Preoperational Tests - Continental Girbau CG20 Installation Manual

I. PREOPERATIONAL TESTS
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or
due to marginal location (installation) conditions.
1. Turn on electric power to the dryer.
2. Refer to the Operating Instructions for starting your particular model dryer.
3. GAS MODELS ONLY
a. When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition
attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air
to be purged from the lines.
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
NOTE: Gas model dryers are equipped with an ignition system, which has internal diagnostics. If
ignition is not established after the one (1) time, the heat circuit in the ignition module will
attempt two (2) more ignitions (total of three [3] ignition attempts). If there is no flame after
the third ignition attempt, the module will lockout until it is manually reset. To reset the ignition
system, open and close the main door and restart the dryer.
IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be
regulated at the source (L.P. tank), or an external regulator must be added to each
dryer.
4. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit Thermostats
c. Cycling Thermostat
d. GAS AND ELECTRIC MODELS ONLY - Sail Switch
NOTE: The sail switch can be checked for proper operation by opening the lint door while heating
circuit (gas burner/electric oven) is active (on). The heating unit should shut off within a few
seconds. If not, make necessary adjustments to the sail switch.
5. Make a complete operational check of ALL operating controls.
NOTE: If computer program changes are required, refer to the computer programming section of the
manual supplied with the dryer.
6. The dryer should be operated through one (1) complete cycle to assure that ALL components are functioning
properly.
