Clearance Distances; Weight Distribution; Hydraulic Connections - RHOSS TCCE 135 Gebrauchsanweisung

II.3.1

CLEARANCE DISTANCES

IMPORTANT!
The unit should be positioned to comply with the
minimum recommended clearances, bearing in
mind the access to water and electrical
connections.
If an installation does not comply with the specified clearances, it will
lead to poor running of the unit, with a consequent increase in power
consumption and a perceptible reduction in the cooling performance,
due to an increase in condensation pressure. The space over the unit
has to be free from any possible obstacle. If the unit is completely
surrounded by walls, the distances specified are still valid, provided that
at least two adjacent walls are not higher than the unit itself.
If several units are to be installed, the distance between the finned coils
must not be less than 2m., in order to avoid any interference in the
operation of the condensation/ventilation section of individual units.
It is advisable to leave more space than the minimum specified in 5 and
6, to allow for replacement of components, should this become
necessary.

WEIGHT DISTRIBUTION

IMPORTANT!
Correct installation and positioning includes
levelling the appliance on a surface capable of
bearing its weight.
The unit is designed to be installed either at ground level or on the flat
roof of a building. For proper installation see enclosed documents (A4
Weight distribution).
If the unit is to be installed on buildings which should not suffer the
effects of mechanical vibrations, special supporting systems can be
utilised, to insulate the entire unit from the rigid supporting plane.

SECTION II: INSTALLATION AND MAINTENANCE
Alternatively, the problem of transmission of vibrations through the base
can be eliminated by fitting the special rubber anti-vibration mountings
available as accessories (KSA: vibration-damping supports).
The weights of the units are shown in the attached tables (see A4
Weight distribution).
IMPORTANT!
In cases where the transmission of vibrations is a
serious problem, consult a specialist of proven
competence.
II.3.3

HYDRAULIC CONNECTIONS

IMPORTANT!
The layout of the water system and connection of
the system to the unit must be carried out in
conformity with local and national rules in force.
IMPORTANT!
We recommend installing isolating valves that
isolate the unit from the rest of the system. Mesh
filters with a square section (longest side = 0.8
mm), of a suitable size and pressure drop for the
system, must be installed. Clean the filter from time
to time
The units feature 2"G male threaded water connections.
Air vents and on-off valves must be installed on the inlet and outlet
pipes of the unit to isolate the appliance from the rest of the system.
This not only allows the heat exchanger to be emptied but also leaves
enough space for any maintenance work or the removal of the heat
exchanger. A filter must be fitted on the water system return pipe, and
flexible couplings on the water connections have to be installed. Once
the connections to the unit are made, check that none of the pipes leak,
and bleed the air from the system. The following chapters explain the
plumbing connections for the different versions of the unit.
