SmartSource™ Single-Stage Vertical Water Source Heat Pumps

SmartSource™ water source heat pumps are designed using
the latest technology to achieve some of the highest ef­ficiency single-stage products in the market today. McQuay
is the first manufacturer to offer ECM variable fan motors as
a standard option across the whole product line, even in the
smallest cabinet sizes, for unmatched performance and com­fort in the industry.
High EERs that far exceed ASHRAE 90.1 standards make these
units perfect for LEED projects and rebate opportunities. All
units are available geothermal ready from the factory with
many features to easily match your application requirements.

1. ECM Fan Motor: 4 field adjustable cfm settings and 28

programmed cfm values provide a wide range of airflow
selections for quieter operation and lower energy con­sumption.

2. Copeland K-5 Scroll: or LG Rotary available in a variety

of commercial voltages, mounted on a double isolation
system for reduced sound and vibration.

3. Refrigerant Circuit: Utilizes R-410A refrigerant with a bi-

flow thermal expansion valve for easy metering and four
way solenoid reversing valve.

4. MicroTech III Controls: Easy open-protocol integration

with optional LonWorks® or BACnet®.

5. Unit Status LED: Instant visuals on unit operation for

easy troubleshooting and advanced diagnostics.

6. 4-Sides Filter Rack with Standard 2” or Optional 4”
Filters: Designed for easy filter maintenance. MERV 8 &

13 filter options with gasketed filter rack meet LEED-NC
EQc5 applications with leakage rate at less than 4 CFM
per square foot of filter area at 0.5”ESP.

7. Stainless Steel Drain Plan: Sloped with lipless drain con-

nection for positive condensate flow, meets ASHRAE 62.1
Section 5.11.

8. Flush Mounted Fittings: Easy one wrench connection,

securely fastened to the cabinet corner posts.

9. Blower and Motor Orifice Ring: Easy service removal

without having to remove the blower housing or discon­necting the unit from the duct work.

10. Durable Cabinet Construction: Heavy gauge steel with

powder coated textured paint, lined with cleanable foil­faced insulation on the airside.
