The evaporator being a single plate between the water and the refrigerant, in the event of leakage
through one or more plates, the refrigerant will enter the water circuit by pressure difference
(higher pressure on the refrigerant side). As stipulated in regulation EN378, a propane safety
degassing valve is mandatory on the water side. See Section 3.7.Hydraulic connection
Commissioning
Prior to commissioning the chiller, it is essential to have read and understood the instructions contained
in this implementation manual.
Connection of the safety valves must be carried out and checked. The installer must make a
circuit, from the valve collection point, to guide and safely evacuate the R290 to the open air with
renewal, in a free zone devoid of any electrical equipment or heat source. No protection cap must
block the outlet.
Before any tensioning, it is imperative to check the tightness of all electrical connections (at the
terminals, lugs etc.).
Before the first start, a leak test must be performed on the whole chiller with an electronic detection
device for R290 (propane).
Commissioning must be carried out by qualified personnel with the necessary knowledge of the PLC,
Tecumseh regulation (refer to the "Regulation" manual) and the operation of this type of installation.
At the first time, it is imperative to check and determine the settings corresponding to the desired
application. The technician should perform all checks, adjustments, tests necessary for the proper
operation of the chiller. Make sure that all safety devices are regulated, tested and operational. To make
adjustments to operation, it is essential to have a heat load on the evaporator.
At the end of commissioning, an operating report must be produced (different points on refrigerating,
hydraulic, electric circuit) to trace and analyse the proper functioning of the installation.
