3.Manual damper

a.Manual damper package shall consist of damper, air inlet screen, and rain hood which can be preset to admit up to 25 or 50% outdoor air for year round ventilation.

4.Perfect Humidity System:

a.The Perfect Humidity System shall be factory installed in single stage 580J04-07 and two stage 580J08-14 models with RTPF (round tube plate tin) condenser coils, and shall provide greater dehumidification of the occupied space by two modes of dehumidification operations in addition to its normal design cooling mode:

(1.) Subcooling mode further sub cools the hot liquid refrigerant leaving the condenser coil when both temperat- ure and humidity in the space are not satisfied.

(2.) Hot gas reheat mode shall mix a portion of the hot gas from the discharge of the compressor with the hot liquid refrigerant leaving the condenser coil to create a two-phase heat transfer in the system, resulting in a neutral leaving air temperature when only humidity in the space is not satisfied.

(3.) Includes head pressure controller.

5.Head Pressure Control Package

a.Controller shall control coil head pressure by condenser fan speed modulation or condenser fan cycling and wind baffles.

b.Shall consist of solid-state control and condenser coil temperature sensor to maintain condensing temperature between 90_F (32_C) and 110_F (43_C) at outdoor ambient temperatures down to -20_F (-29_C).

6.Propane Conversion Kit

a.Package shall contain all the necessary hardware and instructions to convert a standard natural gas unit for use with liquefied propane, up to 2000 ft (610m) elevation.

b.Additional accessory kits may be required for applications above 2000 ft (610m) elevation.

7.Flue Shield

a.Flue shield shall provide protection from the hot sides of the gas flue hood.

8.Condenser Coil Hail Guard Assembly

a.Shall protect against damage from hail.

b.Shall be either hood style or louvered.

9.Unit-Mounted, Non-Fused Disconnect Switch (Available on units with MOCP’s of 80 amps or less):

a.Switch shall be factory installed, internally mounted.

b.National Electric Code (NEC) and UL approved non-fused switch shall provide unit power shutoff.

c.Shall be accessible from outside the unit.

d.Shall provide local shutdown and lockout capability.

10.Convenience Outlet:

a.Powered convenience outlet.

(1.) Outlet shall be powered from main line power to the rooftop unit.

(2.) Outlet shall be powered from line side or load side of disconnect by installing contractor, as required by code. If outlet is powered from load side of disconnect, unit electrical ratings shall be UL certified and rated for additional outlet amperage.

(3.) Outlet shall be factory installed and internally mounted with easily accessible 115-v female receptacle. (4.) Outlet shall include 15 amp GFI receptacles with independent fuse protection.

(5.) Voltage required to operate convenience outlet shall be provided by a factory installed step-down trans- former.

(6.) Outlet shall be accessible from outside the unit.

(7.) Outlet shall include a field installed “Wet in Use” cover.

b.Non-Powered convenience outlet.

(1.) Outlet shall be powered from a separate 115/120v power source.

(2.) A transformer shall not be included.

(3.) Outlet shall be factory installed and internally mounted with easily accessible 115-v female receptacle. (4.) Outlet shall include 15 amp GFI receptacles with independent fuse protection.

(5.) Outlet shall be accessible from outside the unit.

(6.) Outlet shall include a field installed “Wet in Use” cover.
