6. Never install the compressor outside.
7. For 3 and 5 HP single phase models it is recommended that additional tank volume be added. 3 HP single-phase models need a minimum of 30 gallons of air capacity to limit the number of starts-per-hour to 14 maximum. 5 HP single- phase models need a minimum of 60 gallons of air capacity to limit the number of starts-per-hour to 10 maximum.
VENTILATION

If the scroll compressor is located in a totally enclosed room, an exhaust fan with access to outside air must be installed.
Never restrict the cooling fan exhaust air.
Vent the exhaust air outside to prevent the compressor from operating at high temperatures and shutting down.
Never locate the compressor where hot exhaust air from other heat-generating units may be pulled into the unit.

WIRING
All electrical connections must be performed by a qualified electrician. Installations must be in accordance with local and national electrical codes.

Make sure the power source is the same voltage as the unit’s required voltage
Use solderless terminals to connect the electric power source.
Remove the two left panels.
Pull the electric cable through the electric source inlet and connect to the primary side of the contact blocks.
Since the loosening of wires is possible in shipment, tighten all wire terminals prior to starting the unit.

PIPING
General Guidelines

Make sure the piping is lined up without being strained or twisted when assembling the piping for the scroll compressor.
Appropriate expansion loops or bends should be installed at the compressor to avoid stresses caused by changes in hot and cold conditions.
Piping supports should be anchored separately from the compressor to reduce noise and vibration.
Never use any piping smaller than the compressor connection.
Use a flexible hose to connect the outlet of the compressor to the piping so that the vibration of the compressor does not transfer to the piping.

Remote Intake Piping
Powerex Compressor Systems with pipe thread connectors on the intake filters are intended for installation with remote air intake. Piping for the remote intake system must be installed at the final operating site.
Under some conditions, the intake piping may facilitate the condensation of humidity in the intake air stream into liquid water.
NOTICE
The intake filters supplied by Powerex will not stop the ingestion of liquid water by the pumps. Liquid water going into the pumps will damage the pumps and void the warranty. Always install drip legs with sufficient capacity to capture liquid water in the intake piping before the air filters. Drip legs must be sized with low enough air velocity to make sure they are effective at capturing liquid water in the intake air and must be maintained (drained) at frequent intervals to make sure they remain effective.
SAFETY VALVES
Tank-mounted compressors are shipped from the factory with safety valves installed in the air receiver manifold. The flow capacity of the safety valve is equal to or greater than the capacity of the compressor.

The pressure setting of the safety valve must be equal to or less than the maximum working pressure of the air receiver.
Safety valves should be placed ahead of any possible blockage point in the system, i.e. shutoff valve.
Avoid connecting the safety valve with any tubing or piping. 4. Manually operate the safety valve every six months to avoid sticking or freezing.

Operation

BEFORE START-UP

Make sure all safety warnings, labels, and instructions have been read and understood before continuing.
Remove any shipping materials, brackets, etc.
Confirm that the electric power source and ground have been firmly connected.
Check the belts for tightness.
Be sure all pressure connections are tight.
Check to be certain all safety relief valves, etc., are correctly installed.
Securely mount all panels and guards.
Check that all fuses, circuit breakers, etc., are the proper size.
Make sure the inlet filter is properly installed.
Confirm that the drain valve is closed.

START-UP AND OPERATION

Visually check the rotation of the compressor pump. The rotation should be counterclockwise if viewing the compressor from the belt side. If the rotation is incorrect, have a qualified electrician correct the supply wiring.
Follow all the procedures under”Before start-up” before attempting the operation of the compressor.
Make sure the compressor switch is in the OFF position.
Switch the electric source breaker on.
Open the 3/8 inch discharge valve completely.
Turn the compressor switch to the ON position and check that the compressor operates without excessive vibration, unusual noises, or leaks.
Close the discharge valve completely.
If the pressure does not rise on a three-phase unit, turn the unit off. Have a qualified electrician switch the breaker OFF and exchange the L1 and L2 connections (two out of three phases of electric source) on the control panel
Check the discharge pressure. Also, make sure the air pressure rises to the designated pressure setting by checking the discharge pressure gauge.
Check the operation of the pressure switch by opening the outlet valve and confirming the compressor starts at approximately 95 psi for low-pressure units and 115 PSIG or high-pressure units.

