• Close spray chamber door and secure door hasps
• Place hands in gloves, secure the part, grip spray hose firmly,
direct hose at parts and depress foot pedal to activate spray. Adjust
nozzle for desired spray pattern.
• If unit will be idle for an extended period, door should be latched in
open position.
• If equipment is used in near freezing conditions, protect pump after
use by draining cleaning fluid, then pumping antifreeze solution
through system. This will coat the pump interior. Use antifreeze with
rust inhibitors. Follow this same procedure if Tempest unit will not be
used for an extended period.
MAINTENANCE
disconnect all power sources to unit before performing any
maintenance.
Changing the Cleaning Fluid
be sure reservoir and liquid are cool before beginning maintenance.
for tempest 10 and 10S:
1. Open lower cabinet door. Unplug heater cord from lower socket in
outlet box located at right front of inside lower cabinet (Fig. 4, p.5).
If unit is equipped with an oil skimmer, also unplug its cord from the
adjacent outlet.
2. Disconnect drain hose (Fig. 1, p.5) and lower hose into pail
reservoir. Remove intake hose from pail reservoir.
3. Remove entire pail assembly from shelf.
4. Loosen snap ring securing lid to pail and remove lid. (Fig. 2 & 3, p.5)
Always dispose of used cleaning fluid properly in accordance with the
MSDS sheet, manufacturer’s instructions and State and Federal
regulations. This could involve removing the oil from the top, metal
chips and other solids from the bottom, bringing the pH to 9 or less.
5. Remove pail liner and dispose of properly.
6. Follow instructions in INSTALLATION section for refilling pail with
cleaning fluid.
for tempest 20S:
1. Open lower cabinet door. Unplug heater cord from lower socket in
outlet box located at right front of inside lower cabinet (Fig. 4, p.5).
If unit is equipped with an oil skimmer, also unplug its cord from the
adjacent outlet.
2. Remove drain and intake hose from reservoir. If unit is equipped
with oil skimmer, also remove oil skimmer discharge hose.
3. Roll reservoir out from the base and properly dispose of used
cleaning fluid.
4. If unit is equipped with an oil skimmer, remove excess oil from
exterior tramp collector.
A drain coupling has been provided in the reservoir. It is recommended
to plumb a drain valve to this coupling to facilitate cleaning.
Daily Maintenance
1. Check fluid level in cleaning solution reservoir daily. Assure level
is at or above minimum level at all times. Heavy, constant use may
warrant daily fluid changes.
2. Inspect filter bag on end of drain pipe daily. Filter bag is secured
to drain pipe with a reusable plastic tie – there is a small plastic
release lever on locking cube (Fig. 7, p.5). Properly dispose of any
solid waste accumulation, rinse bag in water, and re-attach to drain
pipe.
failure to keep cleaning solution reservoir full can result in heater
failure, loss of pump prime, or over heating of the fluid.
do Not operate unit without a filter bag.
Do NOT neglect cleaning of the heating element. Inspect heating
element daily. Any foreign material should be removed by gently
scrubbing. Failure to do so will cause premature failure. Do NOT allow
oil or sludge to bake onto the heater element as premature heater
burnout will result.
Weekly Maintenance
1. Check hoses weekly for wear and potential failure. Keep hose
connections tightened.
2. Check nozzle for blockage and keep free of debris.
3. Inspect filter bag.
Should hoses become loose, cracked or damaged in any way, they
should be replaced immediately as personal injury or damage could
occur to the unit.
failure to keep hose connections tight can result in loss of pump prime.
do Not allow pump to run dry. running dry for more than 30 seconds
can produce overheating and is harmful to the pump’s bearing and
piston seals.
loose drain pipe connections can cause leakage onto reservoir lid
which could damage lid or create an electrical shock hazard.
As Necessary:
1. Should viewing window become soiled, clean with white vinegar.
Excessive alkaline build-up will necessitate window replacement.
2. To prevent corrosive effects of detergent accumulation, it is
recommended that painted surfaces always be kept clean.
Pump Lubrication
Pump motor bearings are permanently lubricated.
Lubricate pump bearings with Moly-Lithium No. 2 grease (wheel
bearing grease) every 100 hours of operations or monthly.
Use a push type operated grease gun, if available. If using a lever
operated gun, work lever very slowly to prevent damaging bearing
seals. Very little grease is required.
do Not use an air-powered grease gun. it develops too much pressure
and will blow out bearing grease seals. the pump cavity should always
be clear of excess grease for proper heat dissipation. wipe out excess
grease; do Not wash out.
