SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, main-
tenance, or use can cause explosion, fire, electrical shock, or
other conditions which may cause death, personal injury or
property damage. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this
product.
Follow all safety codes. Wear safety glasses, protective
clothing, and work gloves. Use quenching cloth for brazing op-
erations. Have fire extinguisher available. Read these instruc-
tions thoroughly and follow all warnings or cautions included
in literature and attached to the unit. Consult local building
codes and the current editions of the National Electrical Code
(NEC) NFPA 70. In Canada, refer to the current editions of the
Canadian Electrical Code CSA C22.1.
Understand the signal words — DANGER, WARNING,
and CAUTION. DANGER identifies the most serious hazards
which will result in severe personal injury or death.
WARNING signifies hazards that could result in personal inju-
ry or death. CAUTION is used to identify unsafe practices,
which would result in minor personal injury or product and
property damage.
Recognize safety information. This is the safety-alert
symbol ( ). When this symbol is displayed on the unit and in
instructions or manuals, be alert to the potential for personal
injury.
INTRODUCTION
Model 40TCQ fan coil units (see Fig. 1) are designed for
flexibility and can be used for up flow or horizontal applica-
tions. They require R-410A refrigerant and must be used only
with VRF (variable refrigerant flow) heat pumps and heat re-
covery units as shipped.
These units are available for application in VRF systems of
72,000 to 240,000 Btuh nominal cooling and heating capaci-
ties. See Fig. 2 for model number nomenclature. Tables 1 and 2
summarize physical and electrical data.
Model 40TCQ fan coil units are designed to meet current
low air leak requirements. Because of this, the units need spe-
cial attention in the condensate pan and drain connection area
and when brazing tubing.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all discon-
nect locations to alert others not to restore power until work
is completed.
CAUTION
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing and gloves when
handling parts. Failure to follow this caution may result in
personal injury.
CAUTION
R-410A refrigerant systems operate at higher pressures
than standard R-22 systems. Do not use R-22 service
equipment or components on R-410A refrigerant equip-
ment. If service equipment is not rated for R-410A refriger-
ant, equipment damage or personal injury may result.

INSTALLATION
Step 1 — Unpack and Check Equipment —
Unpack unit and move to final location. Remove carton, taking
care not to damage unit.
Inspect equipment for damage prior to installation. File
claim with shipping company if shipment is damaged or in-
complete. Locate unit rating plate which contains proper instal-
lation information. Check rating plate to be sure unit matches
job specifications. See Fig. 3 for unit dimensions.
Step 2 — Mount Fan Coil — Unit can stand or lie on
floor, or hang from ceiling or wall. Allow space for wiring, pip-
ing, and servicing unit.
When installing any fan coil over a finished ceiling and/or
living area, installation of a secondary drain pan under entire
unit to avoid damage to ceiling is recommended.
The 40TCQ fan coils can be installed for up-flow and hori-
zontal-left applications as factory shipped. Unit sizes 024 and
030 are A-coils. Unit sizes 036-048 are slab coils. See Fig. 4.
UP-FLOW INSTALLATION — If return air is to be ducted,
install duct flush with floor. Set unit on floor over opening.
Only use return-air opening provided. All return air must pass
through the coil. See Fig. 5.
HORIZONTAL INSTALLATION — Be sure installation
complies with all applicable building codes, which may require
installation of a secondary condensate pan.
NOTE: To ensure proper drainage for horizontal installations,
unit must be installed so it is within
1
/
8
in. level of the length
and width of unit.
1. Arrange support for unit by setting it in or above second-
ary condensate pan.
2. When suspending unit from ceiling, dimples in casing in-
dicate proper location of screws for mounting metal sup-
port straps.
See Fig. 6 and 7 for horizontal-left applications.
IMPORTANT: When unit is installed over a finished ceil-
ing and/or living area, building codes may require a field-
supplied secondary condensate pan to be installed under
the entire unit. Some localities may allow the alternative
of running a separate, secondary condensate line. Consult
local codes for additional restrictions or precautions.
