Thank you for purchasing the Navtec System V Multi Function Panel. It is made of the highest quality materials available. The System V single function panel is expandable to a multi-function unit should you desire more hydraulic functions at a later date. The conversion kit part number is A310-SMC-01. Things to bear in mind while using the system are:
1. Do not over tighten the release knob (#l). This will damage the ball valve and ultimately cause pressure leakage. Only two fingers are necessary to close the valve fully.
2. Check the hydraulic oil periodically to insure cleanliness.
3. NEVER use brake fluid in the system. It will destroy all seals.

Installation:
Locate the panel position keeping in mind normal position of crew members while pumping. Cut the appropriate hole (see table p.1 in the PDF file) and mount the panel with 1/4"(6.35mm) round head stainless steel bolts. Use a high quality marine sealant between the panel and bulkhead to prevent leaks. Mount the separate reservoir with the hose fittings at the bottom. Be sure to leave room above the removable cap at the top of the reservoir for filling. See table lll for reservoir capacity and dimensions. If possible, the bottom of the reservoir should be above the pump as pump suction will be more positive, but this is not essential for satisfactory operation. In no case, however, should it be more than 4" below the pump intake (#4). Place the reservoir as close to the pump as possible to minimize the effect of pitch and heel.

Plumbing:
Connect either hose barb at the bottom of the reservoir with pump intake hose barb (#4 ) using the low pressure hose supplied. Be sure there is a plastic oil filter in this line. Connect the other hose barb on bottom of reservoir with hose barb (#7) on the back of the of the panel, using a second low pressure hose. A single high pressure reinforced hose or stainless steel tube (rated for at least 5,000 psi) must be run from the valve on the central panel to each operating cylinder. High pressure hose, cylinders and boom vangs are available from your Navtec distributor. If the panel is single function, the hose or tube runs from fitting (#5); if single gauge, multiple function, hose runs from I of 4 ports on 4-way selector valve (#6); if multiple function with multiple gauges, hose runs to cylinder from T-fitting on appropriate gauge block. [if 4-way valve is used (this is different than 4-way selector valve), consult your Navtec distributor or Navtec Inc. for plumbing instructions.

Oil and Filter:
Use #1 0 hydraulic oil or #1 0 non-detergent motor oil. (Detergents cause foaming). Never use brake fluid because it will affect the seals. Oil should be checked periodically for cleanliness. Any particulate matter in the oil will decrease the life of the moving parts and may also cause immediate malfunctions. The oil filter should be changed if there is any indication of pump skipping due to oil starvation.

Cylinders:
Standard Navtec cylinders are equipped with an air-pressure return. This return is pressurized through the "tire" valve at the clevis end of the cylinder. A bicycle pump or service station air hose can be used to charge the return up to 100 psi. The air pressure should be adjusted to give the desired rate of return. WARNING: Once charged, do not attempt to disassemble the cylinder. This should be done only by an authorized Navtec hydraulic service center or Navtec Inc. See table 11 in the PDF file for cylinder specifications.

Bleeding the System:
After installing the panel, cylinders and plumbing, oil should be added to the reservoir and the system bled of all air. Each cylinder and line must be bled separately.
Step 1 - Open release valve fully. If system is multifunction, select function to be bled first.
Step 2 - With hose attached to cylinder, extend cylinder fully. If there is air pressure in lower chamber, the cylinder will extend automatically.
Step 3 - Disconnect hose at cylinder. Note: always disconnect slowly to allow any remaining pressure to decrease slowly. Be prepared for possible oil drips.
Step 4 - Set valve to pump and pump, holding the hose end in a can to collect oil. When oil is bubble-free, reconnect hose to cylinder.
Step 5 - Pump cylinder all the way down (with cylinder detached from rigging). Then open release valve and allow cylinder to return fully.
Step 6 - Repeat above procedure for each cylinder and line.

Relief Valve Adjustment:
The relief valve '(#8) is set at the factory to approximately 4000 psi. Adjustment is provided by the 1 " (25mm) round threaded cap in the aluminum valve block at the back of the panel. Maximum release setting is 5000 psi. Turning the cap counter clockwise will lower the setting. Clockwise will raise it. The adjustment is about l000 psi per complete turn. To determine the setting without tensioning the rig, disconnect any cylinder from the rigging and pump that cylinder until it bottoms and the relief valve lifts which will be evident when continuous pumping fails to raise the gauge pressure. The maximum pressure observed is the relief valve setting.

Operating Instructions:
For a Single Function System (WITHOUT selector valve): To increase tension in the cylinder, make sure that the release valve (#l ) is closed. Do not over tighten. Doing so will shorten the life of the valve. Now pump. The valve body has a special zero-leakage check valve so no manual locking valve is necessary. To reduce tension, open the release valve. The Navtec designed needle valve allows very fine adjustment of the release rate. Remember, it is not necessary to turn very hard to close the valve.
For a Multi Function System (WITHOUT selector valve): This system operates the same way as the single function system (see above) except that the selector valve must be positioned before pumping or releasing tension. To position, turn the selector valve handle (#2) toward the valve port (at rear of the valve) to which the appropriate hose is attached. Function labels are available from Navtec at no charge.

The Gauge:
The Navtec gauge (#3) has a double ended needle so that two scales can be used. The top scale, which reads in thousands of pounds per square inch, is always included and indicates the pressure with in the cylinder and the connecting plumbing. A lower scale, which reads in thousands of pounds of force, can be overlaid on the gauge face if the cylinder size is known. These gauge face overlays are available from Navtec at no charge. Please specify cylinder size when ordering. The pressure within the system can be converted toactual force exerted by the cylinder using Table Ivin the PDF file or the formula below:

Pressure (lbs/inch2) x Cylinder area (inch2) = Force (lbs)

Gauges have a special backing card that is specially treated to provide night illumination. Lf charge does not provide enough light, recharge by passing flashlight beam slowly over gauge.
