Figure 56. Partial Heat Recovery Piping Recommendations
Note: In addition to those recommended for field piping, the CGAM unit includes factory installed manual air vent and
water drain valve with partial heat recovery option. See
recovery component locations.
Partial Heat Recovery Freeze Protection
The heat recovery condenser is insulated and a factory-
installed heater is installed and will protect the heat
exchanger from freezing in ambient temperatures down to
-20°F (-29°C).
When the ambient temperature drops to approximately
39°F (3.9°C) the thermostat energizes the heaters.
Note: The inlet and outlet piping should be protected
against freezing by one of the following methods:
•
Install heat tape on all field-installed water piping.
OR
•
Add freeze inhibit fluid to the partial heat recovery
water loop.
