Single HPWH Setup

Location

The Heat Pump Water Heater (HPWH) should:

• Be located no further than 66ft (20m) from the tank, and no more than 23ft (7m) above it. Additionally, minimizing pipe length to the tank/pod maximizes efficiency
• Maximum 6 bends, use long-radius elbows, not “street Ls”
• Be installed outside, with adequate ventilation (see Required Unit Clearances)
• Be installed in such a way where water can drain without damaging the heat pump

Note

The HPWH operates most efficiently when located on the East or South side of the property, unless temperatures routinely reach above 100F during the summer.

The heat pump can be installed either on a:

• Preferably a pad or other firm base, or
• On wall-mounted brackets.

Caution

WARNING: While the HPWH is rated max 37dB, noise due to unit vibration may be a nuisance when wall-mounted.

WARNING: If ground-mounted, mount it on risers or pump-ups, to enable access to the drain valve under the unit.

Required Unit Clearances

Source: Source: SANCO2 GS4 Installation Manual

Allow 4” of clearance below the heat pump for the drain plug.

Caution

WARNING: Failure to allow proper clearances and ventilation can negatively impact system performance. Additionally, be cognizant of environmental conditions such as vents or other mechanical equipment when selecting the location.

Installation Example and Additional Dimensions

Caution

Spring isolators (example) and vibration isolator pads (example) should be used if the CO2-HPWH is being mounted on a wall connected to the home.

Powering the HPWH

Caution

 WARNING: Installation instructions in this manual are not meant to encompass 100% of CO2-HPWH installation guidelines and requirements. Refer to the manufacturer for complete instructions.
