MEDICAL TANK PRE-INSTALLATION & PLANNING GUIDE
(revised October 2004) Your Med-Fit Aquafit Tank can be installed in any of three different configurations, namely: 1. Completely above-ground 2. Partially in-ground 3. Completely in-ground Always consult with you local authorities first on their regulations governing your preferred installation configuration. Codes and requirements vary; advance planning will save you time and money. I. FLOOR LOAD CAPACITY Adequate load carrying subfloors are essential. Our standard Med-Tank models range from 22,750 lbs. (filled with water) to 37,350 lbs. This roughly equates to 237 lbs. per square foot to 260 lbs. per square foot. All units installed in-ground (partially or completely) must sit on a min. 4" thick concrete pad reinforced with a minimum 10x10 wire mesh. Especially in a multistory or roof top installation, you should consult with a registered structural engineer who can assess your building's floor load capacity. Additional reinforcement may be necessary (Example: A special support "pedestal" extending from ground-floor level up to the unit, set partially recessed through the upper floor). Generally, above-ground swim tanks require additional lateral support or bracing to prevent possible wall "bowing" when filled with water. Certain situations may require the advice of a structural engineer. II. PLACEMENT ACCESS Moving your new Med Tank into place is obviously easiest when your building is still under construction, before walls, doors, windows, or ceilings are completely closed in. In every application, look at hallways, corners, etc. While we can produce your tank in sections for final assembly at the site, it is often better to remove portions of a nonbearing wall or create an opening through existing windows. Here again, a little advance planning will go a long way. III. ROOM LAYOUT Leave space in your room design in front or to the side of your tank. Most health departments require a minimum 4' decking around 50% of the tank's perimeter. Always confer with your local authorities on this point prior to construction, since regulations vary considerably from community to community (this advise applies to standard and custom units). Always check with the tank fabricator for final height of vessel prior to placing the leveling slab. Carefully plan for adequate access to the tank itself, all support equipment in the equipment room/area, and electrical panels. Most municipalities spell out specific access requirements. Don't forget to leave enough room for easy equipment maintenance, service, and repair as a practical consideration, too. Plan for floor drains in the tank and equipment room/area so the tank can be drained. Hose bibs with approved anti-back flow devices must be provided for cleaning and tank refill as well as for supplying hydraulic pressure for a handicapped chair lift if required. Also consider floor drains or a continuous drain system for the deck area surrounding the pool. IV. ELECTRICAL SERVICE Determine the available capacity of your electrical panel. Generally, you will need a minimum 60 amps panel, depending on the equipment options you select (check with us for specifics). Most equipment can be supplied in 208 VAC, 220 VAC or high voltage 440 VAC, in single or three phase. The pool light requires a 110 VAC, GFI-protected circuit. All electrical hook ups must be done by a qualified, licensed professional in accordance with all applicable local and national electrical codes. V. INSTALLATION COST ESTIMATES It is difficult to give you an exact installation cost estimate, since prices depend on the specific requirements of your particular application, and prevailing local wages. To avoid over generalizing, we offer an estimated range we hope will be helpful. a.Site preparation (prior to unit delivery): Concrete cutting, pit excavation, removal of debris, concrete pad in bottom of pit, possible preparation of lift: from $3,200 to $6,400. b.Electrical sub panel in the equipment area capable of handling 60 to 100 amps, 200 VAC service, single phase: from $850 to $1,850 (depending on length of run and access to main electrical panel). Additional costs can be incurred if the main panel is not big enough, or has no additional room for breakers for the new panel. There will be a cost of approximately $1,000 to $1,800 for equipment hookup once it arrives. c.Labor for plumbing your unit to the equipment, water, venting the heater (if gas heater), drains, concrete work: between $1,500 and $4,500. d.Depending on the size of your pool, you need between 6 and 10 tons of sand for back fill. This also depends on how big the hole was dug. Cost of material range between $1,000 and $1,500. e.Depending again on the difficulty and unique requirements of the installation, there may be miscellaneous labor and material costs ranging from $1,000 to $2,000. To recap, estimated ranges of costs from local contractor and materials: { Site Preparation $3,200 to $6,400 { Electrical $1,850 to $3,650 { Plumbing and Labor $1,500 to $4,500 { Back fill and Materials $1,000 to $1,500 { Miscellaneous Labor and Materials $1,000 to $2,000 _______________________________________________ { Total Estimated Cost Range $8,550 to $18,050 VI. ROOM VENTILATION We do not recommend relying on the regular, existing room ventilation system to ventilate and/or dehumidify the Med-Tank room. Separate, independent room ventilation should be installed. A variety of energy-efficient, high tech systems are available through your contractor or Med-Fit. Please call for more information, if needed. We at Med-Fit are happy to consult with you by telephone prior to and during design and construction. We may also be able to assist you in obtaining permits by talking with local officials, provide line drawings, typical commercial plumbing and electrical schematics, recommended equipment room layouts, etc. 2 days on-site consultation during construction and unit installation with a Med-Fit technician is included with your purchase. Additional job site consultation is available, cost include out-of pocket expenses (room and board, transportation) and a $500 per day consultation fee. MEDICAL TANK INSTALLATION GUIDELINES
