Compress 3000 DW FOO
16 | Installation instructions
In New Zealand, the installation must comply with Clause G12
of the New Zealand Building Code.
All packaging materials must be removed from the water heater
prior to its installation.
Required clearances
There must be a 60 cm vertical clearance, a 40 cm minimum
clearance in front of the inlet/outlet grilles and 5 cm clearance
from the back of the appliance (where the drain is) to any
object (
Fig. 7). This will ensure a proper air flow through the
appliance and facilitate the service any time is needed.
Appliance orientation
In case of possible direct exposure to strong wind:
▶ Face the air outlet to the most protected area.
The direct incidence of strong wind in the outlet grille during
long periods may affect the performance of the heat pump
increasing the heating times and the frequency of defrost
cycles. The use of the noise reduction mode is not
recommended in case of moderate or strong wind.
Condensation drain
The unit has a condensate drain, therefore a drain must be
available in close proximity to the unit. The drain must be no
higher than 90 cm above the ground. Discharge point must
comply with AS/NZS 3500.4.
If no drain is available, then a common condensate pump with
a capacity no less than 4 liters/day must be purchased from a
local builder and supply store and installed.
4.3
Secure the appliance
▶ Adjust the height of the adjustable feet to correctly align
the appliance at the installation location.
4.4
Water piping
4.4.1 Inlet - Outlet connections
Installation of the water inlet or outlet pipes: The water inlet and
outlet thread are ¾ BSP (internal thread). Pipes must be heat-
resistant, durable, and UV resistant (when doing outdoor
installation).
Installation of the pipe for PTR valve: The specification of the
valve connecting thread is ½ BSP (internal thread).
All pipe work should be insulated with proper insulating
material (weatherproof and UV resistant if exposed) to
optimize energy efficiency. Water piping sizing should be
performed in accordance with AS/NZS 3500.4.

Typical installation
To ensure faultless operation, the unit must
be installed vertically, with a tilt no more than
1°, preferable in the direction of the
condensate drain in order to favor the
condensates drainage.
WARNING:
Damage to external tank casing!
▶ Do not tilt more than 20° without
packaging.
WARNING:
All plumbing work must be carried out by a
qualified professional and in accordance
with the Plumbing Standard AS/NZS
3500.4 and local authority requirements.
WARNING:
Care should be taken not to touch the pipe
work as it may be hot.
CAUTION:
The temperature and pressure-relive valve
must be installed according to local code.
Not doing so will cause damage to the
appliance and damage to other property.
