PRE-STARTUP CHECKS
WARNINGS:
•
Electrically ground fan coil. Connect ground wire to ground terminal
marked “GND”. Failure to do so can result in injury or death.
•
Do not touch any rotating component with any object. Damage to the
equipment and personal injury can occur.
CAUTION: Any device such as a fan switch or thermostat that has been furnished by the
factory for field installation must be wired in strict accordance with the wiring
diagram that is supplied with the unit. Failure to do so could result in
damage to components and will void all warranties.
Before start-up, all of the components should be given a thorough check.
Optimal operation of this equipment requires cleanliness. Often after
installation of this equipment additional construction activities occur. Care
must be taken to protect the equipment from debris during these construction
phases.
Prior to starting the unit:
1.
Ensure supply voltage matches nameplate data.
2.
Ensure unit is properly grounded.
3.
With power off, check blower wheel set-screws for tightness and ensure
blower wheels rotate freely and quietly.
4.
Ensure fan coil is properly and securely installed.
5.
Ensure unit is sloped toward drain line.
6.
Ensure unit will be accessible for servicing.
7.
Ensure condensate line is properly sized, run, trapped, pitched and tested.
8.
Ensure all cabinet openings and wiring connections have been sealed.
9.
Ensure a clean filter is in place and of adequate size.
10.
Ensure all access panels are in place and secured.
11.
Check that the refrigerant coil connections and piping have been leak
checked and insulated as required.
MAINTAINING LOW
AIR LEAKAGE RATE
During installation, ensure that all grommets and gaskets remain intact on all
surfaces as shipped with the unit. Any knockouts, penetrations, and holes that
were exposed must be sealed to prevent air leakage. All access panels and
covers must be flush with each other and the cabinet. With these requirements
satisfied, the unit will maintain and achieve less than 2% air flow leakage when
tested in accordance with ASHRAE Standard 193.
