MedPlus® Manifold
TECHNICAL DATA SHEET
Figure 1. MedPlus® Manifold
Purpose
The MedPlus® Manifold reduces cylinder pressure to line pressure for distribution through the facility’s medical gas distribution system.
The manifold monitors the pressure of the cylinder banks and automatically switches to the reserve supply when the primary bank is exhausted. “In Use”,
“Ready”, and “Empty” lights on the front panel indicate the status of each cylinder bank. Contacts are provided for connection to external alarm systems.
Standards
MedPlus® Manifolds meet all applicable codes and standards:
• National Fire Protection Association (NFPA) 99
• Canadian Standards Association (CSA®

)
Z-305.1
• Underwriters Laboratories Inc.®

Description
MedPlus® Manifolds are available for oxygen, nitrous oxide, air, carbon dioxide, helium, nitrogen, argon, xenon, oxygen and carbon dioxide mixture, oxygen and helium mixture, oxygen and nitrogen mixture, and oxygen and nitrous oxide mixture.
MedPlus® manifolds use National Pipe Thread (NPT) connections.
t040_001
NOTE:
This manifold is not suitable for liquid oxygen or liquid nitrogen cylinders. For those manifolds, refer to the MedPlus® Manifold for Use With Liquid
Cylinders Technical Data Sheet (tds038).
The MedPlus® Manifold is designed for left and right cylinder banks of equal capacity. When one bank is exhausted, the manifold automatically switches to supply gas from the other bank. Status lights on the front panel indicate the switch-over. Remote visual and audible alarms can be connected to the manifold circuit board. Gauges on the front panel continuously indicate pressures within both of the cylinder banks and the delivery lines.
Each MedPlus® Manifold includes an electrical transformer with a utility box for external mounting, and an NPT-to-tube union for connection to the medical gas delivery line.
Also included are wall-mounting or floor-mounting legs as specified and the correct number of blind glands and union nuts, header extensions, pigtails, and mounting brackets required for installation. If the manifold will be floor-mounted, header support legs

Service
Service will be provided by a Hill-Rom-approved service organization. Third party service is not acceptable.
Submittals
Hill-Rom will submit documentation detailing specified design and performance requirements, including delivery pressure and flow capabilities.
Warranty
Please refer to the service manual for the warranty.
Electrical System
A step-down transformer is provided with each manifold for installation inside the manifold cabinet or at a remote location. The transformer requires connection to a 120 V AC Essential Electrical
Distribution power and delivers 24 V AC to manifold circuit board where it is converted to V DC to power the solenoid, relays, LEDs, and switches.

Both wall-mounted and floor-mounted manifolds are
24" (61 cm) in width and 66" (168 cm) in height. See
table 1 for cylinder lengths. Lengths of wall-mounted
or floor-mounted manifolds vary with the number of cylinders attached. The maximum recommended number of cylinders for the MedPlus® Manifold is 28
(14 on each side). For MedPlus® Manifold dimensions, see figure 2 on page 4.

Installation Information
Installation instructions are included in the manual shipped with each manifold. When planning installation, note the following additional information:
1.
The manifold room must not be used for any purpose other than the manifold and cylinder storage. The manifold room door must be lockable. Provide 3 sets of keys.
2.
Locate the manifold and cylinders in a vented room on the ground floor, by an exterior wall with easy access to the loading dock. If manifolds are placed out of doors, they should be covered to prevent exposure to direct sunlight and rain.
3.
Provide dedicated mechanical venting or natural venting through an opening of at least 72 sq in
(0.05 sq m) total free area. Venting must be to the outside of the building and not into a major egress corridor. If vents are open to corridors, they must be provided with a fire damper. Avoid locations near high temperatures, such as boiler rooms.
4.
According to NFPA 99, the temperature of the manifold room should not go below 32°F (0°C) or above 100°F (38°C). The temperature of the cylinders should never exceed 130°F (54°C). The heating in the manifold room must be steam, hot water, or other indirect means. Do not use electric heaters, gas heaters, etc., which have open flames or may be explosion hazards.
5.
Allow sufficient space to manage the cylinders and the manifold, and to store empty and reserve cylinders.
6.
The manifold room must constructed out of at least 1 hour fire-rated material, and all interior finishes must be noncombustible.
7.
The manifold room must meet NFPA 99 and the
National Electrical Code® standards for ordinary locations. The manifold room must meet any local electrical code requirements. All electrical fixtures, including receptacles, must be in fixed locations at least 60 "(152 cm) above the finished floor.
8.
Provide chains or cables to restrain cylinders, including empty and reserve cylinders.
9.
Do not locate manifolds in the same room with medical air or medical vacuum plants.
10. Do not repeatedly bend, sharply bend, or twist the pigtail’s copper tubing.
11. Each pigtail must be connected to a cylinder to prevent gas leaks. If there is a pigtail with no cylinder, remove the pigtail from the header and seal the header inlet securely with a gas-specific blind gland and nut.
12. Install the manifold according to Hill-Rom’s instructions. Test the manifold for leaks after
January 16, 2001 tds040 Page 7 of 8
MedPlus® Manifold
TECHNICAL DATA SHEET
complete installation by using full cylinders of gas and an approved, oxygen-compatible leak test solution.
13. Electrical contractor must connect 120 V AC
Essential Electrical Distribution power to the manifold power supply and wire power supply to the manifold according to Hill-Rom’s instructions. The electrical contractor must also wire and test alarm functions.
14. Relief valves must be piped to the outside of the building. Ensure the vent is turned down and screened. The vent must be located at least 120"
(305 cm) above the final grade.
15. If required by NFPA 99, install an Emergency
Pressure Oxygen Inlet for connection of a temporary oxygen source.
16. Nitrogen may be stored with oxidizing agents.
17. Do not store nitrous oxide and oxygen with flammable and combustible materials.
18. Oxygen supplies greater than 20000 cu ft
(566 cu m) must comply with NFPA 99.
19. Nitrous oxide supplies greater than 3200 lbs
(1451 kg) or 28000 cu ft (793 cu m) should comply with CGA G8.1.
20. Review NFPA 99 to ensure compliance with all applicable standards.
