systems of the compressor, is in good condition. If damaged, replace it by genuine material
from the manufacturer to prevent the sound pressure level from increasing.

20. Never use caustic solvents which can damage material of the air net e.g. polycarbonate

bowls.

21. The following safety precautions are stressed when handling refrigerant:

1) Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if
required, use breathing protection.

2) Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin

with water. If liquid refrigerant contacts the skin through clothing until, all refrigerant is
flushed away; then seek medical first aid.

22. Protect hands to avoid injury from hot machine parts, e.g. during draining of oil.

Also consult following safety precautions; Safety precautions during
operation and safety precautions during maintenance.

2.0: INSTALLATION

2.1 Compressor Dimensions Drawing:

2.2 Mounting and Space Requirement:

The LPRS series is designed for indoor applications only. Allow at lease three (3) feet

clearance on all sides of the compressor to facilitate maintenance as well as free circulation of
air. Unit should be located in a clear, well-lighted area that will not have an ambient air
temperature below 40 degree F or exceed 105 degree F. Provisions must be made for proper
ventilation so that the temperature of the room will not exceed 105 degree F.

Foundation:

Your LaPlante’s rotary screw compressor does not require a special foundation. However, it is
necessary that the floor is level and the frame adequately supported. Consult the
“Specifications” section of this manual for the compressor weight and dimensions. We do
recommend that the compressor be bolted to the floor.

Room:

- 12 -

Operation manual

The room should be of adequate size to provide full access to the machine for routine
maintenance. It should have ventilation to keep the room as cool as possible. It is
recommended that the air handling system be designed to permit no more than a 10 degree F
rise in room temperature. Operating at elevated temperatures will cause nuisance overload,
temperature shutdowns and reduces oil life. The recommended minimum room air flow is

Approx.1500CFM.

Air Intake:

Air supplied to the compressor should be free of contaminants such as paint spray mist and
vapors, other chemical vapors as well as normally air bone dust and dirt particles.

Inlet air to the unit may vary slightly in temperature without adversely affecting the performance
of the compressor. However, ambient air temperature should be maintained between 32 deg. F
and 104 deg. F to obtain desirable performance.

The air filter supplied with the compressor has an adequate flow capacity for most applications.
In particular dirty locations, clean air may be ducted in from a clean air source or special air
cleaners may be installed. Generally, most adverse conditions may be overcome by regular
servicing of the filter furnished with the unit.

When bringing in outside air into the compressor building for cooling and/or compression, the
air inlet to the compressor building should be located away from contaminants such as engines
exhaust gases, steam and other harmful vapors.

Also, the opening to the building must be protected from rain, snow and other air-borne debris
by cover or hood, as well as being located above the ground/roof to prevent other foreign
matter pick-up. For a typical ducting arrangement refer to (figure 2-1)

Figure 2-1 Typical Ducting Arrangement

Both inlet and outlet ducts must be sized so that they are restriction free. Where ambient
temperatures are below 32 deg. F (Inlet air), entering the compressor’s air temperature can be
raised by controlled re-circulation. This may be accomplished by using adjustable louvers (or
duct dampers) to admit warm air from the outlet duct back into the inlet duct at a controlled rate.

If duct filters are used, the filters must be restriction free. Typical furnace filter material may be
used.

The inlet grids and ventilation fan should be installed in such a way that any recirculation of
cooling air to the compressor is avoided. the maximum air velocity through the grids is 16.6

- 13 -

Operation manual

ft/s .

Inlet containing reactive gases will cause the failure of the lubricant and
compressor.
Insure an air supply that is well clear of any reactive gas source.

Air Supply to Compressor (Cooling and Compression):

The cooling air discharge must be restriction free. Any louvers or ducting must not exceed the
allowed static head shown in the specifications. Above this booster fan will be required.
Consult a local HVAC contractor for recommendations prior to installation. Excessive
restriction to the cooling air discharge will cause the unit to operate at elevated temperatures
that could result in high temperature shutdowns. Ducting of cooling air to the unit is not
generally recommended.

Inadequate airflow will cause the compressor to run hot, can damage the
compressor, and increase the amount of oil carryover.

The room temperature should not raise motor than 10 degree F and the
cooling air discharge must not be restricted.

Electrical:

A qualified electrician in compliance with standards and local codes should do all electrical
wiring. Be sure to investigate the local requirements before installing the compressor.

The power supply should be adequate and free of parasitic loads that will cause an under
voltage condition during the operation of the compressor, otherwise there will be nuisance
electrical shutdowns. Though the unit has a disconnect, we recommend that one be installed
away from the machine and insure the unit is properly grounded.

We recommend the use of time delay fuses in fusible disconnect for isolating the unit. This
disconnect should be located so an operator can disconnect the unit without nearing the unit,
in case of an emergency. We also recommend the use of a lockout/tag out program to help
insure safety during maintenance of the compressor. Per the national Electric Code the time
delay fuses should be sized at 175% if the FLA. Consult the code if you want to use another
style of branch circuit protection.

In all cases, the local, state, and national electrical codes must be strictly
followed.

All control enclosure wiring has been completed at the factory. Connect the wire steps are
as follow:
A. Open the power cabinet door
B. Check that the motor cables and wires are clamped tightly to their terminals.

- 14 -

Operation manual

C. Check the fuses and the setting of the overload.
D. Connect the power supply to the terminals the L1, L2, L3.
E. Connect the earth conductor bolt.

For choice the cable please reference table 3-2 of the electrical specification sheet.

2.3 Guidelines for Compressor Air System:

· The air pressure drop between the compressor and the point of use is not recoverable.

