Introduction

When used and controlled properly, geothermal heat pumps can save hundreds of dollars in heating and cooling

costs per year. Northern Heat Pump NorthStar Series geothermal heat pumps are designed to provide maximum

efficiency, comfort, and reliability. Solid and simple electric controls allow for low maintenance and built in

safety protection.

This is a prewired package system with the necessary controls for various forced air heating applications. The

EZGEO controller has a 4-position mode switch which allows various combinations of dual heat, AUX EL strip

heat, load control, etc. See the attached HC112 helps – EZGEO Controller.

The EZGEO controller is loaded with options and features you won’t find on other ground source heat pump

controls. The utility load control in the EZGEO system properly manages the cold weather heating mode and

properly controls the air conditioning mode during summer load interrupt. The blower control is designed to

allow the blower motor to operate continuously during cooling peak load interrupts.

Moving and Storage

Units should be stored in original packaging in a clean dry area. Store and move units in normal upright

position. Do not stack units.

Initial Inspection

Be certain to inspect all cartons and crates as units are received before signing the freight bill. Verify that all

items received have no physical damage. Report any damages or shortages on the freight bill. The purchaser is

responsible for filing the necessary claims with the carrier. Concealed or hidden damages not discovered until

removing packaging must be reported to the carrier within 15 days of receipt.

Unit Location and Mounting

Locate the unit in an indoor area where the ambient temperature will remain above 45°F [8°C]. Northern Heat

Pump provides 3 removable panels for ease of servicing; front (2), right and left bottom. This unit is zero

clearance rated; however, allow enough room to remove panels for service and maintenance. We suggest setting

the unit on a sound vibration pad, see accessories price sheet, R-PAD-2735-1-**. Water supply should not be

hard plumbed directly with copper pipe as this could transfer any vibration to living space.

Please read and understand conditions associated with proper installation, unauthorized changes, and POWER ON

procedures.

Warranty Statement
