In case of an inspection, the user of this product must keep the pressure vessel book provided by the
manufacturer available, attached to the other safety documents required by NR-13 of Labor Ministry
of Brazil, for as long as the vase is used, until it is disposed of. The final user must follow the
resolutions set forth in NR-13 as to the installation, maintenance, and operation of the pressure vase
(compressed air receiver). The useful life of a pressure vase depends on several factors that do
contribute to determine it. This aspect must be monitored and established by a certified professional,
according to NR-13. Remark: The hydrostatic test carried out during the product manufacturing does
not replace the initial inspection, which must be carried out at the location where the product is
installed, duly followed up by a certified professional, according to NR-13 MTb. Schulz S.A.,
manufacturer of the product, declares that the local legislation and inspection rule upon the above
provided information, and that all prudent, preventive, and wise safety procedures must prevail.

Technical/Distributor or the factory ([email protected]).

Do not carry out any maintenance jobs with the compressor on. Do not remove accessories attached
to the compressor when it’s pressurized. Do not clean or touch the electric components without
unplugging the compressor from the electric network. Not following the orientations may cause
physical and material damage.

Air compression is a heat generating process. The pump unit

and tube

are subject to high

temperatures. Therefore, one must be careful when handling them in order to avoid burns.

The refrigeration air intake on the case and belt cover

and cabinet

must always be clean to prevent the

flywheel and fan from pulling in impurities.

Never use solvents to clean your air compressor.

The use of solvents or paint accumulation may cause explosion risks and irreversible damage to the product
in general. Cleaning products and the environment may not contain solvents.

Always use an electric extension cord according to specifications (see Table 2) which must not be amended. If

these recommendations are not followed, the user may be injured and the compressor electric components
may be damaged, violating the warranty. When necessary, use a longer air hose.

In case of any irregularities with the equipment, stop operating it immediately and look for the nearest Schulz
Authorized Technical/Distributor.

The compressed air would contain damages contaminants to the human, animal, ambient or
nourishing health, among others. The compressed air must be treated with adjusted filters, as
requisite of its application and use.

Grounding Instructions:

This product must be grounded. In the event of an electric
fault, grounding reduces the risk of electric shock by providing
an escape wire for the electric current.

- The item

is supplied for the models MS 3/30, CSA 6,5/30, MSV 6/30 and MSV 6/50 with plug 2P + GR (ground)

see Figure 6. For the models MSV 12/175 and MSV 18/250 without the plug, its must be connected to electrical
source (electrical starter and fusible) or according with the electrical laws for each country where the
compressor will be installed. For the models CSV 15/220, CSV 15/250, CSV 20/220 and CSV 20/250 is
responsibility of the user the installation of the compressor to electrical source, including the electrical starter.

- For the products CSV 15, MSV 18 and CSV 20 is responsibility of the user/owner installs an air control valve

(register) in the connection of exit of the tank (1/2”).

Install the compressor in a covered, well ventilated area, free of dust, gases, toxic gases, humidity or

any other kind of pollution and for model MSV 6/50 - Split, see Figure 20. The maximum ambient temperature
recommended during work is 104°F (40°C).

Avoid place such as: store, store-room, basements, garage and bathroom.

Mount at least 32 inches (800 mm) from any wall or obstacle and with minimum two (2) meters of

height, to allow good ventilation during operation and to make maintenance easier. When cabinet

is used,

the minimum distance should be 4 inches (100 mm).

When connected to the compressed air network, the discharge connection

(1/4") and 1/2" (CSV 15, MSV 18/250 and CSV 20) must be joined by meas of a hose or expansible gaskets so
that the charges, thermal expansion, piping weight, mechanical and thermal shocks or obstructions are not
transmitted to the air tank. Physical damage to the compressed air tank may occur if the above warnings are
not followed. Instruction assembly rectangular filter (see Figure 5).

Model MSV 6/50 - Split is supply of factory with a hose 5/16” x 787” (8mm x 20 m). Other distance, use a

hose of 1/2".

It must be placed on a concrete base, which must be able to bear the equipment weight plus

the liquid (water) when of the hydrostatic test. The set must be level. The compressor models is equipped with
rubber foot (assembled by owner) see Figures 2, 3 and 4 and Figure 1 for model MSV 12/175, place de
compressor on anti-vibration (owner’s responsibility), absorves which, in turn, must be replaced on a concrete
basis. The set must be level and the absorver must be adequate to support the equipment weight and vibration.

Use a little water to assembly the absorver for models MS 3/30, CSA 6,5/30, MSV 6/30 and MSV 6/50,

Figure 3.

Consult a specialized technician to evaluate the electric supply and to select the adequate protection and

input devices.

Follow the technical standards of the country on Low Voltage Electric Installations.
Figure 7, shows a electrical diagram for electric connections with pressure switch and fuse.

The electric input wires must be in accordance to the motor power, voltage and electric energy source

distance. See table 2 for guidance.

Before plugging in the equipment, check if the voltage shown in the input wire tag is the same as the local

voltage.

IMPORTANT

7) INSTALLATION

The incorrect installation of the grounding wive may result in an electric shock. If it is necessary to replace or

repair the cable or the connector, do not lead or join the grounding wire to the neutral wire or other. The green
wire, with or without yellow stripes, is only to the grounding function. In case of doubts regarding the
grounding information or whether the product is properly grounded, make sure you contact a qualified
electrician to verify the connections.
