5. Installation
5.1 General - Heat Pump
5.2 Acoustic emissions
5.3 General - HydroBox
The Heat Pump outdoor unit must be installed on a permanently even,
smooth and horizontal surface (concrete slab). The base should be sized so
the entire outdoor unit is directly supported. The recommended minimum
concrete slab dimensions are 42" long x 32" wide x 6" deep (107 x 32
x 15.25 cm) for mounting hardware clearances. To prevent small animals
from entering the inside of the device, the connection holes in the base
plate should be sealed where necessary.
The outdoor unit is designed for installation close to walls on even ground,
and must always be fixed in place at the installation site (see dimension
drawing, Section 12). The heat pump profile is tall and slender, so it must
be attached permanently to the base for safety reasons. The responsibility
for the heat pump installation lies with the specialist system construction
company. During the installation, local requirements such as building
regulations, siesmic considerations, the static load of the building, and wind
exposure must be accounted for.
If the unit will see a condition where snow levels exceed 15 inches (.5
meters) it is recommended that a snow stand be used to elevate the heat
pump. The snow stand must be permanently attached to the base and the
heat pump secured to the stand for safety reasons.
If there is risk of snow or ice falling from a roof, a protective roof or cover
must be constructed to protect the heat pump, pipes, and wiring.
It must be possible to carry out maintenance work without hindrance. This is
ensured if the clearances displayed below are maintained.
The heat pump operates silently due to efficient sound insulation. Internal
insulation measures should be carried out to prevent vibrations from being
transmitted to the foundation or to the heating system.
The placement of the unit must be indoors. The HydroBox is not designed
for outdoor or wet environments. It is recommended that the unit be placed
near where the interconnected piping to the outdoor unit enters the building
to keep the piping distance to a minimum. A maximum of 100
feet of 1" pipe
can be used between the indoor and outdoor unit. For longer distances 1
1/4" pipe can be used. However, a resistance head calculation should be
performed based on the supplied Taco 0034e circulating pump to maintain
the target 8gpm flow rate with the chosen pipe size and pipe.
All electrical connections can be accessed by removing the left side panel
of the HydroBox. Although all panels can be removed, the HydroBox was
designed to be able to access all serviceable components and access all
wiring connections by just removing the side panels.
It must be possible to carry out maintenance work without hindrance. This
is ensured if the clearance displayed below is maintained.
The specified dimensions are valid for single unit installation only. (See Fig.
6)
If multiple outdoor units are set up next to each other, the required minimum
distance at the side adds up. Ensure that the cold expelled air is not sucked
in again.
Note:
The cold air is blown out downwards at the side of the heat pump
and can result in black ice on paths and platforms.

Air Flow
Note:
Do not restrict or block the area around the intake or the air outlet
area.
Note:
Observe all local building regulations!
Note:
The physical impacts must be observed for installation close to
walls. No windows or doors should be present in the area surrounding
the air outlet of the fan.
Note:
In cases of installation close to walls, there may be more sediment
in the intake and air outlet area due to the air flow. The colder outside air
outlet should discharge in such a way as to not increase the heat losses
in heated neighboring rooms.
Note:
Installation in a hollow or in an inner courtyard is not permitted
because cooled air collects at ground level and is drawn in again by the
heat pump during extended periods of operation.
Note:
Do not locate where the air intake is near vented appliances (e.g.
driers, furnaces, fireplaces), moisture producing equipment, vehicle
exhaust, subject to direct salty atmospheres, where metal, powder like
substances or chemicals are in the air that could effect the unit (include
livestock breading areas and hot springs).
