WARNING: Live electrical
contacts are exposed, so dis-
connect power fi rst and have
work performed by a qualifi ed
electrician.
AVERTISSEMENT: Les con-
tacts électriques sous ten-
sion sont exposés, il faut
donc d'abord débrancher
l'alimentation électrique et confi er le travail à un
électricien qualifi é.
Remove cover of the pump pressure control switch to
allow access to the two nuts used to adjust the pump
operating pressure. The pressure switch on Water
Maze equipment is set at the factory and should not
have to be adjusted at start-up, but will need to be
verifi ed at start up and maintained regularly at least
monthly.
1. The nut on the larger spring in the pump pressure
switch, adjusts the pump cut in (cut on) and pump
cut out (cut off) pressures simultaneously.
2. The nut atop the smaller spring in the pump pres-
sure switch only controls the cut out range and
is used to narrow or widen the gap between the
pump cut in and cut out pressures.
3. To cycle the pump less frequently, the gap should
be as wide as possible while still allowing the
pump to shut off quickly when all outlets are
closed. Adjust the smaller spring to widen the
gap between pump in and out (on and off). 40-
45 PSI (CLP, Rec2-20) or 30 PSI (EC1-300A) is
desirable. Adjusting the larger spring should not
be necessary.
4. When making pressure switch adjustments, make
sure all pump outlets are off or closed, except for
the one outlet valve used to relieve and build pres-
sure while making pressure switch adjustments.
PRESSURE TANK
OPERATION
WARNING! When the tank has
been in service and a change
to a higher pre-charge pressure
is necessary because of a re-
quired change in the pressure
switch setting, failure to follow
instructions below can cause a
rupture or explosion and could
cause serious or fatal personal
injury and/or property damage.
AVERTISSEMENT: Après avoir effectué l'entretien
du réservoir, il est nécessaire de passer à une
pression de précharge supérieure en raison d'un
changement requis du paramètre du pressostat;
le non-respect des directives ci-dessous peut
causer une rupture ou une explosion, et pourrait
causer des lésions corporelles graves ou fatales
et/ou des dommages à la propriété.
• Do not adjust or add pressure if there has been a
loss of air.
• Do not adjust the pre-charge pressure if there is
visible exterior corrosion.
• Do not adjust the pre-charge pressure if there has
been a reduction of the pump cycle time or the
pre-charge pressure compared to its initial setting.
A reduction in pump cycle time can result from
loss of tank corrosion and any re-pressurization
or additional pressure could result in rupture or
explosion.
• Pressure tank pressure is factory set but will have
to be checked regularly (at least monthly). Use
an air pressure (tire) gauge. Before checking air
pressure on the pressure tank, purge all water out
of the tank by turning the pump on and pumping
all water out of the pressure tank.
1. Our transfer pump water systems use a water
pressure tank and water pump with these two
pressure operation ranges:
Cut in (start pumping): 20 PSI
Cut out (stop pumping): 30 PSI (EC1-300A)
Cut out (stop pumping): 40-45 PSI (CLP, REC2-20)
2. Typical factory set air pressure on bladder-type
residential water pressure tanks are shipped from
the factory with a standard pre-charge of:
18 psig for models WX-101 and WX-102
18 psig for models WX-103 and WX-203
18 psig for models WX-205 and WX-350
3. Set the well tank air pressure to 2 PSI below the
pump pressure switch cut-in pressure. This is
usually 18 PSI.
