Cabinets shall have separate holes and knockouts for entrance of line voltage and low voltage control wiring. All factory-installed
wiring passing through factory knockouts and openings shall be protected from sheet metal edges at openings by plastic ferrules.
Supply and return water connections shall be copper FPT ttings, and shall be securely mounted ush to the cabinet corner post
allowing for connection to a exible hose without the use of a back-up wrench. Water connections that protrude through the
cabinet or require the use of a backup wrench shall not be allowed. All water connections and electrical knockouts must be in the
compressor compartment corner post as to not interfere with the serviceability of unit. Contractor shall be responsible for any extra
costs involved in the installation of units that do not have this feature. Contractor must ensure that units can be easily removed for
servicing and coordinate locations of electrical conduit and lights with the electrical contractor.
Option: Contractor shall install 2-inch (50.8mm) lter racks with removable access door and 2 inch (50.8mm) MERV11 pleated
throwaway lters on all units.
Option: UltraQuiet package (available on TS018-070 Units) shall consist of high technology sound attenuating material that is
strategically applied to the compressor and air handling compartment casings and fan scroll in addition to the standard
ClimaQuiet system design, to further dampen and attenuate sound transmissions. Compressor is mounted on specially
engineered sound-tested spring isolators.
Option: The unit will be supplied with internally factory mounted two-way water valve for variable speed pumping requirements. A
factory-mounted or eld-installed high pressure switch shall be installed in the water piping to disable compressor operation
in the event water pressures build due to water freezing in the piping system.
Option: The unit will be supplied with internally factory mounted automatic water ow regulators.
Option: The unit will be supplied with internally mounted secondary pump for primary/secondary applications, including one-pipe
systems.
Option: The unit shall be supplied with extended range Insulation option, which adds closed cell insulation to internal water lines,
and provides insulation on suction side refrigeration tubing including refrigerant to water heat exchanger.
Fan and Motor Assembly:
Blower shall have inlet rings to allow removal of wheel and motor from one side without removing housing. Units shall have a direct-
drive centrifugal fan. The fan motor shall be 3-speed (2-speed for 575V), permanently lubricated, PSC type, with internal thermal
overload protection. Units supplied without permanently lubricated motors must provide external oilers for easy service. The fan
motor on small and medium size units (006-048) shall be isolated from the fan housing by a torsionally exible motor mounting
system with rubber type grommets to inhibit vibration induced high noise levels associated with “hard wire belly band” motor
mounting. The fan motor on larger units (060 & 070) shall be isolated with exible rubber type isolation grommets only. The fan and
motor assembly must be capable of overcoming the external static pressures as shown on the schedule. Airow / Static pressure
rating of the unit shall be based on a wet coil and a clean lter in place. Ratings shall NOT be acceptable based on a dry coil and/
or no air lter.
Option: The fan motor shall be an ECM variable speed ball bearing type motor. The ECM fan motor shall provide soft starting,
maintain constant CFM over its static operating range and provide airow adjustment on its control board. The fan motor
shall be isolated from the housing by rubber grommets. The motor shall be permanently lubricated and have thermal
overload protection. A special dehumidication mode shall be provided to allow lower airows in cooling for better
dehumidication. The dehumidication mode shall be selectable via a jumper on the control board or may be controlled
externally from a humidistat.
Option: High static motors (sizes 018-060).
Refrigerant Circuit:
All units shall contain an EarthPure
®
(HFC-410A) sealed refrigerant circuit including a high efciency scroll or rotary compressor
designed for heat pump operation, a thermostatic expansion valve for refrigerant metering, an enhanced corrugated aluminum
lanced n and ried copper tube refrigerant to air heat exchanger, reversing valve, coaxial (tube in tube) refrigerant to water heat
exchanger, and safety controls including a high pressure switch, low pressure switch (loss of charge), water coil low temperature
sensor, and air coil low temperature sensor. Access ttings shall be factory installed on high and low pressure refrigerant lines to
facilitate eld service. Activation of any safety device shall prevent compressor operation via a microprocessor lockout circuit. The
lockout circuit shall be reset at the thermostat or at the contractor supplied disconnect switch. Units that cannot be reset at the
thermostat shall not be acceptable.
