In order to improve serviceability of our products, the check valve is included with our manual kit for field installation between the air-handler and hot water source.

The check valve should be installed in a vertical run of pipe with the flow of water in an upward direction.

This will allow for ease of service to remove any installation debris or service required due to extended hard water conditions.

Note: Take care during soldering to avoid debris or solder from lodging in the check valve.

An arrow on the check valve indicates its correct orientation and must match the direction of water flow.

Note: It is critical to follow the piping configuration shown. Maintain a minimum distance of 12” above the CAF/AH. This will minimize thermal siphoning in the combo system.

*It should be noted that problems have been observed when using the side tappings on certain water heaters; therefore, it is strongly recommended to use the top water tappings as indicated in Figure 1 to minimize thermal siphoning and related issues.
