SAFETY CONSIDERATIONS
Installation and servicing of air conditioning
equipment can be hazardous due to system pres­
sure and electrical components. Only trained and
qualified service personnel should install, repair or
service air conditioning equipment.
Untrained personnel can perform basic mainte­
nance functions of cleaning coils and filters and
replacing filters. All other operations should be per­
formed by trained service personnel. When working
on air conditioning equipment, observe precautions
in the literature, tags and labels attached to the unit
and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and
work gloves. Use quenching cloth for unbrazing
operations. Have fire extinguisher available for all
brazing operations.
W.ARMNCi: llefore performing service or
maintenance operations on unit, turn off main
power switch to unit. Turn off accessoi\ healer
power switch if applicable, filectrical shock
could cause personal injury.
MODULAR SYSTEM INTRODUCTION
Field assemble the required 28 Series direct-
expansion (encased) coil and/or 40FS,40FQ,38HQ
accessory electric heater to 40FS fan section.
Combine fan section and coil for a split system fan
coil; fan section and accessory electric heater for
an electric furnace; fan section, coil and electric
heater for a heating and cooling unit. (See Table 2
for total height dimension of assembled units.)
