INSTALLATION
INSTRUCTIONS
MECHANICAL
This wall fan coil unit is designed to be mounted in a
horizontal configuration only. The weight information for
each model can be found in the
specifications
section
of this document; take care to ensure the supporting
members are rated to support the fan coil load. When
installing, clearances must be provided as a provision
to allow maintenance/service of the unit. Additionally,
clearance around the unit increases performance by
allowing airflow.
ELECTRICAL
Electrical Connection: An appropriate strain relief device
must be used to attach the power wires to the terminal
box. A 13/16in (20.6mm) hole is designed on the terminal
box for field installation of the strain relief device. A
main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in
the fixed wiring in accordance with the relevant local and
national codes.
WIRING
WARNING: Turn off the breaker until all electrical
connections are made.
WARNING: This unit must be connected to a protective
grounding system.
All wiring shall comply with local and national codes.
Before attempting system installation, verify that
the electrical system and wiring are adequate for
supplying the required ampacity to the wall fan coil
unit (see
specifications
section of this document).
High and low voltage terminal blocks are provided in
the unit’s electrical panel. Reference
figure 3
for wiring
diagram. Making improper electrical connections could
cause damage to the equipment or harm to servicing
personnel. Never perform electrical work unless properly
trained and licensed and aware of relevant electrical
codes and requirements.
There are different wiring configurations depending on
selected options, but all units will include high and low
voltage terminals as well as a ground terminal.
Unit components are wired to the terminal block of the
indoor unit. Wiring can be accessed from the terminal
block inside the control box.