DAILY OPERATION

Stop the compressor by turning the switch to the OFF position.
NOTE: If the compressor rotates in reverse for more than five seconds, the check valve needs to be cleaned or replaced.
Switch the breaker OFF if the compressor is not to be used for a long period of time.

STOPPING THE COMPRESSOR DURING NORMAL OPERATION

Close the discharge valve.
Allow the air pressure to build and the compressor to stop.
Turn the compressor off by turning the switch to the OFF position.

BELT ADJUSTMENT PROCEDURE

Remove the top panel by removing the two slotted 1/4-20 screws on the rear of the enclosure.
Loosen the four (4) motor slide bolts.
Tighten the belt by adjusting the belt adjustment bolt. Belt tension for new belts should be 57 to 65 lbs for the loosest belt in the set, then 45-50 lbs after run-in. If the belt tension falls below 25 lbs or chirping is heard as a start-up, re-tension belts. (If using the deflection method for belt tension, 3.8-4.3 lbs force at mid-span should give 7/32 inch belt deflection for a new belt 3.0-3.38 for a used belt for 7/32 inch belt deflection.
Tighten the four (4) motor slide bolts. Tighten the two electrical panel side slide bolts first then tighten the two pulley side slide bolts.

Limitation of Liability. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, TO THE EXTENT ALLOWABLE UNDER APPLICABLE LAW, UNDER NO CIRCUMSTANCES SHALL POWEREX BE LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, PUNITIVE, SPECULATIVE, OR INDIRECT LOSSES OR DAMAGES WHATSOEVER ARISING OUT OF OR IN ANY WAY RELATED TO ANY OF THE PRODUCTS OR GOODS SOLD OR AGREED TO BE SOLD BY POWEREX TO BUYER. TO THE EXTENT ALLOWABLE UNDER APPLICABLE LAW, POWEREX’S LIABILITY IN ALL EVENTS IS LIMITED TO, AND SHALL NOT EXCEED, THE PURCHASE PRICE PAID.
Warranty Disclaimer. Powerex has made a diligent effort to illustrate and describe the Products in its literature, including its Price Book, accurately; however, such illustrations and descriptions are for the sole purpose of identification and do not express or imply a warranty that the Products are merchantable, or fit for a particular purpose, or that the Products will necessarily conform to the illustrations or descriptions.
Product Suitability. Many jurisdictions have codes and regulations governing the sales, construction, installation, and/or use of Products for certain purposes, which may vary from those in neighboring areas. While Powerex attempts to assure that its Products comply with such codes, it cannot guarantee compliance, and cannot be responsible for how the product is installed or used. Before purchasing and use of a Product, please review the Product applications, and national and local codes and regulations, and be sure that the Product, installation, and use will comply with them.
Claims. Any non-warranty claims pertaining to the Products must be filed with Powerex within 6 months of the invoice date, or they will not be honored. Prices, discounts, and terms are subject to change without notice or as stipulated in specific Product quotations. Powerex shall not be liable for any delay or failure arising out of acts of the public enemy, fire, flood, or any disaster, labor trouble, riot or disorder, delay in the supply of materials, or any other cause, whether similar or dissimilar, beyond the control of Company. All shipments are carefully inspected and counted before leaving the factory. Please inspect carefully any receipt of Products noting any discrepancy or damage on the carrier’s freight bill at the time of delivery. Discrepancies or damage which obviously occurred in transit are the carrier’s responsibility and related claims should be made promptly and directed to the carrier. Returned Products will not be accepted without prior written authorization by Powerex and deductions from invoices for shortage or damage claims will not be allowed. UNLESS OTHERWISE AGREED TO IN WRITING, THE TERMS AND CONDITIONS CONTAINED IN THIS LIMITED WARRANTY WILL CONTROL IN ANY TRANSACTION WITH POWEREX. Any different or conflicting terms as may appear on any order form now or later submitted by the buyer will not control. All orders are subject to acceptance by Powerex.
