Installation and Maintenance Manual

UNT-SVX07D-EN 87
Pre-Start
Pre-Startup Checklist
Complete this checklist after installing the unit to verify all
recommended installation procedures are complete
before unit startup. This does not replace the detailed
instructions in the appropriate sections of this manual.
Disconnect electrical power before performing this
checklist. Always read the entire section carefully to
become familiar with the procedures.
Receiving
Unit Location
1. Ensure the unit location is adequate for unit
dimensions, ductwork, piping, and electrical
connections.
2. Ensure access and maintenance clearances around the
unit are adequate.
Unit Mounting
1. Ensure unit is installed level.
Component Overview
1. Ensure the fan rotates freely in the correct direction.
2. Ensure all unit access panels
and air grilles are in place.
3. Verify that a clean air filter is in place.
4. Properly set the damper position to meet the fres
h air
requirement.
Unit Piping
1. Properly vent the hydronic coil to allow water flow
through the unit.
2. Units with deluxe piping package: Tighten unions
ad
equately.
3. Set water flow to the unit properly if unit piping has the
circuit set
ter valve.
4. Check strainers (if supplied) for debris a
fter apply
system water.
5. Install the auxiliary drain pa
n and route the main drain
pan hoses to the auxiliary drain pan on vertical fan-coil
units.
6. Verify the condensate drain piping is complete for the
un
it drain pan.
7. Ensure the drain pan and condensate line are not
obstructed. R
emove any foreign matter that may have
fallen into the drain pan during installation.
Electrical
Note: Some circumstances may require the unit to run
before building construction is complete. These
operating conditions may be beyond the design
parameters of the unit and may adversely affect the
unit.
WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturer’s
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged. Failure to disconnect
power and discharge capacitors before servicing could
result in death or serious injury.
For additional information regarding the safe discharge of
capacitors, see PROD-SVB06A-EN
 Inspect unit and components for shipping damage. File
damage claims immediately with the delivering carrier.
 Check unit for missing material. Look for ship-with
options and sensors that may be packaged separately
from the main unit (see “Receiving and Handling,”
p. 10).
 Check nameplate unit data so that it matches the sales
order requirements.
 Check all electrical connections for tightness.
