Potable Water Systems - York YAWS018 - 075 Installation Manual

Potable Water Systems cont.
Hot Water Generator Connections
The heat reclaiming hot water generator coil is vented double-
wall copper construction and is suitable for potable water. To
maximize the benefits of the hot water generator a minimum
50-gallon water heater is recommended. For higher demand
applications, use an 80-gallon water heater as shown below or
two 50-gallon water heaters connected in a series. A geo storage
tank should not be used in this application unless it is plumbed
in a series with an electric water heater. The geo storage tank
is equipped with a single 4500 Watt element and will not be
able to provide adequate water heating if used as a standalone
water heater. Electric water heaters are recommended. Make
sure all local electrical and plumbing codes are met for installing
a hot water generator. The unit is not supplied with an internal
circulator. A DPK5 kit will need to be purchased to connect to
the hot water generator. The DPK5 kit is supplied with installation
instructions, circulator, tank adaptor and temperature limit switch.
Be sure to burp (vent) the pump. Open the screw 2 turns only
in the end of the pump motor (if Grundfos
to allow trapped air to be discharged and to ensure the motor
housing has been flooded.
