Introduction

Section 2. Introduction

P/N 474131 Rev. D 27-06-11

CONSUMER INFORMATION AND SAFETY

WARNING

The U.S. Consumer Product Safety Commission warns that carbon monoxide is an "invisible killer". Carbon monoxide

is a colorless and odorless gas.

1. Carbon monoxide is produced by burning fuel, including natural gas and propane.

2. Proper installation, operation and maintenance of fuel-burning appliances in the home is the most important factor in reducing

carbon monoxide poisoning.

3. Be sure that fuel burning appliances such as heaters are installed by professionals according to manufacturer's instructions and codes.

4. Always follow the manufacturer's directions for safe operation.

5. Have the heating system (including vents) inspected and serviced annually by a trained service technician.

6. Examine vents regularly for improper connections, visible cracks, rust or stains.

7. Install battery-operated carbon monoxide alarms. The alarms should be certified to the requirements of the most recent UL, IAS,

CSA and IAPMO standard for carbon monoxide alarms. Test carbon monoxide alarms regularly and replace dead batteries.

WARNING

The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous.

See below for water temperature guidelines before setting temperature.

1. Spa or hot tub water temperatures should never exceed 40° C. A temperature of 37° C. is considered safe for a healthy adult.

Special caution is suggested for young children. Prolonged immersion in hot water can induce hyperthermia.

2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness

and subsequently result in drowning.

3. Pregnant women beware! Soaking in water above 37° C. can cause fetal damage during the first three months of pregnancy

(resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick to the 37° C. maximum rule.

4. Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer. Spa or hot tub

thermostats may err in regulating water temperatures by as much as -15° C.

5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their

physician's advice before using spas or hot tubs.

6. Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use spas

or hot tubs.

injury. Do not allow children to play on or around heater or associated equipment.

WARNING —

Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly

when installing heater. Do not use a drafthood with this heater, as the exhaust is under

pressure from the burner blower and a draft hood will allow exhaust fumes to blow into the room

housing the heater. The heater is supplied with an integral venting system for outdoor installation.

CAUTION —

Label all wires prior to disconnection when servicing controls. Wiring errors can cause

improper and dangerous operation. Wiring errors can also destroy the control board.

• Connect heater to 240 Volt, 50 Hz., Single Phase power only.

THIS PRODUCT MUST BE INSTALLED AND SERVICED BY A PROFESSIONAL SERVICE TECHNICIAN, QUALIFIED IN POOL

HEATER INSTALLATION.

Pentair strongly recommends that all vents, pipes and exhaust systems be initially and periodically tested for proper operation. This

testing can be accomplished by using a hand-held carbon monoxide meter and/or by consulting with a gas professional.

Pool heaters must be used in conjunction with carbon monoxide detectors installed near the pool heater. The carbon monoxide

detectors must be periodically inspected for proper operation so as to insure continued safety. Broken or malfunctioning carbon

monoxide detectors must be replaced immediately.

HEATER DESCRIPTION

Figure 1 is a diagram of the heater showing how it operates. Precisely

matched orifice plates meter the air and gas into the mixer. The blower

draws the air and gas through the mixer and forces it into the burner’s

flame holder. A sealed heat exchanger surrounds the flame holder,

discharging exhaust gases out the flue.

Five (5) cm PVC water piping connects directly to the manifold/

header on the heat exchanger using 5 cm PVC slip unions provided

with the heater. The outer manifold remains cool; no heat sinks are

required. A thermal regulator and an internal bypass regulate the water

flow through the heat exchanger to maintain the correct outlet

temperature. The heater operator control panel board assembly is

located on top of the heater.

SEQUENCE OF OPERATION

An electronic temperature sensing thermistor in the manifold adapter inlet controls the heater operation. When the inlet

water temperature drops below the temperature set on the operating control, the burner controller supplies power to

the combustion air blower through a series of safety interlocks. The interlocks consist of:

• the pressure switch (PS), which senses that the pump is running,

• the high limit switch (HLS), which opens if the heat exchanger outlet temperature goes above 53° C (127° F), and

• the air flow switch (AFS), which senses the pressure drop across the air metering orifice,

• the automatic gas shut-off (AGS) switch, which opens if the heat exchanger outlet temperature goes above 60° C (140° F).

• the stack flue sensor (SFS), which shuts down the heater if the flue gas temperature reaches 249° C (480° F).

The air flow switch (AFS) senses the pressure drop across the air metering orifice. As soon as there is sufficient air flow,

the AFS closes, closing the circuit to the hot surface igniter (HSI), which ignites the fuel mixture. On a call for heat, the

blower and HSI are energized. In about 20 seconds, the gas valve opens and ignition occurs. The HSI then switches to a

sensing mode and monitors the flame.

The heater is equipped with a digital operating control that enables the user to pre-set the desired pool and spa water

temperatures. The control enables the user to select between pool and spa heating, and features a digital display that

indicates the water temperature.

PUTTINGTHE HEATER INTO SERVICE

If the heater is installed below the level of the pool, or more than 0.6 meters (2 feet) above pool level, the pressure switch

setting should be adjusted. See “WATER PRESSURE SWITCH” in the “SAFETY CONTROLS Section” (page 32) and

the “CAUTION” under “BELOW POOL INSTALLATION Section” (page 12).

Before putting the heater into service for the first time, follow the instructions under “BEFORE START-UP” (page 30) in

the front of this manual. Check for proper operation of the heater by following the steps under “OPERATION

INSTRUCTIONS.”

Damage to equipment caused by improper installation or repair will void the warranty.

P/N 474131 Rev. D 27-06-11

Section 3. Installation
