Mobile Pad Staging and Operational Deployment

Proper pad placement is critical to prevent scan artifacts and structural fatigue. This manual provides direct step-by-step procedures for positioning the 48-foot trailer on the concrete pad in alignment with facility site-planning guides. Technicians are guided through operating the front hydraulic landing legs, clearing the fifth wheel, lowering the mechanical auxiliary support legs to within 0.5 inches of the sand shoes, and installing the heavy-duty rear stabilizing stands. Complete instructions are included for operating the rear air suspension control valves to inflate the air bags for stand insertion, followed by complete air suspension exhaustion so the trailer rests firmly on the stabilizing stands to eliminate vibration during medical imaging scans.

Facility Power Interconnection and Electrical Distribution

Operating a high-field magnetic resonance system on a mobile platform requires rigorous electrical safety protocols. The manual outlines incoming utility connections utilizing a 200A Russellstoll DF 2504 FRAB 0 facility receptacle and the provided 50-foot #3/0 4-conductor Type G 600V–2000V rated power cable. Operating personnel will find detailed coverage of the 480V AC main distribution panel, the 120/208V AC auxiliary panel, and the dedicated A-1 medical distribution cabinet. It delivers step-by-step instructions for transitioning from generator power to shore line power, incorporating mandatory 5-second pauses in the ‘OFF’ position to prevent electrical phase damage, as well as grounding requirements utilizing earth-driven rods within 5 feet of the hospital service receptacle.

Onboard Diesel Generator and Road Transport Protocols

When in transit between clinical sites, the trailer relies on an integrated front-housing Kohler Power Systems diesel generator fed by a 70-gallon dedicated diesel fuel tank. The manual documents cold start protocols, generator load management, warmup and cooldown five-minute timing phases, and regular filter changes. Road travel preparation includes stowing the stair system in underbody storage, pinning the auxiliary support legs into their highest transport position, retracting the hydraulic platform lift into its retaining cradles, engaging safety transport pins to actuate safety micro-switches, and inflating the air suspension to normal ride height (15 inches from trailer sidewall to ground level).

Environmental Control, Humidification, and RF Shielding Integrity

The Siemens Avanto magnet requires constant environmental stability. The documentation covers the closed-loop Northern Air commercial HVAC system, which incorporates dual refrigeration stages and an integrated water chiller supplying a 50/50 ethylene glycol mix to the magnet shield cooler compressor. Instructions specify return duct sensor operation, in-duct electric heaters, and the electrode-based steam cylinder humidifier capable of producing up to 12 pounds of steam per hour to maintain relative humidity strictly at 50% RH (limits 30% to 60%). Critical instructions also address the certified 90 dB radio frequency shielding enclosure, maintenance of beryllium copper finger stock door gaskets using denatured alcohol, and RF door interlock circuits that halt imaging scans if an access door opens.
