Unit Options
Export packaging
Can be either open or closed crate and with optional shipping
bag. A wooden skid and a shrink-wrapped bag covering the
entire unit and protecting it from possible dirt and grime
accumulation during transit are standard.
Pumpout Unit, with or without storage vessel
Available in a variety of sizes, single-phase or three-phase,
with and without tanks. Contact your Daikin McQuay sales
office for details.
Extended warranties
Extended 1, 2, 3, or 4 year warranties for parts only or for parts
and labor are available for the compressor/motor only, the
entire unit, or the entire unit including refrigerant.
Spring vibration Isolators
Spring isolators for use in special situations requiring
extremely low vibration and sound levels.
Witness performance test
The specified full and/or part load tests, as ordered, are
performed in the presence of the customer under the
supervision of a factory engineer and include compilation of
the test data onto an easy-to-read spreadsheet. Tests are run to
AHRI tolerances of capacity and power. Travel and local
expenses are not included.
Certified performance test
The specified full and/or part load run tests, as ordered, are
performed under the supervision of a factorry engineer; data is
compiled, certified and transmitted to the customer. Tests are
run to AHRI tolerances of capacity and power
Refrigerant charge
Holding charge of Nitrogen or R-134a. Shipping with a full
charge of R-134a is standard.
Knockdown shipment
Several options for a knockdown shipment to facilitate unit
placement. See page 32 for details.
Vessel Options
Marine water boxes
Provides tube access for inspection, cleaning, and removal
without dismantling water piping.
Flanges (Victaulic connections are standard)
ANSI raised face flanges on either the evaporator or
condenser. Mating flanges are by others.
Water side vessel construction of 300 psi (150 psi is
standard)
For high pressure water systems, typically high-rise building
construction.
Epoxy coating
Evaporator and condenser tube sheets,heads and marine boxes
can be epoxy coated for corrossion protection.
Single insulation - evaporator shell / heads / suction piping
0.75-inch insulation on cold surfaces. Insulation, either
optional factory-installed or field-installed is required on all
installations.
Double insulation - evaporator shell / heads / suction piping
1.5-inch insulation on cold surfaces (0.75-inch on suction
piping) for low fluid temperatures and/or high humidity .
Tube size, wall thickness and material
A wide range of tube options are available to accommodate
most flow rates and fluids. Standard wall thickness is 0.025 in.,
optional 0.028 in. or 0.035 in.
Controls Options
BAS interface module
Factory-installed on the unit controller for the applicable
protocol being used (Can also be retrofit):
•BACnet MS/TP
•BACnet IP
•BACnet Ethernet
• LonWorks
• Modbus RTU
Electrical Options
High short circuit current rating
35kA, 65 kA and 100kA (at 460V) panel rating available with
a matching circuit breaker.
Low Harmonic VFD Option
The Low THD option (M3) model VFD has been tested to meet
SEMI F47-0706 standard for voltage sag immunity. This is a
standard from the semi-conductor industry that specifies
various scenarios regarding voltage sag intensity (percent of
voltage remaining during sag) and duration (in cycles or
seconds). The chiller will remain on-line during a voltage sag
that meets the criteria in this testing protocol.
EMI filter
Factory-installed option. Radio interference filter.
Ground fault protection
Protects equipment from arcing ground fault damage from
line-to-ground fault currents less than those required for
conductor protection.
Input power meter
Allows display of phase amps and volts on the operator
interface screen.
Special Order Options
The following special order options are available; requiring
factory pricing, additional engineering and possible dimension
changes or extended delivery:
Special Order Options:
1 Non-standard location of nozzle connections on heads
(compact water boxes) or marine water boxes
