3. Introduction Central Mobile Enclosure • A compact and portable design. • Easy access from rear and side doors. • Automatic temperature control and fuel usage which responds to work site demands. • Low pressure atmospherically vented circulation system. No special boiler certification is required to operate the system.
Passive Heat Transfer Circulation Line Heat Exchangers The circulation line heat exchangers are the perfect solution for: • Heating and/or thawing cold or frozen ground. • Frost prevention. • Concrete curing and heating in subzero environments. This system can be applied to all types of concrete applications. Circulation line heat exchangers can be secured directly against the surface of the concrete or concrete forms.
• The system also allows for dual-temperature control. High temperature fluid can be provided to portable heat exchangers along with a lower temperature fluid for concrete cure and radiant floor heat applications. Optional Remote Manifold The multifunctional mixing/booster ensures maximum flexibility in the use of this system.
How the System Works The system uses a low-pressure, open-fluid loop distribution system with an atmospherically vented fluid reservoir. A central heating module warms the heat transfer fluid. This heated fluid is pumped through a distribution system loop, passing through heat exchangers in remote locations.
4. Setup (CME) The positioning of all the system components on the site will be influenced by several factors. Please read all the “Setup” section before beginning. Be sure to observe all local electrical codes and fire regulations when positioning the central heating module.
Electrical Requirements & Connection When determining the “central mobile enclosure” location on site, consider setting up near the electrical power supply. Note: This applies mainly to systems not equipped with a dedicated generator. • The main feed wiring must be adequately sized to carry the minimum ampacity shown on the water heater cabinet’s rating label.
Heat Transfer Fluid Specifications • The system is shipped with pre-mixed “HTF”, made up of 50% “Dowfrost ® HTF” or “Boss Chill PG” and 50% water*, by weight – freeze protection down to -28°F (- 33°C). • The “glycol/water mixture chart” below will provide you with more information on the proper mixture for your area.
Primary “HTF” Circulation Lines • If possible, position the primary circulation lines out of high traffic areas. • If primary “HTF” circulation lines are required, connect the primary circulation lines to manifold “supply” and “return” quick couplers at the back of the central mobile enclosure.

Heat Transfer Fluid “HTF” • A clean, properly maintained hot water system should not be drained unless there is a possibility of freezing, the boiler has accumulated a considerable amount of sludge or dirt on the water side, or draining is necessary to perform repairs. Very little sludge should accumulate in a water heater where little make-up water is added and where an appropriate water heater water treatment is maintained at proper strength.
“Y” Strainer Screen Cleaning Procedure • Clean the screen figure 48 (3-1) located inside the “Y”- strainer prior to every installation. • Remove the end plug from the end of the strainer outlet valve. • Position a container at the outlet valve. A couple of 5-gallon containers should do.
Figure 49-Marathon Electric Motor Torque Limiter Adjustment • Although the torque limiter clutch is factory (DRYAIR) set, periodic adjustments may be required. It is recommended the torque setting of the clutch be checked twice a season. With prolonged use, the two friction disks located on either side of the A- plate sprocket will eventually show wear.

Torque Adjust Procedure • Ensure that the adjusting nut is in a finger tight position. • If the adjustment nut is tighter than finger tight, loosen and complete previous step. • Match mark the adjusting nut with the hub. Using a torque wrench tighten the adjusting nut to 90ft*lb.
Gear Box Maintenance & Operation • Do not operate the unit without making sure it contains the correct amount of oil. Do not overfill with oil or injury to personnel, unit or other equipment may result. • For proper operation in subzero conditions, it is mandatory that the following oil be used: Spartan EP 320 Industrial Gear Oil ...any other gear oil will void warranty!
The preheater heats the glycol in the heat exchanger which in turn sends heated glycol to DRYAIR’S patented air and fuel preheater to provide a controlled constant air and fuel Figure 60-HTF Preheater temperature thus providing smooth start operations in cold weather.
If the operator decided they do not want to wait for the preheater to work, the DRYAIR unit will perform just like any of our competitor’s units that do not have a preheater option.
