SERVICE KITS
To ensure the correct service kit, order by the
complete model number, date of manufacture
and name plate data. Parts kits come with
complete repair instructions.
1. Switch/Check valve and Upper Housing Kit
(replaces all previous switch designs).
2. Valveplateassembly.
3. Diaphragm/Drive assembly.
4. Motor.
5. Complete Pump Head assembly (replaces
all previous switch designs).
least 13mm (½') ID. for main lines.
Restrictive fittings and connections
(elbows, ‘T’s’, feeder lines to taps, etc.)
SWITCH SHUT-OFF
Restrictions in a plumbing system may cause
thepumptorapidcycle(ON/OFFwithin2
seconds)duringlowowdemands.Cycling
should be minimized to prevent pulsating
ow,andtoachievemaximumpumplife.
To determine if adjustment is necessary, turn
tapontolowerthanaverageowofwater.
The pump should cycle, but its ‘OFF time’
must be 2 seconds or longer. If the cycling is
correct, leave well enough alone. If the pump
is cycling rapidly increase the setting by turning
the screw clockwise (1½, turn maximum)
until the pump operates for 1 second with at
least 2 seconds ‘OFF time’. If cycling cannot
be minimized consider removing plumbing
restrictions or install an accumulator.
SANITIZING
Fresh water systems require periodic
maintenancetodeliveraconsistentow
of fresh water. Depending on the use and
the environment the system is subject to,
sanitizing is recommended prior to storing
and before using the water system after
a period of storage. Systems with new
components, or ones that have been subjected
to contamination, should also be disinfected
as follows:
Use the following method to determine the
amount of common household bleach needed
to sanitize the tank.
1. Multiply ‘litres of tank capacity’ by 1; the
result is the millilitres of bleach needed to
sanitize the tank.
2. Mix into solution the proper amount of
bleach within a container of water.
3. Pour the solution (water/bleach) into the
tank and fill the tank with fresh water.
4. Open all taps (HOT & COLD) allowing the
water to run until the distinct odour of
chlorine is detected.
5. The standard solution must have four
hours of contact time to disinfect
completely. Doubling the solution
concentration allows for contact time of
one hour.
6. When the contact time is completed, drain
the tank. Refill with fresh water and purge
the plumbing of all sanitizing solution.
NOTE: The sanitizing procedure outlined
above is in conformance with the
approved procedures of RVIA ANSI A119.2
and the USA Public Health Service. It may
not be permitted or recommended in
certain countries.
WINTERISING
If water is allowed to freeze in the system,
serious damage to the plumbing and the pump
may occur. Failures of this type will void the
warranty. The best guarantee against damage
is to completely drain the water system.
However, non-toxic antifreeze for fresh water,
if available at local caravan centres, may be
used.
CAUTION: Do not use Automotive
Antifreeze to winterize drinking water
systems. Such solutions are highly toxic.
Ingestion may cause serious injury or
death. To properly drain the system
perform the following:
1. Drain the water tank. If the tank doesn’t
have a drain valve open all taps allowing
thepumptooperate(15min.ON,15min.
OFF) until the tank is empty.
2. Open all the taps (including the lowest
valve or drain in the plumbing) and allow
the pump to purge the water from the
plumbing, then turn the pump OFF
3. Using a pan to catch the remaining water,
remove the plumbing at the pump’s inlet/
outletports.TurnthepumpON,allowing
it to operate until the water is expelled.
Turn OFF power to the pump once the
plumbing is emptied. Do not reconnect
pump plumbing. Make a note at tank filler
as a reminder: ‘Plumbing is Disconnected’.
4. All taps must be left open to guard against
any damage.
