The operating weight for MC units is 250 pounds, and for HC units is 295 pounds. • Make sure you have adequate means for lifting the cooler in place. • Make sure the mounting surface is level in all directions. • Make sure any ductwork and electrical needs comply with local, state, county, and federal codes. Caution: All electrical in- with local building and safety codes, and must be stallations by must comply performed quafified personnel only. Mounting The blower module and the media module can be separated before mounting by removing four bolts and one shipping screw -see drawing below. B°lts_ w Placement and Securing your MasterCo'bl evaporative port the unit and secure it to the roof For High-Performance models HC43. HC44 HC63 and HC54 we recommend that a fuji stand be constructed in such a manner as to support the entire perimeter of the cooler. A leg kit only may not provide adequate support for these mods!s due to their increased size and weight. Place the cooler over the roof jack and position so that it is level. Carefully seal the space between the roof jack and bottom of cooler with caulking compound, silicone, asphalt or industrial sealing tape to prevent air leakage. Then carefully seal the roof jack to roof with asphalt or caulking compound to prevent air leakage from cooler or rain water from leaking into roof. (See Figure ! ). There should be 24 inches clearance on all sides of the cooler for maintenance. For maximum cooling performance and even water distribution, the cooler must be level. The base of the cooler at the drain fitting should have at least 4" clearance to allow drain installation. Electrical Connections For the convenience of thermostat control, we recommend installing a MasterStat TM Universal Cooler Control Kit, Model CCl000A. Complete installation instructions are furnished with the CCl000A Kit. For electrical connections to a rotary wall switch, use the following instructions: Locate the junction box installed in the dry module. Junction box is to be installed with the receptacle facing away from the pad. Make cedain all electrical cords are clear of the belt, water, pulleys and blower wheel. Note that there are two plug-ins, one for the motor and one for the pump. The building power supply must be connected to this junction box to provide power to the motor and pump. The wiring diagram in Figure 1 shows how the junction box receptacle should be connected to the power supply. Make sure contro switch and circuit breaker are in the OFF position. Low voltage electrical supply (below 105 V) may cause insufficient water supply to pad. Caution: Turn off all electrical power to the cooler before attempting to install, open, or service your cooler. Grounding Install a ground wire to suitable ground according to local codes. Install Motor NOTE: A special MasterCool motor kit is necessary for installation due to the custom designed receptacle in the junction box. 1. Adjust motor cradle spacing. 2. Place motor in cradle (see Figure 2). 3. Place straps over each end, connect to cradle and tighten. 4. Align sheave (motor pulley) with blower pulley by moving sheave in and out on motor shaft until visual alignment is achieved. Tighten alignment set screw to 125 in-lbs. Do not adjust to the point where the motor sheave comes in contact with the motor face plate (see Figure 2). Belt tension should be adjusted sothe belt will deflect 1/2 to 3/4inch at the center of the span per Figure 3. Re-adjust belt tension after any pulley adjustment. Replace worn or damaged belts. SUPPORT BRACKETS ADJUSTMENT MOTOR STRAPS BRACKET Figure Rgu.,2 3 Figure I The duct opening for the 63/64 units should be about 20" x 20". The cooler discharge opening for these models is 19-3/4 x 19-3/4". For the 43/44 units the duct opening should be about 18" x 18". The cooler discharge opening for these models is 17-3/4" x 17-3/4". If the cooler is to be mounted on the roof, construct a suitable roof stand to support the entire weight of the cooler. (The roof jack or ducting should NOT be used to support any weight of the unit). For models MC63 or MC64 our #785 leg kit, sold separately as an accessory, will adequately sup- cooler.

Do not adjust belt tension by changing diameter of adjustable sheave. Adjust belt tension only by adjusting motor brackeL Rotate blower wheel by hand to see that it moves freely without rubbing against housing. Check motor mounting to be sure all screws and nuts are tightened down. If cooler is connected to ductwork, air delivery and motor amperage will be decreased due to increased duct resistance. To compensate for this, the motor pulley is adjusted out or in, using an ammeter to check motor amperage. For maximum air flow check motor amperage with all service panels in place. To prevent overloading of the motor, check amperage with all windows and doors open and all relief systems operating. Tighten pulley set screw to 125 in-lbs. A qualified serviceman is required to adjust mOtor before start-up. maximum amperage output as stamped on the moCaution: Do not exceed tor specification plate or motor can overload. Only qualified persons with proper electrical equipment and knowledge should adjust variable pitch sheaves. Do not allow water to get on the motor, as it will burn out the windings. Connect Water Supply Connect water line to cooler as follows: • A water valve should be installed at a convenient location, to allow the water supply to be tu reed on and off. 1/4" tubing is used to provide water to the cooler. A water connector kit, available from your dealer provides the necessary items. • Install float valve in the side panel of the wet section opposite the pump. • Place tube nut and ferrule over end of tubing. • Insert tube intofloat valve, and tighten to secure. NOTE: Soft water equipment should not be attached to any water lines going to a cooler. "Soft Water" will cause corrosion and decrease effective life of cooler. Figure 5 COMPRESSION NUT _ FERRULE FLOAT ROD WASHERS _. Fasten 1/4 inch water supply line to cooter stand using tubing clamp and self-drilling screw. Locate tubing clamp 18 inches or less from water supply line entry into cabinet. (See Figure 5A) Note on multi-speed switches: A switch with separate terminals for the pump is recommended. Install Overflow Standpipe and Drain Line Install overflow drain bushing in bottom wet section on the right side. Screw plastic overflow standpipe into the drain bushing and tighten snugly. Slide rubber washer over drain bushing, push through bottom of cooler, and tighten nut. Connect a permanent drain (copper/pvc/garden hose) to the drain bushing for draining the unit and overflow protection. Drain should be in accordance with local plumbing codes. _3ELF-ORILUNG SCREW 1/4" WATER SUPPLY UNE Faucet Use Connect water line to water supply, as follows (refer to Figure 6). • Install a sillcock and water valve on faucet, as shown. Place tubing nut and ferrule on tube end and insert in valve. Tighten nuts on valve and tube. If faucet is not to be used for water supply, install valve on water line to be used. Follow instructions above for securing tubing to valve. Rgure 4 Rgure 6 -, -,=_-^/_-_TUBING Adjusting Water Level and Float Valve Fill reservoir as follows: • Turn water supply on. Check for good pressure and flow from float valve. • When float valve shuts off, check water level. Water level should be from 1/2 to 1 inch below top edge of overflow standpipe. It may be necessary to adjust float valve by bending the rod (refer to Figure 5). • Check reservoir and all connections for leaks. Install Bleed-Off A bleed-off system is provided with your MasterCool cooler. We recommend the bleed-off be installed and maintained while operating this unit. its purpose is to eliminate a small quantity of water from racirculation thus reducing scale build-up. Install bleed-off as Figure 7 follows: • Install 1/4" black plastic tubing into pumpasshown in t/4" Figure 7. TUBE • Insert smaller / black plastic tubing into 1/4" tubing as shown in Figure 7. Adjust bleed-off by shortening small tube to get the proper bleed rate shown below. Disposal of bleed-off water should comply with local codes. Use of chemical additives or any water treatment other than bleed-off is not recommended for this cooler. Failure to use the bleed-off with MasterCool pad greatly increases the mineral deposits and reduces the expected life of the MasterCool pad, and could result in early replacement of pad at your expense.
