Room Air Blower
The DynaPack unit contains a 5 speed motor to allow a range of adjustments
so the proper cooling and heating speeds can be obtained after installation.
list the factory settings for the heating and cooling speeds based

on capacity. The factory settings should work for most installations but the
actual ductwork will dictate the best settings for your installation. The indoor
motor is permanently lubricated and does not require periodic re-lubricating.
The room air blower is controlled by the unit control board in addition to
the wall thermostat. With the thermostat fan switched to 'AUTO', the room
air blower will operate only when there is a call for heat or cooling. If the
thermostat fan switch is switched over to 'ON', then the room air blower will
run continuously. The control board will over ride the wall thermostat when
switched to 'AUTO'. There are various delay timings built into the board to
delay starting and stopping of the room air blower to increase comfort and
energy efficiency.
The furnace also contains safety limits that will operate when an abnormal
condition is detected. These limits serve a particular purpose and should
not be tampered with by relocating or wired around. If the furnace does not
operate, or the room air blower does not come on, or the a/c unit does not
operate, then call a licensed service technician to diagnose and repair.
The DynaPack unit is designed certified to operate up to 4500 feet above sea
level without modification for both the USA and Canada. Call Technical
Service at (229) 273-3636 for installations above 4500 feet.
Operation in extreme cold or snowy areas:
In those areas where the ambient temperature is consistently below 0° F,
indoor comfort can be improved by adjusting the heating blower speed to
obtain the maximum temperature rise allowed per the unit data plate.
A DynaPack unit installed on the ground floor must have the furnace intake
and exhaust above the anticipated snow fall for that area. Higher snowfall
than anticipated will block the furnace intake and lead to the unit shutting
off.
MAINTENANCE
WARNING! Disconnect all electrical power to the unit before
conducting any maintenance procedures. Failure to disconnect
the power could result in personal injury or death.
BURNERS:
The burners can be removed for cleaning or changing orifices.
PLEASE NOTE: This service must be performed by a qualified technician.
