II. CHECKS
1.0 Monthly Checks
1.1 Visually inspect Air Handler for damage.
1.1.1 Motors, Drives - The motors and sheaves should
be inspected externally for evidence of damage to
the protective covering. An inspection is necessary
only if it is apparent that the control protection has
been disturbed. If this is found, the motor should
be re-protected by wrapping and tightly sealing
the control with plastic and inserting a desiccant to
absorb moisture.
1.2 Refrigerant Coils - Check holding charge pressure monthly
to be sure that the pressure has not dropped.
If pressure has dropped, the unit should be inspected for
signs of visible damage which may have caused loss of
pressure. If pressure drops more than 2 psi, the unit should
be pressure tested to locate the leak; the leak should be
repaired and the unit recharged with nitrogen to 5 psig
pressure. Note this in the comments section of the monthly
log sheet (See page 2).
1.3 Rotate fan shaft several revolutions by hand every month.
2.0 Quarterly Checks
2.1 Complete Assembly - The unit should be checked quarterly
to see that no damage has occurred to the protective
covering. Any apparent damage to the covering or units
should be noted in the comments section of the quarterly
log sheet (See page 2).
2.2 Grease bearings every three months. The greasing
procedure is explained in the product service manual.
