compressor to avoid stresses caused by changes in hot and cold conditions.
3.Piping supports should be anchored separately from the compressor to reduce noise and vibration.
4.Never use any piping smaller than the compressor connection.
5.Use 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.
SAFETY VALVES
Tank mounted compressors are shipped from the factory with safety valves installed in the tank manifold. The flow capacity of the safety valve is equal to or greater than the capacity of the compressor.
1.The pressure setting of the safety valve must be no higher than the maximum working pressure of the tank.
2.Safety valves should be placed ahead of any possible blockage point in the system, i.e. shutoff valve.
3.Avoid connecting the safety valve with any tubing or piping.
4.Manually operate the safety valve every six months to avoid sticking or freezing.
Assembling Modular
Medical System
MODULAR PLACEMENT
1. Unpack each module and discard all |
wood shipping materials. |
2. Locate frame assembly fasteners |
provided in parts pack [includes: |
fasteners, filter(s), isolation pads and |
inlet flex line]. |
3. Place modules at location designated |
(see picture below for proper |
arrangment of modules). Provide |
sufficient clearance around unit for |
servicing (see minimum clearance |
CONNECTING PIPING
1.Locate connection for piping at rear of unit for compressors module to receiver tank module.
2.Remove plastic caps that protect piping against contamination.
3.Connect flex joint to frame securely making sure flex line is not pinched or chinked.
4.Follow steps 1 to 3 for flex line from dryer package to outlet of receiver tank.
NOTE: All piping is provided and sealed for this portion of installation.
5.Locate and attach intake inline air filter to outside source air or header. Flex line is provided when attaching intake of compressors to rigid piping.
6.Connect outlet souce from filter package located on dryer module to outlet source piping.
Attach all inlet and
! WARNING outlet source
piping in accordance with NFPA 99 for Medical Gas.
ELECTRICAL WIRING OF MODULES
Provide electrical
! CAUTION power in accordance to NEC and local codes. Connection of wiring should be performed by a qualified electrician.
1.Connect wiring and flex conduit provided from each motor junction box to correct hole in bottom of control panel and starter.
2.Connect each temperature switch from the compressors to contacts located in control panel as marked for each temperature switch. Temperature switches shutdown the
compressor when temperature is above 400°F.
3.Connect wiring of unload solenoids to contacts located on control panel. The unload solenoid provides loadless starting of the compressors on off cycle.
4.Connect wiring from differential pressure switch at control panel. Differential switch wired to contacts in control panel provided for remote alarm.
5.Connect wiring from CO Monitor. A wire set is provided for power and the other for alarm. Wiring is marked for easy attachment.
6.Connect wiring from Dew Point Monitor. A wire set is provided for power and the other for alarm. Wiring is marked for easy attachment.
7.Dryer(s) need a separate properly protected power supply for each dryer. Standard voltage is 110 Volts. Other voltages are available. Check for voltage of dryer supplied and current rating provided on data plate of dryer.
NOTE: Units provided with desiccant drying systems are wired directly to the control panel provided.

Operation
Powerex package medical system operates at a maximum pressure of 100 PSIG. Compressor RPM’s are established by Powerex based on horsepower and operating pressure.
section). |
4. Install frame assembly fasteners to |
each frame joining the frames |
together. |
5. Lift corners of each frame assembly |
and install isolation pads provided. |
NOTE: Remove shipping brackets |
painted orange located at the base |
plate of each compressor module. |
This will allow spring isolators to free |
up reducing noise and vibration of |
the unit. |
