Work from the pack count. The sets supplied are 8 Standard HotPacs with the SS-2, 12 with the M-2 and 24 with the M-4, on tanks of 10 gal, approximately 14 gal and approximately 27 gal, all three on casters.

Every HotPac size: Standard 10 x 12 in., Oversize 15 x 24 in., Spinal 10 x 18 in., Spinal large 10 x 24 in., Knee and Shoulder 10 x 20 in., Neck Contour 24 in., Half 5 x 12 in. and Hand 6.5 x 12.5 in. Only the Standard size ships with a mobile unit, and the rest are separate purchases from the HotPac range. A tank holds a mix of sizes at once, and an Oversize pack takes considerably more tank volume than a Standard one.

SS-2 4 hours, M-2 8 hours, M-4 8 hours to reach 160 F. Cool-down from 160 F is 4 hours, 3 hours and 4 hours respectively.

Always wrap a HotPac in a towel or terry cover before handling it or applying it to a patient, and DO NOT apply a HotPac directly to skin. Covers belong on the same order. The foam filled terry covers come in standard 19 x 27 in., standard 17 x 27 in., neck contour 25 x 16 in. and oversize 24 x 36 in., with or without pockets, and the all-terry microfiber covers in standard 19 x 27 in., neck contour 25 x 18 in. and oversize 24 x 36 in.

Do not apply a HotPac directly to skin. Do not apply over insensitive skin or in the presence of poor circulation. Do not use a HotPac directly over cuts, abrasions or wounds. Treatment time should not exceed 30 minutes, and a health care professional should be consulted before using HotPacs on non-communicative individuals.

A hospital grade electrical outlet with a ground terminal receptacle, which Chattanooga requires on all three models. Power is 1000 W at 110 to 120 V, 50/60 Hz, with an internal 15 amp fuse. There is also a risk of explosion if a unit is used in the presence of flammable anesthetics, so site the tank and its outlet well clear of any such store.

No plumbing. The tank is filled and drained by hand, so water changes are a manual job on whatever schedule your clinic sets, and the unit goes wherever there is a suitable outlet and a route to a sink. Let the tank cool before you drain it, put no chlorine additive in the water, and never retrieve a pack from the tank or replace one in it with an unprotected hand.

Yes. All three mobile models stand on casters, and the footprint measures 21 x 16 in. on the SS-2, 27 x 16 in. on the M-2 and 35 x 20 in. on the M-4, at a 33 in. cabinet height. Drain and cool the tank before a move.

One year, twelve months, from the date of original consumer purchase, with repair or replacement without charge within thirty days for a covered defect. It excludes misuse, unauthorised repair and failure to maintain the unit as instructed.

The E-1 and E-2 tabletop units hold 3 gal and 8 gal, ship with 4 and 6 packs, and have no casters, sitting on a bench or on the MB stainless steel cart. The mobile units start at 10 gal and 8 packs and move on their own wheels. Where more than one treatment room draws from the same tank, the mobile units are the ones sized for it, starting with the SS-2 at 10 gal and 140 lb filled.
