 Standard Warranty

— 10 Year All Parts Limited Warranty
— 10 Year Labor Limited Warranty

 Domestic Hot Water Heat Recovery Package (Desuperheater):

— Utilizes the compressor's superheated discharge gas

to preheat domestic hot water, reducing the amount of
electricity or fossil fuels otherwise used for hot water.

 Cupro-nickel Coils:

— Cupro-Nickel coils are recommended for applications

where the water is of lower quality. Only coils are
cupro-nickel. All fi ttings and straight lengths of pipe will
be copper.

Field Installed Accessories

 Thermostats:

— Bosch thermostats are fully customized to meet

your individual needs. Bosch offers communicating
thermostats that can display alert messages without
having to go to the unit.

— Passive dehumidification can be achieved via ECM fan

controls paired with optional Bosch thermostat with
humidity control

 Internally Mounted Electric Heat Kits:

— A field installed option for back up heat. Available

in 5, 10, 15, or 20 kW depending on the size of the
geothermal heat pump.

 Stainless Steel Hose Kits:

— Available in various lengths and diameters depending

on the need for your application.

 SmartStart Assist Kit:

— An option which provides a means of reducing inrush

currents at compressor startup. Light flickering is
eliminated, and a smooth start is achieved.

 Horizontal Discharge Air Conversion Kit:

— The horizontal conversion kit allows end blow to

straight through conversion of discharge air, as the
straight through configuration for horizontal is no
longer available.

 Pump/Valve Relay Kit:

— This relay is used to energize a supply pump or

solenoid valve when there is a call for compressor
operation. This relay can be used to switch either
high or low voltage power.

 Externally Mounted Duct Heater Kits
