O
ption: P
SC
blower motor shall be a three-speed P
SC
type.
Option: 5-Speed ECM blower motor shall be a 5-speed ECM
ECM type. The 5-speed ECM blower motor shall be soft starting,
shall maintain constant torque over its operating static range,
and shall provide 5 speed settings. The blower motor shall be
isolated from the housing by rubber grommets. The motor shall be
permanently lubricated and have thermostatic overload protection.
5-speed ECM motors shall be long-life ball bearing type.
Option: Variable Speed ECM blower motor shall be a variable-
speed ECM type. The variable speed ECM blower motor shall be
soft starting, shall maintain constant cfm over its operating static
range, and shall provide 12 cfm settings. Variable speed ECM
motors shall be long-life ball bearing type.
Electrical
A
control box shall be located within the unit compressor
compartment and shall contain a 50VA or 75VA transformer, 24
volt activated, 2 pole compressor contactor, terminal block for
thermostat wiring and solid-state controller for complete unit
operation. Electromechanical operation WILL NOT be accepted.
Units shall be name-plated for use with time delay fuses or HACR
circuit breakers. Unit controls shall be 24 volt and provide heating
or cooling as required by the remote thermostat/sensor.
A
n Aurora microprocessor-based controller that interfaces with
a multi-stage electronic thermostat to monitor and control unit
operation shall be provided. The control shall provide operational
sequencing, blower speed control, high and low pressure switch
monitoring, freeze detection, condensate overfl ow sensing, lockout
mode control, LED status and fault indicators, fault memory, fi eld
selectable options and accessory output. The control shall provide
fault retry three times before locking out to limit nuisance trips.
A
detachable terminal block with screw terminals will be provided
for fi eld control wiring. All units shall have knockouts for entrance of
low and line voltage wiring. The blower motor and control box shall
be harness plug wired for easy removal.
Piping
Supply and return water connections shall be FPT copper fi ttings.
With vertical units, the condensate connection shall be a 3/4 in.
[19.1 mm] PVC socket with internally-trapped hose that can be
routed to front or side corner post locations.
Hanger Kit
(included with horizontal units only - fi eld installed)
The hanger kit shall consist of galvanized steel brackets, bolts, lock
washers, and isolators and shall be designed to fasten to the unit
bottom panel for suspension from 3/8 in. threaded rods. Brackets
shall not inhibit fi lter removal in any way.
Accessories
Thermostat (field-installed)
A multi-stage auto-changeover electronic digital thermostat shall
be provided. The thermostat shall offer two heating stages and
one cooling stage with precise temperature control. An OFF-HEAT-
AUTO-COOL-EMERG system switch, OFF-AUTO blower switch,
and indicating LEDs shall be provided. The thermostat shall display
in °F or °C.
Hose Kits – Ball Valves (field-installed)
A fl exible steel braid hose featuring Kevlar
®
reinforced EPDM
core with ANSI 302/304 stainless steel outer braid and fi re rated
materials per ASTM E 84-00 (NFPA 255, ANSI/UL 723 & UBC
8-1). Ball valve at one end; swivel connector with adapter at the
other end (swivel to adapter connection via fi ber or EPDM gasket).
Swivel connection provides union between heat pump and piping
system. The hoses feature brass fi ttings, stainless steel ferrules.
A full port ball valve shall be provided with integral P/T (pressure/
temperature) port on supply hose.
Specifi cations:
• Temperature range of 35°F [2°C] to 180°F [82°C].
• Max. working pressure of 400 psi [2757 kPa] for 1/2 in.
and 3/4 in. hose kits; max. working pressure of 350 psi
[kPa] for 1 in. and 1-1/4 in. hose kits.
