VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

SERVICE PROCEDURES AND ADJUSTMENTS

WARNING: CERTAIN PROCEDURES IN THIS SECTION REQUIRES ELECTRICAL TEST OR MEASUREMENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER, ATTACH TEST EQUIPMENT AND REAPPLY POWER TO TEST.

BOILER

Inspection

It is recommended the boiler be inspected for excessive scale and lime build up on a quarterly basis. In hard water areas or for steamers heavily used, a more frequent interval should be used. This inspection consists of an internal examination and cleaning of the boiler, an examination of the two hanging descalers, and for lime build up on the water level probes. Also, a check of all boiler controls, including the pressure switches.

Periodic service must be performed as outlined in these procedures. See “WATER CONDITIONING” under “GENERAL”.

WARNING: READ AND FOLLOW THE INSTRUCTIONS ON THE CLR BOTTLE. USE PLASTIC OR RUBBER GLOVES TO AVOID SKIN CONTACT. IF CLR LIQUID COMES IN CONTACT WITH THE SKIN, RINSE WITH CLEAN WATER.

Clean-Out (All Boiler Models)

1.Turn steamer OFF and drain boiler.

2.Remove hand hole plate and gasket (top front) from the boiler by removing the nut and clamp, then tapping the cover lightly to free it while holding the cover stud. This prevents the cover from dropping into boiler.

3.Remove old descaler retaining springs if present.

4.With a wire brush, or equivalent, dislodge and remove all loose scale from boiler shell. The loose material must be either scooped from the boiler or flushed through the drain.

5.Check probe canister and float valve assembly (regenerated models) for a scale build up and clean as necessary.

6.Check drain hole for obstructions.

7.Inspect the condition of the descalers as outlined in this section and replace if necessary.

8.Mix the deliming solution according to the instructions for the chemical being used.

NOTE: Boiler water capacities vary between seven to nine gallons for both gas and electric models depending on the boiler size and BTU/KW rating.

NOTE: If deliming solution accidently comes in contact with steamer components, lightly rinse off with clean water.

A.Models with Blowdown Timer - Pour deliming solution into boiler shell. Proceed to step 9.

B.Models without Blowdown Timer - Turn off the incoming water supply. Turn the power switch ON to close the drain valve. Pour deliming solution into boiler shell. Proceed to step 9.

C.Models with Deliming Port Assembly - Before pouring deliming solution into boiler, clean the seating surfaces for the hand hole gasket and then install a new gasket. Position the hand hole plate and tighten down. Turn off the incoming water supply. Turn the power switch ON to close the drain valve. Open the deliming assembly valve and pour the deliming solution into the port. Close the deliming assembly valve and proceed to step 10.

9.Clean the seating surfaces for the hand hole gasket and then Install a new gasket. Position and tighten the hand hole plate.
