Operation manual

Follow the instructions before using this compressor.

Confirm the direction of motor rotation before

startup.

See Section 5.5 for instructions

Caution before startup

To restart compressor after a long period of being inactive,

rotate air end manually with the power off. If it is difficult

to rotate, contact FS CURTIS directly.

Hearing protection required

Turn off power supply before maintenance or service

around electric equipment, such as starter, and motor.

Remove the 2 RED Shipping Brackets that secure

the motor/airend to the base frame before test run

or startup. Contact FSCURTIS or distributor for

assistance if necessary.

Safety

1. Become familiar with this manual and follow the instructions before

operating the compressor.

2. If any malfunctions or trouble has occurred, do not run compressor until problem is

resolved.

3. Make sure the compressor has been disconnected before servicing or changing

parts. Lockout and tagout prior to maintenance.

4. To ensure human safety and protect the facility from damage, an electrical ground is

necessary.

5. Wear proper apparel during operation. Protective clothing should be worn such as

facemask or safety goggles and non slip footwear.

6. Optional Dryer should be connected to separate 120V power source and follow

Lockout/Tagout procedures for inspection or maintenance.

Additional Safety information forAir Compressors

Like all power tools, there is danger associated with operating this equipment. Accidents are

frequently caused by lack of familiarity or failure to pay attention. Use this machine with

extreme caution. If normal safety precautions are overlooked or ignored, serious personal injury

may occur.

The following are some safety suggestions that users should observe:

Caution

-Users that neglect these safety precautions run the risk of serious injury or death.

-Fingers and clothing must be kept away from rotating parts.

-Compressed air from this machine cannot be used for pharmaceutical, food or health

requirements without further treatment.

-Release all pressure from the system prior to maintenance.

-Electric shock could be fatal.

-Grounding of starter and motor is necessary. Choose grounding cable according to

the power range of the compressor.

-Lockout and tagout power supply before working on control panel.

-Lockout and tagout power supply before inspection and maintenance - compressor is

controlled by PID and may start automatically according to the setting.

-Optional Dryer should be connected to separate 120V power source and follow

Lockout/Tagout procedures for inspection or maintenance.

Warning

-Users who neglect the following instructions may damage the compressor.

-Lockout and tagout the compressor if maintenance is needed.

-Lockout and tagout power supply before inspection and maintenance - compressor is

controlled by PID and may start automatically according to the setting.

-Optional Dryer should be connected to separate 120V power source and follow

Lockout/Tagout procedures for inspection or maintenance.

-Relief valve is necessary for air piping larger than 1/2”.

-Do not exceed the rated discharge pressure on nameplate during operation.

-The enclosure should be in place prior to operation

2.0 Receiving and Installation

A. Receiving

1. Check that your shipment matches your order.

2. Check for any damage that may have occurred during shipment.

B. Installation.

In order to ensure proper installation and trouble free operation with minimal maintenance:

1. Select a location where light is adequate enough to operate, maintain, and inspect the

compressor.

2. A clean, low relative humidity and well-ventilated area is best for safe operation.

The ambient temperature should be kept below 104°F (40℃). The air delivery of the

compressor will decrease as the temperature gets higher.

3. Reserve space for maintenance, the distance between the compressor and the wall or

other equipment must be greater than 28 inches (71 cm).

4. There must be at least 3 feet of clearance between top of compressor and any over head

obstructions.

5. To avoid damage to the unit, lift using eyebolts and straps as shown in Figure 2.1

C. Precaution for piping foundation and cooling system

1. Air piping

(1). Install required accessories.

(2). Main piping should have 1˚- 2˚ slope away from compressor to drain the condensate.

(3). Pressure drop of piping must not exceed 5% of discharge pressure. Select larger piping

than required for better efficiency.

(4). Branch line must be located at the top side of main piping to avoid the condensate from

flowing to the equipment.

(5). To prolong service life of pneumatic tools, install an air filter regulator unit on the

outlet.

(6). Do not randomly reduce the size of the main piping. Use the proper reducer if

necessary to reduce pressure losses.

(7). The ideal installation arrangement of air solution is air compressor + air tank + dryer.

The air tank is capable of draining some of the condensate and cooling down the

temperature of compressed air. This will lead to more efficient dryer operation.

(8). If the air requirement is large in a short period of time, install a higher volume air tank

to reduce the frequency of full/off load control.

(9). The ideal main piping is constructed around the factory as a loop which is better for

delivering compressed air from both sides at any point.

2. Foundation

(1). Select a solid and level surface to install the compressor.

(2). There is no need to construct a base for the screw air compressor since the vibration is

relatively small. However, the area must be flat and strong enough to support the

weight of the unit.

3. Cooling system

Install an air-cooled compressor in a well-ventilated area to avoid high temperature

shutdown. If placed in a sealed room, air extracting and removal apparatus is required

and its capacity must be larger than the cooling fan in the compressor.
