Controls
Electrical connections may become un-tightened during transport. All electrical connections should be checked
and re-tightened prior to commissioning. All electrical connections shall be made according to the wiring diagrams
provided on the components or in provided documents. Warranty is not valid if electrical components are not
connected properly.
When the unit use a medium (water/refrigerant) with a temperature below than +2°C, The unit controls should be
designed in order to protect the exchanger against freezing. Trane cannot be held responsible for damages coming
from freezing / de-freezing operation.
Electrical motors
Electrical motors are factory-tested and properly run when leaving the factory. Any wiring faults on motors will cause
damage for which Trane cannot be held responsible.
Electric heaters
The warranty does not cover overheating due to wrong use or improper control of electric heaters.
Warranty conditions
Dismounting or changing the units and/or components without Trane approval or assistance will invalidate the
warranty.
The Trane units have been manufactured according to the selections and drawings provided with the order: Trane
cannot be held responsible for eventual non-compliance to original specifications or specific requirements outside
the order.
In order to avoid fan motor overloading, the units shall be started with filters and other components fitted correctly,
the ductwork connected to the units and the access doors closed.
Make sure the units work at design (air flow/pressure) conditions. The sound levels of the units can vary a lot
depending of the fan speed, the filter conditions or the actual duct pressure drops. Also, the given sound levels
can be highly affected by the installation method, the peripheral components, the ductwork and the acoustic
characteristics of the building/room.
The units must be controlled in order to not exceed the max differential pressure drops on plate heat exchangers
indicated in the technical data sheets.
Unit drainage
Drain traps: When the units have more than one drain trap, each drain shall be connected to the drainage system
separately with siphon.
Thermal wheels
The air leakage rate between fresh air and return air streams on thermal wheels and plate heat exchanger can go up
to consistent value, even more than 5%, under normal working conditions. The exact value depends on composition,
fan static pressure and pressurization/under pressurization of each side of the recuperator. In case of critical
application concerning contamination and/or air leakage, to avoid air bypass, the pressures on the fresh air side shall
be higher than on the return air side. The recuperator efficiencies are given for counter flow configuration.
The operation and the efficiency of thermal wheels can be deteriorated when they are stopped for a too long period
of time. The thermal wheels should be regularly inspected.
Large thermal wheels may be provided in several sections due to transport constraints. In this case, they need to be
re-assembled on site by trained people or with Trane Assistance (recommended).
Casing
Structure is designed so that it will not suffer permanent alteration up to a positive pressure and negative pressure
of 2000.
Maximum temperature for the CLCF casing is 50°C. (40°C inside temperature for standard fan motors).
Extreme outdoor condition and/or internal air temperature may cause sweating on profile / Thermal bridge. In case of
extreme internal/outdoor conditions, contact Trane.
