INTRODUCTION
The SpaPak Spa Heaters have been designed to provide efficient, pollution-free, electric pool heatin
g while requiring minimal installation. The SpaPak consists of sheathed resistance element installed in a copper tank.This tank has a 1-1/2” inlet and outlet on the side for plumbing connections. The heater voltage is 208/240V single-pha. The control circuit pass through a manual switch, the temperature control, and the mag-netic contactor coil. All items are pre-wired and installed in a baked enamel steel ca.
FOREWORD
It is esntial that the spa heater be installed in accordance with the instructions given herein. Failure to do so may cau damage to the spa heater and to the equipment to which it is connected, or may prevent the spa heater from operating in a correct manner. The heater is to be installed in accordance with article 680 of the National Electrical Code ANSI/NFPA No. 70. Consult State and Municipal Codes BEFORE installing this unit.Where such codes have requirements beyond the in-structions given herein, the codes shall have precedence over the instructions.
LOCATION
The heaters are listed by UL for either indoor or outdoor u. Unit must be mounted on a level ba parallel to the ground. Allow 6” clearance at sides and 18”clearance at top and front for mainte
nance. Secure the unit with 5/16” mounting hardware using the holes pro-vided. The heater must be located where leakage of heat exchanger or connections will not damage the area adjacent to the heater or structure.WATER CONNECTIONS -PVC Pipe May Be Ud
ELECTRIC SPA-PAK HEATER
INSTALLATION & OPERATING INSTRUCTIONS
The SpaPak has 1-1/2” male NPT inlet and outlet connections at the right side of the heater. The inlet is at the ba of the heater and must be piped directly to the filter discharge to assure proper flow direction. Minimum flow rate through the heater is 15 GPM, maximum is 60GPM. If this is exceeded, an external bypass must be added as shown. Unions should be ud on piping connections. A shut-off valve should be included on the heater inlet to prevent draining the spa for maintenance.CAUTION: No shut-off valves are to be installed in the piping between the heater outlet and the spa. Any chlorinators, valves, etc., that can cau return line blockage will void the warranty.
AUTOMATIC CHLORINATORS AND CHEMICAL FEEDERS
All chemicals must be introduced and completely diluted into the spa water before being circulated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concentrations will result when the pump is not running (e.g. overnight).
Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical back-up into the heater when the pump is shut off.
NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cau very rapid corrosion to the heater. Such damage is not covered under the warranty.

ELECTRICAL
WARNING: The power supply circuit to this heater shall be protected by a ground-fault circuit interrupter (GFCI),in accordance with Art. 680 of the latest edition of the National Electrical Code (NEC). Failure to do so could result in vere personal injury or death.
The GFCI devices shall be of the lf-contained types,circuit breaker types or the receptacle types. Feeder ground-fault protection is not required where GFCI is already provided in the branch circuits or receptacles supplying power to the heater.
ELECTRICAL DISCONNECT
An electrical disconnect and over-current protection device must be provided in accordance with local codes.Keep wire runs as short as possible to minimize voltage drop. Bring wires of size indicated from a fud discon-nect switch (customer furnished) with an amperes rating of at least 125% of the ampere rating shown on the spa heater nameplate. A ground lug is provided for connec-tion to the supply ground. A wiring diagram of the interior of the heater is shown at right. It is also affixed to the inside front cover of the units.
FIELD WIRING
Heater requires three-wire rvice. With 240 VAC
there are two hot wires and a grounding conductor. Even though metallic conduit is ud, the grounding conductor must be run to the supply ground.
Field wiring connections are made to the electrical entry at the left side of the unit. A hole in the jacket is provided for a 1” trade size conduit hub. The location of the field wiring box is shown below. Wire nuts are ud to connect all leads except the grounding conductor, for which a pressure lug is provided.
NOTE: Heater grounding conductor shall be the same or larger than the live power supply conductor.
RECOMMENDED WIRE SIZES FOR FIELD CONNECTION
U type THW copper wire to the unit, with the following AWG Wire sizes: (Internal wire sizes may differ)
*U a reducer bushing.
CONTROLS
ELS spa heaters have integral thermostats and
contactors. They are also equipped with a high tempera-ture limit thermostat which will open the circuit cutting off power to the heating element in the event of excessive heat temperature. This high limit thermostat is factory t at 140°F. A pressure switch is utilized to assure water flow through the heater before the unit will function.

