PUMP APPLICATION
WARNING
The Balboa Hydromassage pumps have been specifically
designed for use in spa baths (whirlpools). They should
not be used for any other purpose without first consulting
your Balboa dealer or Balboa representative.
The Balboa Hydromassage pump is NOT a self priming
pump. Ensure there is sufficient water to completely
fill the pump casing (flood suction) before operating
the pump.
PUMP POSITION
WARNING
To avoid water damage to property from leaking
connections or normal wear, the pump must be installed
on a well drained site or a properly constructed drain tray.
If the pump is supplied separately to the spa bath,
position the pump as close as possible to the spa. This
will ensure optimum spa jet performance.
PUMP INSTALLATION
The pump mount must be Solid – Level – Rigid –
t
Vibration free (to reduce vibration and pipe stress,
bolt the pump to the pump mount).
Install the pump suction inlet higher than bath suction
t
fitting (refer to Fig 1). This allows the pump to drain
completely when the bath is emptied in accordance
with Local Health Regulations.
Ensure suction pipe has an even rise from the spa
t
bath (whirlpool spa) suction inlet to avoid air locks,
otherwise the spa pump may not prime, Fig. 1.
Ensure discharge pipe has an even rise from the
t
pump to the spa bath (whirlpool) connection to avoid
air locks.
Protect pump from excess moisture, external weather
t
(where applicable).
Allow adequate access for servicing pump
t
and piping.
VENTILATION
Provide adequate ventilation to prevent the motor
t
from overheating (minimum distance is 102 cm).
Without adequate ventilation the pump motor may
overheat causing the pump to stop.
The hydromassage pumps must be protected from
t
exposure to the weather. If the pump is installed
outside, a protective cover is required.
PIPING
WARNING
The fittings on these hydromassage pumps are
constructed of ABS. Some PVC jointing compounds are
incompatible with ABS possibly causing failure to the
product. Check compound suitability prior to use.
For best pump efficiency use the least amount
t
of fittings.
Balboa hydromassage pumps are supplied complete
t
with integrated multi-directional (40mm) barrel unions
to allow easy installation of pipework. Use as follows
for leak-free connections to pump:
O-Ring and sealing surfaces must be clean.
1.
Ensure O’Ring remains on barrel unions and tighten
2.
HAND TIGHT only! (NO WRENCHES)
No pipe compound or teflon tape on unions.
3.
Bond pipe to unions with a compatible PVC
4.
solvent cement.
When appropriate, fill the bath with water and check
5.
that there are no visible leaks from the plumbing
joints. Start the pump and repeat this step.
AIR BLEED VALVE
Air bleed valves are sometimes required on installations
so that automatic air venting can occur.
Balboa 200 Series Hydromassage pumps are fitted with
an air bleed valve. If the pump is installed exactly per Fig.
1, this valve will not be required to be made functional
(the air bleed valves are sealed at the manufacturer).
If automatic air venting is required, cut the top of the
valve off at the cut groove found approximately 3.5mm
from top of the valve per Fig. 2 using a pair of side
cutters. DO NOT USE PLIERS. The air bleed valve will not
expel air.
As it is common for air valves to squirt water when sealing
(each time the pump is turned on), Balboa recommends
that a 10mm drain tube to be fitted over the barbed
section of the air bleed valve to allow excess water to
drain to waste. Refer to Fig. 2.
