down no longer exists, after the anti-short cycle and random start timers expire. Should a fault
re-occur within 60 minutes after reset, then a permanent lockout will occur. A light emitting
diode (LED) shall annunciate the following alarms: high refrigerant pressure, low refrigerant
pressure, low water temperature and a high level of condensate in the drain pan (when
equipped with the optional low water temperature and high level condensate sensors). The
LED will display each fault condition as soon as the fault occurs. If a permanent lockout
occurs, then the fault LED will display the type of fault until the unit is reset. Safety devices
include a low pressure cutout set a 40 PSIG (280kPa) for loss of charge protection (freezestat
and/or high discharge gas temperature sensor is not acceptable) and a high pressure cutout
control set at 600 PSIG (4125 Kpa). An optional energy management relay that allows unit
control by an external source shall be factory installed. A terminal block with screw terminals
shall be provided for control wiring.
2.2.6 Piping: Supply, return water and condensate drain connections shall be brass female pipe
thread fittings and mounted flush to cabinet exterior with stainless steel, Braided hose kit with
swivel connectors.
2.2.7 Hot Gas Reheat: Provide factory hot gas reheat coil for humidity control.
2.3 Controls: Room thermostat shall be low voltage, remote-mounted with sub-base and
thermometer for controlling heating and cooling cycles. The fan selector shall include "AUTO-
ON" controls. Provide automatic changeover thermostats with fan that run continuously during
occupied mode. The room thermostats shall be manually adjustable by occupants and shall
indicate setting and temperature in degrees Fahrenheit. Provide humidity sensor and set point
control for hot gas reheat coil.
2.4 GEOTHERMAL LOOPFIELD: The contractor shall design the geothermal loop field and
provide a thermal performance guarantee. The contractor shall submit a list of 10 projects of
equal or larger size. Loop field piping shall be HDPE with thermally fused joints. Pipe shall
comply with ASTM D3035, ASTM D2683 for socket fusion fittings, and ASTM D3261 for
butt/saddle fusion fittings. Pipe shall be pressure tested at pressure recommended by
manufacturer. Test shall be witnessed by the engineer or owner’s representative. Provide 50
year warranty on pipe and loop assemblies.
3 EXECUTION
3.1 Installation: Install in accordance with producer's printed instructions. Anchor housing to
building with cadmium plated self-tapping screws, lag screws, or bolts, as directed by specific
construction. All mounting supports shall be provided by Division 23. Provide painted sheet
metal cover to protect unit from dripping from above.
3.2 Cleaning: Clean tar and all other soil from housing exterior. Leave ready for Division 7,
Caulking Work. Coordinate with general construction to ensure a water-tight seal.
3.3 Condensate Drain: Pipe trapped copper condensate drain to the point of disposal as shown
on the drawings. Pipe shall be full size of unit outlet. Refer to Division 23 section "Insulation"
for pipe insulation.
3.4 Startup: Check entire assembly for correctness of installation, alignment, and control
sequencing. Start all component parts in proper sequence. Make all adjustments required to
insure proper smooth quiet operation.
