INSTRUCTIONS

READ AND FOLLOW ALL INSTRUCTIONS

GENERAL:

Our shipping container has been specifically

designed to prevent transit damage.However, any

indications of damage should be carefully noted on

the delivery ticket and a claim filed promptly with the

carrier.

LOCATION:

Locate the pump as close as possible to the pool.

Provide the necessary space around the pump for

future inspection and servicing of the unit. If possible,

allow several inches of clearance below the motor to

floor to allow easy access to mounting screw. Locate

away from pool chemicals to prevent spilling on or

near motor.

INSTALLATION:

The pump suction line should not be smaller than

the pipe size on the inlet of the pump.

Your pump is made of the finest engineering

materials available today. A few simple precautions

taken during the initial installation, will insure many

long years of trouble-free operation.

The threads of pipe fittings screwed into pump

must be sealed with: pipe sealant, Teflon®Tape,

R.T.V.or other sealing materials approved for pipe

threads.

Tighten the pump fitting only as much as is

required to insure a tight connection. DO NOT OVER

TIGHTEN.

The piping should be supported independently

and not supported by the pump.

The pump motor must be wired for the proper

voltage, and rotation, in accordance with the wiring

diagram supplied with the motor.All wiring should be

done by a licensed electrician in accordance with

local codes, be certain that the motor frame is

grounded. Use lug on top of motor frame to bond

together motor and all metallic parts of pool, spa or

hot tub structure and to all electrical equipment,

metal conduit, and metal piping within 5 feet of the

inside walls of a swimming pool, spa or hot tub, when

the motor is installed within 5 feet of the inside walls

of the swimming pool, spa or hot tub structure with a

solid copper conductor not less than No.8 A.W.G.

Motor name plate has voltage, phase, ampere

draw and other motor information. Terminal cover

plate or name plate has wiring connection informa-

tion.

The wiring to motor should be kept as short as

possible and large enough to carry the necessary

current for required length without excessive voltage

drop.The following table should be followed to be

sure that the proper wire size is selected. Use as a

guide only.

TABLE OF A.W.G. WIRE SIZE

FOR

SINGLE-PHASE POOL PUMP MOTORS

WARNING - To reduce the risk of injury, do not

permit children to use this product unless they are

closely supervised at all times.

PRIMING:

Fill the pump pot with water before starting the

pump.This may be done by removing clear lid.

Pumps are self priming providing the pump pot is

filled with water.Should you lose this liquid from the

pot accidentally or by draining purposely, it will be

necessary to refill it with liquid before starting. High

Suction Lifts, require additional time for priming.

OPERATION:

After the pump has been filled with water, and the

motor started, allow a few moments for the pump to

start pumping water.If flow does not start within four

minutes, stop motor and refer to (THE TROUBLE

GUIDE). Be sure all suction and discharge valves are

open when the pump is running. Operating the pump

with a closed valve in the system can cause pump

damage.

WINTERIZING:

In areas subject to freezing winter temperatures,

protect pump by removing both drain plugs, one from

the pump volute and one from the pot. Do Not

Replace Plugs, store them in strainer basket for the

winter.

An alternate is to remove the pump and motor

from plumbing and store them indoors in a warm, dry

location.

MAINTENANCE:

The strainer basket in pump should be inspected

and cleaned twice each week. The strainer basket is

easy to clean. Loosen the knobs and remove the

clear lid. Remove the basket and clean. Inspect the

Lid “O”-Ring; if damaged, replace.Install the Clear

Lid, tightening knobs by hand only.The pump seal

requires no lubrication. Refer to motor service center

for motors.

WARNING: NEVER WORK ON PUMP WHILE IT IS RUNNING OR POWER IS STILL CONNECTED.

SPECIAL INSTRUCTION FOR TWO

SPEED ENERGY MASTER HYDROPUMP:

The performance of this pump will be the same at

high speed as the same model single speed pump,

both hydraulically and prime wise.At low speed the

pump will produce one half the flow and the pressure

will drop GREATLYwhich is due to much lower sys-

tem friction. These lower friction losses result in

GREAT energy savings.On low speed the electrical

energy savings are 60%.

Turn motor to high speed for vacuuming the pool,

reading the pressure gauge to determine if cleaning

or back washing of filter is required, for fast clean-up

of pool water, and for priming the system to rid it of all

air. Turn motor to low speed for quiet operation and

electrical cost savings.Since the pump should be

operated mostly at low speed for cost savings, minor

adjustments may be required in the automatic chlo-

rine dispenser, the skimmers and the heater due to

the lower flow. (See the equipment manufacturers

operation manuals).

All electrical work MUST be done by a licensed

electrician. Before working on motors be certain that

the electrical power is OFF at the main junction

box. TWO SPEED pumps have SINGLE VOLTAGE

motors which cannot be changed. See the motor

nameplate for the motor being installed. ALL electri-

cal connections should be made in the SIDE BOX

which also includes a prewired HI-LO switch. See

Diagram 1.