· Pipe Size should be large enough that the pressure drop does not exceed 10% between

the air receiver and the point of use. Generally keep the compressed flow at around 1500 –
2250 feet/minute velocity.

· Arrange the air distribution pipe to avoid the following types off strains:

1. Strains that is due to the dead weight if the pipe itself.

2. Strains that is due to expansion or contraction of the pipe due to temperature.

3. Strains due to internal pressure within the pipe.

· Design inlet and discharge piping for smooth airflow.

· Plan for future emergencies and establish an area of the loop to install a temporary

compressor.

· Consider bypass lines around all items that may require future maintenance.

· Use loop-pipe systems if possible, both around the plant and within wore areas.

· Consider a second receiver at the end of the line or opposite side of the loop.

· Locate runs away from the main header close to the point of application. This limits the

pressure drop through hose.

· Take air off the top of the header to prevent carryover of condensed moisture to tools.

· Slope pipe so that it drains toward a drop let or moisture trap away from the compressor.

2.4 Unpacking and Handling:

Occasionally damage will occur during shipping. Be sure to carefully inspect the unit before
unpacking and after unpacking before you sign the receiver. If any has occurred, document it
with the trucking firm immediately. Contact you LaPlante representative for assistance.

To move your compressor to its installation site, we recommend that you leave the unit on its
shipping skid as long as possible. The forks should be extended the width of the compressor
and padding should be placed between the compressor and the fork truck boom.

If it is necessary to lift the compressor with a crane, we recommend the use of spreader bar
and chains. The spreader bar should be greater than the width of the compressor and padding
placed on the edges to prevent chain damage.

Procedure for Handling Damaged Shipments:

1. The customer, at the receiving point, MUST inspect each shipment for damage.

2. If the shipment is damaged, the customer should so note it on the freight bill.

3. The customer should request an inspector from the freight company to inspect the equipment

- 15 -

Operation manual

immediately. It is best to send a confirming letter with the following information:

a. Freight bill number.
b. Date delivered - shipper's name & address.
c. Description of item(s) damaged.
d. Description of damage (a Polaroid picture if possible).
e. A copy of your invoice for the equipment.

4. After inspection, (before the inspector leaves):
a. Get a copy of the inspection report.
b. Request the unit be shipped back "free astray".
c. Request a credit for the original freight bill.

5. Call the factory and:
a. Get a Return Material Authorization (RMA number).
b. Give a purchase order for repair. The purchase order should refer to the item

and
trucker claim.

6. We will accept the shipment back, repair (under normal conditions) and return it within (7)

seven working days.

7. We will invoice the customer for the repair, which will then become part of your claim. The

invoice must be presented to the trucking claim department along with their claim form.

8. We suggest if the trucker does not pay within 30 days that you call and / or write the ICC

making a formal complaint of poor service. Also advise LaPlante Compressor Ltd. in
writing for follow-up.

If damage can be repaired at the receiving point, follow Procedure 1, steps 1 through
4a. Repair the unit and make out a detailed invoice to the trucker showing labor hours,
labor rate, materials used, and cost of materials.

2.5 Storage

In some cases it may necessary to store the compressor for extended periods of several
months before placing the unit in operation. When this is required do the following:

1. Cover and seal all machine openings to prevent the entrance of water and dirt.

2. Cover all openings in open drip proof motors to prevent the entrance of rodents.

3. If the storage conditions are below freezing, drain off the aftercooler, traps, water-cooled
heat exchangers and relative piping. We do not recommend outside storage.

4. Cover with a waterproof tarpaulin that can easily be removed for in storage maintenance.

5. While in storage, every two to three months rotate the compressor and motor by hand to
prevent flat spots on the bearings that will lead to premature failure.

At the end of the storage period, follow the uncrating and start-up procedures. If the unit has
been stored for more than eighteen months you should contact LaPlante Compressor Ltd.
before commissioning the compressor.

2.6 Installation Drawings (Recommended):

A minimum distance from walls, other machines, etc. should be maintained so that there is
sufficient clearance for maintenance and repair work ( refer to figure 2-2) .

We recommend a minimum duct cross-section of approx. 0.3 square meter. In order to ensure
a good heat dissipation, auxiliary fans should be rated to process approximately 15-20% more
air volume than the total cooling air quantity required by the compressors installed in the
compressed air station.

Operation manual

4.0: CONTROLLER

4.1 Introduction:

In general, the controller has following functions:

l Controlling the compressor
l Protecting the compressor
l Monitoring components subject to service
l Automatic restart after voltage failure

Automatic Control of the Compressor

The controller maintains the net pressure between programmable limits by automatically
loading and unloading the compressor. A number of programmable setting e.g. the
unloading and loading pressures, the minimum stop time and the maximum number of
motor starts are taken into account.

The controller stops the compressor whenever possible to reduce the power consumption
and restarts it automatically when the net pressure decreases.

Protecting the compressor

Shut-down
If the compressor outlet temperature exceeds the programmed shut-down level, the

compressor will be stopped. The compressor will also be stopped in case of overload of
the drive motor.

Shut-down warning
A shut-down warning level is a programmable level below the shut-down level.
If one of the measurements exceeds the programmed shut-down warning level, this will

also be indicated on the display to warn the operator before the shut-down level is reached.

Service warming

If the service timer exceeds a programmed value, this will be indicated on display to warn
the operator to carry out some service action.

Automatic restart after voltage failure

The controller has a built-in function to automatically restart the compressor when the
voltage is restored after voltage failure. This function is deactivated in compressor

leaving the factory. If desired, the function can be activated.
