The cabinet is designed so that the return air can be located on either side of the cabinet, or
from the bottom of the cabinet. Position a filter rack so that the filter is readily accessible. A
filter and filter rack are not included. Sides are marked for a standard 16 x 20 in filter rack.
WARNING - Special care should be taken in the vicinity of the coil to avoid
puncture. Screw into opening flange instead of top of cabinet when fastening the
supply air duct.
Plumbing
Install a ½ in sediment faucet or ball valve for use as a drain/purge valve. The drain valve must
be located downstream of the pump and check valve, and upstream of the isolation valve (if
isolation valve is present). With this arrangement, any air trapped in the system can easily be
flushed out following the instructions in the Start-up & Troubleshooting sections. Isolation
valves are recommended, but not required. Installing isolation valves facilitates easy servicing.
When the space heating loop connections are made to the domestic water connections:
The heating loop connections should be positioned horizontally in a vertical section of
the domestic water line for both inlet and outlet. Refer to the piping schematic for
details.
Connect the heating loop to the domestic water connections as close to the water
heater as possible
Avoid sections of pipe in the heating loop that can trap air where possible. It is usually
impossible to install a system without having at least one part of the system or heating coil able
to trap air. This will not be a problem if the connection to the domestic water lines is made
properly, and purge valves and air eliminator devices are installed.
Following the flushing procedures in the start-up section will ensure that there is no air
in the system after initial set-up.
Follow recommendations supplied by the manufacturer of the heating source being used.
ecosmart includes a flow switch connection where a flow switch can be connected to allow for
domestic water priority. Note: the correct type of flow switch is a normally open (NO) device.
The flow switch closes when domestic water is flowing