(revised February 2002) I. ACCESS Openings should be no less than 9’ wide x 7' high for standard size pools with no obstructions, narrow hallways or stairs. Units can be shipped in sections for smaller openings. Please check with us. II. PIT REQUIREMENTS Pit should be dug a minimum of two feet larger than vessel all around for placement of unit to insure no damage to piping, and to allow for access while leveling. Unit has to sit on a concrete pad at least the size of the unit with load bearing capability of 260 lbs. per square foot for the 12' long, 50" deep pool, and up to 350 lbs. per square foot for the 60" deep pool. III. STRUCTURAL SUPPORT For in-ground installation no additional structural support is required. After completion of hookup, pit is to be back-filled with sand slurry. During fill-up and testing, supports should be installed to prevent possible bowing, and later removed as sand is slurried in. For above-ground installation we recommend placing lateral supports to ground from approximately 4" below top of lip on tank (nailing blocks provided). This is not for aesthetic purposes, since side bowing might occur otherwise. Recommended lateral support drawings will be provided upon request. IV. PLUMBING All units come factory pre-plumbed and require job-site plumbing by others from the vessel itself to the equipment location. Diagrams are provided with each unit for plumbing per general health department requirements. A "P" trap with air gap for draining the unit must be provided. Potable water hookup requires an approved anti-back flow device. Please check for local code requirements.Typically, two plumbers can complete this work in 6-8 hours. No access to the pit area should be necessary after installation. Equipment can be located next to the unit or as far as 50 feet away. If equipment is located above water line, check valves must be installed to prevent siphoning. All pumps are gravity priming. Valves and quick-connect / disconnect unions should be installed to isolate pump and filter for cleaning or removal for repair. DO NOT ATTEMPT TO OPERATE SYSTEM WHILE THESE VALVES ARE CLOSED. DAMAGE MAY OCCUR. V. HEATING Unless otherwise requested, all units come with a 11 KW electric heater. If upgraded to a gas heater, a gas line should be run directly from gas meter to heater. Pipe size depends on distance of this run (to be installed by a licensed plumber). If gas is not available, we will size an electric heater based upon the pool area. VI. ELECTRICAL The total amperage requirements vary from 60 to 100 amps, depending on the number of pumps and electrical equipment installed. A sub-panel (with one GFI Breaker for the pool light) should be located in the equipment area. One emergency cutoff switch is required for all equipment. Lights must be hooked up via brass pool junction box located 18" above water line. All railings and equipment must be bonded together by an uninsulated #8 copper wire. Depending on local codes, one additional green #8 ground wire must be run (inside conduit) from light niche to junction box. One continuous green wire must be installed from the main panel to pool junction box. All equipment (except lights) run off 240 V single phase (additional voltages available). A licensed electrician should complete this work with a helper in 6-8 hours. VII. FILTRATION Standard systems are provided with a high rate sand filter, sized for a normal turnover rate of 60 minutes. When a DE (diatomaceous earth) filter is used, a separation tank is necessary for back washing. If filter is installed below deck, allow top clearance in order to allow servicing of filter; clearance should be a minimum of ¾ of filter height. VIII. CONTROLS Standard controls for circulation and booster pump are provided with spa-side remote control, timer, and emergency shutoff button. IX. STANDARD EQUIPMENT Med-Fit will provide all necessary equipment, controls, fixtures, and related instructions. Contractor will provide necessary permits, piping, valves, and check valves. After unit and equipment have been placed, typical installation time for two plumbers should not exceed 6-8 hours. X. EQUIPMENT AREA Provide a room to allow for two (2) pumps, a filter, heater, control and electrical panels. Note that NEC requires three (3) ft. clear in front of the electrical panels. In most cases a room six (6) ft. by eight (8) ft. will work, additional space will be required for a current generator or additional pumps. It is important to note that if a gas heater is specified, it must be vented to the outside with fresh air intakes to comply with building and safety codes. A floor sink must be provided and piped to the city sanitary system. Note: Piping from filter to floor sink must have air gap (do not hard plumb into drain). In addition, install one ball valve prior to entering floor sink to control flow. XI. DECK AREA All commercial installations require 4' deck area around 50% of the pool or spa. This deck can not be wood surfaced. Cementicous nonskid or skid-resistant tile shall be used, coping can be installed directly over the unfinished spa lip, and the deck area sloped to drain away from the spa, along with additional floor drains, to meet commercial building codes.
XII. VENTILATION In an indoor spa installation, an exhaust fan designed for pool systems should be installed to vent chlorine vapors and humid air to the outside. It should not be tied into the building air conditioning / ventilation system. Bromine can be substituted for chlorine to reduce the harshness and odor. XIII. TESTING As the factory has no way of knowing if the vessel or its piping has been damaged during shipment or when it is lifted in place, the contractor shall go by the following system: 1. After pool is leveled, place temporary bracing between pool wall and adjacent slab work to eliminate any possibility of bowing. 2. Run rough piping back to equipment area, stub up and plug. Fill vessel with water, then check all connections (including electrical conduit) for leaks. Additional pressure tests may be required by local code.If all is secure, complete hookups and start back fill operation. Leave vessel filled with water at least until back fill is completed. XIV. BACK FILL Slurry sand around spa and connecting piping. Compact with water and hand tamper. DO NOT use mechanical vibrator-type tamper. NOTES: Check all local codes for possible additional requirements before completing final installation and back-filling. Use only schedule 40 PVC pipes on all plumbing. Schedule 80 PVC or rigid piping will be required by code for electrical runs. Cut all pipes squarely, prime with PURPLE PRIMER, and use GRAY CEMENT. Keep bends to a minimum. Use 45 degree ells instead of 90 degree ells whenever possible. All spas are laminated in one piece: pre-plumbed with skimmer and main drain installed. Light niche must be set prior to installation (whether by manufacturer or by contractor), and stubbed out for easy access. All spas are water tested prior to shipping. Advisory assistance is available during installation. Please check with us.
