RECOMMENDATIONS
For a good functioning of refrigeration circuit,
refrigeration hoses must be clean and dry.
Hoses must be stocked in a dry area, with
less variation in temperature as possible and
sheltered from moisture.
The two ends MUST ABSOLUTELY been
blocked with tight caps to avoid any
internal damages or condensation until their
connection into the circuit.
To fit hoses and electrical harnesses, use as much as
possible RSGU clamps.
To protect hoses and electrical harnesses, use adequate
rubber funnels to avoid cutting with metallic corners.
Installation Hoses Stocking recommendations
Page 24
Operation & Service Manual
Carrier Transicold Europe 31/03/07 Viento - Installation/Rev- #24/54
Right installation
Wrong installation
Do not twist or curve the hose.
Keep enough length to avoid length variation when the
pipes are under pressure.
Pipes length can vary between -2% to +4%.
Using elbows and fittings make easier installations,
assist accessibility and increase hoses/pipes life.
Always insure that minimum radius is respected. Provide
a radius as big as possible to avoid constriction.

The Thermo Expansion valve is a precision device designed
to meter the flow of refrigerant into an evaporator in exact
proportion to the rate of evaporation of the refrigerant in the
evaporator.
The Thermo Expansion valve can control the refrigerant gas
leaving the evaporator at a pre-determined superheat.
The superheat is the temperature difference between T1
(Temperature measured at remote bulb location) and P2
(Evaporation temperature of the last liquid drop).
T1 : Temperature at remote bulb location
P2 : Evaporator outlet pressure