NOTE: The filter must be kept clean so the flow rate will be maintained above 15 GPM. Failure to do so will cau the pressure switch to drop out, and the heater will become inoperative.
OPERATION
PRELIMINARY
MAKE SURE THAT POWER TO THE UNIT IS OFF. Remove any tools or other foreign objects from the inside of the unit. Replace the removable lower panel. Place temperature control in the off position. Check tightness of electrical screw terminals.
FILLING
Open all valves in the inlet piping and fill the system with water. Turn on the filter pump and purge all air from the
system. On in-ground spa installations it may be neces-sary to prime the pump. Check the unit and all piping connections for leaks.
START-UP - FILTER PUMP MUST BE ON FOR THE HEATER TO OPERATE
Turn on the main power to the unit, then t the temperature control to the desired position and turn the switch to the “ON” position to place the spa heater in operation. Shut pump off and on to be certain that heater shuts off when pump is off.
A thermal cutout prevents the unit from overheating. Should overheating occur, the control circuit may be made operational by depressing the manual ret button on the front panel. This will be possible only after the unit has cooled down for veral minutes.

IMPORTANT SAFETY INSTRUCTIONS
CAUTION:Elevated water temperature can be hazard-ous, and the U.S. Consumer Product Safety Commis-sion recommends the following guidelines:
When using this electrical equipment, basic safety precautions should always be followed, including the following:
1.READ AND FOLLOW ALL INSTRUCTIONS.
2.To reduce the risk of injury:
A.The water in a pool or tub should never exceed
104°F (40°C). A water temperature in excess of
104°F is considered unsafe for all persons. Lower
water temperatures are recommended for extended
u (exceeding 10 – 15 minutes) and for
young children.
B.Since excessive water temperatures have a
high potential for causing fetal damage during the
early months of pregnancy, pregnant or possibly
pregnant women should limit pool or tub water
temperatures to 100°F (38°C)
C.Before entering a pool or tub, the ur should
measure the water temperature at veral occu-
pant locations using an accurate thermometer since
the tolerance of water temperature-regulating
devices may vary as much as ±5°F (±3°C).
D.Alcohol, drugs, or medication should not be
ud before or during pool or tub u since their u
may lead to unconsciousness with the possibility of
drowning.
E.Persons suffering from obesity or with a medi-
cal history of heart dia, low or high blood
pressure, circulatory system problems, or diabetes
should consult a physician before using a pool or
tub.
F.Persons using medication should consult a
physician before using a pool or tub since some
medication may induce drowsiness while other
medication may affect heart rate, blood pressure,
and circulation.
WARNING – The u of alcohol, drugs, or medication can greatly increa the risk of fatal hyperthermia in pools and tubs.
4NOTE:Hyperthermia occurs when the internal tempera-ture of the body reaches a level veral degrees above the normal body temperature of 98.6°F. The symptoms of hyperthermia include dizziness, fainting, drowsiness, lethargy, and an increa in the internal temperature of the body. The effects of hyperthermia include (1) un-awareness of impending hazard, (2) failure to perceive heat, (3) failure to recognize the need to exit pool or tub, (4) physical inability to exit pool or tub, (5) fetal damage in pregnant women, and (6) unconsciousness resulting in
a danger of drowning.
3. A green terminal (or wire connector marked "G",
"GR", "GROUND" or "GROUNDING") is provided
within the control box. To reduce the risk of electric shock, connect this terminal or connector to the
grounding terminal of the electric rvice or supply panel with a continuous copper wire in accordance with the Canadian Electrical Code, Part I.

SPA WATER CHEMISTRY
Chemical imbalance can cau vere damage to your heater and associated equipment. Maintain water pH between 7.4 and 7.8, and total alkalinity between 100 and 150 If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger, reducing heater efficiency and also damaging the heater. If the pH drops below 7.2, the heater will be verely damaged. This will result in corrosion of the heat exchanger. Heat exchanger damage resulting from chemical imbalance is not covered by the warranty. ELEMENT INSPECTION AND REPLACEMENT The element asmbly head is removed as
