If you have electrical power, check the following:

1.  The time clock must be moved to the "ON" posi-

tion.

2.  Your  pump  strainer  basket  may  be  full.  If  so

remove debris.

3.  Your filter may be dirty. If so, backwash or clean fil-

ter. (If your filter is dirty, the gauge pressure will be
higher than usual).

4.  The pump may have lost its prime and be running

dry. Check the pressure gauge on the filter. If there
is  no  pressure;  the  water  is  not  moving  (or  your
gauge is broken). Try to get the pump to run at its
normal flow rate.

Pool & Spa Water 

Chemistry

Chemical  imbalance  can  cause  severe  damage  to
your heater and associated equipment. Maintain your
water  chemistry  according  to  the  chart  on  page  5.  If
the mineral content and dissolved solids in the water
become  too  high,  scale  forms  inside  the  heat
exchanger tubes, reducing heater efficiency and also
damaging the heater. 

If the pH drops below 7.2, the heater will be severely
damaged.  This  will  result  in  corrosion  of  the  heat
exchanger.  Heat  exchanger  damage  resulting  from
chemical imbalance is not covered by the warranty.

Cold Weather Operation

Heater operation can continue during short term cold
spells.  When  temperatures  are  below  freezing,  flow
(continuous pump operation) must be maintained.

Prolonged  operation  with  water  temperatures  below
50°F  is  not  recommended.  When  starting  the  heater
with pool temperatures below 50°F, operate the heater
continuously  until  higher  temperatures  are  reached.
Operating the heater for prolonged periods with pool

water  below  50°F  can  seriously  damage  the  heater,
and will void the warranty.

For  cold  climate  areas  please  follow  the  winterizing
procedures listed below.

Winterizing the Spa Heater

When  heaters  installed  outdoors  in  freezing  climate
areas are to be shut down for the winter, observe the
following procedure:

1.  Turn off gas valve, manual gas valve, and electri-

cal supply to the heater.

2.  Open drain cock located on the return header.

3.  Disconnect compression fittings from the pressure

switch and header that connect to the 1/4" copper
tube and allow the tube to drain.

INTRODUCTION

Receiving Equipment

On receipt of your equipment it is suggested that you
visually check for external damage to the carton. If the
carton is damaged, a note should be made on the Bill
of  Lading  when  signing  for  the  equipment.  Remove
the heater from the carton and if it is damaged, report
the damage to the carrier immediately.

On occasion, we ship some items loose. Be sure that
you receive the number of packages indicated on the
Bill of Lading.

When  ordering  parts,  you  must  specify  model  and
serial number of heater. When ordering under warran-
ty  conditions,  you  must  also  specify  the  date  of
installation.

The  manufacturer  recommends  that  this  manual  be
reviewed  thoroughly  before  installing  your  pool/spa
heater.  If  there  are  any  questions  that  this  manual
does  not  answer,  please  contact  the  factory  or  your
local representative.

CAUTION:

Do not use the heater to maintain water

temperatures  just  above  freezing,  or  for  freeze
protection.  When  heaters  are  used  during  freezing
weather,  care  must  be  taken  to  avoid  freeze-ups.
Continuous  pump  operation  is  a  must.  Additional
protection  may  be  required.  The  heater  is  not
warranted against freeze-ups.
