Heat pump unit shall include Reverse Cycle Defrost that
automatically begins a defrost cycle when microprocessor
determines criteria for defrosting has been met.
Defrosting shall be accomplished by systematically
ceasing heat pump operation, pausing to allow internal
refrigerant pressures to equalize, then operating the
compressor with the flow of refrigerant reversed, to allow
the hot gas to flow through the outdoor coil melting the
accumulated frost. Unit shall automatically resume heat
pump operation, after pausing to allow refrigerant
pressures to equalize, at conclusion of defrost cycle.

[Internal Condensate Removal (ICR) system for Heat
Pump Units. Unit shall have a positive Internal Condensate
Removal (ICR) system to permit unit to automatically
dispose of heat pump generated condensate with no
overflow to outdoor to occur during heating under outdoor
ambient of 55°F. Dry Bulb, 90% relative humidity; indoor
ambient 70°F. Dry Bulb, 52% Relative Humidity, for four
hours of continuous run time.]

Wall Case. (Wall case shall be constructed of heavy gauge,
zinc-coated, phosphatized steel, insulated and shall have a
protective baked-on enamel finish. Bottom critical points of
the steel wall case shall be treated with petroleum
microcrystalline wax for added corrosion protection and
shall meet ASTM B-117, 1800 hour hot air aerated salt spray
test. (Wall case shall be constructed of a non-corroding glass
reinforced polyester compound.)

Cases shall be installed through exterior walls where shown
on the plans and shall be level from side to side and from
front to rear to ensure proper operation of condensate
system(s). They shall be secured to the wall at both sides
using nails or other appropriate fastening devices. In no
instance shall fasteners be used through the bottom in order
to retain the water integrity of the bottom of the
wall case.

[Sub-Base. Each unit shall have a field installed UL listed
electrical sub-base. The sub-base shall be attached to the
lower inside flange of the wall case prior to installation in
the exterior wall and shall include adjustable screws at the
bottom corners to permit exact leveling of the wall case. The
sub-base shall have side panels adjustable from a minimum
of 2 3/8" to a maximum of 13 3/4" to enclose the area
under the wall case.]
