Fig. 30 — Assembled in Horizontal Configuration
Service Clearance
Provide adequate space for unit service access (fan shaft and coil
removal, filter removal, motor access, damper linkage
access, etc.).
Condensate Drain
To prevent excessive build-up of condensate in drain pan, ade-
quate trap clearance (trap depth) must be provided beneath the unit
as indicated in Fig. 31. See Installation, Condensate Drain section
for additional details.

External Vibration Isolators
Install vibration isolators per certified drawings, and in accordance
with the job specifications and the instructions of the vibration
isolator manufacturer. The coil piping must be isolated or have a
flexible connection to avoid coil header damage because of unit
motion. A flexible connection should be installed at the fan
discharge.
Figure 23 shows isolation locations for overhead suspension of
unit.
INSTALLATION
Condensate Drain
Install a trapped condensate drain line at unit drain connection. All
39S units have a 3/4 in. FPT condensate drain connection.
Measure maximum design negative static pressure upstream from
the fan. Referring to Fig. 31, height “H” must be equal to or larger
than negative static pressure at design operating conditions. Prime
enough water in trap to prevent losing seal (Differential 1). When
the fan starts, Differential 2 is equal to the maximum negative stat-
ic pressure.
Provide freeze-up protection as required.
Bottom Return Economizer Package (BREP) and
Horizontal Bottom Return Economizer Package
(HBREP) (39SR Unit)
Economizers are used with 39SR units for automatic
sensor-controlled introduction of outdoor air into the system
through an electro-mechanically controlled damper.
To install BREP:
1. Check for correct number of parts shown in Fig. 32 and the
following list.
1 – Economizer assembly
1 – Barometric relief hood
1 – Outdoor air hood
1 – Hardware bag
2. Disconnect all power to unit.
CAUTION
RECOMMMENDED: 39SHC, 39SHF, and 39SV units have
an auxiliary condensate drain which should be piped to a con-
densate overflow sensor or safe drain location or both. Failure
to follow this warning may cause damage to equipment and
property in the case of condensate overflow.
In addition, the International Mechanical Code (IMC) section
307.2.3 requires the use of auxiliary drain pans. Many munici-
palities have adopted this code. Carrier holds that this practice
represents the standard for professional installation whether or
not this code has been adopted in a specific municipality or ter-
ritory. As such, water damages that would have been prevented
had an auxiliary pan been deployed will not be considered for
compensation. This position is taken regardless of whether the
source of the moisture was specified as a potential failure
mode in the applicable building code or not. A freeze burst,
cracked drain pan, failed weld, or corrosion induced leak are
some of the potential failure modes that are mitigated when an
auxiliary pan is properly installed. Professional installers rec-
ognize the value of protecting customer assets against foresee-
able events. Customers who choose to avoid the cost of com-
mon protective measures waive their right to seek damages
when those foreseeable events occur. If the product is located
above a living space or where damage may result from con-
densate overflow, install a watertight pan of corrosion-resistant
metal beneath the unit to catch over-flow which may result
from clogged drains or from other reasons. Provide proper
drain piping for this auxiliary pan. Consult local codes for ad-
ditional precautions before installation.
