8.
Check transformer wires and terminals for wear or damage. Repair or replace as needed.
9.
Remove all mounting screws from original transformer.
10.
Using the existing fasteners, mount the new transformer to the original surface using all transformer
mounting holes locations. Check existing mounting screws for wear or damage. Replace if needed.
11.
Check the transformer is not loose and is level.
12.
Rewire the new transformer per your recorded data and per unit provided wiring diagram.
13.
Check all wire connections to the transformer are tight.
14.
Turn power back ON and test transformer with volt meter to confirm input and output voltages.
Plug Fans with Electronically Commutated (EC) Motors (EC)
Plug fan(s) with Electronically Commutated (EC) motors are standard equipment on all gPod floor mounted units.
Plug fan(s) with EC motors are maintenance free and only require visual inspection. The motors are sealed, have
maintenance free ball bearings and permanent lubrication. The only acceptable service is replacement.
WARNING
Disconnect all electric power sources to the unit before visually
inspecting a plug fan.
DO NOT OPEN THE TERMINAL COVER WITHIN THE FIRST
5 MINUTES AFTER DISCONNECTING OF ALL ELECTRICAL POWER.
If one of the fan internal safeties are triggered, the motor will stop via electronic controls and an “FAN FAILURE”
alarm will be indicated on the dap4 display.
Once the fan is stopped via internal controls, the motor will not restart automatically after the power source is re-
applied. The internal electronic controller must be reset by cycling the main electrical power OFF for a minimum of
twenty (20) seconds and then turned back ON.
If for any reason the rotor is blocked, the motor will electronically switch off. Before looking for blockage, make
certain to disconnect all electrical power sources to the unit. Once the blockage is cleared the motor will
automatically restart when power is turned back on.
If there is an alarm condition indicated as “NO AIRFLOW”, all active functions (cooling, heating and humidification)
will stop until the alarm is cleared.
If any form of trouble-shooting service is required inside the fan motor terminal box, do not open the plug fan
terminal cover within the first 5 minutes after turning OFF the electrical power to the unit.
NOTICE
. The controller has a time delay before the NO AIRFLOW alarm is
energized. The alarm is adjustable from 5 to 180 seconds, in 5 second
increments. On site where a voltage problem is known to exist, the delay can be
adjusted to eliminate “nuisance” alarms until the problem is corrected.
