Power-Pak shall be type PO-EM and shall cary U.L. listing. Each cord and plug set shall have an individual U.L. listing. Power-Pak shall consist of an electrical distribution assemly and a mechanical manifold assembly enclosed within a #16 ga. stainless steel duct and shall be of size and conformity noted on plans. Seams shall be flush welded and polished. Provide removable access panels in risers and pedestals for ease of maintenance. Electrical and utility manifold shall both have removable panels for ease of access. Power- Pak shall be provided with floor mounting pedestals as shown with vertical extensions to overhead hood at end risers. Interior of duct shall have interior welded stainless steel angle reinforcing frames. Provide stainless steel divider between electrical and mechanical sections. Mechanical sections shall have pipe clamp assemblies for supporting mechanical manifolds.

Electrical assembly shall be completely prewired with stainless steel connection plates. Connection plates shall be made for easy removal and resetting. Each receptacle shall be of standard NEMA configuration and provided with a spring-hinged weatherproof protective cover. Each receptacle shall be positively grounded to both receptacle connection plate and Power-Pak. Circuit breakers shall be of the all molded case type with no external pins. Breakers shunt trip mechanisms shall be internal. The high voltage shunt trips shall not use extra pole thereby making the breaker assembly more compact and trouble free. In proximity breaker layouts each circuit breaker shall be provided with a spring-hinged weatherproof protected cover.

Circuit breakers shall have 10,000 ampere interrupting capacity. Each receptacle shall be mounted onto a removable stainless connection plate. Vertical panel over each connection plate shall have engraved gravoply labels giving voltage, amperage, phase, item number, and description of equipment connected to the receptacle. Red gravoply warning name plates shall also be placed conspicuously on Power-Pak with "CAUTION HIGH VOLTAGE" AND "DO NOT DRILL INTO THIS POWER-PAK" warnings. Ground fault shall be supplied in accordance with the national Electric Code with all 120 volt and 240 volt single phase receptacles up to and including 30 amperes protected by ground fault circuit interrupters.

Provide in open end of control riser numerically coded indicator lights paralleled to indicator lights on each connection plate indicating the status of power to each piece of equipment. Control riser shall also include hood light switch with matching GFCl breaker and a manually operated emergency kill switch for personnel protection. Risers shall be provided with duplex convenience outlets with matching GFCI breakers. Control riser shall also be provided with an exhaust and air make-up fan control with adjustable time delay, magnetic motor controllers with manual resets, indicator lights, circuit breakers, power supply and fan switch requiring only one electrical connection to exhaust fan by electrical contractor.

Provide one Greitzer Energy Management systems (GEMS), Model HPFF to individually control each piece of equipment connected to the Greitzer Power-Pak. GEMS Model HPFF shall enable operator to realize a savings in energy consumption; reduction in peak demand and extended life of equipment connected to the Greitzer Power-Pak. GEMS Model HPFF shall be provided with a visual display panel to indicate to Management which pieces of equipment are in the operational mode at any given moment. Systems shall be easily programmable so management may change the schedule of equipment use as they deem necessary.

Cord and plug assemblies shall be rated to suit equipment being supplied with individual "U.L." labels indicating that it has met the standards of that organization. Cords shall be supplied with galvanized steel strain relief grips. All plugs shall be of the twist lock type meeting all NEMA configurations.

Mechanical manifold section of Power-Pak shall contain a fully connected manifold for steam supply, steam return, hot water, cold water and gas supply required by the drawings. All hot and cold water lines shall be made of copper. All steam and gas lines shall be made of black iron. Each manifold line including all joints shall be fully insulated with outside of all insulation labeled with description of item being transferred and direction of flow to simplify any future additions to the system. All lines shall be held rigid to interior wall of Power-Pak with stainless steel clamps.

Main feeds of each mechanical manifold shall be provided with a 1/4 turn ball valve to facilitate future changes. Each gas sub-manifold shall have an easily accessible 1/4 turn ball valve between main manifold and quick disconnect fitting.

Each mechanical manifold shall be provided with fittings to accommodate the flexible hose connections. All flexible hoses for water and steam shall be stainless steel. Pot filler faucets shall be provided as called for on drawings.

All flexible hoses for gas shall be Greitzer Model ADG, A.G.A. and C.G.A. listed hose assemblies constructed with a corrugated stainless steel inner jacket, stainless steel braided mesh exterior jacket and sanitary black. P.V.A. outer coating. All quick disconnects shall be supplied with two way shut off couplings with all gas couplings being A.G.A. and C.G.A. listed.

In compliance with Rule 96 of the National Fire Protection Association electrical receptacles shall be provided with a device which in case of fire will automatically break the circuit. Gas manifold shall be provided with an automatic fire fuel shut off which will automatically shut off gas in case of fire and reopen when the fire protection system is reset. Both automatic gas solenoid controls and manual gas shut off valves shall be mounted at gas inputs to Power-Pak.

Traps, cleanouts, line strainers, valves, pressure regulators and other fittings required for the connection of the outside mechanical trades to the Power-Pak system shall not be a part of this item.

Upon request of specifier, manufacturer must submit a copy of the U.L. test report and U.L. listing card for the Power-Pak and Cord and Plug Sets as well as A.G.A. and C.G.A. listing card for gas hose assemblies. Manufacturer shall also make available samples of cord sets, removable breaker and receptacle plate assemblies, quick disconnect gas hose assemblies, quick disconnect water hose assemblies, quick disconnect steam hose assemblies, operating samples, and drawings, and diagrams of component accessories for evaluation and approval to show manufacturer can meet the standards of the specifier. Information and samples shall be made available for evaluation and approval prior to equipment contractor preparing his submittal. Shop drawings containing details of construction and information relative to plumbing, electrical and steam assemblies shall be furnished to the local building dept. for their approval prior to manufacturer.

A representative of Greitzer shall be present at the jobsite during the period of installation of the Power-Pak equipment to instruct the various trades in the proper installation of their work in relation to the Power-Pak unit.

Greitzer is not to be responsible for any wiring or plumbing other than that furnished as part of our equipment.

Any equipment which proves defective in a period of twenty-four months after start-up or service, will either be repaired or replaced, at no expense to the Owners, by Greitzer unless such equipment has been damaged by improper installation, alterations by the Owner, or improper use of the equipment.
