Lubrication and Maintenance
Intervals
Safe and reliable service from your Slide-
in Unit depends upon a regular schedule of
lubrication and maintenance. Figure 4.1
details the lubrication locations on your
slide-in unit. Tables 4.1 and 4.2 list
intervals for lubrication and maintenance.
In addition, the following sections detail the
required lubrication and maintenance for
individual components.
WARNING: before performing any
lubrication and maintenance, review and
follow the “SAFETY PRECAUTIONS” on
pages 5-7 and all safety precautions
listed below.
Moisture Trap / Secondary Shut Off
Check the moisture trap daily for collected
liquid. Use the easy access drain valve to
empty the trap. The drain is located at the
bottom of the moisture trap.
In addition to checking for liquid, inspect
the ball seat and the fasteners every 2
weeks.
Check all moisture trap fasteners and
tighten as necessary. Road vibration over
time can loosen fasteners.
Remove the moisture trap cover to
examine the ball seat for hardened rubber,
nicks in the rubber, and a buildup of debris.
Any of these conditions may prevent
proper sealing. Clean and/or replace the
ball seat as necessary.
Any time that excess liquid accumulates in
the moisture trap, clean the inside of your
pump. While the moisture trap helps
prevent liquid from entering the pump,
excess accumulation may be an indicator
that some contamination has passed into
the pump. Contaminates entering the
pump (including effluent) is a major cause
of pump failure. See page 26 for vacuum
pump cleaning procedure.
In addition, clean and/or replace the ball
seat in the primary shutoff any time that
excess liquid accumulates in the moisture
trap. Excessive liquid in the moisture trap
can often be traced to improper sealing of
the ball seat in the primary.
IMPORTANT:
A
ny time that excess
liquid accumulates in the moisture trap,
clean the inside of your pump. Liquid
contamination that enters the pump can
cause damage if you do not clean the
pump shortly thereafter.
Primary Shutoff
Inspect the primary shutoff every 2 weeks
to check the rubber ball seat and the
tightness of all fasteners.
To inspect the ball seat, begin by first
removing the cap screws that fasten the
primary shutoff access lid to the portal
flange on the tank (Figure 4.2). After the
fasteners are removed, lift the entire
shutoff assembly (which is fastened to the
access lid) out of the tank be careful not to
let the portal gasket fall on the ground or
into the tank.
Next, remove the cap screw at the
bottom of the float cage and reach up
through the cage tube to remove the
seat.
Next, remove the cap screw at the
bottom of the float cage and reach up
through the cage tube to remove the
seat.
Examine the ball seat for hardened
rubber, nicks in the rubber, and a buildup
of debris. Any of these conditions may
prevent proper sealing. Clean or replace
the seat as necessary
Reassemble the primary shutoff in the
reverse order. Be sure to tighten all
