Sea Recovery SRC Aqua Matic 1400-2, Руководство пользователя, Страница: 102 / 223

Some Electric Motors supplied by Sea Recovery have permanently sealed and lubricated bearings. Others require
lubrication from time to time. If your Electric Motor has grease jerks at each end of the motor (over the front and
rear bearings), the bearings require lubrication every six months. Give three pumps of high temperature motor
bearing lubricant into each grease jerk. Use a Polyurea Base Grease such as Chevron SRI (Polyurea Base) or
Shell Dolium R (Polyurea Base). DO NOT USE LITHIUM OR SILICONE BASE GREASE.
T-Connector Pressure Pick-Up
Replace kinked hoses or tubes. Disconnect each end of the hose/tube and blow air through it to ensure that it is
not blocked. Replace if damaged.
Pressure Transducers
Pressure Transducers are irreparable and cannot be calibrated. If inoperable, check connections at the transducer
and printed circuit board to ensure that there is no visible corrosion, or loose connections.
Plankton Filter Element (Cleaning)
1. Unscrew the bowl counter-clockwise.
2. Remove the Plankton Filter Elements from the bowl.
3. Remove the O-Ring from the top of the bowl.
4. Clean the mesh screen filter elements with a bristle brush and water spray.
5. Wipe the O-Ring with a damp cloth.
6. Lightly lubricate the O-Ring.
7. Place the O-Ring back onto the bowl.
8. Insert the cleaned or new plankton filter elements into the bowls.
9. Screw the bowls on clockwise.
10. Hand tighten to seal the O-Ring. Do not use a wrench or other tool to tighten and do not over tighten. Over
tightening transfers stress to the lid and bowl threads, causing the lid or bowl to fail (e.g. crack or break) and
makes subsequent disassembly difficult.
Multi Media Filter Backwash
The Multi Media Filter contains fine gravel and #20 silica sand. This silica sand traps suspended solids larger than
20 micron. The top layer of the silica sand becomes packed with suspended solids and restricts flow through it.
When the silica sand becomes packed with suspended solids (as indicated by a loss of pressure), it must then be
back washed to waste. The back washing procedure fluffs the silica sand and dislodges the suspended solids from
the sand base. During back washing, the suspended solids are discharged to waste through the Multi Media Filter
Waste outlet. If replacing the media, the Multi Media Filter requires approximately 15 lbs. (7 kg) of small gravel
(1/8 x ¼ in. (3.27 x 6.35 mm), first on the bottom, then approximately 26 lbs. (12 kg) of #20 silica sand (on top of
the small gravel).
Note: New gravel and sand contain contaminates. The Multi Media Filter must be back washed prior to use.
1. Open the Inlet Sea Cock Valve.
2. Position the Rinse Clean Inlet Valve (if installed) to the normal operating position towards the Sea Strainer.
3. Position the Rinse Clean Outlet Valve (if installed) to the normal operating position towards the Brine Discharge
Thru-Hull Fitting.
4. Position the Multi Media Filter valves to Backwash.
5. In the Manual mode of operation, operate only the Booster Pump.
6. After 10 minutes of back washing, stop the Booster Pump.
7. Position the Multi Media Filter Valves to Rinse.
8. In the Manual mode of operation, operate only the Booster Pump.
9. After 5 minutes of rinsing, stop the Booster Pump.
10. Position the Multi Media Filter Valves to Normal Operation.
