SAFETY CONSIDERATIONS
Installing and servicing air-conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install or
service air-conditioning equipment.
Untrained personnel can perform basic maintenance, such as
cleaning and replacing filters. All other operations should be
performed by trained service personnel. When working on air
conditioning equipment, observe safety precautions in litera-
ture, tags, and labels attached to unit.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for brazing operations. Have fire extin-
guisher available. Read these instructions
thoroughly
. Con-
sult local building codes and the National Electrical Code
(NEC) for special installation requirements.
GENERAL
These instructions cover the installation, start-up and service
of in-ceiling cassette fan coil units. See Fig. 1.
The following accessories can be used with 619FNF, FNQ

information for the following accessories:
• photocatalytic and electrostatic filter with mount
• air supply outlet obstruction kit
• wired room controller

WARNING:
Before installing or servicing system,
always turn off main power to system. There may be
more than one disconnect switch. Turn off accessory
heater power if applicable. Electrical shock can cause
serious personal injury.
CAUTION:
This system uses Puron® refrigerant
(R-410A), which has higher pressures than R-22 and
other refrigerants. No other refrigerant may be used in
this system. All equipment must be designed to handle
R-410A refrigerant. If unsure about equipment, consult
the equipment manufacturer.

Do not operate the unit without a filter
or with the grille removed. Damage to the unit or per-
sonal injury may result.
