PREVENTIVE MAINTENANCE
The following should be checked periodically in order to keep
The Gaylord Ventilator operating at design efficiency:
Weekly
1. The detergent tank should be checked at least weekly and
kept full with a recommended detergent. (Refer to Page 13)
Monthly
1. The detergent system fittings should be checked at
least monthly. This is an airtight system and fittings
should be tight. (For complete details refer to the Deter-
gent Pump section on Page 12.)
2. At least monthly, at the conclusion of a wash cycle, open
the inspection doors of the ventilator and check to ensure
that the interior has been cleaned of grease, dust, and lint.
(Refer to Figure 7) If overall cleaning appears to be
inadequate, refer to "Trouble-Shooting of the Wash Sys-
tem", Page 27.
3. The main grease gutter of the ventilator should be
checked at least monthly to remove any foreign material
such as paper towels, order chits, etc.
Every Six Months
1. Exhaust fan(s) should be checked every six months for
belt tightness, belt alignment, and lubrication of neces-
sary moving parts.
NOTE: A blue lithium based grease is best suited for high
heat and speed bearing lubrication.
2. Check for proper velocity at air inlet slot. Refer to Pages
21 through 23 for method of checking velocity.
3. Test the "Internal Fire Mode" to check for proper damper
closure. Refer to Page 9 for instructions.
4. Detergent tank and foot valve should be cleaned every six
months.
