TROUBLE SHOOTING (Cont'd.)
TROUBLE
CAUSE
REMEDY
A-6
Leaks in urn body other than
at fittings.
A-6
Pin holes or cracking of metal
due to insulation action of lime
or other abuse of urn.
A-6
Body leaks are best repaired at the factory. If soldering is attempted
in the field, metal must be thoroughly cleaned. Use only a flux made
specially for stainless steel and then neutralize completely. DO NOT
WELD OR BRAZE ! ! !
A-7
Water leaks or sprays out
through top of urn.
A-7.1
Water compartment overfilled through
oversight or because of leaky water
inlet valve.
A-7.1
Draw off excess water from water compartment by opening hot
water faucet. Never fill to a level higher than uppermost mark on
water gauge glass. Water expands with heat and can cause an
overfilled condition. To check whether overflowing is due to leaking
water inlet valve, proceed as follows: Shut off heating unit to urn.
(Check cannot be made accurately if water is boiling.) Close water
inlet valve firmly and note accurately water level in gauge glass. If
water level rises after a period of time, a leaky water inlet valve is
indicated. Remove valve bonnet, unscrew stem and install new
valve disc.
A-7.2
Excessive heat is applied to urn. This
is a rare cause, and is usually due to
excessive steam pressure in steam
heated urns, or an improperly
adjusted electric thermostat in
electrically heated urns.
A-7.2
If steam pressure is considerably in excess of that for
which urn was ordered, install reducing valve to cut
pressure down to that recommended for urn. Or, control
heat, input by fuel control valve. On electric urns, adjust
thermostat as shown on page 5.
B FILTERING AND BREWING
B-1
Filtering through Tri-Saver
is slow.
B-1. 1
Too fine grind prevents normal filtration.
B-1. 1
Have coffee supplier match sample grind packed with Tri-Saver
filter. If sample is lost, write factory for another.
B-1. 2
Filter clogged because not cleaned
regularly and according to instructions.
Extenders in coffee may also cause
clogging.
B-1. 2
Follow instructions on plate attached to Tri-Saver filter, or see page
8. Clogged filter can be cleaned by soaking overnight or several
nights in water with a good detergent. Avoid using coffees with
extenders as it may not be possible to dean these out.
10 LSQ
B-1. 3
Soft water used.
B-1. 3
Water may be "conditioned" but not softened. Slows up leeching
and destroys coffee taste.
