale  air  exhausted  with  the  fresh  air 

supply entering the building.
Return  air  suction  points  should  be  located  on  the 

opposite side of the room from the fresh air inlet. The 

inlets  may  be  located  in  the  ceiling  or  high  on  the 

walls  and  fitted  with inlet grilles.

The  use  of  balancing  dampers  or  adjustable  grilles 

as  supply  air  diffusers  and  air  exhaust 

covers  are  recommended.  TECHGRILLES™  are
