Storage and Transport
3.1 General
Requirements
As a rule, the HPWH is to be stored or transported in its shipping box in upright position and without water
charge. For a transport over short distances, and provided due care is exercised, an inclination angle of up to 45°
is permitted. Both during transport and storage, ambient temperatures of -20 to +60 °C are permissible.
3.1.1 Transport using a forklift (or lift truck)
When transported by a fork lift, the HPWH must remain mounted on the pallet. The lifting rate should be kept to a
minimum. Due to its top-heaviness, the HPWH must be secured against tipping over. To prevent any damage, the
HPWH must be placed on a level surface.
3.1.2 Manual transport
For the manual transport, the wooden pallet can be used for the bottom part. Using ropes or carrying straps
(which can be placed around the jacket of the storage tank and secured to the water tube nipples), a second or
third handling configuration is possible. With this type of handling (applies to the transport by hand truck as well),
care must be taken that the max. permissible inclination angle of 45° is not exceeded (see Figure). If transport
in an inclined position cannot be avoided, the HPWH ("heat pump" switch) should be taken into operation one
hour after it has been moved into final position at the earliest.
Caution! Do not lift the unit by its cover
(the cover is not designed to withstand heavy weights ! The
appliance cover must be relieved from the weight of the unit
during transport by taking appropriate measures or using auxiliary
aids)
4. Installation
4.1 Installation Site
CAUTION!
¾
#
The HPWH must be sited in a dry and freeze-proof room, the room air temperature and/or the air taken in
by the HPCDW must be within a temperature range of 15 °C to 35 °C (required for heat pump operation).
¾
#
In addition, the unit must not be installed in areas where there is an explosion hazard due to gases, vapours
or dust.
¾
#
Adequate thermal insulation of areas adjacent to living spaces is recommended.
¾
#
A condensate drain (with siphon) must be provided.
¾
#
The air drawn in must be not excessively contaminated or heavily laden with dust.
¾
#
The floor surface must have adequate load bearing capability (the estimated HPWH weight is 410 kg when
fully charged!).
For the performance of maintenance and repair work clearances of at least 0.6 m must be maintained all around
the unit. If the HPWH is primarily operated as a hot water unit, rather than a ventilation unit, i.e. without airducts
or airduct elbows (
➠
"free-blowing“ installation), a minimum ceiling height of 2.5 m (see Fig. 4) is required (for
efficient operation). The connection to the HPWH is effected (optionally) by means of insulated airducts (NW 160)
which must not exceed a total length of 10 m.
