COILS
- can be removed from unit through either end of unit. After removing piping and end
panels, remove bolts holding coil to structural frame at the air entering side of coil. The coil and
casing can then be pulled out.
(14)
WIRING AND COMPONENTS
- should be made and remain in accordance with National, State
and local codes that apply to this equipment. Check connections of wiring and retighten so
danger of a poor connection causing overheating and component failure through inadequate
current handling can be avoided. Good practice and safety indicates that before attempting
service to components, de-energize the systems and only after workers are clear of rotating and
electrical
devices
can
unit be energized again.

ULTRAVIOLET (UV) GERMICIDAL IRRADIATION LIGHTS
– The United States Environmental
Protection Agency (EPA) believes that molds and bacteria inside buildings have potential to cause
health problems in sensitive individuals
(1)
. If specified, Temtrol provides ultraviolet lights (UV-C)
as a factory-engineered and installed option in select commercial air handling products.
When UV lights are factory provided, polymer materials that are susceptible to deterioration by the
UV-C light will be substituted or shielded from direct exposure to the light. In addition, UVC-
radiation can damage human tissue, namely eyes and skin. To reduce the potential for inadvertent
exposure to the lights by operating and maintenance personnel, electrical interlocks that automatically
disconnect power to the lights are provided at all unit entry points to equipment where lights are
located.

WARNING
Equipment Damage, And Personal Safety Risk, From Ultraviolet (UV) Lights!
Temtrol does not recommend field installation of ultraviolet lights in its air handling
equipment for the intended purpose of improving indoor air quality. High intensity
C-band ultraviolet light known to severely damage polymer (plastic) materials and
poses a personal safety risk to anyone exposed to the light without proper personal
protective equipment (can cause damage to eyes and skin). Polymer materials
commonly found in HVAC equipment that may be susceptible include insulation on
electrical wiring, fan belts, thermal insulation, various fasteners and bushings.
Degradation of these materials can result in serious damage to the equipment.
Temtrol accepts no responsibility for the performance or operation of our air
handling equipment in which ultraviolet devices were in stalled outside of the
Temtrol factory.

AIR FILTER GAUGE
- "pick-ups" should point against air flow for best results without
restriction. Oil Manometers require split to operate properly (check zero set).
(17)
HUMIDIFIER
- strainer screen in supply line should be cleaned a few days after put in operation
and thereafter at least once a season - more often if much dirt is found in the screen. The trap
should be inspected at the same time strainer is cleaned.
(18)
UNIT HEATER OR ELECTRIC COIL
- should be checked for dirt on resisters and removed by
use of air only. DO NOT attempt cleaning without positive shut down.
