Precautions before Unit and Piping Installation
1. The unit is limited to indoor installation. Make sure to consult the user about the
specific installation location.
(1) Where possible, discuss and confirm the unit installation method and
piping/wiring work from the building’s design stage.
(2) The unit should not be installed near staircases or evacuation exits.
(3) Check the drainage situation of the location where the unit to be installed,
making sure that the unit will not become covered with water.
2. When installing the unit in a high place, make sure to install the unit at a
location where maintenance work etc. can be carried out, and where handrails
etc. are installed to prevent falling. If work cannot be performed, TLV may
refuse after-sales service.
3. Install and operate the unit in a well-ventilated location with an ambient
temperature up to 50
C. When the temperature exceeds 50
C, measures
such as ventilation should be considered.
4. In areas where salt damage is likely (areas close to the ocean that receive a
sea breeze), the unit should be installed in a downwind area of the building.
When it is necessary to install the unit facing the coast, take measures to
protect the unit from the sea breeze, such as installing a windbreak screen, etc.
5. Installation and maintenance space
(1) Before installing the unit, determine the installation position and then set
the anchor bolts. (M12 bolts with an embedded length of 10 cm or more
are recommended.)Make sure that the
unit is secured with anchor bolts before
installing the piping to prevent the unit
from falling.
(2) Maintenance space
In order to inspect and repair
components in the unit, set up the unit
with the maintenance space in
accordance with the diagram shown
below to keep the sufficient distance
from the surrounding walls and
components. If there is insufficient
maintenance space, maintenance work may be refused.
(3) Strength of installation floor
The weight of the unit (when empty) is approx. 450 kg. (Weight varies with
optional components.)
If the floor cannot support the weight of the unit when installed,
reinforcement work should be carried out before installation.
6. Precautions before installing piping:
Make sure to flush the steam piping and water supply piping before connecting
the unit. Flushing the piping is different from the initial blowdown, which is
carried out to discharge condensate before operation. Flushing is performed to
remove the residual sealing material, metal chips, sand or scale in the piping.
Therefore, it is necessary to powerfully flush the piping from as large an
opening as possible.
