Te Ts1 Trs
Ts1=cold room air inlet temperature.
Te=evaporating temperature. It is related to the
refrigerant pressure on the unit cooler outlet.
Trs=refrigerant superheat temperature, on
suction line near thermostatic valve bulb.
(Trs-Te)=superheat
(Trs-Te) ≤ 0.7 x (Ts1-Te)
Keep the superheat as low as possible to obtain
maximum unit cooler performance.
The thermostatic valve fitted must be correctly
sized for the installation conditions and adjusted
for correct system operation.
6.5 Pressure test
6.6 Drain line
Check all drain lines and driptrays to ensure that no improper material such as, e.g., packaging
material blocks the drain.
In FMS25 models, mount PVC driptray drain.
Tighten by hand only. Close the driptray.
60°
For all models, connect the drain tubing to the
drain connection.
The drain line diameter must be at least the size
of the driptray drain diameter and should be laid
with an adequate slope. For room temperatures
below 0 °C drain line insulation and defrosting
are required.
A syphon must be installed on the drain line,
outside the cold room.
Tighten drain connection by hand only.
