General Information
2.1 Introduction
This manual contains information for the proper
installation, operation and maintenance of Jandy
HHPlus Pumps. Procedures in this manual must be
followed exactly. To obtain additional copies of this
manual contact us at 707-776-8200, ext. 237. For
address information see back cover.
2.2 Description
Jandy
HHPlus Pumps are designed to meet the
®
needs of today's more hydraulically demanding pool
equipment. The pump housing, seal plate, diffuser, hair
and lint pot (pump basket), and impeller are all made
from high quality thermoplastic materials. These
materials were chosen for their strength and corrosion
resistance.
The pump is driven by an electric motor directly
attached to the pump impeller. As the electric motor
turns it causes the impeller to turn which forces water
to flow through the pump. The water flows into the
hair/lint pot inlet and through the basket assembly. The
basket assembly will pre-strain large particles. The
flow then enters the center of the pump housing, goes
through the impeller, into the diffuser, and out the
pump discharge port.

Preparation and Location
3.1 Pump Preparation
3.1.1 Upon receipt of the pump, check for carton
damage. After opening the carton, check for
concealed damage such as cracks, dents or a
bent base. If damage is found contact the
shipper or distributor where the pump was
purchased.
3.1.2 Inspect for missing parts, unions, lid, or basket.
See the part lists on page 14.
3.2
Pump Location
3.2.1 The pump should not be elevated more than a
few feet above the water level of the pool, it is
best to locate the pump within one (1) foot of
the water level. A check valve is recommended
on the suction line to the pump.
3.2.2 If the pump is located below water level, valves
should be installed on both the suction and
return lines to prevent back flow of pool water
during any routine servicing that may be
required.
®
3.2.3 The pump and other circulation equipment
should be located a minimum of five (5) feet
from the water. Choose a location that will
minimize turns in the piping.
3.2.4 The pump must be placed on a solid foundation
that will not vibrate. To further reduce the
possibility of vibration noise the pump can be
bolted down, or placed on a rubber mat.
3.2.5 The pump foundation must have adequate
drainage to prevent the motor from getting wet.
Protect the pump from the rain and sun.
3.2.6 Proper ventilation is required for the pump to
operate normally. All motors generate heat that
must be removed by providing proper
ventilation.
3.2.7 Provide access for future service by leaving a
clear area around the pump. Allow plenty of
space above the pump to remove the lid and
basket for cleaning.
3.2.8 If the equipment is under cover, provide
adequate lighting.
SECTION 4.
Piping Design & Installation
4.1 Size of Suction Pipe
4.1.1 Recommended pipe size for the suction side of
the pump is 2" for ¾ to 1½ HP. For 2 HP pumps
recommended pipe size is 2½". For 3 HP pumps
recommended pipe size is 3".
4.2 Size of Discharge Pipe
4.2.1 Recommended pipe size for the discharge side
of the pump is 2" for ¾ to 2 HP. For 3 HP pumps
recommended pipe size is 2½".
Note: All pipe sizes are able to withstand the
pressures the pump will deliver, but not the flow.
If the pipe is too small for the pump, or it is
elevated above water, the maximum gallons per
minute (GPM) may not be delivered.
