Conditions Of Use; Special Versions - FPZ SCL R20-MD MOR IE2 Instructions

10.1 CONDITIONS OF USE

Non-compliance with the unit's intended use can cause serious accidents.
• This manual:
MUST be read carefully and understood before carrying out any operations on the unit;
MUST be strictly complied with;
MUST always be at hand in the place where the unit is used.
• Installation must only be carried out by qualified personnel.
The maximum pressure differentials given in the "SPECIFICATIONS" refer to the following operating conditions:

as a blower:
gas intake temperature 20°C (+68°F) and atmospheric pressure 1013 mbar (abs.) (29.92 In Hg ) measured at the inlet port

as an exhauster:
gas intake temperature 20°C (+68°F) measured at the inlet port and atmospheric backpressure 1013 mbar (abs.) (29.92 In
Hg).
The ambient temperature, and the conveyed gas intake temperature, is
permissible inside the range -15°C (+5°F) ÷ +40°C (+104°F) with the
following provisions;
•
for ambient temperature +30°C (+86°F) reduce the maximum
pressure differentials given in the "SPECIFICATIONS" by 5%;
•
for ambient temperature +40°C (+104°F) reduce the
maximum pressure
"SPECIFICATIONS" by 10%.
The graph to be used to reduce the maximum pressure differentials in
case of ambient temperature between +21°C and +40°C (or between
+70°F and +104°F) is given opposite
The maximum height at which the unit can be installed is 1000m a.s.l.; if higher, contact FPZ S.p.A. After-Sales Service.
In case of suction in the place or on the system, protect the intake pipe using a suitable filter with maximum filtration degree 20 µm / 25
µm. For the use of filters with different filtration degree, ask FPZ. Check compliance with the maximum pressure / vacuum data given in
the "SPECIFICATIONS".
To ensure machine operation within the maximum pressure differentials indicated in the "SPECIFICATIONS",
ATTENTION !
it is advisable to use a device for limiting the vacuum / pressure rather than throttling the suction or delivery.
ATTENTION !
If installation is outdoors, protect the unit from the sun.

10.2 SPECIAL VERSIONS

FPZ side channel blowers/exhausters can be manufactured in special or custom versions; the instructions given in this manual still
apply to some of them.
The special versions manufactured, and for which that given above applies, are:
•
TMS version
Machines that ensure mechanical seal between the parts that convey air or fluids, minimising leakage.
•
Special electric motors
On request, blowers/exhausters can be manufactured with motors having one or more of the following characteristics:
Special voltages
-
Higher levels of protection against solid bodies and/or liquids (standard IP55)
-
Higher insulation classes (standard Class F)
-
Protection such as heaters, PTC, PT100 (standard PTO)
-
Further customisation must be requested and agreed when ordering, after a feasibility appraisal by the Technical Department.
ATTENTION !
For maintenance of special version machines, contact FPZ.
