Guide Specifications (Continued)

Filter Transducer -

A filter transducer shall be pro

vided and wired to the rooftop's control panel. The

unit controller shall display the pressure drop across

the filter[s]. Single transducer shall be provided to

measure pressure drop across both filter banks.

[Transducers shall be provided to measure pressure

drop across each filter bank].

Differential Pressure Gauge -

A flush mounted,

factory-installed differential pressure gauge shall be

provided to measure pressure drop across both filter

banks. [Flush mounted, factory-installed differential

pressure gauges shall be provided to measure pres-

sure drops across each filter bank.] Manufacturer

shall provide fully functional gauges complete with

tubing.

Evaporator Section

Cooling Coil -

Evaporator coils shall be direct ex-

pansion type with interlaced circuiting to assure com

plete coil face activity during part-load operation. Coil

tubes shall be copper with internally enhanced tubes.

Tubes shall be enhanced mechanically, expanded to

bond with the aluminum [copper] fins. All coils shall

be pressure-tested at a minimum of 450 psig.

[Evaporator coils shall be protected by the E-Coat

10-1 four coat process. Coils shall be dipped in a

phenolic coating, that shall provide substantial resis-

tance to corrosion of aluminum and copper.]

IAQ Drain Pan -

The main coil drain pan shall be dou-

ble-sloped with a condensate connection through the

base rail of the unit. Drain pans for cooling coils [and

humidifier] shall meet the requirements of ASHRAE

62.1. Drain pans shall be constructed of stainless

steel. [Provide a condensate overflow switch in the

primary drain pan.]

Intermediate Drain Pan -

Coils with finned height

greater than 48 inches (40 and 50 ton units) shall

have an intermediate drain pan extending the entire

finned length of the coil. The intermediate pans shall

have drop tubes to guide condensate to the main

drain pan.

UV Lights [Optional] -

Surface decontamination of

the evaporator coil and drain pan shall be provided

using UV lights. The UV lights shall be installed in

the downstream side of the evaporator coil/drain pan.

The UV lights (tubes) shall be shipped loose in pro

tective packaging for installation by the contractor.

Supply Fan Section

Fan -

The fan section shall be equipped with a SWSI

airfoil plenum wheel. Plenum fan shall be direct drive.

An access door shall be provided on the opposite

side of the control panel for fan/motor access.

Fan Motor -

Fan motors shall be NEMA design

ball-bearing types with electrical characteristics and

horsepower as specified. Motors shall be nominal

1,800 RPM, ODP type [TEFC type].

Mountings -

Fan and fan motor shall be internally

mounted and isolated on a full width isolator support

channel using 1-inch [2-inch] springs [and seismic

restraint].

Variable Air Volume (VAV) Fan Control -

VAV

supply fan control shall be accomplished by using

a VFD and supply fan motor combination matched

with supply fan to generate design performance at

appropriate fan speed. The VFD shall include an in-

tegral DC line reactor to reduce harmonic distortion

in the incoming and outgoing power feeds. If a DC

line reactor is not provided, an AC line reactor shall

be provided.

Single Zone VAV (SZVAV) -

In cooling mode, refrig-

eration capacity or compressor stages are cycled ON

or OFF to maintain DA temperature (DAT). In heating

mode, additional stages are cycled ON or modulated

to maintain DAT setpoint. The supply fan speed is

modulated to maintain zone temperature setpoint. The

unit uses either a BAS signal, RA temperature (RAT),

or a zone temperature sensor to determine zone tem-

perature and deviation from setpoint.

Redundant VFD [Optional] -

Direct drive plenum

(DDP) supply fans shall be provided with a 100%

redundant VFD. Redundant VFD shall automatically

operate in the event that the primary VFD fails.

All VFDs shall be factory tested and matched with

each unit.

VFD Reactor [Optional] -

A 3% impedance AC line

reactor shall be provided for the supply fan VFD.

Shaft Grounding Rings [Optional]

on motors shall

be provided to prevent electrical bearing fluting dam-

age by safely diverting harmful shaft voltages and

bearing currents to ground, increasing the motor lon-

gevity.

10.

Inlet Guards [Optional]

shall be provided on inlet of

supply fan.