If an automatic timer is installed to change

speeds, the wiring connected to the switch should be

removed and the BLACK wire discarded. See

Diagram 2. The timer should then be installed and

connected to the motor as follows:

TIMER INSTALLATION FOR HI-LO SWITCHING

OF 2 SPEED HYDROPUMP®

An intermatic timer with single pole, double throw

switch may be used to automatically switch the

HYDROPUMP®between the high and low speed

modes at present intervals.

1) Check to see that timer voltage is the same as

that of the HYDROPUMP®motor.The following

intermatic timers should be used.

Hydropump H.P. Voltage Timer Model

3/4 115 T175*

1, 1 1/2, 2 230 T176*

*These models have skip-a-day wheel. Remove skip

screws if not needed.

2) Connect the timer to the motor following Diagram

3. All electrical connections to the motor should

be made in the side box.

NOTE: When time switch is ON - pump is on HI.

When time switch is OFF - pump is on LO.

CAUTION: Manual switch on motor side box must be

disconnected when HYDROPUMP®is being con-

trolled by the timer or the motor will be damaged.

TIMER INSTALLATION FOR PROGRAMMED

ON-OFF,HI-LO SWITCHING OF 2 SPEED

HYDROPUMP®

Automatic on-off and hi speed-lo speed control of

the ENERGYMASTER 2 speed pump can be

obtained by properly installing two appropriate

timers.One timer must have a single-pole, double

throw switch and the other must have a single-pole,

single throw switch. Both timers and the HYDRO-

PUMP®motor must be designed to operate on the

same voltage.

Only Intermatic timers are discussed below, but

other types may be used if desired. The following

timers are recommended for this installation:

Intermatic

Hydropump Timer Model No.

H.P. Voltage S.P.D.T. S.P.S.T.

3/4 115 T175* T101

1, 1 1/2, 2 230 T176* T102

•These models have skip-a-day wheel. Remove skip

screws if not needed.

1) Mount the timers side by side, between the power

supply and the HYDRO-PUMP®an Intermatic 2-

in-1 raintight case is ideal for this installation.

2) Timer No.1 will be used to control the hi speed-

lo speed switching of the motor.

3) Timer No.2 will be used to automatically switch

the HYDRO-PUMP®on and off.

The clocks of both timers must run continuously

for the proper operation of the switching circuits.

Therefore it is necessary to make a connection

between line 1 and the clock input of timer No.1. (See

Diagram 4.)

NOTE: When time switch 1 is ON - pump is on HI.

When time switch 1 is OFF - pump is on LO.

All wiring connections should be made with 12

A.W.G. or larger wire size.All wiring connections to

the HYDRO-PUMP®should be made inside the

motor side box. The 2 speed motor is designed to

operate on the voltage stamped on the nameplate

only.Wiring with a different line voltage will damage

the motor.

OPERATING INSTRUCTIONS

1) Set both clock dials to the exact time of day.

2) Locate the trippers on the clock dial of timer No.

2 to switch the HYDRO-PUMP®on and off at the

desired times.

3) Locate the trippers on the clock dial of timer No.

1 to switch the HYDRO-PUMP®between hi and

lo speed at the desired time.The timers should

always be programmed so that the HYDRO-

PUMP®will always operate for 10 minutes mini-

mum at hi speed when it is switched on. This

allows priming of the pump and evacuation of air

from the piping system.

4) The pump may be manually switched between hi

and lo speed by flipping the manual lever of timer

No.1, and may be switched on and off by flipping

the manual lever of timer No.2.

CAUTION: Always turn power off at main panel

before servicing switches or pumps.

CAUTION: Be certain the wiring CANNOTallow both

the HI and LO speed motor windings to be energized

at the same time.

CAUTION: This pump is for use with permanently

installed pools and may also be used with hot tubs

and spas if so marked. Do not use with storable

pools.A permanently installed pool is constructed in

or on the ground or in a building such that it cannot

be readily disassembled for storage.A storable pool

is constructed so that it may be readily disassembled

for storage and reassembled to its original integrity

and has a maximum dimension of 18 feet and a max-

imum wall height of 42 inches.

Do not install within an outer enclosure or

beneath the skirt of a hot tub or spa unless so

marked.

4 5

The Hydropump has an open face impeller

which was precisely set at the factory. Under

normal operating conditions it is not necessary

to make further adjustment, however, if the

pump draws excessive current a slight adjust-

ment may be required.

Loose the shaft extension set screws and

this will allow the mechanical seal spring to

force the impeller face to touch the volute.Place

a screwdriver between the motor bracket and

the shaft extension as depicted below. Move the

screwdriver handle away from the motor, this

will pull the impeller away from the volute. You

should move the shaft extension about 1/32”

and holding the screwdriver at this position firm-

ly tighten the shaft extension set screws.

Start the pump and check the amperage

draw. If the amperage exceeds the nameplate

rating or if the pump performs poorly the adjust-

ment needs to be redone.
