heat exchangers and are cased in our heavy duty galvanized
and powder coated heat pump unit casings
✓For ease of installation all Ambient variable speed air to water
heat pumps are fully commissioned and quality tested prior to
dispatch
✓They come equipped with hydronic circulation pump expansion
tank pressure relief valve, auto fill kit and fill point
(Hot water models have hot water circulation pump fitted)
✓Ambient on-board controls are standard from factory and are
pre-set ready for use
✓1.5metre buffer tank or supply water temperature sensors are
supplied with units.
(1.5metre hot water tank temperature sensors are supplied with
hot water models)

Heat Pump Location
And Mounting
✓It is important that the Ambient Variable Speed Air
Source Heat Pump is installed so that the outside
ambient air is not recirculated through the outdoor coil
✓Ambient Variable Speed Air Source Heat Pumps are
vertical discharge air flow, meaning fresh air needs to
be available to enter the rear of the heat pump unit
and used air needs to be able to discharge into the
atmosphere
✓AusGeothermal recommend
Ambient Variable Speed Air Source Heat Pumps should
be installed and mounted on a level concrete slab
using rubber mounting blocks and anchor bolts
✓Electrical isolator and pipe work to be easily accessible
for service
✓Electrical and plumbing works to be installed by
licenced and trained technicians only
Important
Failing to comply with above recommendations will
result in Product Warranty becoming void immediately
