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.
