Maintenance
See Appendix A for physical data on units, Appendix I for
component locations and Appendix J for troubleshooting
information. A more detailed description of major mainte-
nance items and timeframes follows.
Bi-monthly Maintenance
Bi-monthly maintenance should include:
Air Filters
The standard foam filters are washable. Under normal
conditions it is recommended that they be cleaned every
two months. More frequent cleaning may be required
under extremely dirty operating conditions. Use a vacuum
cleaner to remove the heaviest portion of accumulated
dirt, then wash with warm water.
A medium efficiency filter for the supply airstream is avail-
able from your Supplier. This filter is disposable and should
be replaced when it becomes dirty.
Drain Pans and Interior of Unit
With the filters removed from the unit, the foil faced insu-
lation surfaces and drain pans should be wiped clean with
a soft cloth and mild cleaning solution. Ensure that the
drain fittings are free from dirt and draining freely.

WARNING
Disconnect the main power switch to the unit before per-
forming service and maintenance procedures.
Balancing Procedure
Before proceeding with balancing, all windows, overhead
doors and walk-in doors should be closed and exhaust sys-
tems should be turned off.
The connections between the flow stations and the ducts
must be sealed with tape. Mount the magnehelic gauge in
a convenient location where it is level and will not vibrate
or be bumped. Zero the gauge. Measure the exhaust air
first as it is often the lowest due to a longer duct system.
With the fan speed at maximum, connect the hoses from
the FMS to the magnehelic gauge. If the needle falls
below zero, reverse the hose connections. Ensure that the
damper is wide open. Take a reading from the magnehelic
gauge and record it. Remove the FMS and place it in the
supply duct. This process is not necessary if the FMS is to
be permanently mounted.
Repeat the procedure. If the reading is higher in the sup-
ply duct, adjust the damper until the reading is the same.
If the reading is lower, return the FMS to the exhaust duct
and adjust the damper to obtain the same reading as the
supply duct.
