Hermetic compressors shall be internally sprung. The compressor shall have a dual level vibration isolation system. The compressor
will be mounted on specially engineered sound-tested EPDM vibration isolation grommets to a large heavy gauge compressor
mounting plate, which is then isolated from the cabinet base with rubber grommets for maximized vibration attenuation. All units
(except units with rotary compressors) shall include a discharge mufer to further enhance sound attenuation. Compressor shall have
thermal overload protection. Compressor shall be located in an insulated compartment away from air stream to minimize sound
transmission.
Refrigerant to air heat exchangers shall utilize enhanced corrugated lanced aluminum ns and ried copper tube construction rated
to withstand 625 PSIG (4309 kPa) refrigerant working pressure. Refrigerant to water heat exchangers shall be of copper inner water
tube and steel refrigerant outer tube design, rated to withstand 625 PSIG (4309 kPa) working refrigerant pressure and 500 PSIG
(3445 kPa) working water pressure. The refrigerant to water heat exchanger shall be “electro-coated” with a low cure cathodic epoxy
material a minimum of 0.4 mils thick (0.4 – 1.5 mils range) on all surfaces. The black colored coating shall provide a minimum of 1000
hours salt spray protection per ASTM B117-97 on all external steel and copper tubing. The material shall be formulated without the
inclusion of any heavy metals and shall exhibit a pencil hardness of 2H (ASTM D3363-92A), crosshatch adhesion of 4B-5B (ASTM
D3359-95), and impact resistance of 160 in-lbs (184 kg-cm) direct (ASTM D2794-93).
Refrigerant metering shall be accomplished by thermostatic expansion valve only. Expansion valves shall be dual port balanced types
with external equalizer for optimum refrigerant metering. Units shall be designed and tested for operating ranges of entering water
temperatures from 20° to 120°F (-6.7° to 48.9°C). Reversing valve shall be four-way solenoid activated refrigerant valve, which shall
default to heating mode should the solenoid fail to function. If the reversing valve solenoid defaults to cooling mode, an additional
low temperature thermostat must be provided to prevent over-cooling an already cold room.
Option: The unit shall be supplied with a hot water generator (desuperheater).
Option: The unit will be supplied with cupro-nickel coaxial water to refrigerant heat exchanger.
Option: The refrigerant to air heat exchanger shall be coated.
Option: Unit shall include ClimaDry
®
II reheat option. Only modulating reheat that will adjust capacity based upon supply air
temperature to provide “neutral” (72ºF, 22.2ºC) constant air temperature will be accepted. “Neutral” supply air temperature
shall be provided regardless of entering loop water temperatures (above 55ºF, 12.8ºC) or refrigerant condensing pressures.
Control of reheat must be accomplished via a humidistat or dehumidistat contact closure. Refrigerant circuit must be
AHRI certied. Approved equal manufacturers may provide pre-engineered integrated modulating hot gas reheat within
the unit cabinet, or the installing contractor in conjunction with the “approved equal” unit manufacturer can provide for
approval (during the submittal phase) an engineered system consisting of: a duct mounted hot water coil, small circulating
pump, modulating control valve, and associated piping using the discharge condenser water off of the unit as the heating
medium. All design costs and costs of eld installed items including additional power wiring to pump, and control wiring to
and from pump and control valve to unit shall be borne by mechanical contractor. Refrigerant circuits that are not AHRI
certied when the reheat option is applied will not be accepted. (See ClimaDry
®
submittal for more details and unit
availability.)
Drain Pan:
The drain pan shall be constructed of 304 Stainless Steel to inhibit corrosion. This corrosion protection system shall meet the
stringent 1000 hour salt spray test per ASTM B117. If plastic type material is used, it must be HDPE (High Density Polyethylene) to
avoid thermal cycling shock stress failure over the lifetime of the unit. Drain pan shall be fully insulated. Drain outlet shall be located
at pan as to allow complete and unobstructed drainage of condensate. Drain outlet for horizontal units shall be connected from pan
directly to FPT tting. No hidden internal tubing extensions from pan outlet extending to unit casing (that can create drainage
problems) will be accepted. The unit as standard will be supplied with solid-state electronic condensate overow protection.
Mechanical oat switches will NOT be accepted.
Vertical units shall be furnished with a PVC FPT condensate drain connection and an internal factory installed condensate trap. If units
without an internal trap are used, the contractor is responsible for any extra costs to eld install these provisions, and/or the extra
costs for his sub-contractor to install these provisions.
Electrical:
A control box shall be located within the unit compressor compartment and shall contain a 50VA transformer, 24 volt activated, 2 or
3 pole compressor contactor, terminal block for thermostat wiring and solid-state controller for complete unit operation. Reversing
valve and fan motor wiring shall be routed through this electronic controller. 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.
