HVAC DESIGN AND 14' WIDE MHU

(PACKAGED SYSTEM)

HVAC Wall Mounted Package Unit Notes

1. The MHU shall be equipped with a specifically engineered HVAC wall mounted package system based on the size and intended use of the MHU, in accordance with 24 CFR 3280.506, that is compatible with the HVAC wall mounted package system size and capable of maintaining an average temperature of seventy degrees Fahrenheit (70°F) in the MHU.

2. The HVAC wall mounted package system shall not cause vibration within the MHU. The HVAC wall mounted package system shall be mounted in such a way as to dampen the vibrations and any sound that accompany the packaged during operation cycles.

3. The HVAC wall mounted package system shall be able to maintain the temperature based on the coldest average temperature of the operating area of the MHU.

4. The HVAC wall mounted package system will require the manufacturer to have a current Alternative Construction letter from HUD.

5. The HVAC wall mounted package system shall be installed with a curb unit to minimize vibration and sound transmitted to the MHU.

6. A motorized room ventilator shall be installed in the HVAC wall mounted package system.

7. The thermostat shall be designed to work with the HVAC wall mounted package system.

8. The ceiling return air grill located in the bedroom shall accommodate a filter.

9. Duct penetrations thru ceiling board shall be sealed.

HVAC General Notes

1. See FEMA specifications for programable and configurable thermostat requirements.

2. Duct system shall be constructed of class 0 or class 1 circular insulated flex ductwork or equal. All ducts to be insulated with a minimum of R-4 insulation.

3. Metal supply registers shall be 8” x 8” TRUaire A500 series square extruded aluminum ceiling supply register (4-way distribution) with damper OR equivalent.

4. All supply ducts shall be in the roof attic space.

5. All supply duct seams and fasteners shall be sealed with UL-181A or UL-181B listed duct tape.

6. The manufacturer shall provide a duct pressure test report (See FEMA Spec for testing procedure) for each MHU duct system showing duct leakage of 5 percent or less prior to FEMA acceptance of the

MHU.

7. No construction debris or sawdust shall be left in the duct system.

8. The main supply and return duct trunks shall be galvanized sheet metal (min. thickness per HUD IB H-1-84) or Johns Manville Mat-face Micro-aire (Type 475 or 800) fiberglass ductboard or equivalent.

Duct to be installed per manufacturer's installation instructions.

10. N/A

11. N/A

12. A 12” x 6” return air register shall be located 8” above the floor in the TPS Compartment/ bathroom wall. A register shall be placed on each side of the wall.

13. The manufactured home manufacturer is responsible to assure the wall mounted HVAC unit provided has the following features:

a. Unit is designed to have a ceiling return air system as shown in drawing above. A return air system through the room the unit is in, is not acceptable.

b. Unit is designed so that when unit is operating, and any dampers are open that no direct openings from the outside to the inside of the MHU occur. Standing in the room and being able to see outside through any unit openings is not acceptable.

c. Unit is designed with an anti-vibration curb between the MHU and the wall mounted HVAC unit.

14. Bathroom exhaust fan location shall not be located next to the bathroom supply register.

15. One (1) 16" dia. jumper duct with transition fitting (201 square inches min.) each end or two (2) 12" dia. jumper ducts.
