Safety Check; Turn On Power; Initiate Water Circulation; Add Start-Up Chemicals - Sundance Spas 780 Owner's Manual

may fill entirely with hard water if you use a special water additive available
from your Sundance dealer. Always refill with garden hose in filter
compartment. This helps to purge trapped air from pump intakes. Failure
to do so may cause air to be trapped in either pump 1 or the circulation
pump's intake (air lock), preventing either pump from circulating water.
After filling, make sure the filter is installed properly before applying power
to the spa. Refer to section 1 1.1 (Page 20-21) "Cleaning the Filter" for
specific cleaning and installation instructions.

7.2 Safety Check

Open the cabinet access panel and check all pump unions to make sure they
are hand tight. Loosening can occur during shipping and handling.

7.3 Turn on Power

Turn on power to spa at the home's circuit breaker. The heater and low speed
pump 1 automatically activate and the control panel LED display flashes water
temperature and "COL" or "ICE" (page 29).

7.4 Initiate Water Circulation

Depress the JETS 1 sensor pad on the control panel twice to
activate pump 1 in high speed and initiate maximum water flow
to certain jets.

7.5 Add Start-Up Chemicals

Add the spa water chemicals as recommended by your Sundance dealer.
Refer to section 1 2.0-1 2.3 (page 26-27) for general guidance.

7.6 Place Cover On Spa

Keeping the insulating cover in place anytime the spa is not in use will
reduce the time required for heating, thereby minimizing operating costs.
The time required for initial heat-up will vary depending on the starting water
temperature and the capacity of your spa. Smaller spas heat at a rate of
approximately 8 to 10 degrees per hour (based on 240V operation); large
spas heat at about 4 to 6 degrees per hour.
WARNING: RISK OF INJURY. Always check water temperature
carefully before entering spa.
