Insulating
In the winter, the unit will be bringing in cold air, passing it through the heat pump, and then
exhausting EVEN COLDER air. In the summer, the CERV will be bringing in hot air, passing through the
heat pump, and exhausting EVEN HOTTER air. It is therefore extremely important that the components
of the system are properly insulated, as to prevent any condensation on the ducting.
Ducts
All ducts except for the RETURN (from inside)
must be insulated. It is recommended to use a
minimum of R4.0 insulation for supply to the inside and R8.0 on the ducts to and from the outside. In
colder climates, it may be necessary to add additional insulation if it appears that the ducts may be
showing signs of sweating.
Water Drain
1. Water drain must be lower than the drain outlet from the CERV2 unit. If not, a condensate pump must
be used.
2. The CERV has an internal water trap for its condensate drain, and therefore no external water trap is
needed. If an external trap is added the CERV side should be open to atmosphere.
