4.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 temper- ature between 90_F (32_C) and 110_F (43_C) at outdoor ambient temperatures down to -20_F (-29_C).

5.Condenser Coil Hail Guard Assembly

a.Shall protect against damage from hail.

b.Shall be either hood style or louvered.

6.Unit-Mounted, Non-Fused Disconnect Switch:

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.

7.Convenience Outlet:

a.Powered convenience outlet.

b.Outlet shall be powered from main line power to the rooftop unit.

c.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.

d.Outlet shall be factory-installed and internally mounted with easily accessible 115-v female receptacle.

e.Outlet shall include 15 amp GFI receptacles with independent fuse protection.

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

g.Outlet shall be accessible from outside the unit.

h.Non-Powered convenience outlet.

i.Outlet shall be powered from a separate 115-120v power source.

j.A transformer shall not be included.

k.Outlet shall be factory-installed and internally mounted with easily accessible 115-v female receptacle.

l.Outlet shall include 15 amp GFI receptacles with independent fuse protection.
