INTRODUCTION

The Spa-Pak spa Heaters have been designed to pro-

vide efficient, pollution-free, electric pool heating while

requiring minimal installation. The Spa-Pak consists of

a 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-phase. The control circuit passes 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 case.

It is essential that the heater be installed in accor-

dance with the instructions given herein. Failure to do

so may cause damage to the heater and to the equip-

ment to which it is connected, or may prevent the

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 local codes BEFORE installing this unit.

Where such codes have requirements beyond the

instructions given herein, the codes shall have prece-

dence over these instructions.

Location

These heaters are listed by UL for either indoor or out-

door use. Unit must be mounted on a level base

parallel to the ground. Allow 6” clearance at sides and

18” clearance at top and front for maintenance. Secure

the unit with 5/16” mounting hardware using the holes

provided. 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

The Spa-Pak has 1-1/2” male NPT inlet and outlet

connections at the right side of the heater. The inlet is

at the base of the heater and must be piped directly to

the filter discharge to ensure proper flow direction.

Minimum flow rate through the heater is 15 gpm, max-

imum is 60 gpm. If this is exceeded, an external

bypass must be added as shown. Unions should be

used on piping connections. A shut-off valve should be

included on the heater inlet to prevent draining the spa

when performing maintenance.

Automatic Chlorinators and

Chemical Feeders

All chemicals must be introduced and completely dilut-

ed 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

backup into the heater when the pump is shut off.

NOTE:

NOTE:

When using two speed pumps, do not install

gate valve on inlet.

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 cause return

line blockage will void the warranty.
