Installation Location - Sanden GS3-45HPA-US Installation Manual

Installation location


For the most efficient operation of the heat pump unit, the optimum location is the
warmest side of the property and there should be sufficient space for the air to
circulate through the unit.

The tank unit should be located as close as possible to the most frequently used
hot water outlet such as a bathroom. It may be located either outside or inside. The
heat pump unit must be located outside and as close as practicable to the tank unit
but not further than 50ft (15m) away from the tank.

Ensure sufficient clearance around the heat pump unit to allow air to circulate and
provide adequate space for service maintenance of the unit (Figure 3).

Although the heat pump unit is very quiet, it is preferable to avoid installing it
directly below a bedroom window.

Install the heat pump unit in an area which allows sufficient ventilation. Poor
ventilation may cause the unit to short cycle and this could increase power
consumption by more than 10%.

Do not install the heat pump unit in a confined space without making provision for
intake or exhaust airflow for the unit.

If the heat pump unit is installed facing a wall, exhaust air may stain the wall.
Figure 3: Restrictions on where the heat pump unit can be installed (overhead view)
※１ Unit should have a minimum of 18" or 500mm space above the unit to ensure correct operation
２ Discharge Air blowing against a wall/obstacle in front of the unit may stain the wall/obstacle
３ If the unit is not able to operate with adequate airflow due to obstacles and reduced clearances,
Then heating output will be reduced by approx. 10% and power consumption increased by approx.10%
４ For optimum operation install the unit per the above or in a location with no obstacles
