Transport and storage
JAMA Inverter must be transported and stored vertically.
Assembly
႑ Place JAMA Inverter outdoors on a solid level base that can
take the weight, preferably a concrete foundation. If
concrete slabs are used they must rest on asphalt or
shingle.
႑ The concrete foundation or slabs must be posi-
tioned so that the lower edge of the evaporator is at
the level of the average local snow depth, al-though a
minimum of 300 mm.
႑ The JAMA Inverter should not be positioned next to sensit-
ive walls, for example, next to a bedroom.
႑ Also ensure that the placement does not inconveni-
ence the neighbours.
႑ JAMA Inverter must not be placed so that recirculation of
the outdoor air can occur. This causes lower output and
impaired efficiency.
႑ The evaporator should be sheltered from direct
wind. Place JAMA Inverter protected from wind against
the evaporator.
႑ Large amounts of condensation water as well as
melt water from defrosting can be produced. Con-
densation water must be led off to a drain or similar (see
page 7).
႑ Care must be exercised so that the heat pump is
not scratched during installation.

Do not place JAMA Inverter directly on the lawn or other
non solid surface.
If there is a risk of snow slip from roof, a protective roof or
cover must be erected to protect the heat pump, pipes
and wiring.

2 Delivery and handling

Condensation run off
Condensation water trough
The condensation water trough is used to collect and lead
away condensation water from the heat pump.
NOTE
It is important to the heat pump function that
condensation water is led away and that the
drain for the condensation water run off is not
positioned so that it can cause damage to the
house.
NOTE
Pipe with heating cable for draining the con-
densation water trough are not included.
NOTE
To ensure this function the accessory KVR 10
should be used.
NOTE
The electrical installation and wiring must be
carried out under the supervision of an author-ised
electrician.
NOTE
Self regulating heating cables must not be
connected.
Caution
If none of the recommended alternatives is
used good lead off of condensation water must
be assured.
႑ The condensation water (up to 50 litres/day) collec-
ted in the trough should be routed by pipe to an
appropriate drain, it is recommended that the
shortest outdoor stretch possible is used.
႑ The section of the pipe that can be affected by frost
must be heated by the heating cable to prevent
freezing.
႑ Route the pipe downward fromJAMA Inverter.
႑ The outlet of the condensation water pipe must be
at a depth that is frost free or alternatively indoors
(with reservation for local ordinances and regula-
tions).
႑ Use a water trap for installations where air circula-tion
may occur in the condensation water pipe.
႑ The insulation must be tight against the bottom of
the condensation water trough.
Drain pan heater, control
The drain pan heater is supplied with power when one of
the following conditions is met:
1. Operating mode "Heating" or "Hot water" is activ-
ated.
2. The compressor has been in operation for at least 30
minutes after last start.
3. The ambient temperature is lower than 1 C.
Recommended alternatives Stone
caisson
LEK
FrFrostfritost prt oof depth
If the house has a cellar the stone caisson must be po-
sitioned so that condensation water does not affect the
house. Otherwise the stone caisson can be posi-tioned
directly under the heat pump.
The outlet of the condensation water pipe must be at frost
free depth.

Chapter 2 | Delivery and handling

Drain indoors
Water seal
The condensation water is lead to an indoor drain
(subject to local rules and regulations).
Route the pipe downward from JAMA Inverter.
The condensation water pipe must have a water seal to
prevent air circulation in the pipe.

Installation area
The distance between JAMA Inverter and the house wall
must be at least 150 mm. Clearance in front of JAMA
Inverter should be at least one metre.
