We strongly recommend installing a pressure relief valve on the
hydraulic circuit (standard supply on version ST). In the event of
serious system breakdown or emergency (e.g. fire), the system will
be depressurised via the relief valve thus forestalling possible pipe
bursts. Always connect the relief valve outlet to a pipe of diameter
no smaller than the valve opening, and route it to a location in which
persons are protected from the jet of expelled water.
6.5 WATER FLOW SWITCH INSTALLATION INSTRUCTIONS
- Clean the pipeline system into which the flow switch is to be fitted and remove any magnetic particles, such as
welding residues. To prevent turbulent flow there must be straight pipework, equal to 5 times the diameter of
the pipe, either side of the flow switch.
- Connect the “T” shaped metallic manifold (on which the flow switch is mounted) into the evaporator male
threaded water outlet labelled with:
To avoid leakage, seal the connection with teflon. The flow switch must be installed on the evaporator outlet. On
units with more than one evaporator, the flow switch will be assembled on one evaporator only.
Make the electrical
connections on the
unit’s terminal board
Caution: When making hydraulic connections never use naked flames
close to or inside the unit.
