• V-belts are sized for maximum life with the pump package
blower/motor combination. Inspect periodically for proper
tension, and replace when worn.
Important!
V-belts stretch when new. Check belt tension after you have run them in.
At proper belt tension, the belt should deflect downward
1 /
64
” for every one inch span (1 mm every 6.4 cm) from sheave to sheave.
• Keep the pump package area clear of any debris that could be
drawn through the vent valve and into the blower while the
pump package is idling.
• Torque the motor and blower sheave bolts to 72 ft.-lbs.
(98 Nym).
• Check the moisture traps in the compressed air lines. Drain
as needed.
• Check the compressed air lubricator(s) for flow rate and
level. Use only 1 or 2 drops of oil per day when lubricating.
Adjust and fill as necessary.
• Inspect the silencer periodically for contamination. Silencer
fouling indicates poor filter maintenance at the vacuum
hopper or filter chamber. Fines may also be drawn into the
silencer through the pump package vent valve during the
dump cycle from poor housekeeping near the pump package.
!
CAUTION
Make sure you replace a contaminated silencer immediately
to avoid blower damage and possible fire hazard.
• Standard pump package TEFC motors do not require
lubrication or oiling. Optional motors may have different
requirements. Refer to the motor manufacturer’s
specification sheet in your Customer Information Packet.
• Keep the control panel and pump package junction boxes
securely closed to prevent component contamination.
